Spoiler Warning: There are spoilers ahead for Star Trek: Discovery Seasons 1-4 and the trailers and teasers for Season 5.
We’re going to have to delay my review of the latest Star Trek: Picard episode by a day or two in order to do something that I rarely do here on the website: cover some breaking news. If you haven’t heard, let me be the bearer of what may or may not – depending on your perspective – be a bit of bad news: Star Trek: Discovery is going to end after its fifth season.
Forgive me for thinking negatively, but as soon as I heard that announcement, I felt a sinking feeling in my gut. Since filming wrapped on Discovery’s fifth season late last year, no live-action Star Trek has been in production for the first time in a couple of years. Not only that, but Picard’s ongoing third season is going to be that show’s swansong… and despite a spectacular first season, there’s been no news on a third season renewal for Strange New Worlds, at least at time of writing, even though production on Season 2 wrapped months ago. So could this be, as I fear, the beginning of the end for Star Trek in its modern incarnation?
How much life is left in the Star Trek universe?
Discovery brought Star Trek back to its small screen home in 2017 after twelve years in the wilderness. The show served as a launchpad for the Star Trek franchise as it exists today – and it’s highly likely that we would never have seen Picard, Lower Decks, Prodigy, or of course Strange New Worlds were it not for the trail that Discovery blazed. But with its cancellation after Season 5 – which is due to be broadcast sometime in early 2024 – is Star Trek in a better or more secure place than it was in 2017… or in 2005?
I’d argue that it isn’t.
Shortly after new year, I published a piece here on the website titled 2022: A Great and Terrible Year for Star Trek, in which I took a look at what I considered to be the highs and (considerable) lows that the franchise endured over the course of a rollercoaster year. Although there was a lot to say, perhaps my biggest conclusion was simply this: franchise fatigue is beginning to set in. It’s through that lens that I must view the news of Discovery’s imminent ending.
The final shot of Discovery’s fourth season finale.
Unlike with Enterprise in 2005, it’s my hope that Discovery’s writers will have known the end was coming well enough in advance to have planned out a conclusive ending for the series and its characters. Enterprise’s finale was divisive among fans, and the show’s final season seemed to leave more than a few characters and storylines up in the air by the time the curtain fell. If this recently-announced news had been known to the producers and creative team, hopefully they will have been able to put together an ending worthy of the show and its great cast of characters.
And as I’ve said more than once: it’s infinitely better for a show to end leaving its audience wanting more, lamenting that we didn’t get “just one more season,” rather than dragging on too long and having us regret that the end didn’t come earlier! Discovery has been an imperfect production, don’t get me wrong, but with the current state of Star Trek being what it is… maybe this is simply the right time for the show to come to an end. If there weren’t great ideas on the table for future story arcs, then I’d rather it came to a close with one last hurrah instead of dragging on ad infinitum.

Star Trek can’t keep up the pace that we saw in 2022, where more than fifty episodes across five shows all debuted in a single calendar year. It’s just too much – and it risks putting off new viewers, who are precisely the people that Paramount needs to convince to tune in if Paramount+ is to have a snowball’s chance in hell of surviving the streaming wars. Making Star Trek too dense, too convoluted, and just too large is what’s been happening over the last few years, so stepping back from that shouldn’t be seen as a bad thing. If anything, it should be a net positive for the franchise.
With Picard also coming to an end, there’s the potential to perhaps scale back Star Trek and refocus. Take what worked about the shows over the last few years and hone it, disregard failed experiments, and have Star Trek operate in a similar fashion to other streaming franchises – with a focus on quality over quantity.
Star Trek: Picard is also coming to the end of its run.
But is that Paramount’s goal? With two live-action shows coming to an end, there’s the potential to put more money and energy into Strange New Worlds, for example, as that show was very well-received. But with no third season having been announced so far… I can’t shake the feeling that this really could be the beginning of the end for the franchise as a whole.
Depending on how things are scheduled, there’s enough Star Trek in production or post-production to coast through into the first half of 2024. But what then? A third season of Strange New Worlds – if one is to be produced – might also debut that same year… but 2025 could end up being like 2005: the end of the road.
Is this moment akin to 2005?
If that were to happen, Paramount only has itself to blame. The corporation has mismanaged both the Star Trek franchise and its streaming platform in catastrophic fashion, seemingly led by the most inept team of morons to ever assemble in a boardroom. Before Discovery had even been conceived, an ageing corporate board with no knowledge or understanding of streaming or the internet saw the success of Netflix and said “make me one of those.” CBS All Access was born – and Star Trek was tapped to be its flagship franchise.
But was Star Trek ever big enough to place such a burden upon it? Even if Discovery had been flawless and had landed with minimal controversy, pinning the profitability of a streaming platform on its success was always a bad idea. It isn’t Discovery’s fault that CBS All Access – as Paramount+ used to be known – didn’t become the “next big thing” in streaming… and it isn’t Discovery’s fault that Paramount+ remains massively unprofitable today.
Discovery was created to be the flagship series for CBS All Access.
Paramount is in the wrong business. The board is right about one thing: streaming is the future. But they jumped into that market a decade too late, unprepared, and without the technical know-how or infrastructure to really make it work. The only thing CBS All Access/Paramount+ had going for it were shows like Star Trek – but I think Paramount is belatedly learning that the Star Trek franchise simply doesn’t have the mainstream appeal to carry an entire streaming platform.
So what does all of this mean for Star Trek’s future? Maybe it’s too early to hit the panic button… but I confess that I feel echoes of 2005. It’s been surprising to me that no spin-offs or new projects have been announced, and in a way, the announcement of Discovery’s cancellation was another opportunity to do so. The tone would be very different if the press release had stated that “Discovery is coming to an end… but Starfleet Academy or Captain Seven are entering production.”
Does Alex Kurtzman have a surprise up his sleeve?
So here we are. After a creditable six-year run, and numerous cancellation scares, Discovery will be coming to an end. Its imminent fifth season actually looks fantastic – and if it makes good on its promise of telling a different kind of story, perhaps in another world that could have set the stage for the show’s continuation. Perhaps the tragedy here will be that Discovery changed tack too late – that four whole seasons of “the galaxy is in danger and only Burnham and the crew can save it!” was just too much. That would certainly be my assessment, and as enjoyable as parts of Season 4 were, maybe if a different kind of adventure had been written last time around, we could’ve gotten an extra season or two.
There are a lot of unanswered questions. What of the backdoor pilot for a Starfleet Academy series that we seemed to get partway through Season 4? If Star Trek as a whole continues, will another series pick up Discovery’s 32nd Century setting – or does Paramount consider the far future to have been a bit of a misfire? Will Star Trek continue at all after Strange New Worlds Season 2 and Discovery Season 5? Is anyone at Paramount ready for a difficult conversation about what’s going wrong?
Paramount ought to reconsider many of its recent decisions…
I’m not thrilled to learn that Discovery won’t continue. Although not every season and every character fully stuck the landing, there’s been some fantastic entertainment along the way – episodes and moments within episodes that hit all of the high notes that we know Star Trek can. Moreover, by the time the curtain fell on Season 4, I felt that Discovery had finally turned a corner. Having settled Burnham into the captain’s chair, and told a story about seeking out new life – the very core of Starfleet’s mission – it felt that the show had finally achieved its potential. Season 5 will hopefully capitalise on this – but it will be short-lived, with only ten episodes left for the series to shine.
The history of Star Trek is one of stepping-stones: series and films that lead to new, different, and often better things. Just as Enterprise and the Kelvin films led to Discovery, so too has Discovery led to Picard, Lower Decks, Prodigy, and Strange New Worlds. Whether these shows will lead, in turn, to new things, or whether the trail will go cold for a while, Discovery played its part. It may not have always done so perfectly, but I’m confident that its place in the franchise’s history is assured – and I suspect that at least some of its critics will be won over if they give it a second chance!
I’m still looking forward to Season 5 – but it’s now a rather bittersweet feeling, knowing it will be our final outing with Captain Burnham and the crew. Not to mention that this news has massively increased concerns for the overall direction – and indeed the future – of the Star Trek franchise as a whole.

Spoiler Warning: There are spoilers ahead for Star Trek: Discovery Seasons 1-4 and the trailers, teasers, and announcements for Season 5. Minor spoilers are also present for The Next Generation and Deep Space Nine.
At New York Comic-Con in October, we caught another glimpse of Star Trek: Discovery’s fifth season. The news earlier this week that filming has officially wrapped makes it seem like a great time to take a look at the teaser trailer and see what – if anything – we might be able to glean about the new story!
So to begin with, filming has just wrapped on Discovery Season 5 at time of writing. With Picard Season 3 and Strange New Worlds Season 2 both also well into post-production, there’s now no live-action Star Trek being worked on… at least, nothing has been officially announced. So that’s definitely something interesting – and while I’m expecting a Season 3 announcement for Strange New Worlds at literally any moment considering how well Season 1 was received, it’s definitely noteworthy that, at least in terms of live-action production, Star Trek seems to be entering a quiet period.

At Star Trek Day back in September, we were treated to a set tour with Wilson Cruz, but I was a little surprised that the set tour and a single still photo were all that there was to show for Discovery at that point. I guess Paramount was saving this teaser trailer for Comic-Con, though, which came barely a month later. I’m glad we finally have something to get stuck into, even though I would guess that Discovery Season 5 may not hit our screens until after Picard and Strange New Worlds, potentially meaning it could be up to a year away.
Earlier in the year I wrote a piece about my “biggest wish” for Discovery’s fifth season. If you missed it, I can summarise it thusly: I don’t want Discovery to try to tell another “the galaxy is in danger and only Burnham and the crew can save it!!!” type of story. We’ve had four of those across the show’s first four seasons, and I know I wasn’t the only one in the weeks leading up to Season 4 to say that it was already beginning to verge on the repetitive. Trying to cram another story into that same creaking framework would be too much… and I’m pleased to say that, based on both this teaser trailer and the official synopsis of Season 5, Discovery seems to be trying something different this time around.
Here’s to a different kind of story in Season 5!
The teaser trailer certainly contained a lot of action – explosions, fire, injuries, weapons, masked alien adversaries, and a fair amount of running away. But these disconnected moments seem – if the voiceover and selected clips can be believed, at any rate – to be in service to a new and different kind of story, possibly one about… treasure hunting!
I know that we don’t have a lot to go on in a teaser trailer that was less than a minute long, so I hope I’m not being misled or getting too excited based on a single line that could, I admit, be open to other interpretations. But I really think that the idea of a treasure hunt could be a good one for Discovery if that’s the route that the new season will go down. At the very least it represents a change from what the show has done before, and as I’ve said previously, Discovery doesn’t need to keep re-using the same “horrible galactic disaster” narrative in order to tell stories that are exciting.
I hope that this rather desolate location isn’t indicative of another galactic-scale threat or disaster.
As viewers, our investment in a story is not inexorably tied to a sense of scale. On the contrary, some of the best films and television shows of all time have told character-centric stories that were a million miles away from civilisation-ending disasters – and some of the worst and most boring works of entertainment have tried and failed to compensate for lacklustre storytelling by going too big on the scale of the threat.
Past iterations of the Star Trek franchise also used the “galaxy is in danger” story archetype very sparingly, when you think about it, and some of the most well-remembered films and episodes don’t focus on villains or disasters on anywhere near that scale. If Discovery really is willing to set aside this framework for Season 5 – a framework that I would argue it has pushed to the limit – I think that can only be to the show’s overall benefit. Based on this teaser I’m cautiously optimistic that we’re going to get a main story that goes in a different direction. Fingers crossed, anyway!

Some of the clips in the teaser tie into this theme of an “epic adventure across the galaxy,” to quote the official synopsis released by Paramount. We saw a slightly different look at Burnham on her speeder bike from the previously-released photo, and it seems as though Stamets will be joining her for that part of the quest! Stamets was relegated to a minor role in Season 4, missing out on key storylines, even those which involved Gray, Adira, and Dr Culber – so seeing him back in action will definitely feel good!
We also briefly saw two characters who may be competitors or adversaries as Captain Burnham and the crew race to solve this mystery. The characters’ names have been given as Moll and L’ak, and their official descriptions read somewhat like a 32nd Century Bonnie and Clyde! Their backgrounds as couriers could give them a connection to both Book and Burnham – the latter having spent roughly a year as a courier after arriving in the 32nd Century before the ship and the rest of the crew joined her. There’s scope for some drama there, and I wouldn’t be surprised if one or both characters were known to Book, at least.

I can’t tell what planet L’ak hails from, though his design feels at least somewhat familiar. There’s something Kelpien about his look, but at the same time I don’t think he is a Kelpien. I can’t put my finger on why he looks so familiar, though! Perhaps some kind of connection to an established Star Trek race or character will become apparent once we meet him. Moll, on the other hand, is giving me flashbacks to Farscape’s Chiana – I think that’s just the hairstyle, though!
There were a few clips of ancient-looking statues and ruins that seem to connect with this theme of ancient mysteries and treasure-hunting. I’m reminded of episodes like Captain’s Holiday, The Chase, and Gambit from The Next Generation, and the archaeological sequences set in the ruins of the Bajoran city of B’hala in Deep Space Nine. Jean-Luc Picard studied archaeology, and set off to uncover more than one ancient mystery in his time! Perhaps the story of the season will play out in a similar fashion – and there could even be references to some of the individuals or events in some of those earlier archaeological stories. Discovery hasn’t been big on drawing these kinds of connections, but some smaller references have made it to screen, so it’s possible at least!

It seems that the enigmatic Dr Kovich will be back for Season 5 – and after an occasionally frustrating time with this character, I have to say I hope that we’ll learn a little more about him. I haven’t forgiven Discovery’s writers for Kovich’s line in Season 4 that he had “more important things” to do than join the mission to contact Unknown Species 10-C; the fact that that line wasn’t paid off in any way at all wasn’t great. Despite appearing in seven episodes across two seasons, Dr Kovich’s role within the hierarchy of Starfleet and the Federation is still unknown.
I like the idea of Dr Kovich being the one to set Captain Burnham on the right path to begin this quest, as I think he’s the kind of character who could conceivably know something about whatever this mystery is that needs to be unravelled. But I hope that we learn more about Kovich himself, including how he seems to know so much about some of the subjects that he’s an expert in. What rank does he have, for example? Is he, as I’ve suspected since Season 3, an operative of Section 31? Dr Kovich is in danger of become a bit of a joke; a character used only for exposition and whose ambiguous background grows to accommodate anything a story needs – teacher, administrator, psychiatrist… I think we need to pin down who he is and what his official role is!

One character who we barely glimpsed in the trailer is new series regular Captain Rayner. This Romulan or Vulcan (at least by appearance) is described as a “gruff, smart Starfleet Captain” who had a “track record of wartime success,” but struggles in peacetime. Rayner sounds like he’s being set up to be a kind of antagonist for Captain Burnham to butt heads with; perhaps a Starfleet officer who doesn’t appreciate her lax attitude to rules nor her style of command.
We had a similar setup, in some respects anyway, with President Rillak last season, and I was on tenterhooks waiting to see if she’d betray Burnham and the crew – or if she was involved in some way with the DMA. Since arriving in the 32nd Century, senior Starfleet and Federation personnel haven’t fallen into the Star Trek trope of being the “bad admiral,” so I wonder if there could be more to this Captain Rayner that his official description might suggest. It does raise an interesting question, though: what ship will Captain Rayner command? The USS Discovery already has two officers on board who hold the rank of captain: Burnham and Saru. Surely Rayner can’t also be assigned to the USS Discovery – but if he isn’t, how could we expect to see him as a series regular?
Captain Rayner.
Sticking with characters, let’s talk about Tilly. I talked about this after Star Trek Day, when Mary Wiseman appeared during the behind-the-scenes look at Season 5, but I hope that Tilly’s apparent return to the USS Discovery doesn’t undermine the emotional story she went through in Season 4 – a storyline that led to her leaving the ship for a role at Starfleet Academy.
We didn’t see a lot from Tilly in the trailer, but she was present for several clips, including aboard the USS Discovery. She could be “just visiting,” of course, or accompanying one or more of her cadets, but I’m not sure. I get the impression that something has changed for Tilly behind the scenes (yet again) and a reversal of a previously-established arc could be coming. As much as I love Tilly and want to see her continue on the show, her departure in Season 4 felt final… but moreover, it felt right for her character. Undoing that would not be my choice. I wonder if plans may have changed regarding the rumoured but still unannounced Starfleet Academy series – a series which could potentially have included Tilly. If last season’s All Is Possible (an episode that felt like a possible backdoor pilot) wasn’t as well-received as hoped, perhaps a rethink of that series and which characters it might include is underway. That’s something we’ll have to consider in more depth on another occasion!
Is Tilly back?
We saw members of the bridge crew at their posts and on an away mission in the teaser, and I’ll repeat what I said in the run-up to both Seasons 3 and 4: there’s still scope to do more with some of these characters. With the return of characters like T’Rina, Admiral Vance, and President Rillak, Discovery is definitely building up a good roster of secondary characters, so it would be neat to see at least one of the bridge crew given a storyline or sub-plot this season.
And that raises another question: will Season 5 retain Discovery’s heavy plot armour for all of the named characters? After so many disasters, conflicts, and dangerous assignments since the crew arrived in the 32nd Century, it’s a miracle that everyone has survived! As I wrote in the run-up to last season, audience expectations are changing in the aftermath of shows like The Walking Dead and Game of Thrones, so giving every character heavy plot armour to survive deadly situations doesn’t really work any more. As sad as it would be to lose anyone – even one of the secondary characters that we don’t know so well – I think it’s something Discovery’s writers ought to at least consider doing.

One thing that I found interesting in the trailer is the puzzle box. The markings on the apparently wooden box were unfamiliar to me, but they look suitably “alien.” They could be Vulcan, perhaps, or Ferengi, or even from a planet like Risa. Whether the puzzle box will be an important macguffin in the story – or whether it was little more than a fun visual metaphor for the trailer – isn’t clear at this stage. Will it be an important artefact that the crew spend much of the season chasing down or trying to figure out?
The mysterious puzzle box…
But there is something more to say about the sequences in which the puzzle box is prominently featured. Look at the fingers that are moving the pieces into position. Do they look familiar at all? They absolutely could belong to an alien – like the new character of L’ak, for instance. But something about those fingers says “android” to me; they remind me a lot of how Data’s hands looked in The Next Generation. Could this mystery connect in some way to Data, Lore, or the Coppelius synths from Star Trek: Picard? Maybe that’s a complete overreach… but you never know!
…and a closer look at the fingers of whoever is using it.
It’s hard to know what else to say at this stage, really. Some of the clips in the trailer were very short, and without more context it’s hard to say more other than all of the characters from Season 4 seem to be returning. I’ll be curious to see more from President Rillak, who was a fun addition last time, and it’s my firm hope that Discovery will find a way to settle the relationship between Book and Burnham – their relationship drama was not one of the better aspects of Season 4. Book seems to be aboard the USS Discovery in the trailer, so there’s hope in that regard!
For a first look, the teaser trailer did a good job at getting me interested for Season 5. I like the idea of the show striking out and trying something genuinely new and different as it enters its fifth season – giving a bit of a refresh to a show that’s been running since 2017 and is quickly approaching its sixty-fifth episode is no small feat, and I’m rooting for Discovery to succeed.
Although there’s a lot of post-production work to be done, I’m hopeful that we’ll see Discovery Season 5 on our screens in 2023. If I had to guess, I’d say that the show could be targeting a broadcast next autumn, with Picard Season 3 and Strange New Worlds Season 2 going first. If we get any more big news or another trailer (which we surely will before the season arrives) I hope you’ll check back as I daresay I’ll have more to say. For now, I hope this was a fun look ahead to Season 5!

Spoiler Warning: There are spoilers ahead for Star Trek: Discovery Seasons 1-4.
With Picard Season 2 ongoing, Strange New Worlds Season 1 hot on its heels, and Prodigy and Lower Decks still to come this year, it might seem premature to be thinking about Discovery Season 5 already! But as I was writing up the final part of my Season 4 theory list, it got me thinking. Season 4 wasn’t bad, all things considered. It had some storylines that disappointed or underwhelmed, but there are some genuinely outstanding episodes in the mix as well – and it ended on a very emotional and exciting high note.
It’s never too early to look ahead, and before production gets fully underway on Discovery’s next outing, I wanted to share my thoughts and opinions about where the show could go from here, and what I’d like to see next. That’s what this article will be about – but stay tuned for a more in-depth look at Season 4 and some of its story elements in the weeks and months ahead.
The USS Mitchell in the Season 4 finale.
For me, the single biggest wish I have for Discovery Season 5 is that it steps away from the “apocalyptic, galaxy-ending threat” story archetype that has been used in different ways across all four seasons of the show so far. We’ve gone through the Klingon war in Season 1, Control and the Red Angel in Season 2, the Burn and the Emerald Chain in Season 3, and finally the DMA and Unknown Species 10-C in Season 4. It’s time to give Captain Burnham and the crew a break, and for the series to try using a genuinely different formula instead of slapping a new coat of paint on the old one.
Just because a story is smaller in scale doesn’t make it any less emotional, exciting, tense, or dramatic, and I think that’s a lesson some of Discovery’s writers and producers could do with taking to heart. How we as the audience respond to a work of fiction is guided not by how massive the monster is or how big the explosions are going to be, but by how the characters we’re rooting for react. Their emotions become our emotions, their investment in the world around them becomes our investment, and so on. A story about a group of people working in an office, friends going on a road trip, or star-crossed lovers from rival families aren’t smaller, less exciting, and worse because they don’t have the backdrop of a world-ending disaster spurring them on. And conversely, some of the worst and least-exciting films and TV shows I’ve ever seen went over-the-top with the size and scale of the disaster the characters were facing.
The Burn was the driving force for much of Season 3.
Past iterations of Star Trek used these kinds of apocalyptic stories pretty sparingly, when you look back on it. It’s only Deep Space Nine’s Dominion War arc, which lasted for three seasons, that comes close to being as long and drawn-out an affair, and even within the framework of the Dominion War, DS9 found ways to tell very different and fun one-off stories. Things like the Borg incursions that Captain Picard and his crew had to deal with were either two-parters or one-off films, and they work well in that format.
Picard and the crew of the Enterprise-D still found other ways to be entertaining, and many of The Next Generation’s standalone episodes have gone on to be considered iconic, even those that had a far smaller focus than blockbuster outings like The Best of Both Worlds. This doesn’t mean ditching the season-long story arcs or returning to an episodic format, because I think Discovery has done some interesting and neat things with its serialised stories. But it does mean choosing season-long storylines and narrative arcs that are different in a fundamental way to what the show has tried already.
The DMA was the big threat in Season 4.
Practically any format can become bland and unexciting when overused, no matter how much fun it might’ve been in its original incarnation or at its best moments. It’s a challenge to keep any television series feeling fresh as it enters its fifth season and races toward its sixty-fifth episode, and there are many examples of shows that ran out of steam somewhere along the way. Heck, I have an entire list of television shows that either ran too long or wore out their concepts, and I can think of many more that I could’ve included.
Even Star Trek has hit the wall in the past, running out of energy and failing to keep audiences engaged. By the time Enterprise was willing to try new things in its third and fourth seasons, for example, the franchise was already in such a steep decline that cancellation was inevitable. To Paramount’s credit, lessons have been learned from what happened in 2005 in terms of the way the franchise as a whole operates. Different series are telling stories in their own ways, appealing to broader audiences, and Star Trek as a whole feels varied and diverse. But Discovery on its own doesn’t… and it’s right on the verge of becoming repetitive.
The USS Discovery in Season 4.
I was far from the only commentator to make the point prior to Season 4 that another “galactic threat” storyline felt samey, coming off the back of three similar narrative frameworks, and I’m sure I won’t be the only one to say that re-using that format a fifth time will be a bridge too far. Making use of the newly-established 32nd Century in different ways, and telling a story that may be smaller in scale but that’s just as impactful, emotional, and entertaining, will be the key challenges that I’d like the writers to tackle in Season 5.
The theme of rebuilding in the aftermath of a disaster was something we only saw Season 4 tackle in the briefest and barest of ways right at the beginning of the season, but this could be a concept that the show puts to much better use next time around. Discovery could follow Captain Burnham as she and the crew jump to different worlds, delivering dilithium, solving problems, flying the flag for the Federation… and most importantly, bringing hope to a galaxy that’s been through a lot.
The flag of the Federation…
This is what I’d hoped Season 4 would do, to be honest. The idea of restoring the Federation from the incredibly weakened state it was in when we encountered it is far too important and interesting to be relegated to something that happens off-screen, and I felt even before Season 4 had aired a single episode that this concept offered so much scope for emotional, exciting, and varied storytelling. Discovery could hop to different planets, combining the inclusion of new and visually different alien races (like Season 4’s “butterfly” aliens) with the reintroduction of classic races.
Catching up with some of the factions we remember from past iterations of Star Trek is also something I’ve been wanting Discovery to do for two seasons now. We’ve caught glimpses of races like the Ferengi and Andorians, and heard others mentioned in dialogue and log recordings, but we haven’t actually spent a lot of time with practically any of them. Finding out what became of fan-favourites not only in the years after the Burn, but in the centuries before that event took place, is something that I think a lot of Trekkies would be interested in.
We caught glimpses of familiar races… but Discovery didn’t find time to explore most of them in any detail.
If the 32nd Century is going to be a major setting for the franchise going forward, this kind of world-building is important. Just like how The Next Generation laid the groundwork for Deep Space Nine through its introduction of the Cardassians and Bajorans, so too could Discovery introduce us to planets, races, and technologies that future spin-offs and Star Trek projects could expand upon.
Part of that world-building can be done in a serialised story that looks at how the Federation can be rebuilt in the aftermath of the disasters it has already faced; introducing another new disaster to avert or recover from is simply not needed at this point. From the point of view of the characters, throwing them into another extreme situation would also be problematic, and would take the storytelling close to soap-opera levels.
Owosekun, Saru, and Detmer.
Discovery has, to its credit, attempted to show how some of the events that its characters have gone through have impacted their mental health. Some of these stories have been underdeveloped – Detmer’s in Season 3 and Dr Culber’s in Season 4 being the most egregious examples. But even with this kind of attempted mental health focus, there’s a limit on what we could expect characters to go through and still be alright when they come out the other end.
To be fair, that’s a line that the Star Trek franchise has crossed in the past with characters like Miles O’Brien, for example, who seemed to survive a lot of traumatic events only to be back to normal the next week! But as shows like Picard have demonstrated with characters like Seven of Nine and Jean-Luc Picard himself, it can be incredibly cathartic to revisit some of these characters and give them meaningful, lasting development. But we’re drifting off-topic!
Captain Burnham in Season 4.
Star Trek’s galaxy is vast, and as we saw in Season 4 with the inclusion of races like the Abronians and Unknown Species 10-C, even in the 32nd Century there’s still a heck of a lot that Starfleet doesn’t know about it. There’s scope for Captain Burnham and the crew to get back to exploring for its own sake, as well as using their Spore Drive to reach parts of the galaxy that it would be difficult for the Federation to do otherwise. There’s the potential for the crew to bring hope to far-flung Federation outposts after the Burn, the Emerald Chain, and the DMA have had such a devastating impact… and it’s worthwhile telling stories like that.
Even if Season 5 doesn’t do much of that rebuilding or exploring, I’m still hopeful that whatever stories it chooses to tell won’t feel repetitive and won’t recycle the same basic story framework that we’ve seen throughout the show’s entire run to date. Discovery could do so much to expand our understanding of the Star Trek galaxy; even more so in a 32nd Century setting that is wholly unconstrained by prior canon. Shooting this far forwards in time was a great way for the show’s writers and producers to give themselves new opportunities to play in the vast sandbox that we call the Star Trek galaxy – so now would be a great time to take advantage of that.
As I look ahead to Season 5, I feel hopeful and optimistic. Season 4 had some problems, but generally it was an improvement over Season 3 and it ended in truly spectacular fashion. There’s potential for what comes next to build on that, and if the series can avoid retreading too much old ground, Season 5 could be Discovery’s best outing yet.
Star Trek: Discovery Seasons 1-4 are available to stream now on Paramount+ where the platform is available and via a patchwork of video-on-demand and pay-to-view streaming platforms in the rest of the world. The series is also available on DVD and Blu-ray. The Star Trek franchise – including Discovery and all other properties mentioned above – is the copyright of Paramount Global.

Spoiler Warning: There are spoilers ahead for Star Trek: Discovery Seasons 1-4. Spoilers are also present for the following Star Trek productions: Picard Season 2, Voyager, Enterprise, and The Next Generation.
Discovery’s fourth season concluded just over a month ago, but for some reason I’d forgotten to wrap up my theory list! I blame the oversight on the excitement of Picard’s second season overlapping Discovery for the final few episodes… and, perhaps, the issues surrounding Strange New Worlds’ international broadcast. Regardless, we’re here now! So let’s get on with it, shall we?
In my review, I said that Coming Home was probably the high point of the season, and while the episode wasn’t perfect, it was a great way to bring an occasionally frustrating season to a close! Some of the complaints and criticisms that I made were more to do with Season 4 as a whole rather than Coming Home itself, and while we’ll touch on some of those points today, please stay tuned because I hope to write up my full thoughts on the entirety of Season 4 in the weeks ahead.
Coming Home was an explosive end to the season.
The theory list had grown quite long across Season 4, peaking in week 11 where I had 36 different theories in play – with varying levels of plausibility! By the time we got to the season finale that number had dipped somewhat, and there were 23 theories on the list going into Coming Home. I’ll be recapping each of them on this occasion, as well as three production-side theories that were also in play.
Keep an eye out for several of them to return in the run-up to Season 5, because a few theories that weren’t outright debunked (or even touched on at all for much of Season 4) still feel plausible and interesting to me!
For now, let’s start with the sole theory that was confirmed in the season finale. We’ll then look at the debunkings, the production-side theories, and the few that remain on the table going into Season 5.
Confirmed theory: Book and Burnham got back together.
Burnham and Book embrace near the end of the episode.
This theory was one that I was desperately hoping would make it to screen! In short, the “Burnham relationship drama” angle that Season 4 pursued from shortly after the halfway point was one of the weakest narrative elements, one which felt gratuitous and overdone. I understand where it came from, and how it aimed to show how grief was leading Book down a dark path. But after everything Captain Burnham went through with Ash Tyler, seeing her settled and happy with Book was fantastic – and I greatly disliked how Discovery ripped that away.
The relationship drama storyline also trod on the toes of other potentially interesting stories. Discovery has always been the Michael Burnham show, and expecting that to change in Season 4 was unrealistic, perhaps. But even so, episodes like All In and Rubicon sidelined other stories and other characters to allow more time to be spent on Book and Burnham and the way they were feeling. For me, it was just too much – and one consequence of that was that some potentially-interesting story arcs, like Dr Culber’s mental health struggles, didn’t get as much development as they deserved.
When Book and Burnham reconciled at the end of Coming Home it really felt great – and I hope that their relationship will remain rock-solid for the remainder of the series’ run!
So that theory was confirmed.
Next, let’s run through the theories that were debunked as of the end of Coming Home.
Debunked theory #1: Unknown Species 10-C is responsible for the galaxy’s dilithium supply running out.
Dilithium aboard the USS Discovery in Season 3.
This is the first of several theories that were connected to the events of Season 3. For whatever reason, though, Discovery’s focus shifted far away from the Burn in Season 4, with only a few mentions of the phenomenon and its consequences. The state of the galaxy in the aftermath of the Burn served as a backdrop to the events of the season, but in many ways the story could’ve unfolded in exactly the same way if the Burn had never happened or if we’d never come to know about it!
In short, I speculated that Unknown Species 10-C may have been mining the galaxy for dilithium in a similar way to how they used the DMA to mine for boronite. If so, perhaps they could have been behind the still-unexplained loss of dilithium supplies in the years leading up to the Burn. As it is, there was no connection – or at least, no connection was apparent as of the end of the season.
Debunked theory #2: The Guardian of Forever will make an appearance.
The Guardian of Forever in The Animated Series.
The Guardian of Forever potentially opened up a completely different story trajectory for Burnham – and for Book and Tarka in particular. The events of Terra Firma in Season 3 seem to confirm that the Guardian can be a portal not only to travel through time but also to cross between universes. With Tarka hoping to cross over to a different parallel universe, the Guardian of Forever seemed like a plausible way for him to do so – potentially allowing everyone to get what they wanted.
As it is, Tarka’s story ended in an unspectacular fashion, and unfortunately I consider his storyline to be a bit of a waste. A fun, exciting, and nuanced character was set up earlier in the season, only to turn into a fairly flaccid and one-dimensional villain as the story reached its end. The Guardian of Forever was never mentioned, and Tarka presumably died when Book’s ship exploded.
Debunked theory #3: Unknown Species 10-C is connected to a faction from Star Trek’s past.
A member of Unknown Species 10-C.
I clung on to my shrinking list of Unknown Species 10-C candidates for the longest time, but I was finally forced to give up on the idea of the mysterious race turning out to be someone familiar a couple of weeks before the season finale! However, even if Unknown Species 10-C were new to Star Trek, I theorised – with very little to back it up, I should say – that there could be some kind of connection to another faction from the franchise’s past.
It couldn’t be the Federation, nor almost any organic race, but it seemed possible to me that there could be a connection to someone like the Borg. If Unknown Species 10-C had been the victim of an attack by someone like the Borg, that could’ve explained their desire to hide away from the rest of the galaxy.
As it is, no connection was forthcoming. I fully expect Unknown Species 10-C to be a minor part of Season 5 (at best), so I doubt we’ll learn much more about them any time soon.
Debunked theory #4: A major character will be killed.
A Starfleet coffin, draped with the flag of the Federation, as seen in Deep Space Nine.
Before the season began I took a look at the main characters and speculated about who may or may not be on the chopping block! As television storytelling has changed and evolved, particularly in the wake of shows with “disposable” casts like The Walking Dead and Game of Thrones, audience expectations have changed as well. I suggested several times throughout the season that Discovery giving its main characters some pretty heavy plot armour in the face of incredibly challenging missions and dangerous circumstances wasn’t a great look – and I kept this theory in play right up until the season’s final moments.
The fake-out over Book’s death wasn’t a problem, and I don’t want to single it out for criticism just because it was the final example of this phenomenon; I felt it worked well in Coming Home. But looking back at the season overall, there were multiple opportunities to kill off characters in meaningful and impactful ways, but Discovery’s writers chose not to. Even minor characters like Dr Pollard and Commander Bryce seem to have survived the season, and while Tarka was killed, as a villain his death doesn’t count in the same way.
A well-timed character death can do so much for a story, and I feel like Discovery dropped the ball on this one during Season 4.
Debunked theory #5: Admiral Vance’s holo-message about Earth and Ni’Var was fake or has been tampered with.
Admiral Vance in Coming Home.
Although Coming Home absolutely stuck the landing and made the sequences at Federation HQ feel incredibly tense and emotional, I didn’t like the whole “Earth is in danger” story cliché that had been introduced in The Galactic Barrier. That trope isn’t just one that’s overused in stories like these, but it’s one that can fall flat and fail in its effort to ramp up the drama, tension, and excitement.
In short, we know in a story about Earth being in danger that Captain Burnham is going to find a way to save the day. If it were literally any other planet – Ni’Var, Qo’noS, Bajor, or wherever – there’d be a real sense of danger that Discovery could’ve repeated the shock of Kwejian’s destruction at the beginning of the season and blown up another planet! But because it was Earth, that never felt like a realistic prospect, and that potentially robbed the story of much of its drama.
I had speculated that someone might’ve faked the message about Earth being in danger, partly because I was hoping it wasn’t true and partly because I was wondering if there might be more going on at Federation HQ. But it turned out that the message was accurate, leading to the scenes at Federation HQ in Coming Home.
Debunked theories #6 & 7: Unknown Species 10-C built the Galactic Barrier, and Someone else built the Galactic Barrier to keep Unknown Species 10-C out.
The USS Discovery at the Galactic Barrier.
As we headed into the season finale, the Galactic Barrier was definitely fading out of sight, and as a result this theory was already feeling less likely. However, after much had been made of the Barrier earlier in the season, with an entire episode dedicated to crossing it, I wondered if we might learn more about this unusual phenomenon!
The Galactic Barrier had been introduced right at the beginning of The Original Series and had been mentioned on several occasions throughout Star Trek’s history. It served an interesting storytelling purpose, but we didn’t really learn much about it – including how it works or why it exists! There was scope to tie the Barrier’s existence to Unknown Species 10-C; their incredible engineering skills suggested that they could be responsible for its construction. Alternatively, I theorised that someone else might’ve constructed it in the past to prevent Unknown Species 10-C from attacking. Neither theory panned out, and it seems very unlikely we’ll revisit the Galactic Barrier next season, so I don’t expect this one to be picked up any time soon.
It would be interesting to learn more about the Galactic Barrier and where it came from, though.
Debunked theory #8: There will be a character crossover from a past iteration of Star Trek.
Geordi and Scotty in Relics.
I’ve been sticking to my guns on this theory since well before Season 3, and a couple of years ago I even proposed a shortlist of characters who could still be alive in the 32nd Century. Thanks to technobabble, though, practically anyone from Star Trek could be included if the writers wanted to bring them on board.
There was also the possibility of Captain Burnham unearthing a hologram, recording, or log left behind by a long-gone character who might be familiar to us as the audience. While this would be less of a “crossover” in the same way, it could still be exceptionally fun.
Unfortunately, it didn’t happen this season. I haven’t given up, though, so you can expect to see this one on my Season 5 theory list!
Debunked theory #9: Book will find Kyheem and Leto inside the hyperfield.
Book with Leto and Kyheem in the season premiere.
One of my first thoughts about the DMA, long before it had a name and before the season had even aired, was that it could be related somehow to the Nexus from Star Trek: Generations. Then later, when we learned that the DMA had wormhole and transporter capabilities, sending material back to its point of origin, it seemed possible that maybe not everyone on Kwejian was as dead as we first assumed.
Just like Captain Picard was able to encounter Captain Kirk inside the Nexus, I wondered if Book might reach the hyperfield only to discover that Leto, Kyheem, and others from Kwejian had survived the destruction of their planet. It didn’t happen in the end, and in a way that’s a good thing because it would’ve undermined the powerful moment Book had when he spoke to Unknown Species 10-C and took them to task for their destruction.
Debunked theory #10: Season 4 will connect with the Short Treks episode Calypso.
Craft and Zora dancing in Calypso.
Is Calypso destined to remain forever out of reach? After Seasons 3 and 4 both seemed to move toward a potential tie-in with the Short Treks outlier, once again the story came to an end with no connection in sight. While things like Zora’s development definitely tie in with the events of Calypso, other things, like the retrofit the ship went through in Season 3, have actually moved us away from the events of that short episode.
This is a tough one. I strongly suspect that Calypso was created at a time when Season 2 had a different ending – perhaps even as a kind of “epilogue” in the event of the whole series being cancelled. Its story of the ship being abandoned for a thousand years and an AI developing sentience from the ship’s computer feel quite far-removed from the stories told in Seasons 3 and 4, and realistically, unless a multi-episode arc can be written to bring Discovery and Calypso together, it may be destined to remain unresolved.
Debunked theory #11: We haven’t seen the last of the Abronians.
Abronian stasis pods.
It’s a bit of a surprise to me that the Abronians – a race rescued from cryo-sleep by Captain Burnham, Tilly, and Dr Gabrielle Burnham in the episode Choose To Live – didn’t return later in the season. There were several different ways that they could’ve been included, even if they didn’t tie in with the main Unknown Species 10-C story.
Discovery doesn’t usually like to do wholly standalone side-stories like this, so all season long I was half-expecting to see the Abronians make a reappearance! Perhaps we’d learn that their homeworld had been destroyed by the DMA, or maybe they could’ve arrived to assist the Federation in an hour of need. Their massive planetoid-sized ship could’ve been incredibly useful during the evacuation of Earth and Ni’Var, for instance.
Debunked theory #12: Tarka will create his own DMA.
Stamets, Tarka, and Saru with the DMA model.
If Tarka had been unable to find the DMA’s power source inside the hyperfield, I wondered if he’d resort to building his own DMA. We saw as far back as The Examples that he understood the basic principles involved and had been able to build a scale model. I speculated that maybe he would go on to build his own version.
This theory originally began when Tarka was on my list of suspects for creating the original DMA. That didn’t pan out, of course, but even going into the season finale it still seemed possible that he might try to build his own version of it.
Debunked theory #13: Kayalise is the Kelvin universe.
The USS Kelvin, namesake of the Kelvin timeline.
In the weeks ahead I’d like to take a look at Ruon Tarka’s story in a bit more detail, as I feel that it started very strongly but went off the rails toward the end. For now, suffice to say that it’s disappointing that we didn’t learn more about Kayalise – the alternate universe that Tarka hoped to travel to.
I speculated that Kayalise could be the Kelvin timeline – it’s one of the only other parallel universes that we know of in Star Trek, it stands to reason that the Burn didn’t happen there, and Discovery had already dropped a Kelvin-timeline reference in Season 3. It could’ve been interesting to follow Tarka across the divide between universes… but it didn’t happen.
Debunked theory #14: Oros is alive – and we’ll see him soon!
Oros.
Oros was a fun and interesting character, and it’s such a shame we only got to see him for a few flashback sequences in a single episode. There was scope to follow more of his story, and if Tarka’s storyline had ended in a more satisfying manner, a meet-up could’ve been on the cards.
I speculated that Tarka would successfully use his interdimensional transporter, or that a compromise could be found to allow him passage to Kayalise, and that he’d be able to reunite with his long-lost friend.
Overall, Oros’ inclusion in the story was an odd one. I feel that we were teased unnecessarily by the show keeping his name hidden for several episodes, and that encouraged speculation that this character might’ve been someone we’re already familiar with. For the heavily-teased character to make a single appearance and then never return was strange – and a bit of a let-down.
Debunked theory #15: The interdimensional transporter works!
Tarka with the interdimensional transporter.
Though it was left somewhat ambiguous as Book’s ship met an explosive end, it seems pretty clear to me that the interdimensional transporter won’t be making a return to Star Trek anytime soon! Tarka held onto hope for the longest time that not only would his own model work, but that Oros’ original interdimensional transporter had as well.
There was scope, had the season ended in a different way, for the interdimensional transporter to be useful for Captain Burnham, too. If Unknown Species 10-C were native to a different dimension, for example, that could’ve been a way to tie the two halves of the story together. In a season that was all about diplomacy, compromise, and finding a middle ground, Captain Burnham could’ve traded with Tarka for the technology, and that’s just one example.
As it is, it seems like we’ll never know whether the interdimensional transporter even worked at all.
Debunked theory #16: Michael Burnham won’t remain in command of the USS Discovery.
Captain Burnham with the President of United Earth at the end of Coming Home.
In short, I speculated that Discovery’s trend of having a different captain for every season might continue, and that the season could end with Captain Burnham either leaving Starfleet to be with Book, or accepting a new role within the organisation. To be clear, because I know there’s a lot of debate any time Captain Burnham is mentioned: I wasn’t in favour of this theory necessarily. I just thought it was a possibility, and a potentially interesting one at that!
In the end, the season drew to a close with Captain Burnham still in command, ready to tackle the next mission as the Federation continues to rebuild. And that was a great way for things to end!
So those theories were debunked!
There are a handful of theories that were connected to events in Season 3 that I also kept on the list this time, and none of those were really touched on at all. In addition, there are a couple of theories that I introduced in Season 4 that I still consider plausible for future seasons or stories. We’ll take a look at those briefly now.
Theory #1: Saru will assume command of the USS Voyager-J.
Captain Saru.
The captaincy of the USS Voyager-J – seemingly the Federation’s new flagship – was discussed as the season drew to a close. President Rillak, who had determined Captain Burnham to be unsuitable for the role in the season premiere, changed her mind after the mission to Unknown Species 10-C’s hyperfield.
I had suggested that Saru embodies many of the qualities that President Rillak was looking for in a captain for the Voyager-J, and that he might assume command of the ship at the end of the season. There’s also the question of how Saru, who holds the rank of captain, will fit in with the command structure aboard the USS Discovery going forward; his presence as Captain Burnham’s XO this season was implied to be temporary.
Whether Saru has a major role to play in Season 5 or not, I’m keeping this one on the list at least for now.
Theory #2: Who is Dr Kovich, and what is his role within the Federation hierarchy?
Dr Kovich.
I’m beginning to feel that Dr Kovich is seen by the show’s writers as a bit of a joke; a character who we’ve been teased with, but whose interesting-sounding lines and suggestions never go anywhere. The most egregious example of this has to be his line in The Galactic Barrier, where he spoke of having “more important things” to do than accompany the USS Discovery. What were those important things? The show never bothered to tell us.
Going all the way back to his first appearance in Season 3, Dr Kovich has been intriguing. Is he a Section 31 operative? The Federation Vice-President? Admiral Vance’s boss? We don’t know, and while Dr Kovich has occupied several different roles this season – counsellor, Starfleet Academy instructor, diplomat, etc. – we still don’t know who he is or what he’s all about.
I’d like to hope we’ll learn more about him in Season 5!
Theories #3 & 4: We’ll learn more about the ban on time travel, and Has the Federation violated the ban on time travel?
La Sirena prepares to use the sun to travel back in time in Star Trek: Picard.
The ban on time travel was introduced in Season 3, and there were narrative reasons for its inclusion. However, as I’ve said ever since we first learned about it: such a ban would be incredibly difficult to implement and enforce. I’d love to know more about how it works, how it’s enforced, and who’s responsible for preventing basically anyone with a starship from doing something like the “slingshot method.”
I also think it’s possible that the Federation itself (or perhaps an organisation like Section 31) has chosen to ignore the ban when it suited them, and again I’d be curious to learn if someone like President Rillak or Dr Kovich had greenlit some kind of time travel escapade.
Theory #5: The USS Discovery will have to defend the Verubin Nebula.
The dilithium planet at the heart of the Verubin Nebula.
The Verubin Nebula is the galaxy’s only major source of dilithium (at least, as of the end of Season 3). With the Federation in control of this incredibly valuable resource, it stands to reason that other, more aggressive powers might seek to take it from them. Even if the Federation is willing to share its bounty with everyone, factions such as the Borg Collective, the Dominion, or the Klingon Empire may not be satisfied and may want to control the Verubin Nebula for themselves.
I speculated prior to Season 4 that the USS Discovery may be called into action to defend the Verubin Nebula from such an attack – and even though it didn’t happen this time, it’s still a possibility for Season 5!
Theory #6: Some areas of the galaxy, such as the Delta Quadrant, avoided the worst effects of the Burn.
Stamets with a map of the galaxy.
The Burn was mentioned in Season 4, but never came to the fore in a major way. We still don’t know how far its impact reached, and what effects the Burn had on far-flung parts of the galaxy far away from the Verubin Nebula.
I speculated that some regions of the galaxy may have avoided the worst of the Burn, and maybe some areas didn’t even feel it at all. It could be very interesting to learn that a faction such as the Borg – who were mentioned in Discovery for the first time near the end of Season 4 – were unaffected. They might’ve been able to spend the last hundred years building up their forces for a major invasion!
Finally, we had three production-side theories on the list as the season finale approached, and I’d like to take a look at those before we wrap things up.
Production-side theory #1: The season will end on a cliffhanger.
This one is officially debunked! As the finale got closer and closer with seemingly a lot of different narrative threads still in play, I wondered if the season might’ve ended on a cliffhanger, with the story to be resumed in Season 5. It didn’t happen, though, and while not every storyline was brought to the perfect ending from my point of view, all of the main narrative threads were tied up by the time the credits rolled.
Star Trek has a history of season-ending cliffhangers, so this didn’t feel too far-fetched! Still, it will be nice to have a clean slate going into Season 5.
Production-side theory #2: Tilly’s departure will be permanent.
Tilly’s departure.
This is still officially unconfirmed at time of writing. We don’t yet know whether Mary Wiseman will be returning in Season 5, and if she does return, whether she’ll be doing so as a main cast member or just making a cameo or guest appearance.
It was nice to have Tilly back for the scenes at Federation HQ in Coming Home, and I’m glad we got to spend a little more time with her. However, to me her decision in All Is Possible felt permanent, and taking up a new role at Starfleet Academy feels like a good fit for her. Undoing that development, and unravelling that interesting and fitting character arc, wouldn’t be my preference.
There’s also the possibility that the rumoured Starfleet Academy series could bring back Tilly in a major role. Either way, we’ll have to wait and see!
Production-side theory #3: There will be a crossover of some kind with Picard Season 2.
Admiral Picard.
As you’ll know by now if you’ve watched both shows, no crossover between Picard and Discovery was forthcoming. This theory arose because Picard Season 2 and Discovery Season 4 overlapped one another by three weeks – something that I genuinely cannot explain. Paramount Global consistently makes these random, illogical decisions, and while it was fun to speculate about what a Picard-Discovery crossover could look like… now that the dust has settled I genuinely do not understand why it had to happen this way. Is it something to do with the fiscal year?
Given that Paramount+ remains unavailable in most of the world, and that Strange New Worlds’ premiere is now imminent, the scheduling makes even less sense. Delaying Picard’s second season by a measly three weeks would’ve bought a little more time for Paramount+ to be ready. Three weeks may not have made all the difference, but combine it with a short delay to Strange New Worlds and maybe it would’ve been possible for more Trekkies to watch the new series together.
I’m not disappointed that a crossover didn’t happen – though that could’ve been a lot of fun. But I am disappointed in Paramount and the inept way they’re handling the Star Trek franchise.
So that’s it!
A happy ending!
Thank you for sticking with me through Star Trek: Discovery Season 4. As the season wore on I did get some things right with my theories, even if some of my bigger ones – like the identity of Unknown Species 10-C – were wide of the mark.
Discovery Season 4 began in a truly awful corporate mess, with Paramount paying money out of its own pocket to try to take the show away from fans outside of the United States. Even in regions where Paramount+ was available, they originally planned to deny viewers access to Discovery Season 4. While I’m glad that the corporation recognised the backlash from fans and backtracked on those plans, it’s something I haven’t forgotten. With Strange New Worldsnow in the same position, it’s clear to me that Paramount Global has learned nothing.
Federation HQ in orbit of Earth; the final shot of the season.
In the weeks ahead I’ll definitely write up a longer retrospective of the season. For now, suffice to say that it was a mixed bag, with some decent episodes and some that dragged. The main storyline – that of the DMA and Unknown Species 10-C – seemed to take a long time to reach its conclusion, feeling padded in places. However, the season finale brought things to a close in a very emotional, entertaining, and enjoyable way. Whatever I may have thought about parts of the ride, the destination in this case was worth the wait.
One final note. I write up these theories for fun! I like Star Trek and I like writing, so writing about Star Trek is an enjoyable endeavour for me. For some folks, though, fan theories can become problematic. It’s always worth trying to keep in mind that any fan theory, no matter how enjoyable and plausible it may seem, isn’t worth getting upset over. Most of the theories I come up with never make it to screen, and usually what unfolds on screen is better! If I ever found that theorising and speculating about Star Trek (or any other franchise) was beginning to harm my enjoyment, I’d stop – and I’d encourage anyone in that position to do the same.
Star Trek: Discovery Season 4 is available to stream now on Paramount+ in the United States, Scandinavia, Latin America, and Australia. The show is available on Pluto TV in the UK, France, Germany, Italy, and other parts of Western Europe. Individual episodes or the full season can be purchased on iTunes, Amazon Video, Google Play, and possibly other platforms in the UK, parts of Europe, and select other countries.

Spoiler Warning: There are spoilers ahead for Star Trek: Discovery Seasons 1-4.
I cried a lot while watching Coming Home. It was an incredibly emotional episode, one that hit all of the notes that it was aiming for and brought the season to a close in style. We can say definitively that Season 4 ended on a high, having saved the best for last. In fact, Coming Home might just be the best episode of the entire season!
From almost the first minute, the emotional punches started coming – and they didn’t let up until the epilogue. Captain Burnham and the entire crew went on a rollercoaster ride as they battled to stop Tarka, to get Unknown Species 10-C to listen, and to save Earth and Ni’Var from destruction. The episode was well-paced, with plenty of energy to keep things exciting but without ever feeling rushed. And there were some wonderful visual effects and animation work as we finally got an unobscured look at Unknown Species 10-C.
A group of Unknown Species 10-C.
I had a wonderful time with Coming Home, and thinking about Season 4 as a whole, the finale is one of the strongest offerings. That contrasts with Season 3, where the end of the Burn’s story felt like a non-sequitur, if not an outright letdown. In that respect, it’s nice to see that Discovery has grown, adapted, and perhaps even taken on board some of the feedback received about the Burn and Season 3 in general. The creative team can be pleased, I think, that they did a better job this time around.
All that being said, there are some issues that are raised by Coming Home. The episode itself was great, and even some of the storylines that I’d been less invested in were paid off in emotional style. But thinking about the episode as the concluding chapter of a thirteen-episode season, I do have some complaints about absences, about characters who weren’t well-used, and about specific storylines that didn’t get the kind of payoff I’d been hoping for. While these points don’t detract from a wonderful and emotional episode in Coming Home, they do count against Season 4 as a whole.
Dr Hirai was a character with potential who felt sadly underused this season.
In the weeks ahead I’d like to do a retrospective of the season, and when I do I’ll go into more detail about some of these complaints. But with Coming Home being the season finale, I’d be remiss not to mention them here. This was the last chance for Discovery to do something significant with some of these narrative points – especially when considering that Season 5 will almost certainly go in a different direction.
Ruon Tarka’s abrupt turnaround from an understandable and even sympathetic character to a bold-faced villain was not handled particularly well, and while Coming Home went some way toward reversing that and bringing back some of the nuance that had made him such an interesting character in the first place, it came too late. Tarka’s story – much like Tarka himself in his final moments – ran out of road, and ended in an unspectacular and unsatisfying fashion, with no real payoff to his quest to reach Oros and Kayalise.
Tarka met his end in an unsatisfying way.
The scenes between Tarka and Book were beautifully constructed, and the raw emotion that both David Ajala and Shawn Doyle brought to screen is undeniable. The performances were fantastic, and Coming Home found enough time to show off these moments despite having plenty of other narrative beats to get through.
Despite that, however, the damage to Tarka’s characterisation had already been done. The complex and nuanced character that we met in The Examples, half a season ago, had been developed slowly over several episodes. His desire to use the power source at the heart of the DMA was explained through a series of flashbacks that introduced us to his long-lost friend Oros… and it feels like none of that really went anywhere. There were the ongoing themes of grief and loss that have been running since Season 3, and I guess we could argue that Tarka represents a different kind of reaction to those things than other characters. But even then, this side of the story doesn’t feel particularly strong.

It was nice to see that, in his final moments, Tarka seemed to come around to Book’s way of thinking. As he stood on the wrecked bridge of Book’s ship, awaiting the inevitable, he’d taken several steps back toward being the complex character that we believed him to be in his earlier appearances, and I do appreciate that. It wasn’t that there wasn’t time to pay off Tarka’s well-established story. It’s just that Discovery chose not to.
This was a story that, at the end of the day, didn’t need Tarka. It didn’t need a villain to be outsmarted and killed in the final act; all the pieces were in place for a story of first contact with Unknown Species 10-C that was tense, interesting, and engaging without him. There was more than enough drama and excitement in that premise to make Tarka’s addition unnecessary; fluff to pad out a season-long story that I’m sure I’m not alone in feeling had been padded out far more than it should’ve been.
Tarka was ultimately the villain of the season… but he didn’t need to be.
Season 4 could have been structured differently, with the Tarka and Unknown Species 10-C stories going in different directions. If one story had concluded around the time of the mid-season break, the second half of the season could’ve followed another related but separate story… and when both sides of the story were overstretched by running for as many episodes as they did, perhaps that would’ve been preferable.
But that’s less about Coming Home than it is about the structure of the season as a whole! Despite my waning interest in the Book and Tarka story, Coming Home pulled out a complex and emotional ending for both characters. It wasn’t the way I would’ve necessarily hoped for nor chosen, but once the decision had been made to kill off Tarka in this way and to have the fake-out over Book’s death, Discovery executed it about as well as possible.
Tarka and Book caught in an explosion.
Going into the finale there were genuine concerns for Book and Reno’s survival. While a fifth season has been confirmed, neither character was guaranteed to appear in it, and there was a real possibility that one or both could’ve died as Tarka tried to execute an increasingly desperate (and, sadly, an increasingly nonsensical) plan. When it came to the moment of Book’s apparent death, it thus felt like he was really gone; there was no part of me saying “this is all just a fake-out.” And again, this was one of many emotional punches that Coming Home set up and delivered perfectly.
Book’s survival was also kept hidden by the story – we weren’t immediately shown him alive with Unknown Species 10-C – which kept things going as other storylines played out. As a fake-out, I think it worked pretty well. It made Book’s return in a pillar of light feel genuinely wonderful, and took Captain Burnham on a rollercoaster that allowed Sonequa Martin-Green to really show off her emotional range. Both as a story point and on the technical side of things, it worked well for Coming Home.
Book was saved by Unknown Species 10-C.
But, as I’ve found myself saying numerous times as the season has worn on, it means that Discovery has yet again given all of its characters some pretty serious plot armour. In an individual episode we can forgive that a near-death situation resulted in survival, or that an apparently-dead character like Book was safe all along. But when we consider the season overall, no one aside from Tarka was actually killed. Despite the incredibly dangerous situations that the crew found themselves in, and despite the overwhelming odds stacked against them by Unknown Species 10-C, the DMA, Tarka, and everything else they went through, they all survived.
Television storytelling has moved on since Star Trek’s early days – something that the very nature of Discovery is itself testament to. To run an entire season this way – with another “galaxy-ending” calamity for the crew to deal with, which they all survive – risks diminishing the threat felt in future stories. If we as the audience can feel confident that everyone will be fine, no matter what else is happening or how badly the ship seems to be blowing up, that robs the show of a significant portion of the excitement, tension, and drama that its storylines have done an otherwise good job at creating. Book’s fake-out “death” isn’t the problem in and of itself; it’s a symptom of a much bigger issue – the obvious lack of willingness on the part of Discovery’s writers to allow even the most minor of tertiary characters to be killed off. In 2022 that’s out-of-date, and it’s a storytelling mistake that will have to be addressed in future.
Book survived… and so did everyone else.
The whole “Earth is in danger” angle is a trope that I wish hadn’t been brought into the story this season. It’s such a played-out cliché, and it’s one which, as I noted a couple of episodes ago when it was introduced, risks making the end of the story feel formulaic. It was obvious two episodes back that Discovery wasn’t going to allow the destruction of Earth and Ni’Var in the final act of Season 4, so unfortunately I went into Coming Home with that expectation firmly embedded in my mind.
That doesn’t mean that the route to saving Earth was easy, and on the Federation HQ side of the story with Tilly and Admiral Vance there were some absolutely wonderful moments. The swooping arrival of the USS Mitchell – named for Discovery actor Kenneth Mitchell – hit all of the right notes for me, echoing moments like the Enterprise-E’s dramatic entrance during the Battle of Sector 001 in First Contact. In fact, all of the evacuation sequences worked well, and after her departure earlier in the season it was nice to welcome back Tilly – however briefly.
The USS Mitchell arrived to save the day!
I’d have liked to have seen something earlier in the season to perhaps set up some kind of dynamic between Vance and Tilly, and that would really be my only criticism. The two didn’t feel like they had natural chemistry; I was acutely aware of the difference in status between the head of Starfleet and a character who, until a few episodes ago, was a lowly ensign. The two performers did well to sell it, but had we seen Tilly offered her role at Starfleet Academy by Vance, not Kovich, back in All Is Possible, I think we would’ve had some kind of baseline for their relationship. This would’ve let us see how far they’d come to be able to sit together and share a drink as they awaited what seemed to be the inevitable.
That said, I liked the evacuation sequences. In fact, this part of Coming Home might actually be my favourite – surpassing the meeting with Unknown Species 10-C, and definitely beating out the conclusion to Tarka’s story. There’s something about a doomed, heroic “last stand” that always gets me no matter how it’s played, and for Vance and Tilly, they knew that they didn’t have any control over the DMA situation. They had to do their jobs knowing there was nothing they could do to prevent what was happening – they were relying entirely on Captain Burnham and the USS Discovery.
Admiral Vance led the evacuation efforts.
That setup led to a real unexpected highlight. I maintain it would still have worked were it not Earth in the firing line, but setting aside that particular narrative gripe, the scenes at Federation Headquarters were pitch-perfect. Seeing Federation HQ warp in to offer to help, even though Earth was not a member of the Federation, really epitomises what the Federation is all about. That is the spirit of Star Trek, in many ways: offering to help while asking nothing in return. The DMA placed Earth in danger, and Starfleet rode in to help without even having to think twice.
Admiral Vance and Tilly both came to embody that Federation spirit in these sequences, and they gave it their all to get as many people to safety as they possibly could. Choosing to remain behind to cover the escape of the final ships was just the perfect end for both of them – and something I could absolutely see both of them being willing to do. As they sat down, knowing they’d given their all, and shared a drink, I was absolutely blown away by this unexpected and wonderful addition to Coming Home.

We also got to spend a little more time with some of Tilly’s cadets from All Is Possible. After those characters fell somewhat flat in that story, it seems like at least some of them have grown into their roles as Starfleet cadets, which was nice to see. It wasn’t a huge part of this side of the story, but it was a neat way to include something that had been established earlier in the season.
There was, unfortunately, a gaping hole on this side of the story. It wasn’t really apparent until Coming Home was drawing to a close, and it didn’t detract from the way any of these incredibly emotional moments felt as they unfolded. But in retrospect I have to ask: where was Dr Kovich? Is he just a gag character now, someone whose lines tease stories that sound interesting but go nowhere? Because that’s what it feels like. After Dr Kovich’s line in The Galactic Barrier that he had “more important things” to do than make first contact with the species who built the DMA, I was hoping that Discovery would pay that off somehow… but it didn’t happen.
What happened to Dr Kovich?
We’ll deal more with the Dr Kovich situation when I take a look back at the season as a whole, but suffice to say that his absence from this part of the story was noticeable, and several threads that seemed to tease that he was working on something interesting with Lieutenant Commander Bryce ultimately just went nowhere. This isn’t a situation like the Picard Season 1 finale, either, where the meandering story of the season ran out of road and didn’t have enough time to pay off its stories… this was a conscious choice on the part of Discovery’s writers. They teased us with Dr Kovich all season long, feeding us little crumbs of information that seemed to set up something about his character… and then just dropped it, perhaps with a snide laugh behind their hands, in the finale.
As the episode wrapped up, it seemed as though Discovery had one last surprise up its sleeve. As the President of United Earth was about to arrive, I wondered if we might be about to see Dr Kovich when the doors wooshed open – if not, perhaps a character from a past iteration of the series. When it was revealed to be a new character I wasn’t disappointed; it seemed as if the point the series was making with the buildup to her reveal was that the President of the Federation, the President of United Earth, and the Captain of Discovery are all women, which I thought was a neat way to go.
I had no idea who this was at first!
But there was more to it that, as a non-American, I missed at first! The President of United Earth was played by Stacey Abrams, an American politician and writer who’s been quite politically active on the left wing of US politics. This casting choice is interesting – and perhaps a little provocative! There will be people on the conservative side of things who will feel upset, and Discovery knew this well in advance of casting this character. Doing so was a way for the series to really emphasise its progressive principles, which have been front-and-centre just as they’ve always been in Star Trek.
Star Trek is no stranger to cameos and stunt castings, before anyone jumps in to say that this one is somehow different because of who it is. The King of Jordan had a cameo in Voyager once upon a time, and there have been real-life astronauts, scientists, and other celebrities who’ve all joined in for guest-starring roles. Considering that Stacey Abrams is, as far as I’m aware anyway, a newbie to acting, I think she did a wonderful job!
The President and the President shake hands.
I adored this scene with the President of United Earth. Set aside the casting for a moment, because the content of the scene made a huge impact on me. Coming Home had already been a hugely emotional story, so seeing Earth rejoin the Federation after two seasons outside it was pitch-perfect. Stacey Abrams and Sonequa Martin-Green excelled in their moments together, and what resulted was an optimistic and emotional high to bring the episode – and the season – to a conclusion.
There are some interesting real-world parallels that the casting of someone like Stacey Abrams arguably hammers home. After the United States had pursued a nativist, isolationist policy for four years, the country is stepping away from that. United Earth rejoining the Federation could be viewed as symbolic of America’s return to the world stage. From a British perspective, it could be seen as a hope for the UK one day rejoining the European Union after the Brexit referendum. Star Trek has always used its sci-fi setting to look at real-world issues, and those are just a couple of possible ways we can interpret this emotional and uplifting end to the season.

We’ve come all this way but we still haven’t talked about Unknown Species 10-C! The visual effects used to create one of the most “alien” races ever seen on screen in Star Trek were excellent, though I would caveat that by saying that the meeting place being a carbon copy of the ruin visited in Rosetta detracted a little from the way things looked. Recycling sets has been something that the Star Trek franchise has always done, but this moment was the crux of a season-long story, and I think more could’ve been done to give Unknown Species 10-C’s new home a new look, even if it was just in a minor way through changes and tweaks. It’s been a millennium since they lived on the planet seen in Rosetta, so if for no other reason than the passage of time we might’ve expected it to look slightly different.
That being said, I liked Unknown Species 10-C both in appearance and in concept. Star Trek has a long history of showing us alien races that look only slightly different to humans – and in some cases are completely identical! That’s never been a problem for me; I think it’s part of the suspension of disbelief that one has to have when stepping into the Star Trek galaxy. However, the rise of modern CGI and animation, combined with new technologies like Discovery’s AR wall, mean that some very different aliens can be created and can be blended with real actors. This blend was seamless in Coming Home – as it has been, with only a few exceptions, all season long.

The story of bridging a communication divide is honestly one that I could’ve spent longer on. Much of the legwork had been done in Species Ten-Clast week, so we got less of the minutiae that a “learning to understand one another” story can provide. But what we did get was interesting, and we got to see how Unknown Species 10-C didn’t mean to do anything wrong – their scans didn’t indicate that there were sentient life-forms in the areas that the DMA hit.
In that sense, we have a comparable situation to the Burn in Season 3. Unknown Species 10-C weren’t some horrible invading alien for Starfleet to heroically defeat; what happened was a genuine accident, one that they regret. That may not be enough for someone like Book, who lost his home, his family, and his entire race… but it’s a different ending, one that many other sci-fi franchises wouldn’t have even considered. Discovery pulled it off, and while the story leading up to it was imperfect and padded, it worked.
A representative of Unknown Species 10-C conveys their regret to the assembled crew and delegates.
However, Discovery has now run four seasons with some variation of the “major galactic threat” storyline, and I think that framework needs a break. Not every story has to be about the entire galaxy, Earth, and the whole Federation being in danger – there can be just as much drama, tension, excitement, and emotion from stories that are smaller in scale. Just because a story doesn’t threaten life as we know it doesn’t mean it doesn’t matter, and how we as the audience respond to a story begins with the way the characters we’re invested in respond to it. So consider this a plea to all of Discovery’s writers and producers: try something different in Season 5!
I enjoyed the performance from Chelah Horsdal as President Rillak. For practically the whole season I couldn’t tell if we were going to get a “bad Admiral” type of character turn; President Rillak certainly seemed to have a Machiavellian edge that could have made for a wonderfully complex antagonist. In Coming Home, though, we got to see the culmination of her diplomatic efforts and her leadership of the Federation, both through the way the DMA threat came to an end and through Earth rejoining the organisation – something that had been one of her major objectives.

For what feels like the first time this season, Stamets had more than just a couple of lines. It was a shame that he couldn’t be present at the meeting with Unknown Species 10-C; I’d have rather seen him there with Dr Culber and Adira to stand alongside Captain Burnham than some of the secondary bridge characters, really. But it was still nice to see Stamets and his family coming together at the climax of the story, and how Dr Culber forfeited his own chance to go on the away mission to be with them.
Stamets and Culber formed Discovery’s emotional core in the first season and the third, with a disappointing foray into a relationship squabble in the second. But aside from a few smaller scenes, neither character really seemed to have all that much to do in Season 4. With Gray’s story brought to a conclusion early on, in the episode Choose To Live, the family dynamic changed, but Stamets missed practically all of that. In fact, his only scene with Gray all season that I can recall was when Gray left to return to Trill. In short, I was glad to welcome back Stamets in Coming Home, and thrilled to see him bonding again with Culber and Adira… but the reason why it felt so great is because I’m aware of how absent moments like that had been all season long.
Adira, Dr Culber, and Stamets.
I was not a big fan of the Burnham-versus-Book relationship drama angle that began in But To Connect earlier in the season. It didn’t work for me, and I felt that the focus on Burnham and Book’s emotions, particularly in episodes like All In and Rubicon, came at the expense of other characters and other story developments. It was cathartic, then, to see the two finally reconcile in Coming Home, and I’m glad that the season didn’t end with their relationship left in question.
Because of the timing of Book’s fake-out “death,” it could have ended there and still felt satisfactory; Captain Burnham would’ve known that Book loved her, and his actions in his final moments would’ve been trying to stop Tarka and prevent an escalation of the damage he’d already done. That could’ve worked – but I’m glad that Book lives to fight another day and that they got to have a proper sit-down together and a proper reunion on Unknown Species 10-C’s planet. After a storyline that shook things up too much for my taste, a proper resolution that has hopefully set the stage for a rock-solid relationship between them in Season 5 was the least bad outcome.
Captain Burnham and Book embrace.
I enjoyed the speeches both Captain Burnham and Book gave to Unknown Species 10-C, and it was great that they were able to find a way to connect with a species that could have been “too different” to bridge the divide. Book’s speech after his resurrection was remarkable, and the emotion packed into each and every word resonated. David Ajala has done a great job all season long conveying Book’s grief and sense of loss, and he brought everything to bear in this scene as he came face-to-face with the race who killed his family and destroyed his home. It was heart-wrenching to watch.
Captain Burnham’s speech was likewise packed with emotion, particularly as she was still reeling from the shock of Book’s apparent death. This was definitely one of Sonequa Martin-Green’s best moments of the season, as Captain Burnham finally made contact with the enigmatic race. She had to convince them that they needed to stand down – and with just moments remaining, she was able to do so.
Captain Burnham spoke to Unknown Species 10-C.
General Ndoye, who had been responsible for Tarka’s escape during the events of the previous episode, stepped up and admitted what she had done. She presented a strength of character that I wasn’t expecting given how she’d been roped into Tarka and Book’s conspiracy. The idea that the first contact mission was progressing but was sabotaged by people who were unwilling to wait was an angle that was potentially interesting – but it didn’t need to go to such extremes, perhaps.
Still, I liked General Ndoye. Phumzile Sitole played the character with a kind of hard-nosed pragmatism, and although General Ndoye was in the wrong from Captain Burnham’s point of view, it’s only because we as the audience could see what was happening that we realised that. Ndoye acted in what she believed to be Earth’s best interests based on the information she had available – she was never a villain nor an antagonist, and she remained in that complex space even while Tarka was being transformed into an out-and-out villain last week.
General Ndoye.
A few scattered thoughts before we wrap things up:
Coming Home contained the first mention of the Borg in Discovery… could that be setting up something to come in Season 5, or perhaps some kind of tie-in with Picard? I can’t help but wonder! Seeing Captain Burnham go toe-to-toe with the Borg would be delicious!
Dr Hirai felt sidelined once again, contributing relatively little to the story. This character feels like a waste of potential – someone interesting whose role on the mission made sense, but who was underused and who underwhelmed in the few appearances he made.
The destruction of Book’s ship feels like it could be symbolic… but I’m struggling to find the intended symbolism considering that Discovery will presumably bring him back in Season 5, and the show didn’t exactly go through a soft reboot at the end of the season.
Unknown Species 10-C definitely gave me a “sea monster” vibe.
It was so sweet that Saru and T’Rina finally got together!
A happy ending for T’Rina and Saru!
Shutting down the hyperfield, which Unknown Species 10-C had been running for a millennium, seemed a bit quick right at the end.
It would’ve been interesting to see Captain Burnham having to lead Discovery on a Voyager-esque mission back to Earth… but Unknown Species 10-C’s wormhole tech meant it never felt like a realistic prospect.
I will always love seeing Admiral Vance with his family!
The use of Grudge’s collar to escape the forcefield was a clever inclusion that felt like classic Star Trek technobabble.
I hope we’ll see Unknown Species 10-C again and they won’t just be forgotten about in future 32nd Century stories.
Will Federation HQ now remain permanently in orbit of Earth? Or will other planets want to have Federation facilities, given that Earth has been absent for more than a century? It could be interesting to explore such a conflict in Season 5.
Federation HQ in orbit over Earth.
There’s a lot more to say, quite honestly… but I feel this is already running long. It’s taken me a long time – longer than usual – to get my thoughts in order, and I find that a lot of what I want to say in a more critical way is more about the story or structure of the season as a whole rather than about Coming Home specifically. It was a great episode in its own right, it capped off the season in a beautiful, emotional way, and left me with a real sense of optimism as Discovery prepares for a fifth season. But despite a solid ending, Season 4 as a whole is much more of a mixed bag, and I’d like to talk about that more on another occasion.
Coming Home was the emotional high point of an occasionally frustrating season, but it’s an episode that means we can say that things ended on a positive note. I’m genuinely excited for Season 5 and to see where the show goes next… but I hope it’s not going to be another “the galaxy is in danger” storyline! After the Klingon war, Control, the Burn, and the DMA, we’ve had enough of those.
It took me a while to get this review together, partly because of how much of an emotional experience Coming Home was… and partly because I’m feeling a little burnt out after three weeks of two Star Trek episodes meaning I was writing two big reviews! I really wish Paramount Global would sort out its scheduling…
Star Trek: Discovery Season 4 is available to stream now on Paramount+ in the United States, Scandinavia, Latin America, and Australia. Individual episodes or the full season can be purchased on iTunes, Amazon Video, Google Play, and possibly other platforms in the UK, parts of Europe, and select other countries.

Spoiler Warning: There are spoilers ahead for Star Trek: Discovery Seasons 1-4. Spoilers are also present for the following Star Trek productions: Picard Season 2, Voyager, Enterprise, and The Next Generation.
Species Ten-C was a good episode, and while there’s still a lot of story to get through if the season is going to wrap up everything by next week, we’re well on the way to stopping the DMA and saving Earth. This week saw the first major theory cull of the season, with a whopping nine debunked theories. As the season approaches its end, this was to be expected!
We’ve got a lot to get through this time as we whittle down the theory list going into the season finale, so let’s get started by looking at the theories that have been debunked.
Debunked theory #1: Unknown Species 10-C is a faction from a past iteration of Star Trek.
A member of Unknown Species 10-C.
We’d been moving away from this theory for weeks, and it had been looking increasingly unlikely as Captain Burnham and the crew approached their base of operations. As I said when I first considered the theory, it always felt like there was a good chance that Discovery would go down this route; it happened in Season 2 with Control and the Red Angel, and in Season 3 with the Burn. Tarka’s friend Oros also being a new character was a strong indication that Discovery wants to do its own thing, adding to the lore of Star Trek and expanding the franchise instead of returning to elements and factions from the past.
Still, it was fun to consider the different factions that might’ve been involved! There were some genuinely plausible candidates for creating something on the scale of the DMA – the Borg, the Kelvan Empire, and Enterprise’s Sphere-Builders, to name just three – and I had fun putting together my long list earlier in the season. Thinking about where some of these factions could be by the 32nd Century was also interesting.
At the end of the day, I’m not surprised that Discovery went in this direction. What I would say, though, is that now Unknown Species 10-C has been created, I hope Discovery doesn’t just ignore them in Season 5. The story took a long and winding route to reach this point, and it would be a shame if all we ever see of Unknown Species 10-C comes in two episodes at the end of the current season.
Debunked theory #2: Unknown Species 10-C is extinct.
A bone of Unknown Species 10-C.
This theory would have scrapped the “figuring out how to communicate” angle that was a big part of this week’s episode, and would have replaced it with Captain Burnham and the crew perhaps having to discover how to use some very alien technology to shut down the DMA. When we learned more about Unknown Species 10-C, like their planet having suffered a catastrophe, I felt it was plausible that they were no longer around, with the DMA being a kind of Doomsday Machine-inspired device. There could have been interesting allegories for things like climate change and pollution from such a storyline.
Ultimately, of course, Discovery showed us that Unknown Species 10-C is alive and well, living their best life on three planets inside of their hyperfield. As the season enters its final act, I hope we get to learn much more about this unique civilisation.
Debunked theory #3: The bones from Rosetta don’t belong to Unknown Species 10-C.
The away team.
I speculated that the huge bones that the away team found in Rosetta may not actually be from Unknown Species 10-C themselves, and could be from domesticated animals or other creatures that lived on their homeworld. This would have potentially allowed for Unknown Species 10-C to surprise us with their appearance, possibly even being humanoid!
It didn’t turn out that way, though, and although the Unknown Species 10-C representative in Species Ten-C was partially obscured when they made contact with the USS Discovery, they seemed to be the right size and shape for the bones from Rosetta. Also, they used the pheromones that the away team discovered.
Debunked theory #4: The hyperfield will be empty or abandoned.
The USS Discovery at the hyperfield.
This theory could have been connected to the one above, with Unknown Species 10-C being extinct. Or it could have stood on its own, with the hyperfield perhaps serving as a portal or wormhole to a different galaxy or even another dimension. Figuring out where Unknown Species 10-C had gone could have been part of such a story, and maybe Captain Burnham and the crew would have had to leap into the unknown in order to stop the DMA.
As it turned out, the hyperfield had three whole planets inside of it! There were presumably huge numbers of Unknown Species 10-C doing their thing, living their lives and making the hyperfield a thoroughly inhabited place!
Debunked theories #5-8: Someone else made the DMA.
The DMA on Discovery’s viewscreen.
As of last week, I still had the Red Angel suits from Season 2, Oros, Dr Kovich, and President Rillak on my list of possible culprits, either being directly implicated with the DMA or at least being connected to it in some way. I think we can now strike all of them from the list!
Unknown Species 10-C have clearly never met a human, nor anyone else from within the Milky Way galaxy, as we saw from their inquisitiveness and their initial inability to recognise that the strange creatures they’d encountered were even sentient. If they’d discovered a Red Angel suit or met someone like President Rillak or Oros, Discovery’s initial first contact wouldn’t have unfolded in that way.
Finally, with Tarka now being set up as the villain of the season’s final act, there’s no way to add someone like Dr Kovich or President Rillak into the mix as well. Rillak, despite her Machiavellian qualities, now seems to be firmly established on this side of the story. I think there’s scope to spend more time with her, and perhaps even set up an antagonistic role for her in future, but it now seems certain that it won’t happen this season.
Debunked theory #9: Captain Burnham will use the interdimensional transporter.
Burnham using a transporter in Season 1.
It’s still possible that Tarka will get his interdimensional transporter working – even if doing so comes at the expense of hurting Unknown Species 10-C. However, this theory was set up on the premise that Unknown Species 10-C may be from another dimension themselves, and that using Tarka’s device could be the only way to reach them. That is clearly not the case, so I think we can strike it from the list.
I’d like to see the Tarka-Oros storyline about their interdimensional transporter paid off before the season ends… somehow. It would feel a little hollow if all it turns out to be is a macguffin, something to motivate Tarka to pursue this increasingly unhinged plot to steal Unknown Species 10-C’s power-generating tech. But with only one episode remaining, there’s very little time left to do anything meaningful with this side of the story!
So those theories were debunked!
There are several other theories that are hanging by the thinnest of threads, but I’m going to leave them in place for now. Even if they don’t pan out this season, there’s still scope for some of them to be incorporated into Season 5.
We have a number of theories that are still firmly in play, though, so let’s jump into the list!
Theory #1: Unknown Species 10-C is connected to a faction from Star Trek’s past.
The super-synths from Picard Season 1.
Although Unknown Species 10-C turned out to be brand-new to the franchise, there’s still scope for them to have some kind of connection with a faction from Star Trek’s past. Most organic factions are probably ruled out thanks to the way Unknown Species 10-C reacted; they’ve clearly never encountered humans, Kelpiens, or Vulcans before! But they could have met someone like the Borg, for example, or the super-synths from Picard Season 1.
This theory is definitely running out of road with only one episode remaining, and if the season finale has to deal with Tarka and the DMA, perhaps we won’t actually get to learn very much at all about Unknown Species 10-C. However, I think a connection remains a possibility – even if it’s a shrinking one!
Theory #2: Unknown Species 10-C is responsible for the galaxy’s dilithium supply running out.
The KSF Khi’eth was one of many Federation ships scouting for dilithium as supplies dwindled.
It seems as though Unknown Species 10-C may not have been aware that the Milky Way is inhabited by sentient beings. If that’s the case, and they’ve somehow managed to be entirely unaware of everyone from the Andorians and Borg to the Xindi and Yridians, it’s possible that they’ve been exploiting the galaxy for resources for a very long time. Season 3 didn’t explain why dilithium was suddenly in short supply, so it could turn out that Unknown Species 10-C stripped away much of the galaxy’s supply in the years before the Burn.
Unknown Species 10-C could have even used a similar mining tool to the DMA to extract dilithium, sending it back to their hyperfield through wormholes. Again, time seems to be running out to explore this idea in much detail – but it would be a fun and interesting way to link the two 32nd Century seasons together!
Theory #3: Book and Burnham will reconcile and get back together.
Burnham and Book earlier in the season.
Book is in serious danger right now! Trapped aboard his ship with Tarka in control, it’s possible that he won’t survive the season. However, if he does survive I’d very much like to see him and Burnham get back together. The whole “relationship drama” angle was not Season 4’s best narrative choice, and there were other ways to get the main story arcs to this point without disrupting Book and Burnham’s relationship.
However, as of Species Ten-C, Book appears to have moved much closer to Burnham’s position of making peaceful first contact. Partly, it has to be said, this is out of necessity: Tarka’s plan would seemingly destroy the hyperfield, the USS Discovery, Unknown Species 10-C, and would still leave Earth and Ni’Var in danger. But even before the consequences of Tarka’s plan became apparent, Book had moved back in this direction. In Rubicon, we saw how he was willing to pause his plan and wait for diplomacy, so there’s scope for him to fully come back into the fold and reconcile with Burnham.
Though I don’t believe female characters in any way need to have a male character in their life, after Burnham had been on a rollercoaster with Ash Tyler in Season 2, giving her a settled relationship worked very well. It was a shame Discovery went down this road in the first place, but all the pieces seem to be in place for a satisfactory conclusion.
Theory #4: Oros is alive – and we’ll see him soon!
Oros.
The revelation that Tarka’s plan will actually end up killing everyone is a bit of a damp squib; an unnecessary twist that took the character from complex and understandable to out-and-out villain. However, because of the nuanced and interesting characterisation over the preceding few episodes, part of me is still rooting for some kind of reunion between Tarka and the long-lost Oros.
Perhaps Discovery will surprise us by showing Tarka’s plan succeed – he could activate his interdimensional transporter and disappear, leaving Captain Burnham to pick up the pieces. Or maybe a series that has talked big on middle grounds, compromises, and diplomacy will see Captain Burnham or President Rillak reach out to Tarka, offering him a different pathway to success.
Discovery teased us unnecessarily by keeping Oros’ identity a secret before showing us the character in quite a bit of depth. It would be a shame if Oros only exists in flashbacks; less a character than a narrative device to give Tarka’s quest a motivating factor.
Theory #5: The interdimensional transporter works!
Oros and Tarka with the original interdimensional transporter.
Connected to the theory above, if Tarka is to succeed in his goal of reaching Kayalise then his interdimensional transporter needs to work! He’s convinced that it does, and that the one Oros built at the prison camp also worked. If the two are to have any hope of reuniting, this crucial (and power-hungry) piece of technology is essential.
In narrative terms, the interdimensional transporter is a macguffin right now. But it has huge potential – perhaps opening up future Discovery or 32nd Century stories involving visits to parallel universes. This could even be the way that the outlying story of Calypso is brought into the fold. In short, there are many good reasons to demonstrate its success!
Theory #6: The Guardian of Forever will make an appearance.
The Guardian of Forever in Season 3.
Earlier in the season I’d been speculating that Captain Burnham could turn to the Guardian of Forever for help with the DMA. That didn’t happen (she seems to have entirely forgotten about the Guardian’s existence) but there is still a way to bring the Guardian back into the story in a way that makes sense.
In short, Season 3 saw the Guardian send Georgiou to an alternate reality, so it stands to reason it could do the same for Tarka. The Guardian of Forever is one of the few ways that could allow everyone to get what they want: the DMA could be moved away from Earth and inhabited worlds, Unknown Species 10-C could continue to mine boronite, and Tarka could use the Guardian to travel to Kayalise. There’s also a remote possibility that the Guardian could be used to send the USS Discovery back in time as part of a tie-in with Calypso, but at this late stage in the season I don’t think we’ll get that.
Theory #7: A major character will be killed off.
A Federation funeral service.
This would’ve made more sense earlier in the season, with the death of a major character potentially setting up the danger of the DMA and Unknown Species 10-C, but even at this late stage it could still be impactful. Right now, Tarka has to be top of the list for not surviving the finale. Somehow, Captain Burnham will have to stop him, and one reliable way to do that would be for him to be killed! This happened in Season 1 with Lorca, in Season 2 with Control, and in Season 3 with Osyraa, so Discovery has precedent for killing its villains.
However, there are other possibilities. Lieutenant Commander Bryce is very high on the list following his emotional goodbye with Saru a couple of episodes ago, and had warranted his own entry on the theory list for the past couple of weeks! Then we have Book and Reno, who are trapped with Tarka aboard Book’s ship. One or both of them could be killed, either accidentally or intentionally, during Tarka’s quest to reach Kayalise.
Lieutenant Commander Bryce.
The departures of Gray and Tilly have the potential to shake up the cast as Discovery prepares for its fifth season, but both characters have just left the ship to do other things; they could return at any time and their friends know that they’re safe. A character death – if well-timed and pulled off with the right weight and emotion – can be incredibly impactful, not only to the characters they leave behind, but to us as the audience as well.
At points this season, I’ve felt that Discovery has given even its minor characters some pretty heavy plot armour. And if the aim was to communicate the stakes involved with the DMA and Unknown Species 10-C, a character death this late in the game would miss the mark. But there’s still time for a dramatic twist of this kind!
In ranked order of how likely I think they are to die in the season finale, we have the following characters: Tarka, Bryce, Reno, Tilly, and Booker.
So those theories saw movement this week.
We still have a number of theories left in play, with quite a few seeming increasingly unlikely to be included this season. However, it’s possible for the season to end with a cliffhanger, or for the final act of the season finale to set up something big for Season 5 that could include any of these story elements. I’ll recap the remaining theories here.
Theory #8: We’ll learn more about who Dr Kovich is and what position he has within the Federation.
The enigmatic Dr Kovich.
I have four theories about Dr Kovich that came to the fore in The Galactic Barrier. In that episode, Dr Kovich claimed to have “more important things” to do than accompany the USS Discovery to Unknown Species 10-C’s hyperfield. This prompted a lot of speculation – but with the last two episodes having ignored him altogether, this could be one of those Discovery lines that sounds exciting and interesting… but ultimately has no payoff of any kind.
Regardless, here are my Kovich theories summarised:
Theory #8-A: Dr Kovich works for Section 31.
Sloan, a 24th Century Section 31 leader.
Section 31 is the off-the-books, black ops division of Starfleet Intelligence. They run morally questionable operations and even attempted to commit genocide against the Founders of the Dominion in Deep Space Nine. I originally pegged Dr Kovich as a Section 31 leader back in Season 3 for his treatment of Georgiou. He also seems to have a very wide range of skills and a lot of power: appointing Starfleet Academy instructors, having access to classified intelligence, and acting as a therapist or psychiatrist are all things we’ve seen him do.
Theory #8-B: Dr Kovich is Vice President of the Federation.
If there’s a President then there must be a Vice President!
We got confirmation a couple of episodes ago that President Rillak has an unnamed Vice President. This character was only mentioned briefly and their name wasn’t revealed, so it’s possible they’ll never be shown on screen and won’t matter to the story. However, it seems at least plausible that Dr Kovich is the Vice President; it could account for his powerful role within the Federation hierarchy and give him a reason to remain behind.
Theory #8-C: Dr Kovich is a Q (or similar alien).
Q.
This would be a complete twist, but I wonder if the reason for Dr Kovich’s enigmatic nature is that he’s a member of the Q Continuum. It could be revealed that Dr Kovich is from an alien race and has been observing the Federation while trying to offer limited help and guidance – not dissimilar to how Q operated. This could explain why he seems to offer fairly limited help, at times, or sets up other characters to make breakthroughs with a little prompting.
Theory #8-D: Dr Kovich is preparing a weapon of last resort to strike Unknown Species 10-C.
The Burn as shown in Season 3.
One reason why Dr Kovich may have remained at Federation HQ (regardless of what his job title is) could be to prepare a backup plan in case the USS Discovery’s mission fails. This could take the form of some kind of “weapon of last resort” which could be far more powerful than Tarka’s isolytic weapon. It could also make use of time travel, or even be a weaponised form of the Burn.
Theory #9: Admiral Vance’s holo-message about Earth and Ni’Var was fake or has been tampered with.
Captain Burnham listening to Admiral Vance’s message.
As I said in my review, this is the one part of The Galactic Barrier that I wasn’t wild about. Earth being in trouble is a cliché, and one which really makes the ending of the season feel like an inevitability – with Earth, Titan, Ni’Var, and the rest of the Sol and Vulcan systems in danger, it’s unfathomable that the DMA won’t be stopped in time. But I digress!
If there are other plans afoot at Federation HQ then it’s plausible to think that someone either faked or tampered with Admiral Vance’s holo-message, meaning that the information Captain Burnham and the crew received wasn’t correct. It could lead to an attempt at a dramatic finale, with Captain Burnham thinking she’s too late to have saved Earth… only to discover that Earth is fine because it was never in danger to begin with!
Theory #10: The ban on time travel will be explained in more detail.
The USS Enterprise-E travelled through time in First Contact.
As mentioned above, there may be plans afoot within the Federation and Starfleet to strike Unknown Species 10-C, and a weaponised form of time travel could be a last-resort weapon that the Federation – and other galactic races – might consider using. If so, perhaps the ban on time travel that was introduced in Season 3 will be explained in more detail or expanded upon.
The ban made storytelling sense; it was a way to avoid questions about how the 32nd Century was so different to the far future glimpsed in past iterations of Star Trek, it prevented an easy fix to Georgiou’s health condition, and it prevented any of the main cast returning to the 23rd Century. But it also raised some issues for nitpicking Trekkies like us! The biggest one was how something like this could possibly be enforced; it isn’t possible to un-invent a powerful, weaponisable technology, and even if every single race in the galaxy agreed to the ban in theory, it seems like it would need an incredible level of oversight to enforce it. Finding out more about how the ban works is as much a hope as a theory in some respects, but I think it’s something Discovery should at least attempt to do!
Theory #11: The Federation has flouted the ban on time travel (or is about to).
Book, Burnham, and Sahil with the flag of the Federation in Season 3.
As above, it may be possible that the Federation is about to make a move using time travel to attack Unknown Species 10-C. If so, we may be about to learn that it isn’t the first time that they have failed to abide by the rules set out in the ban on time travel.
It doesn’t seem likely that the DMA is directly related to time travel, as I had previously suggested. But if time travel is about to come into play, we could learn more about the ban and the Federation’s relationship to it.
Theory #12: Unknown Species 10-C built the Galactic Barrier.
The USS Enterprise approaching the galactic barrier.
Given their technological capabilities, it doesn’t seem impossible that Unknown Species 10-C constructed the Galactic Barrier – perhaps as a way to shield themselves from the races of the Milky Way, or perhaps to keep anyone from exploring too far and discovering their location. There are many reasons why a technologically advanced race might want to build something on this scale – and we could even learn that the harvested boronite is being used to fuel the Galactic Barrier itself.
One possible explanation for why Unknown Species 10-C might want to build something like the Galactic Barrier is to keep the Milky Way’s inhabitants in… but it could also be a shield designed to keep someone else out. That raises a very frightening question: what could be so powerful that a barrier is needed around the entire galaxy? And what could be so dangerous that being locked inside a galaxy with the Borg would be preferable?
With Unknown Species 10-C seemingly being very secretive, I think the idea of them building it to shield themselves is more likely… but there are definitely a lot of ways this theory could go!
Theory #13: Someone else built the Galactic Barrier to keep Unknown Species 10-C out.
The Galactic Barrier.
If the Galactic Barrier is an artificial construct, perhaps it was created by another race or faction as a shield against Unknown Species 10-C. It could be the case that Unknown Species 10-C has used DMA technology against the Milky Way in the distant past, and some other race or faction constructed the Galactic Barrier to keep them out. If Unknown Species 10-C are belligerent and interested in conquest, it might take something on a galactic scale to keep the Milky Way safe. A race like the Q could be responsible if that’s the case.
Obviously this theory and the one above can’t both be right! And it’s a distinct possibility that the Galactic Barrier element of the story was just a convenient macguffin to blind Starfleet to Unknown Species 10-C and prevent easy travel to their region of space, dragging out the story and prolonging attempts at communication so other narrative threads could play out.
If that’s the case, we may learn nothing about the Galactic Barrier in the season finale! However, I still think it’s interesting to consider the possibilities, and it could be fun to finally get some more detail on this lesser-known but significant aspect of the Star Trek galaxy.
Theory #14: There will be a character crossover from a past iteration of Star Trek.
Star Trek has had some wonderful crossovers in the past.
There are many ways to bring back a character from a past iteration of the franchise and incorporate them into the story of Season 4 – and there would be many potential benefits to doing so! I had initially proposed a version of this theory in the run-up to Season 3 that centred on the Doctor from Voyager – but with some creative technobabble, practically anyone could be included, despite the leap forward in time.
Choose To Live showed us the Abronians in cryo-sleep, and Stormy Weather saw the crew of Discovery use the transporter buffer to survive – just like Scotty had done in The Next Generation Season 6 episode Relics. Could these be hints at something to come?
It would also be possible for Captain Burnham to discover the logs or a holographic recording of a long-dead character – and while this would be less of a “crossover,” it could still be a ton of fun and great fan-service!
Theory #15: Book will find Kyheem and Leto inside the hyperfield.
Leto in Book’s dreams.
In Star Trek: Generations, Captain Picard encountered Captain Kirk inside the Nexus – despite Kirk being declared “dead” after the Enterprise-B encountered the energy ribbon almost eighty years earlier. Now that we know a little more about how the DMA operates, it seems at least faintly possible that, just like Captain Kirk, the inhabitants of Kwejian may not be as dead as they first appear.
This theory is, I freely admit, a bit of a long-shot. But the wormhole technology that we know the DMA uses seems to be capable of sending some of what it harvests or mines back to Unknown Species 10-C’s base of operations. Maybe that means that some of the people from Kwejian were transported there instead of being killed. Now that Book is inside the hyperfield, could a reunion of some kind be possible?
Theory #16: Michael Burnham won’t remain captain of the USS Discovery.
Lorca was Discovery’s captain in Season 1.
It’s possible that Captain Burnham will have to go to extreme lengths to stop the DMA and/or Tarka, and while I doubt very much that she’ll be killed off, something major could happen in the season finale that sets the stage for her departure from the series.
The developing situation between Captain Burnham and Book could end up with her choosing to resign her commission or taking a new job within Starfleet. Her role as captain of Discovery forced her to choose her responsibility to the Federation over her relationship, and after she was almost forced to kill Book, it would be understandable if Captain Burnham never wanted to be put in that position ever again!
Pike commanded the ship in Season 2.
It wouldn’t be the first time Captain Burnham has been unsure of her place in Starfleet and what role she wants to have. We saw this in Season 3 as part of the background that set up her eventual ascent to the captaincy, and while it seems unlikely that it will come back into play in a big way, the situation with Book could be a catalyst for Captain Burnham wanting to have a simpler life either outside of Starfleet or, at the very least, out of the captain’s chair.
This would also continue a trend that Discovery has had across all four seasons thus far: the rotating captaincy of the ship. Each season has seen a new captain in command, and with Season 5 in the offing, it’s got to be at least possible that this trend will continue. I’m not really in favour of this, but it’s certainly interesting to consider. Because Captain Burnham has been the show’s protagonist since Season 1, it seems unlikely, and the overall arc of Discovery between Season 1 and Season 3 can be read as her redemption and ascent to the captaincy. But the show’s revolving door of captains may continue, and her conflict with Book and the difficult emotional situation it put her in could be the trigger to make this happen.
Theory #17: Saru will be given the captaincy of the USS Voyager-J.
Captain Saru in command… of a shuttle!
Saru’s future was briefly discussed before he offered to serve as Captain Burnham’s first officer in the episode Anomaly. He has already been offered a command of his own, so Starfleet clearly values his command abilities and experience. President Rillak was seen to be assessing Captain Burnham’s suitability for the captaincy of the USS Voyager-J in Kobayashi Maru… and she mentioned having a shortlist of candidates. Could Saru be on her list?
Several of the qualities that President Rillak said she was looking for in a potential captain seem to apply to Saru. He’s more level-headed, less likely to put himself in a dangerous situation, and more inclined to think of the big picture. He has a weakness when it comes to Kaminar, as we saw toward the end of Season 3, but generally speaking he isn’t someone who lets his emotions get the better of him. His wisdom and calm demeanour could be valuable in the captain’s chair of the Federation flagship. This could also set the stage for his departure from the show, or possibly even for a new show following his adventures aboard his new ship.
Theory #18: Season 4 will connect with the Short Treks episode Calypso.
The USS Discovery in Calypso.
Zora’s status as a member of the crew was confirmed in But To Connect, and this followed her developing emotions and sentience earlier in the season. Zora is now much closer to her presentation in Calypso, potentially bringing the story of the Short Treks episode one step closer.
With just one episode remaining and a lot of other storylines to get through, this one feels less and less likely – but it could be an interesting cliffhanger ending if the ship had to be sent back in time!
Theory #19: Some areas of the galaxy – such as the Delta Quadrant – avoided the worst effects of the Burn.
Adira and Stamets with a map of the Milky Way galaxy.
In But To Connect, President Rillak told us that the diplomatic summit she convened would bring together races from “all four” quadrants. Assuming she was referring to the familiar Alpha, Beta, Gamma, and Delta Quadrants that make up the Milky Way galaxy, this would count as our first mention of the Delta Quadrant in the 32nd Century. I didn’t spot any familiar Delta Quadrant races (or their emblems) amongst the assembled delegates, however!
I had previously speculated that the Burn may not have affected the entire galaxy equally, and that regions farthest away from the Verubin Nebula may have survived without much damage. I still think that this is a possibility – though whether Discovery will revisit the Burn in any depth, or visit the Delta Quadrant at all, remains unclear.
Theory #20: The crew will have to defend the Verubin Nebula.
The dilithium planet is vital to the Federation.
This one is definitely hanging by a thread right now, at least in terms of Season 4! The story continues to unfold in a very different direction, largely ignoring the main story beats from Season 3. But the dilithium shortage has been mentioned more than once, and as things stand right now, the Federation is in control of the galaxy’s only significant dilithium supply. The Verubin Nebula is almost certainly going to be a target for somebody – even if Unknown Species 10-C don’t care about it.
It begins to stretch credulity to think that all of the belligerent factions and races present in the galaxy would become aware of the Federation controlling this impossibly valuable resource and wouldn’t want to take it for themselves. And while it may not happen now until after the DMA storyline has run its course, I think sooner or later someone is going to want to steal the Verubin Nebula and its dilithium. Maybe it will be at the end of Season 4, maybe it will be in Season 5… who knows?
Theory #21: Tarka will create his own DMA.
Tarka and Stamets Saru with their DMA model.
In The Examples, we saw Tarka – aided by Stamets – building a scale model of the DMA. Now that his plan to destroy it and seize its controller has failed, perhaps he’ll attempt to recreate the device using the knowledge he acquired. If so, he could inadvertently create a new DMA. Or, through time travel shenanigans, Tarka could turn out to be the creator of the original DMA!
If Tarka isn’t able to find a power source for his interdimensional transporter on the far side of the Galactic Barrier, he may feel he has no choice but to try and recreate the DMA’s original power source.
Theory #22: We haven’t seen the last of the Abronians.
I currently have four ideas for different ways that the Abronians – the non-humanoid race that Captain Burnham, Tilly, and the Qowat Milat helped save from cryo-sleep in the episode Choose To Live – could play a further role in Season 4. Time is ticking away… but it’s still possible!
Theory #22-A: The Abronians’ homeworld was destroyed by the DMA.
Captain Burnham believes this image depicts a “supernova.”
After arriving at the Abronians’ cryo-ship, Captain Burnham found a stone carving that seemed to depict the destruction of the Abronians’ homeworld. This carving was only shown on screen briefly, but it seemed to show the planet being damaged or destroyed in a large explosion. Burnham credited the planet’s destruction to a “supernova,” and the story then raced ahead.
We’re running out of time with this one – and it could be that Captain Burnham’s initial observation was correct. But this would be one way to connect this side-story to the season’s main narrative arc.
Theory #22-B: The Abronians’ homeworld was on the other side of the DMA.
Abronian stasis pods.
One thing struck me as odd about the Abronians: the Federation was entirely unaware of them, despite the Abronian cryo-ship being relatively close to Federation space – such that Captain Burnham could reach it using Book’s ship in a short span of time. It’s possible that the Abronians had been asleep for millennia, unnoticed by the Federation and the wider galaxy for all that time. But it’s also at least possible that their cryo-ship is a newcomer to the area.
Having seen the destruction present on Unknown Species 10-C’s ex-homeworld, maybe the Abronians fell victim to the same devastating event if their original planet was in the same region of extragalactic space.
Theory #22-C: The Abronians will return to help the Federation.
A deceased Abronian.
One of the themes of Discovery since Season 3 has been connection, including building connections between the Federation and other races and organisations. The Abronians were awoken from cryo-sleep thanks to the interventions of Captain Burnham and Tilly – at least in part – and they may seek to repay the Federation, or Captain Burnham personally, for that help.
We saw this play out last season with Ni’Var; in the season finale Ni’Var ships raced to the Federation’s aid as the Emerald Chain attacked. Perhaps the Abronians will likewise step up to help when the Federation needs allies.
Theory #22-D: The Abronians’ moon-ship may be useful in a later story.
“That’s no moon…”
The cryo-ship used by the Abronians was huge, and appeared to have the mass of a planetoid or small moon. With Earth and Ni’Var now under threat and an evacuation necessary, perhaps the Federation will ask the Abronians to borrow their moon-ship. This could even be what Dr Kovich was planning to do and why he couldn’t join Discovery on the mission through the Galactic Barrier.
The moon-ship was fully operational thanks to the new dilithium that J’Vini “procured,” so it could be commandeered by Starfleet for the purposes of an evacuation. That would be one way to pay off what is, at the moment, a side-story.
Theory #23: Kayalise is the Kelvin universe.
The titular USS Kelvin.
Oros didn’t make clear, in the flashback sequences we saw, exactly what Kayalise would be like. He only believed that it would be better than the prime universe, and talked about it in mythological, almost religious terms. That could mean something significant, or it could simply be Oros being poetic!
Tarka had previously suggested that the universe he hopes to escape to is one where the Burn didn’t happen and the Emerald Chain never rose to power. Because of the unique circumstances of the Burn, it seems at least possible that it didn’t occur in the Kelvin timeline – the one established by 2009’s Star Trek. We’ve already had at least one Kelvin reference in Discovery’s 32nd Century, confirming that the universe was known to exist and was reachable. With a fourth Kelvin film in early production, it’s possible that Kayalise is actually the Kelvin universe!
So that’s the main theory list!
We now have three production-side theories in play, so we’ll look at those too before we wrap things up.
Production-side theory #1: There will be some kind of crossover with Star Trek: Picard Season 2.
Picard Season 2 is running alongside Discovery.
This theory has arisen in large part because of the very odd scheduling of Picard Season 2 and Discovery Season 4, which will run alongside each other for three episodes. I wonder if that’s because some kind of crossover is on the agenda. With time travel playing a significant role in the story of Picard Season 2, it seems at least plausible to think that some kind of connection is possible!
This could be a complete over-reach, and the ultimate “explanation” for the weird scheduling may turn out to be nothing more than the random illogical spasms of the ineptly-managed Paramount+ and parent company Paramount Global. That would not surprise me in the slightest! But I really do find the scheduling odd.
Admiral Picard.
The shorter seasons of today’s Star Trek shows means that there really isn’t any need for such a pile-up this spring. Discovery has thirteen episodes, Picard and Strange New Worlds have ten apiece – and even with Lower Decks and Prodigy still to come, there are more than enough weeks in 2022 for the entire Star Trek franchise to be evenly spread out. Why have four out of ten weeks with two episodes from two different shows, then a gap of several weeks later in the year where no new Star Trek is broadcast? It makes no sense – especially not on a streaming platform.
Finally, with the constipated international rollout of Paramount+ showing no signs of speeding up, it’s looking increasingly likely that Strange New Worlds will be broadcast in the United States weeks or months ahead of its international premiere. If both Picard Season 2 and Strange New Worlds were delayed by as little as 5 or 6 weeks, this might be able to be avoided – assuming the rollout of Paramount+ “by the end of Q2” happens as planned.
In short, it’s all very strange – but one possible explanation for the weird scheduling could be that there’s a crossover event planned sometime in the next three weeks!
Production-side theory #2: Tilly’s departure will be permanent.
Tilly’s departure feels permanent.
Mary Wiseman confirmed in an interview with Wil Wheaton on The Ready Room (Discovery’s social media aftershow) that Tilly will be seen again before the end of Season 4, and we glimpsed her in the trailer for the second half of the season as well. But that doesn’t mean she will return as a main character on the show going forward, and her departure in All Is Possible felt permanent. Despite that, I’ve seen quite a lot of folks online who don’t believe that Tilly is actually leaving the series – so I wanted to put it out there officially and say that, in my opinion anyway, she is.
Maybe those people know something that I don’t! As I always say, I don’t have any “insider information;” all of this is just speculation on my part. However, I feel that the manner of Tilly’s departure, the fact that she got that emotional sequence with Captain Burnham, a montage showing her leaving the ship, Adira seeming to take over several of her roles, and her departure feeling like the culmination of her arc going back to the latter part of Season 3 all come together to strongly indicate that she won’t be back as a major character. She may yet have a significant role to play in a future Season 4 episode, as has been suggested, but unless Discovery’s writers are really playing with our emotions I believe we’ve seen Tilly’s end as a main character on the show. She may come back in a future Starfleet Academy series, though… so watch this space!
Production-side theory #3: Season 4 will end on a cliffhanger!
Star Trek has a long, well-established tradition of season-ending cliffhangers! There have been some truly shocking ones in the past, including The Best of Both Worlds in The Next Generation, Deep Space Nine’s Call To Arms, Equinox in Voyager… and many more! With the story of Unknown Species 10-C and the DMA slowly being unpicked, it could be the case that we’ll get a clean resolution – like we did at the end of Season 3. But it’s also possible, in my opinion, that Season 4 will end in similar fashion to Season 2 – on a major cliffhanger!
That could be because the Unknown Species 10-C story didn’t conclude, or a war with the mysterious faction is about to break out. But the Season 4 finale could also set up the beginnings of Season 5’s story, just like how the final moments of Season 1 saw Captain Pike’s Enterprise link up with the USS Discovery.
So that’s it!
The USS Discovery and Book’s ship in Species Ten-C.
We still have a long list of theories as we head into the season finale. Obviously most of them won’t pan out – there isn’t time in a single episode to pay off even half of those still on the list! But they all seem possible or plausible to me, and with a fifth season of Discovery having been confirmed, maybe we’ll see some of them return in 2023 when I start putting together my Season 5 theories!
I always like to end these theory lists by saying that I do this just for fun. I enjoy writing, I enjoy Star Trek, and spending more time in this world is an escape and an enjoyable distraction. But for some folks, fan theories can be frustrating or unenjoyable, especially if they get very attached to a plausible-sounding theory that ultimately doesn’t pan out. I have no “insider information” and I’m not trying to claim that anything suggested above can, will, or must be part of Discovery Season 4. I fully expect many of these theories to be debunked and for the season to go in wildly unpredictable directions!
Star Trek: Discovery Season 4 is available to stream now on Paramount+ in the United States, Scandinavia, Latin America, and Australia. The show is on Pluto TV in the UK, France, Germany, Italy, and other parts of Western Europe at 9pm on Fridays and Saturdays. Individual episodes or the full season can be purchased on iTunes, Amazon Video, Google Play, and possibly other platforms in the UK, parts of Europe, and select other countries.

Species Ten-C wasn’t just a good episode in its own right, with plenty of excitement and tension that showed how Star Trek can do a heck of a lot without resorting to violence and battles, but it was one that made the episode immediately preceding it significantly better in retrospect. I wrote last week that the one saving grace to an otherwise frustrating experience in Rosetta could be if the hydrocarbons discovered by Captain Burnham and the away team were put to good use – and that happened in a big way this time.
On the other side of the story, I finally felt what I believe the writers have been aiming for for weeks with the Book and Tarka storyline: that Captain Burnham was right, diplomatic initiatives should be given a chance, and that Book has fallen victim to Tarka’s manipulations. While this has the unfortunate effect of relegating Tarka from a complex character with an equally understandable motivation into the out-and-out villain of the season’s final couple of episodes, it clarifies what had been until now a very fuzzy and occasionally frustrating story.
The Book and Tarka storyline was expanded upon in a big way this week.
If I were to be critical of Species Ten-C, what I’d say is that it probably took too long for the season to reach this point. Several advances in the DMA/Unknown Species 10-C storyline were sprinkled in at or near the end of unrelated or tangentially-related episodes, with the Federation often running into problems or delays that took too long to surmount, and the result of that is that it took a long time to arrive at the hyperfield.
The story of finding a way to bridge the communication divide could have been a longer one, and it was handled in a genuinely interesting way – but with only half an episode dedicated to it here and just one final episode of the season remaining, it’s an interesting concept that may not be explored in as much detail as it could have been.
Species Ten-C saw the crew making first contact.
This story of learning how to communicate with someone far more alien than usual, and doing so while under threat thanks to the DMA, is not one that required a B-plot villain. While Tarka was interesting in his earlier appearances and his motivations were laid out in a clearly understandable way, the narrative just doesn’t require this additional element in order to be exciting.
Discovery has a tendency, as I’ve pointed out on a number of previous occasions, to try to inject double the tension and three times the drama when it just isn’t necessary, and if I were to make one comment about the series as a whole it’s that the writers need to have more confidence in their stories. Dropping the Tarka angle, or reworking it to make him less of an antagonist in this final chapter, would allow the main story of learning to communicate with Unknown Species 10-C to stand on its own – and as it’s already sufficiently tense, interesting, and engaging, Tarka’s villainy just isn’t necessary.
Tarka in Species Ten-C.
Not for the first time, Discovery has set up a character who feels well-rounded and complex, with motivations that seem understandable, only to turn them into a pretty standard villain later on. I wouldn’t have even called Tarka “morally ambiguous;” his weapon plan made a lot of sense when it was first proposed, and I even suggested that a show which has had themes of seeking a “middle ground” could have figured out a way to keep Tarka on board, building his weapon as a back-up plan while attempting to make first contact. But as with Captain Lorca in Season 1, much of Tarka’s nuance now feels lost; brushed aside because the writers determined that the season needs a villain.
There were other ways to formulate this story that either skipped over Tarka altogether or that kept him in that complex space. We may yet learn that his interdimensional transporter will be important, in which case he may have served a narrative function, but if the ending of the story is going to be Tarka’s defeat or death, with a reunion with Oros not being able to happen, then I think I’ll have to go back and re-evaluate his role in the season overall. This story already had the complexities of Unknown Species 10-C and the DMA; I’m not sure it needed a second antagonist, especially not one who seems to have come at the expense of an interesting and complex character.

We’ve also got to talk about the new character of Dr Hirai. In short, he needs to do something truly outstanding and unique next week – otherwise his inclusion in the season will have proven to be a complete and utter waste of a great actor. I like the concept of the character; a linguistics and communications expert seems perfect for this kind of mission. But in his two earlier appearances this season he did nothing whatsoever, and his accomplishments this week were relatively minor. It didn’t feel like bringing Dr Hirai along was in any way important to the success of the mission, with Captain Burnham, Zora, Saru, and even characters like Detmer, Nilsson and the very minor Lieutenant Christopher all contributing at least as much – if not more – to the story as he did.
He was ultimately sidelined by President Rillak, who chose Saru and Burnham over him for their linguistics and first contact expertise, confirming his relegation to a bit-part role at best. In light of what happened last week with Rosetta, I’m willing to wait and see if Dr Hirai will yet make a significant contribution – but with only one episode left in which to do so, he needs to do something big pretty quickly or we’ll unfortunately have to consider his inclusion in the story a bit of a let-down.
Dr Hirai doesn’t have long left to make an impact on the story.
There is one concept underlying the way Unknown Species 10-C reacted to Discovery’s arrival – and the conversation it prompted between Captain Burnham and the others – that I didn’t like. As humans, we’re able to recognise signs of intelligence in other species, even though we’re far more advanced and intelligent than they are. We can recognise the complex social structures present in ant colonies, for example, or how crows and some great apes are learning to use tools. Even though these creatures are far lower on the intelligence scale than we are, we’re able to determine quite easily that animals – even small and lowly ones – can exhibit signs of complex understanding and intelligence.
With that in mind, the idea that Unknown Species 10-C would see a starship arriving at warp speed, using a warp core and a spore drive, built from clearly artificial alloys, and somehow not understand that the creatures aboard it are sentient makes no sense. This species is supposedly much farther advanced than even the 32nd Century Federation, and even though they exist outside of the galaxy they must have the ability to scan and detect the existence of other sentient species, even if they choose not to interact with them. It’s conceivable that they might be selfish and not care about any other species besides themselves – but the idea that they would be unaware or incapable of determining intelligence in this situation is one that I can’t buy as a believable story point.
The USS Discovery approaches the hyperfield.
It seemed at first as though Species Ten-C was going to centre on this aspect of first contact, and I was certainly a little disappointed at first. But thankfully this didn’t last too long, with Unknown Species 10-C eventually getting the message and realising that the life-forms aboard the warp-capable starship are actually intelligent. Took them long enough!
I know that probably sounds like a nitpick – and it is, in a way. It’s just that, despite all of the talk of Unknown Species 10-C being very alien and having a very different culture, some things should be universally obvious – like if someone is capable of building a starship that can travel faster than the speed of light, use metal alloys that don’t exist in nature, and fly right up to your base to initiate contact, it’s probably a safe bet to assume that they possess some degree of intelligence. That should apply no matter who you are! And as pointed out above, humans are capable of recognising the signs of intelligence in the natural world. As a narrative beat, I get that it was in there to make the initial meeting feel very tense, but it’s kind of illogical if you think about it!
A representative of Unknown Species 10-C.
We didn’t get a clear look at Unknown Species 10-C, as their representative was partially obscured by a cloud of swirling gas. Nevertheless, the visual effects on this side of the story were mostly high-quality, and Unknown Species 10-C themselves at least seem like they’ll be visually interesting if we ever get a better look at them. I actually got a slight “Mass Effect Leviathan” vibe from what we glimpsed of Unknown Species 10-C. The design of the hyperfield was likewise interesting; it appeared much more solid than I had been expecting based on the holographic projections seen in previous episodes. Seeing it go from solid-metallic looking to swirling like fluid was also a very cool visual effect that Discovery executed well.
The only visual that I felt was a bit of a miss was Unknown Species 10-C’s shuttle pod/diplomatic chamber. When it arrived in Discovery’s shuttlebay it looked rather bland and low-quality, like a video game where a texture hasn’t loaded properly. It was clearly designed to look similar to the hyperfield, but I guess trying to blend that with a real set and real actors was difficult. It didn’t look awful, but it was noticeably lower quality when compared to the rest of the visual effects and animation work present in Species Ten-C.
This visual effect felt rather weak.
The idea of Unknown Species 10-C recreating part of Discovery as an environment for the crew works as a story point – I can quite understand why they’d choose to do something like that. But I confess that I rolled my eyes a little when I saw Captain Burnham and the others stepping onto the bridge set. It was understandable in the context of the story, but it didn’t make for a particularly impressive or interesting sequence when shown on screen. In fact, it almost makes Species Ten-C feel like a “bottle” episode – a Star Trek trope going all the way back to The Original Series where episodes would be set entirely aboard the ship.
As mentioned above when discussing Dr Hirai, President Rillak chose to bring both Captain Burnham and Saru when boarding Unknown Species 10-C’s diplomatic shuttle. And aside from totally sidelining Dr Hirai, this also left the command structure of Discovery and the rest of the mission uncertain. Rhys had the ship’s conn, as we’d see on the bridge near the episode’s climax, but who was in charge of the remaining delegates and the rest of the diplomatic mission? And how far did Rhys’ authority extend? Would he, for example, have been authorised to fire upon Unknown Species 10-C if time began to run out for Earth? Taking both the captain and first officer on this mission – when other experts were available – is a bit of an odd choice, and while of course as the audience we want to see our familiar characters leading the charge, it again makes the addition of some of these other delegates and experts feel like a bit of a waste.
The interior of Unknown Species 10-C’s pod.
A longer episode – or a story which had arrived at the hyperfield earlier in the season – could have spent longer on the whole first contact thing, and I really think that would have been worth doing. I’m actually getting a bit of a familiar feeling the more I think about Species Ten-C: it reminds me of the finale of Picard Season 1 in the sense that the season dawdled a lot to get to this point, and it feels like there’s a lot of important story points left to get through with very little time remaining. As a result, some aren’t being given as much attention or screen time as they probably should receive. We aren’t at the same level as Et in Arcadia Ego – at least, not yet. But suffice to say that Season 4 as a whole has left its final episode with a lot of work to do to wrap up all of the major stories in a satisfying way.
There were a few very close-up shots of characters’ faces that made the cinematography in Species Ten-C feel a bit odd. Close-ups can work and can be dramatic, but their use here felt rather gratuitous, with the episode both beginning and ending with them in a way that made it feel like the director was throwing everything at the wall in an attempt to make things seem even more dramatic. As I’ve said on several occasions this season when discussing certain narrative choices, Discovery is already a series that brings plenty of drama to the table – trying to take it from a ten to an eleven can sometimes fall flat, and a few of these extreme close-ups definitely strayed very close to the line.
Was there any need for so many close-up shots?
Book saw some significant character development this week after several episodes in which he felt very static. Although Tarka’s motivation for continuing to pursue the DMA’s power source feels pretty well-established by this point in the story, I’ve been finding it increasingly difficult to reconcile Book’s presence on this side of the story in the aftermath of the failure of the isolytic weapon back in Rubicon. We hadn’t seen or heard enough from Book since that dramatic event to signal that he’s still on board with the next phase of Tarka’s plan – and this week he actually seems to have moved much closer to Burnham’s position.
Book’s cause is noble: he wants to stop the DMA from hurting anyone else in the way it destroyed his home and hurt him. And seen in that context, his decision to get on board with Tarka’s weapon plan was understandable. In Rubicon, Book indicated he would be willing to stand down for a short time to give diplomacy a chance to play out, and in the aftermath of the failure of the weapon, it wasn’t clear at all why he continued to follow Tarka. I’m still not exactly sure how he arrived at this point – was he motivated by fear of repercussions for the use of the weapon? Did he still believe it would be possible to destroy it after Tarka failed once? If so, is he now no longer willing to let Captain Burnham try for a diplomatic solution first?
Book in Species Ten-C.
These points were glossed over in Species Ten-C, but we finally got some movement from Book, arguably bringing him back into the fold as one of the “good guys.” It emerged that Tarka’s plan would destroy the DMA, destroy Earth, and destroy the hyperfield containing Unknown Species 10-C and the USS Discovery – so Book didn’t really have a choice! Again, this is Discovery pushing the story to extremes, and it feels as though Book coming back to the light is more of a necessity than a choice at this point. Still, it worked, and for the first time in several episodes I felt like I could relate to Book as a fully-rounded character again, not just a plot device caught up in the narrative wake of other characters with more volition.
There’s even a message in Book’s story, if we look a little deeper. The idea that grief can lead someone to a very dark place was already something we’d seen explored a little with Book earlier in the season, but now we can add into the mix themes of manipulation, of being lied to, and of getting involved with someone untrustworthy. It was initially grief that saw Book teaming up with Tarka, but he also had the noble objective of wanting to prevent others from having to experience that same level of grief. Unfortunately for Book, he relied on someone who turned out to be unworthy of his trust – and that’s how he ended up in this particular predicament.
Grief led Book down a dark path.
Reno saw her best scenes of the entire season on this side of the story, too. We’ll have to try to excuse the lousy “kidnapping” plot last week, because as weak and difficult to explain as that may have been, it ended up going somewhere significant. It didn’t necessarily have to be Reno as the one to reach out to Book – basically anyone on board the ship could’ve done so – but it was interesting to see her in this situation. Her words managed to reach him in a way that even Captain Burnham hadn’t been able to, and the sequences between the two of them worked exceptionally well.
Reno has often been used as a light-hearted character, bringing moments of deadpan comic relief that could lead to brighter moments in otherwise dark stories. This time, her role harkened back to her introduction in Season 2 – which was also referenced this week – when we first encountered her trapped aboard a crashed starship. A more serious performance from a comedic character carried a surprising amount of weight, and perhaps it’s because we know how Reno usually behaves and speaks that her words to Book meant a lot.
This was Reno’s best episode of the season.
For at least the past three episodes, Discovery seems to have been building up to a conclusion which is going to say something like: “if only Tarka and Book had told Captain Burnham what they were doing! It should have been possible for everyone to get what they want through diplomacy and communication!” and I don’t think that’s changed. It isn’t exactly formulaic, and there are still big questions about what Unknown Species 10-C will do and how Captain Burnham will respond to try to cool things down in the time that remains. But one way or another, the story’s going to get to that place.
As we approach the end of the season, feeling like we know roughly where the story is going to go was to be expected, I guess! And on its own merits, Species Ten-C was a good episode, one of the better offerings from Season 4 for certain. Whether it has moved things along far enough for the season finale to wrap up all of the remaining narrative threads is an open question, one we’ll have to wait until next week to get an answer for.
Book’s ship escaped the USS Discovery and entered the hyperfield.
Although I had some nitpicks within the story, overall I had a good time this week. Species Ten-C told a very “Star Trek” story, with perhaps some inspiration from the film Arrival in there too! Meeting a brand-new alien race and learning how to communicate is something truly interesting, and my biggest complaint is that I would have liked to have seen more of it – for the season to have reached this point a couple of episodes ago so we could have spent longer with Captain Burnham, Saru, President Rillak, and Dr Hirai as they worked on figuring out how to use a complex arrangement of lights and pheromones to communicate. It was nice to see some significant movement from Book, too, after several uninteresting or flat episodes on that side of the story.
Did Season 4 need to turn Tarka into a villain? I think that could be a question for a longer essay once the season has wrapped up! I could certainly entertain the argument that the Unknown Species 10-C story – one of misunderstanding, communication, and first contact – was strong enough to carry both this episode and the bulk of the season without requiring this kind of last-minute character twist. Between the DMA and the smaller character moments – some of which, as noted last week, haven’t been as thoroughly explored as they could have been – maybe it would have been better overall to find a different way to include Tarka. But we’ll talk about that more in the weeks ahead, perhaps.
For now, there’s only one episode remaining! This time next week it’ll be all over… or will it? Could a cliffhanger ending be on the cards?

I felt that Rosetta wasn’t exactly the high-water mark of Discovery’s fourth season. My complaints on the narrative side of things boiled down to the fact that the unnecessary and rather clumsy insertion of the tired old “there’s only hours left to save Earth!” cliché meant that Captain Burnham’s decision to divert from the hyperfield to visit a planet was framed in a way that made her seem like she was in the wrong. This mistake was then compounded by the ship and the rest of the crew sitting around doing nothing for the duration of the episode, and a B-plot featuring Tarka and Book that was contrived in the extreme.
Rosetta didn’t do much for the theory list, either! Most of the theories that I have in play relate to Unknown Species 10-C, what may or may not be going on back at Federation HQ, and so on. Because this side-mission essentially ignored most of those narrative threads, this week has seen relatively little theory movement.
That being said, we do have a few updates and one confirmed theory. As always, that’s where we’ll start!
Confirmed theory: Book and Tarka will cross the Galactic Barrier.
Book’s ship and the USS Discovery in orbit of Unknown Species 10-C’s ex-home planet.
I’m disappointed that we didn’t get to see any of Book and Tarka’s transit of the Galactic Barrier. As of the 32nd Century, crossing the Barrier is something that Starfleet still hasn’t been able to accomplish due to the dangers and technological difficulties, so it would have been interesting to see how Book’s ship – a smaller and more manoeuvrable craft than the USS Discovery – might’ve managed the crossing.
Unfortunately, though, we didn’t get to see that for ourselves, with Rosetta kicking off after Book and Tarka had already made the transit. Given their waste of a storyline in the episode, I’d rather have spent time with them as they went through the Galactic Barrier instead of watching them sneak aboard the ship. At least then we’d have felt there was a decent payoff to their mission to the abandoned prison camp. But regardless, this theory counts as confirmed because Book and Tarka did indeed cross the Galactic Barrier, even if they did so off-screen.
So that theory was confirmed.
Up next, we have a couple of new theories and a handful of updates, so let’s take a look at what’s new or different after Rosetta.
Theory #1: The bones that the away team found belong to animals, not Unknown Species 10-C.
A bone on the surface of Unknown Species 10-C’s planet.
The away team found a lot of different bones and fossils on Unknown Species 10-C’s ex-homeworld, some of which were huge. Captain Burnham and the others assumed that the bones belonged to Unknown Species 10-C themselves, but didn’t seem to consider that other animals might’ve shared the planet with them. It seems plausible to me that Unknown Species 10-C may have kept pets or domesticated animals for food, and that at least some of the large bones could be from non-sentient creatures.
The hydrocarbon pheromone-dust, however, does seem likely to be something that Unknown Species 10-C uses for themselves. I hope that the next couple of episodes will find a way to include this discovery… it might go some way to salvaging something meaningful from an otherwise disappointing episode.
Theory #2: Unknown Species 10-C is a faction from a past iteration of Star Trek.
The super-synths’ mechanical tentacles from Picard Season 1.
This theory is officially on its last legs. If Captain Burnham and co. did in fact visit Unknown Species 10-C’s home planet, and if the remains they found are truly the fossilised bones of members of this species, there really aren’t many options from Star Trek’s past that could explain who they are. Perhaps the Picard Season 1 super-synths, if they were once organic beings, could remain in contention. If a way around their origin in the Andromeda Galaxy could be found, then the Kelvan Empire might also remain on the list. I guess the Q Continuum could be an outside possibility, if they once had physical form before they became super-beings.
An alternate take might be to say that Unknown Species 10-C has a connection to a faction from Star Trek’s past, which we’ll look at in a moment. But I think we’re crossing more and more possible suspects off the list that I wrote a while back! And those few that remain feel less and less likely. Comments from Discovery’s showrunner Michelle Paradise about designing Unknown Species 10-C could also count against this theory.
Theory #3: Unknown Species 10-C is connected to a faction from Star Trek’s past.
A Borg cube.
If Unknown Species 10-C are brand-new to Star Trek, that doesn’t altogether rule out a connection with the rest of the franchise. Even if Unknown Species 10-C have never been encountered by the Federation – nor even rumoured to exist in any way that the Federation came to hear about – it’s still possible to tie them to someone we’ve already encountered.
For example, Unknown Species 10-C could have been targetted for assimilation by the Borg in the past. Maybe a powerful race like that devastated their homeworld and forced them to create the hyperfield. They could have also been disturbed accidentally somehow, such as by the USS Enterprise’s transit of the Galactic Barrier. If the devastating event that ruined their homeworld happened approximately 1,000 years ago, the timelines could line up for something like that.
The USS Enterprise approaching the Galactic Barrier.
There could be a connection to the mycelial network, which is something Discovery hasn’t looked at in detail since Season 2. Perhaps Unknown Species 10-C created their own spore drive technology, or maybe the Federation’s use of the mycelial network disturbed or caused harm to Unknown Species 10-C somehow.
In short, there are a lot of ways that Unknown Species 10-C could be connected to Star Trek’s past, even if they’re brand-new to the franchise. We’ll have to wait and see, but it would be very interesting to learn that some kind of connection exists!
Theory #4: Unknown Species 10-C is extinct.
R.I.P.
Given the scale of the devastation their home planet appears to have faced, it’s no surprise that some members of Unknown Species 10-C appear to have perished. What we don’t know, though, is how many of them managed to escape. Captain Burnham and Dr Culber seemed to think that they would have known what was coming well in advance and been able to plan an evacuation – but that may not be the case. If the devastating event caught them by surprise, a full-scale evacuation may not have been possible. It’s possible that only a few individuals escaped – or maybe no one did.
Even if large numbers of Unknown Species 10-C escaped what happened to their planet, there’s still a millennium in which other tragedies might’ve befallen them. The disappearance of dilithium from the galaxy and the Burn are two relatively recent events that could have had a massive impact on a civilisation dependent on a hyperfield in space to survive – but there could be others. If they were fighting a war, for example, the war may not have ended when their homeworld was attacked. Captain Burnham and the crew could arrive at the hyperfield to find it deserted.
Theory #5: Unknown Species 10-C is responsible for the galaxy’s dilithium supply running out.
A large dilithium crystal.
In Season 3, the reason for the dilithium shortage was never explained – it seems as though no one knew why finding a new dilithium supply was becoming so difficult. That makes a good analogy for fossil fuels here in the real world in some respects (though the ending of the season and the reveal of a dilithium planet kind of ruined that), but in terms of an in-universe explanation, could we be on the verge of finding out what really happened?
Perhaps Unknown Species 10-C used to use dilithium as their power source, but when supplies ran out in their local area, they used similar technology to the DMA to strip-mine it from the Milky Way, with their powerful wormholes stripping dilithium away and sending it back to the hyperfield. As dilithium supplies inside the galaxy dried up, Unknown Species 10-C may have then switched to a boronite-based power source.
This would be an interesting way to connect Seasons 3 and 4 together!
So those theories are new or saw movement this week.
As always, in order to keep the theory list intact and in one place, I’ll recap the rest of the theories that are currently in play as we approach the final two episodes of the season.
Theory #6: Dr Kovich works for Section 31.
Dr Kovich in the Season 3 episode Terra Firma, Part 1.
I struck this theory off the list a few weeks ago, when it seemed like Dr Kovich’s role was a more conventional one within the hierarchy of the Federation. But it returned to the list because of his mysterious behaviour in The Galactic Barrier!
Section 31 is the Federation’s off-the-books black ops organisation, and with Dr Kovich seeming to occupy a powerful position, it makes sense that he could be running it – or a senior figure within it. I’m not sure at this stage whether his line about having something more important to do will actually be paid off in a significant way; it felt like one of those seemingly-important lines that Discovery sometimes throws out only for it to come to naught in the end. But if Dr Kovich is going to have a significant role to play later on, perhaps we’ll finally learn exactly who he is and why he’s so influential.
If Dr Kovich is involved with Section 31 – or a similar organisation – we arguably saw hints as far back as his first appearance in Season 3. The way that he debriefed Georgiou, and later declined to reveal her impending health condition until after it manifested, could indicate that Dr Kovich is rather cold and calculating – traits we would associate with Section 31.
Theory #7: Dr Kovich is the Federation Vice President.
If there’s a President there must also be a Vice President, and in The Galactic Barrier we got confirmation of this when President Rillak stated her intention to transfer power to the VP while she was away. As also happened with Tarka’s friend, the name of the Vice President was kept deliberately hidden during the conversation between Rillak and Admiral Vance, which could mean nothing – or it could mean we’re set for a revelation later on!
There aren’t any other named characters – or even background characters – that we’ve seen with President Rillak or around Federation HQ who could be the Vice President, so unless it’s a brand-new character – which is definitely a serious possibility – Dr Kovich is pretty much the only candidate I can think of! It’s possible that this character won’t have any bearing on the rest of the season and was just mentioned in dialogue, but it’s also possible that the VP will have to take significant decisions in the President’s absence.
Theory #8: Dr Kovich is preparing a weapon of last resort to strike Unknown Species 10-C.
The meeting at which Dr Kovich revealed he has other things to do.
What could be more important than making peaceful first contact with an advanced alien race who have the power to destroy entire planets? No one at the meeting seemed to know – or at least chose not to speculate out loud. One possibility that I can think of, though, is that Dr Kovich is putting contingency plans in place to attack Unknown Species 10-C in the event that President Rillak and Captain Burnham fail in their mission.
With Earth and Ni’Var – two of the Federation’s founding worlds – now under direct threat, the time may have come to step up plans for a major attack. This could take the form of a preventative strike, designed to stop Unknown Species 10-C or dissuade them from continuing with the DMA, or it could be a “weapon of last resort,” designed to retaliate in the event that Earth and Ni’Var are destroyed.
Tarka’s isolytic weapon.
If Dr Kovich is involved with an organisation like Section 31, the possibilities for weapons are almost unlimited – we have no idea what kind of weapons could have been developed by the 32nd Century, and super-weapons with huge destructive potential could exist, even if they have been banned by certain treaties.
Dr Kovich could also be preparing to violate the ban on time travel, travelling back in time to attack Unknown Species 10-C before they have a chance to deploy the DMA. This could lead to us finally getting a bit more detail about how the ban on time travel works!
One final possibility is that Dr Kovich is working on a way to weaponize the Burn – the devastating event that damaged the galaxy in the 31st Century. If a way could be found to use the principles of the Burn to target a specific area, it could be one of the most powerful weapons ever seen in Star Trek – and could be used to try to stop Unknown Species 10-C.
Theory #9: Dr Kovich is involved with the DMA and/or is using the situation to gain power.
Dr Kovich in The Examples.
Thus far, Dr Kovich has been morally ambiguous at worst. In episodes like But To Connect, we even saw how he holds Federation values dear, which could certainly count against him turning out to be a villain. But once again, the mysterious line about having “important things” to do makes me wonder what he’s really up to.
If Dr Kovich is the Vice President, or if he’s a senior figure in an organisation like Section 31, this could all be a power play on his part. He could either be directly involved with the DMA, or else taking advantage of the situation to attempt to gain power for himself. This kind of story could be interesting if it’s well-written, but it would be difficult to pull off turning any Federation leader into an all-out villain!
Theory #10: Dr Kovich is a Q (or Q-like alien).
There are other members of the Q Continuum…
With Q making a return in Picard Season 2, perhaps the Star Trek franchise trying to run two Q stories is out of the question! But something about Dr Kovich again makes me wonder if we could be in for a big surprise. It could be revealed that Dr Kovich is from an alien race and has been observing the Federation while trying to offer limited help and guidance – not dissimilar to how Q operated.
This would certainly be a very big twist! It could even be that the reason for Dr Kovich recusing himself from the mission through the Galactic Barrier was to allow him to contact his people, requesting their help to stop the DMA from destroying Earth and Ni’Var. A long-shot? Maybe…
Theory #11: Bryce is going to die.
Lieutenant Commander Bryce.
Something about Bryce’s goodbye with Saru in the episode The Galactic Barrier – which was a wonderful, very emotional scene – felt incredibly permanent. I’ve since learned that actor Ronnie Rowe Jr. is going to take up a role on Canadian series The Porter, which could mean he’s about to make a permanent exit from Discovery. Bryce could be written out of the show by being transferred to Federation HQ, perhaps, continuing his new role with Dr Kovich. But he also feels like a prime candidate for being killed off.
Given that Bryce isn’t actually on the dangerous mission outside of the galaxy, I’m not sure how he could meet his end. Perhaps an enranged Dr Kovich will kill him if he interferes in his nefarious plans! Or he could be killed by the DMA while trying to evacuate Earth and Ni’Var. There are possibilities – but suffice to say that the likelihood of Bryce surviving the season has dropped dramatically!
Theory #12: Admiral Vance’s holo-message about Earth and Ni’Var was fake or has been tampered with.
Captain Burnham listening to Admiral Vance’s message.
As I said in my review, this is the one part of The Galactic Barrier that I wasn’t wild about. Earth being in trouble is a cliché, and one which really makes the ending of the season feel like an inevitability – with Earth, Titan, Ni’Var, and the rest of the Sol and Vulcan systems in danger, it’s unfathomable that the DMA won’t be stopped in time. But I digress!
If there are other plans afoot at Federation HQ – such as Dr Kovich making a move, for example – it’s plausible to think that someone either faked or tampered with Admiral Vance’s holo-message, meaning that the information Captain Burnham and the crew received wasn’t correct. It could lead to an attempt at a dramatic finale, with Captain Burnham thinking she’s too late to have saved Earth… only to discover that Earth is fine because it was never in danger to begin with!
Theory #13: Oros is still alive – and we’ll see him soon!
Did Oros survive?
Tarka certainly believes that Oros is still alive, and has been working for years to find a way to reach his friend. It would be quite a depressing end to this story if Oros ultimately turned out to have died in that Emerald Chain prison camp years earlier, and a big part of me is rooting for Tarka – despite his flaws.
So is this one a theory or a hope? I guess it’s a mix of both right now! I can think of other ways for Tarka to find a way to cross over to an alternate universe even if he can’t find the DMA’s power source or anything like that to fire up his version of the interdimensional transporter, so there are multiple ways that this theory could pan out.
One alternative, though, would be for Tarka to achieve his goal of leaving this dimension behind… but his destination and Oros’ survival being left ambiguous, similar to what happened with Georgiou in Season 3. This would be less satisfying, at least in my opinion, so I’m keeping my fingers crossed for Tarka to find a way back to Oros!
Theory #14: The Guardian of Forever will be back.
The Guardian of Forever in The Animated Series.
Forget about the interdimensional transporter for a moment. It’s possible that Tarka won’t be able to get it to work or won’t be able to find a sufficient power source to even try. But if that’s the case, there are still ways he could cross the divide between dimensions – and we saw one such method last season.
The Guardian of Forever used its portal to send Georgiou to an alternate reality based on the 23rd Century Mirror Universe in Season 3, and Captain Burnham is aware of the Guardian’s location. If Tarka is unable to find another way, and his plight becomes known to Burnham, perhaps she’ll suggest the Guardian of Forever as an alternative. This would be a great way to bring the Guardian back into the story.
Theory #15: The interdimensional transporter works!
Oros and Tarka with the interdimensional transporter.
While there are other ways for Tarka to reach Oros, the simplest would be for him to get the interdimensional transporter working. Oros may have managed to do so – and I think he probably did, based on what Tarka told Book in The Galactic Barrier – so I’m going to put it out there and say that this piece of technology works, even though it requires a terrific amount of power!
It was implied in The Galactic Barrier that Oros needed the power of an entire planet and a warp core to get it operational, and even then it may have only had enough power for a single one-way trip. But if Oros and Tarka were right in their calculations, using the transporter may be possible, and we could see Tarka use it before the end of the season. Or could we see someone else commandeer the technology…?
Theory #16: Captain Burnham will use the interdimensional transporter to reach Unknown Species 10-C.
Michael Burnham using a transporter in Season 1.
Right now, the stories of the DMA and Tarka’s quest to reach Oros are only tangentially related. But a bigger connection could be made, and there could be a reason why the concept of an interdimensional transporter has suddenly appeared in the story! If Captain Burnham and Discovery arrive at Unknown Species 10-C’s base only to find that the mysterious race inhabit an alternate dimension or parallel universe, perhaps the interdimensional transporter could be the only way to reach them.
This would tie the two sides of the season’s story together, and there could even be a meeting of the minds between Book and Tarka on one side and Captain Burnham on the other, as they realise that they need to work together and share their resources in order for everyone to accomplish their goals. For Tarka, giving up the transporter would be a wrench given everything he’s been through, but having spent time with Book he might be empathetic enough to the plight of Earth and Ni’Var to share it if there are no other options. Alternatively, Captain Burnham could offer to take him to Kayalise using Discovery’s spore drive, or through the aforementioned Guardian of Forever, leading to a trade.
Theory #17: Unknown Species 10-C’s base will be empty or abandoned.
A holographic depiction of the hyperfield.
Connected to the theory above, it’s possible that Unknown Species 10-C may not be native to this universe or this dimension, and their hyperfield may be shielding a base or an area of space that’s uninhabited. The mining operation could be transporting boronite to their native universe, and they could be entirely unaware of the damage they’re doing to sentient races – or they may simply not care.
If this is the case, there are several ways the story could go. The interdimensional transporter could very well come into play as a method of trying to reach Unknown Species 10-C in their native realm, or Captain Burnham could try to figure out a way of shutting down the DMA and/or the hyperfield from this universe.
Theory #18: Michael Burnham won’t remain captain of the USS Discovery.
Burnham in the captain’s chair.
As suggested above, it’s possible that Captain Burnham will have to go to extreme lengths – such as leaving this universe behind – in order to stop the DMA and resolve the conflict with Unknown Species 10-C. If that’s the case, it could set the stage for her departure from the series. I don’t expect Burnham to be killed off, but she could find herself stranded on the wrong side of a one-way portal.
Alternatively, the developing situation between Captain Burnham and Book could end up with her choosing to resign her commission or taking a new job within Starfleet. Her role as captain of Discovery forced her to choose her responsibility to the Federation over her relationship, and after she was almost forced to kill Book, it would be understandable if Captain Burnham never wanted to be put in that position ever again!
Captain Burnham in Stormy Weather.
It wouldn’t be the first time Captain Burnham has been unsure of her place in Starfleet and what role she wants to have. We saw this in Season 3 as part of the background that set up her eventual ascent to the captaincy, and while it seems unlikely that it will come back into play in a big way, the situation with Book could be a catalyst for Captain Burnham wanting to have a simpler life either outside of Starfleet or, at the very least, out of the captain’s chair.
This would also continue a trend that Discovery has had across all four seasons thus far: the rotating captaincy of the ship. Each season has seen a new captain in command, and with Season 5 in the offing, it’s got to be at least possible that this trend will continue. I’m not really in favour of this, but it’s certainly interesting to consider. Because Captain Burnham has been the show’s protagonist since Season 1, it seems unlikely, and the overall arc of Discovery between Season 1 and Season 3 can be read as her redemption and ascent to the captaincy. But the show’s revolving door of captains may continue, and her conflict with Book and the difficult emotional situation it put her in could be the trigger to make this happen.
Theory #19: A major character will be killed off.
A Starfleet coffin in Deep Space Nine.
As mentioned above, if I had to pick one character to bet on to not survive the season, it would have to be Lieutenant Commander Bryce! But with Captain Burnham leading the ship and crew into uncharted, dangerous territory, there’s the possibility of someone else ending up on the chopping block!
Discovery can feel as if it’s providing even its secondary characters with some pretty heavy plot armour sometimes. Dr Pollard in Stormy Weather, Saru and the shuttle crew in Rubicon, and going back to Season 3, Tilly and the bridge crew in That Hope Is You, Part 2 were all in very serious danger – yet they all survived. The departures of Tilly and Gray so far this season have certainly shaken things up – but a well-placed character death could be incredibly impactful.
Theory #20: Kayalise is the Kelvin universe.
The titular USS Kelvin.
Oros didn’t make clear, in the flashback sequences we saw, exactly what Kayalise would be like. He only believed that it would be better than the prime universe, and talked about it in mythological, almost religious terms. That could mean something significant, or it could simply be Oros being poetic!
Tarka had previously suggested that the universe he hopes to escape to is one where the Burn didn’t happen and the Emerald Chain never rose to power. Because of the unique circumstances of the Burn, it seems at least possible that it didn’t occur in the Kelvin timeline – the one established by 2009’s Star Trek. We’ve already had at least one Kelvin reference in Discovery’s 32nd Century, confirming that the universe was known to exist and was reachable. With a fourth Kelvin film in early production, it’s possible that Kayalise is actually the Kelvin universe!
Theory #21: President Rillak knows what the DMA is and may be implicated in its creation.
President Rillak in The Galactic Barrier.
President Rillak’s decision to personally accompany the USS Discovery and Captain Burnham could play into this theory that I’ve been running all season long! I will admit that, as we’ve spent more time with President Rillak she at least appears to be a friendly character, willing to learn from her mistakes and compromise – so that could mean this theory is less likely.
However, as I’ve argued in the past, President Rillak has a manipulative, almost Machiavellian quality. She’s been quite happy to use Captain Burnham to advance positions that it would have been diplomatically or politically difficult for her to do openly – effectively pulling the strings behind the scenes to get a particular outcome that she believes will be favourable to the Federation.
President Rillak at the diplomatic summit.
We’ve also seen President Rillak taking full advantage of the DMA situation – not allowing the crisis to go to waste, to use a contemporary political phrase! The emergence of the DMA arguably accelerated Ni’Var’s Federation membership, and President Rillak even used the diplomatic summit about the DMA to reach out to Earth’s General Ndoye – something that would have been far more difficult had the crisis not brought them together.
None of that necessarily means that President Rillak did all of this on purpose… but she may know more about it than she’s been willing to share thus far, and may have known that the DMA was coming long before it hit Kwejian. It’s possible she has some kind of relationship with Unknown Species 10-C, and travelling with Captain Burnham is a ploy to help her meet them.
Theory #22: The ban on time travel will be explained in more detail.
HMS Bounty travelled back in time in The Voyage Home.
As mentioned above, there may be plans afoot within the Federation and Starfleet to strike Unknown Species 10-C, and a weaponised form of time travel could be a last-resort weapon that the Federation – and other galactic races – might consider using. If so, perhaps the ban on time travel that was introduced in Season 3 will be explained in more detail or expanded upon.
The ban made storytelling sense; it was a way to avoid questions about how the 32nd Century was so different to the far future glimpsed in past iterations of Star Trek, it prevented an easy fix to Georgiou’s health condition, and it prevented any of the main cast returning to the 23rd Century. But it also raised some issues for nitpicking Trekkies like us! The biggest one was how something like this could possibly be enforced; it isn’t possible to un-invent a powerful, weaponisable technology, and even if every single race in the galaxy agreed to the ban in theory, it seems like it would need an incredible level of oversight to enforce it. Finding out more about how the ban works is as much a hope as a theory in some respects, but I think it’s something Discovery should at least attempt to do!
Theory #23: The Federation has flouted the ban on time travel (or is about to).
Book, Burnham, and Sahil with the flag of the Federation in Season 3.
As above, it may be possible that the Federation is about to make a move using time travel to attack Unknown Species 10-C. If so, we may be about to learn that it isn’t the first time that they have failed to abide by the rules set out in the ban on time travel.
It doesn’t seem likely that the DMA is directly related to time travel, as I had previously suggested. But if time travel is about to come into play, we could learn more about the ban and the Federation’s relationship to it.
Theory #24: We haven’t seen the last of the Abronians.
I currently have four ideas for different ways that the Abronians – the non-humanoid race that Captain Burnham, Tilly, and the Qowat Milat helped save from cryo-sleep in the episode Choose To Live – could play a further role in Season 4. Time is ticking away… but it’s still possible!
Theory #24-A: The Abronians’ homeworld was destroyed by the DMA.
Captain Burnham believes this image depicts a “supernova.”
After arriving at the Abronians’ cryo-ship, Captain Burnham found a stone carving that seemed to depict the destruction of the Abronians’ homeworld. This carving was only shown on screen briefly, but it seemed to show the planet being damaged or destroyed in a large explosion. Burnham credited the planet’s destruction to a “supernova,” and the story then raced ahead.
Considering that the main thrust of the season so far has been about the DMA, perhaps Burnham was incorrect: the Abronian homeworld was destroyed by the anomaly, not a supernova.
Theory #24-B: The Abronians’ homeworld was on the other side of the DMA.
Abronian stasis pods.
Now that we know a little more about how the DMA works, this theory seems a little more plausible. Its powerful wormhole technology seems capable of transporting matter over many light-years, meaning it doesn’t seem to be a complete stretch to think that the Abronians may have originated in the vicinity of Unknown Species 10-C. They could even be Unknown Species 10-C!
One thing struck me as odd about the Abronians: the Federation was entirely unaware of them, despite the Abronian cryo-ship being relatively close to Federation space – such that Captain Burnham could reach it using Book’s ship in a short span of time. It’s possible that the Abronians had been asleep for millennia, unnoticed by the Federation and the wider galaxy for all that time. But it’s also at least possible that their cryo-ship is a newcomer to the area. If so, perhaps it arrived here via the DMA.
With Captain Burnham and the crew about to visit the hyperfield, we could be about to find out if the Abronians originated in this region of space.
Theory #24-C: The Abronians will return to help the Federation later in the season.
A deceased Abronian.
One of the themes of Discovery since Season 3 has been connection, including building connections between the Federation and other races and organisations. The Abronians were awoken from cryo-sleep thanks to the interventions of Captain Burnham and Tilly – at least in part – and they may seek to repay the Federation, or Captain Burnham personally, for that help.
We saw this play out last season with Ni’Var; in the season finale Ni’Var ships raced to the Federation’s aid as the Emerald Chain attacked. Perhaps the Abronians will likewise step up to help when the Federation needs allies.
Theory #24-D: The Abronians’ moon-ship may be useful in a later story.
“That’s no moon…”
The cryo-ship used by the Abronians was huge, and appeared to have the mass of a planetoid or small moon. With Earth and Ni’Var now under threat and an evacuation necessary, perhaps the Federation will ask the Abronians to borrow their moon-ship. This could even be what Dr Kovich was planning to do and why he couldn’t join Discovery on the mission through the Galactic Barrier.
The moon-ship was fully operational thanks to the new dilithium that J’Vini “procured,” so it could be commandeered by Starfleet for the purposes of an evacuation. That would be one way to pay off what is, at the moment, a side-story.
Theory #25: Oros built the DMA.
The DMA.
There are similarities in the power generating technology used by the DMA and by Oros’ interdimensional transporter. At the very least, Oros seems capable of creating a power source on that scale, and thus he could be involved with Unknown Species 10-C… for some reason. The question of motive comes up – it doesn’t seem like a good way to attract attention, for example. But it’s possible that an explanation could be found!
Unknown Species 10-C could be native to Kayalise – the universe that Oros hoped to travel to. If so, Oros travelling there could have led to them learning about the prime universe – and that it’s a rich source of yummy boronite! They could have captured Oros, forcing him to build the DMA for them. Or he could have built it voluntarily.
Theory #26: Unknown Species 10-C built the Galactic Barrier.
The USS Discovery approaching the galactic barrier.
Given their technological capabilities, it doesn’t seem impossible that Unknown Species 10-C constructed the Galactic Barrier – perhaps as a way to shield themselves from the races of the Milky Way, or perhaps to keep anyone from exploring too far and discovering their location. There are many reasons why a technologically advanced race might want to build something on this scale – and we could even learn that the harvested boronite is being used to fuel the Galactic Barrier itself.
One possible explanation for why Unknown Species 10-C might want to build something like the Galactic Barrier is to keep the Milky Way’s inhabitants in… but it could also be a shield designed to keep someone else out. That raises a very frightening question: what could be so powerful that a barrier is needed around the entire galaxy? And what could be so dangerous that being locked inside a galaxy with the Borg would be preferable?
With Unknown Species 10-C seemingly being very secretive, I think the idea of them building it to shield themselves is more likely… but there are definitely a lot of ways this theory could go!
Theory #27: Someone else built the Galactic Barrier to keep Unknown Species 10-C out.
The Galactic Barrier.
If the Galactic Barrier is an artificial construct, perhaps it was created by another race or faction as a shield against Unknown Species 10-C. It could be the case that Unknown Species 10-C has used DMA technology against the Milky Way in the distant past, and some other race or faction constructed the Galactic Barrier to keep them out. If Unknown Species 10-C are belligerent and interested in conquest, it might take something on a galactic scale to keep the Milky Way safe. A race like the Q could be responsible if that’s the case.
Obviously this theory and the one above can’t both be right! And it’s a distinct possibility that the Galactic Barrier element of the story is just a convenient macguffin to blind Starfleet to Unknown Species 10-C and prevent easy travel to their region of space, dragging out the story and prolonging attempts at communication so other narrative threads could play out.
If that’s the case, we may learn nothing about the Galactic Barrier in the episodes that lie ahead! However, I still think it’s interesting to consider the possibilities, and it could be fun to finally get some more detail on this lesser-known but significant aspect of the Star Trek galaxy.
Theory #28: Book and Burnham will reconcile and get back together.
Book and Burnham in Rubicon.
We saw a big step toward reconciliation – at least on Book’s part – in Rubicon, when he agreed to stand down and give Burnham and Starfleet a week to attempt to make peaceful first contact and convince Unknown Species 10-C to deactivate the DMA. Book was willing to take a risk by trusting that Burnham would permit him and Tarka to go ahead with their plan at a later time, and even though it didn’t pan out, the way he offered her his trust could open the doorway to reconciliation later on.
I haven’t enjoyed this aspect of the season’s storyline, so this is definitely a hope as much as a theory! But there is a way for Book and Burnham to reach a middle ground, and to find a way to set aside their differences and get back together. As mentioned above, doing so could lead to big changes for both of them – and even for Discovery itself.
Theory #29: Tarka will create his own DMA.
Tarka, Stamets, and Saru with the DMA model.
In The Examples, we saw Tarka – aided by Stamets – building a scale model of the DMA. Now that his plan to destroy it and seize its controller has failed, perhaps he’ll attempt to recreate the device using the knowledge he acquired. If so, he could inadvertently create a new DMA. Or, through time travel shenanigans, Tarka could turn out to be the creator of the original DMA!
If Tarka isn’t able to find a power source for his interdimensional transporter on the far side of the Galactic Barrier, he may feel he has no choice but to try and recreate the DMA’s original power source.
Theory #30: The Red Angel suits from Season 2 are connected to the DMA.
A Red Angel suit in Season 2.
Unknown Species 10-C seem to be responsible for building the DMA… whoever they ultimately turn out to be! But the DMA isn’t the first wormhole-creating technology that Discovery has introduced us to. The Red Angel suits in Season 2 were also capable of creating powerful wormholes… so could it be possible that Unknown Species 10-C built their device around or based on the same technology?
This revelation would greatly affect Captain Burnham, as she’d feel a degree of responsibility even though she wasn’t directly involved. It would also be the second disaster in a row (following the Burn) in which the Federation was implicated – albeit in an oblique way. I’m not convinced that Discovery will go down this route… but the similarities in the wormhole-creating technology gives me pause, at least.
Theory #31: Saru will be given the captaincy of the USS Voyager-J.
Captain Saru in command… of a shuttle!
Saru’s future was briefly discussed before he offered to serve as Captain Burnham’s first officer in the episode Anomaly. He has already been offered a command of his own, so Starfleet clearly values his command abilities and experience. President Rillak was seen to be assessing Captain Burnham’s suitability for the captaincy of the USS Voyager-J in Kobayashi Maru… and she mentioned having a shortlist of candidates. Could Saru be on her list?
Several of the qualities that President Rillak said she was looking for in a potential captain seem to apply to Saru. He’s more level-headed, less likely to put himself in a dangerous situation, and more inclined to think of the big picture. He has a weakness when it comes to Kaminar, as we saw toward the end of Season 3, but generally speaking he isn’t someone who lets his emotions get the better of him. His wisdom and calm demeanour could be valuable in the captain’s chair of the Federation flagship. This could also set the stage for his departure from the show, or possibly even for a new show following his adventures aboard his new ship.
Theory #32: The crew will have to defend the Verubin Nebula.
The dilithium planet is vital to the Federation.
This one is definitely hanging by a thread right now, at least in terms of Season 4! The story continues to unfold in a very different direction, largely ignoring the main story beats from Season 3. But the dilithium shortage has been mentioned more than once, and as things stand right now, the Federation is in control of the galaxy’s only significant dilithium supply. The Verubin Nebula is almost certainly going to be a target for somebody – even if Unknown Species 10-C don’t care about it.
It begins to stretch credulity to think that all of the belligerent factions and races present in the galaxy would become aware of the Federation controlling this impossibly valuable resource and wouldn’t want to take it for themselves. And while it may not happen now until after the DMA storyline has run its course, I think sooner or later someone is going to want to steal the Verubin Nebula and its dilithium. Maybe it will be at the end of Season 4, maybe it will be in Season 5… who knows?
Theory #33: Season 4 will connect with the Short Treks episode Calypso.
Zora dancing with Craft in Calypso.
Zora’s status as a member of the crew was confirmed in But To Connect, and this followed her developing emotions and sentience earlier in the season. Zora is now much closer to her presentation in Calypso, potentially bringing the story of the Short Treks episode one step closer.
There are still significant hurdles to overcome if the story of Calypso is to be wrapped up in Season 4, though. Obviously we have the timeframe issue: will the USS Discovery be sent back in time, be abandoned, or is Calypso taking place centuries in the future? Then we have the USS Discovery itself – it’s been retrofitted since arriving in the 32nd Century, and now looks very different to how it did in Calypso. I’m not sure how Discovery will overcome these hurdles – but it’s possible.
Zora hasn’t had a significant role to play in the last few episodes, but earlier in the season we definitely saw movement in this direction.
Theory #34: There will be a character crossover from a past iteration of Star Trek.
Star Trek has had some wonderful crossovers in the past.
There are many ways to bring back a character from a past iteration of the franchise and incorporate them into the story of Season 4 – and there would be many potential benefits to doing so! I had initially proposed a version of this theory in the run-up to Season 3 that centred on the Doctor from Voyager – but with some creative technobabble, practically anyone could be included, despite the leap forward in time.
Choose To Live showed us the Abronians in cryo-sleep, and Stormy Weather saw the crew of Discovery use the transporter buffer to survive – just like Scotty had done in The Next Generation Season 6 episode Relics. Could these be hints at something to come?
It would also be possible for Captain Burnham to discover the logs or a holographic recording of a long-dead character – and while this would be less of a “crossover,” it could still be a ton of fun and great fan-service!
Theory #35: Some areas of the galaxy – such as the Delta Quadrant – avoided the worst effects of the Burn.
Adira and Stamets with a map of the Milky Way galaxy.
In But To Connect, President Rillak told us that the diplomatic summit she convened would bring together races from “all four” quadrants. Assuming she was referring to the familiar Alpha, Beta, Gamma, and Delta Quadrants that make up the Milky Way galaxy, this would count as our first mention of the Delta Quadrant in the 32nd Century. I didn’t spot any familiar Delta Quadrant races (or their emblems) amongst the assembled delegates, however!
I had previously speculated that the Burn may not have affected the entire galaxy equally, and that regions farthest away from the Verubin Nebula may have survived without much damage. I still think that this is a possibility – though whether Discovery will revisit the Burn in any depth, or visit the Delta Quadrant at all, remains unclear.
Theory #36: Book will find Kyheem and Leto on the other side of the DMA.
Book and Kyheem in Season 3.
In Star Trek: Generations, Captain Picard encountered Captain Kirk inside the Nexus – despite Kirk being declared “dead” after the Enterprise-B encountered the energy ribbon almost eighty years earlier. Now that we know a little more about how the DMA operates, it seems at least faintly possible that, just like Captain Kirk, the inhabitants of Kwejian may not be as dead as they first appear.
This theory is, I freely admit, a bit of a long-shot. But the wormhole technology that we know the DMA uses seems to be capable of sending some of what it harvests or mines back to Unknown Species 10-C’s base of operations. Maybe that means that some of the people from Kwejian were transported there instead of being killed. With Discovery now en route to the hyperfield, perhaps a reunion with Kyheem and Leto is possible!
So that’s the main theory list!
We now have three production-side theories in play, so we’ll look at those too before we wrap things up.
Production-side theory #1: There will be some kind of crossover with Star Trek: Picard Season 2.
Seven of Nine and Admiral Picard.
This theory has arisen in large part because of the very odd scheduling for the next couple of weeks! Picard Season 2 and Discovery Season 4 will run alongside each other for three episodes, and I wonder if that’s because some kind of crossover is on the agenda. With time travel playing a significant role in the story of Picard Season 2, it seems at least plausible to think that some kind of connection is possible!
This could be a complete over-reach, and the ultimate “explanation” for the weird scheduling may turn out to be nothing more than the random illogical spasms of the ineptly-managed Paramount+ and parent company Paramount Global. That would not surprise me in the slightest! But I really do find the scheduling odd.
Picard and Guinan.
The shorter seasons of today’s Star Trek shows means that there really isn’t any need for such a pile-up this spring. Discovery has thirteen episodes, Picard and Strange New Worlds have ten apiece – and even with Lower Decks and Prodigy still to come, there are more than enough weeks in 2022 for the entire Star Trek franchise to be evenly spread out. Why have four out of the next ten weeks with two episodes from two different shows, then a gap of several weeks later in the year where no new Star Trek is broadcast? It makes no sense – especially not on a streaming platform.
Finally, with the constipated international rollout of Paramount+ showing no signs of speeding up, it’s looking increasingly likely that Strange New Worlds will be broadcast in the United States weeks or months ahead of its international premiere. If both Picard Season 2 and Strange New Worlds were delayed by as little as 4-5 weeks, this might be able to be avoided – assuming the rollout of Paramount+ “by the end of Q2” happens as planned.
In short, it’s all very strange – but one possible explanation for the weird scheduling could be that there’s a crossover event planned sometime in the next three weeks!
Production-side theory #2: Tilly’s departure will be permanent.
Tilly’s departure feels permanent.
Mary Wiseman confirmed in an interview with Wil Wheaton on The Ready Room (Discovery’s social media aftershow) that Tilly will be seen again before the end of Season 4, and we glimpsed her in the trailer for the second half of the season as well. But that doesn’t mean she will return as a main character on the show going forward, and her departure in All Is Possible felt permanent. Despite that, I’ve seen quite a lot of folks online who don’t believe that Tilly is actually leaving the series – so I wanted to put it out there officially and say that, in my opinion anyway, she is.
Maybe those people know something that I don’t! As I always say, I don’t have any “insider information;” all of this is just speculation on my part. However, I feel that the manner of Tilly’s departure, the fact that she got that emotional sequence with Captain Burnham, a montage showing her leaving the ship, Adira seeming to take over several of her roles, and her departure feeling like the culmination of her arc going back to the latter part of Season 3 all come together to strongly indicate that she won’t be back as a major character. She may yet have a significant role to play in a future Season 4 episode, as has been suggested, but unless Discovery’s writers are really playing with our emotions I believe we’ve seen Tilly’s end as a main character on the show. She may come back in a future Starfleet Academy series, though… so watch this space!
Production-side theory #3: Season 4 will end on a cliffhanger!
Star Trek has a long, well-established tradition of season-ending cliffhangers! There have been some truly shocking ones in the past, including The Best of Both Worlds in The Next Generation, Deep Space Nine’s Call To Arms, Equinox in Voyager… and many more! With the story of Unknown Species 10-C and the DMA slowly being unpicked, it could be the case that we’ll get a clean resolution – like we did at the end of Season 3. But it’s also possible, in my opinion, that Season 4 will end in similar fashion to Season 2 – on a major cliffhanger!
That could be because the Unknown Species 10-C story didn’t conclude, or a war with the mysterious faction is about to break out. But the Season 4 finale could also set up the beginnings of Season 5’s story, just like how the final moments of Season 1 saw Captain Pike’s Enterprise link up with the USS Discovery.
So that’s it!
The USS Discovery.
As I said, Rosetta didn’t really inspire a lot of new theories, nor did it move the needle in a big way. But with only two episodes left, I think we’re on the precipice of a theory massacre! One way or another, Discovery is running out of time to bring its story to a close… assuming that’s the plan, of course.
I always like to end these theory lists by saying that I do this just for fun. I enjoy writing, I enjoy Star Trek, and spending more time in this world is an escape and an enjoyable distraction. But for some folks, fan theories can be frustrating or unenjoyable, especially if they get very attached to a plausible-sounding theory that ultimately doesn’t pan out. I have no “insider information” and I’m not trying to claim that anything suggested above can, will, or must be part of Discovery Season 4. I fully expect many of these theories to be debunked and for the season to go in wildly unpredictable directions!

Spoiler Warning: There are spoilers ahead for Star Trek: Discovery Seasons 1-4.
Last week’s episode, The Galactic Barrier, was absolutely fantastic – one of the highlights of the season for certain! Unfortunately Rosetta didn’t reach that high bar, and was an episode that felt like it was dragging its feet. While there were some emotional character moments, even those weren’t as strong as they might’ve been and couldn’t salvage an episode in which both halves of the story felt contrived, and where a major new element that had been introduced to the story last week constantly got in the way. Rosetta plodded along, constantly tripping over one big, unnecessary narrative cliché.
I like the idea of Discovery stepping away from total serialisation to go on away missions to planets like the one featured in Rosetta. As we saw just last week – and on a couple of occasions earlier in the season – those semi-standalone stories can work exceptionally well, blending together Discovery’s modern serialised approach to storytelling with at least some components of Star Trek’s episodic past. But this week, for much of the time all I could feel was a sense that the mission to Unknown Species 10-C’s ex-homeworld was a complete waste of time – not only for the characters, who don’t have so much as a second to waste, but more importantly for us as the audience.
The away team.
The worst part of last week’s episode was the insertion of the horribly overused trope of Earth being in danger. I tried to put that to the back of my mind as Rosetta got started, hoping that the time constraint it had imposed would lead to some kind of interesting or exciting storyline as Season 4 reaches its conclusion. But this cliché absolutely ruined Rosetta – turning a story that might’ve had the kernel of a good idea at its core into one that felt like a complete and utter waste of everybody’s time. With time being a very limited resource for Captain Burnham, that just isn’t something that should have been allowed to happen!
If the “Earth is about to be destroyed” cliché wasn’t part of the season’s story, this feeling would have been far less prominent throughout Rosetta, and I could have almost certainly forgiven another detour on the way to Unknown Species 10-C’s hyperfield. With less of a time constraint, such a mission would arguably be worth doing, and while there could still be naysayers and dissenters among the crew and assembled delegates, I would have been firmly in the camp that says “let’s see if we can find any interesting or useful information about this completely unknown faction.” But because Discovery’s writers wanted to crank up the tension and drama to eleven out of ten, what should have been a decent episode with some interesting story elements didn’t work. Instead of the tension rumbling in the background, spurring me on to make the story feel exciting, I could barely prevent myself from shouting at the series to just get on with it – to go to the hyperfield right now! Tension became frustration.
Captain Burnham chose to lead an away mission to a planet instead of racing to the hyperfield.
Not for the first time, narrative contrivances in Discovery have conspired to make Captain Burnham seem like she’s in the wrong. While not exactly being a complete and utter moron, she came across in the episode’s opening act as misguided in the extreme – wasting time on a mission that could have easily yielded nothing of consequence. As happened in episodes like The Vulcan Hello and The Red Angel, it fell to another character to be the voice of reason against Captain Burnham – in this case, Earth’s representative, General Ndoye.
Ndoye made the very simple point that there isn’t time to waste visiting a random planet, and that attempting to make contact first would be the best move. If Unknown Species 10-C didn’t respond to attempts at communication, visiting the planet could be Plan B – but there’s no way it should’ve been Plan A. Rosetta attempts to rely on the away team’s discovery of pheromone-like hydrocarbon dust to say “aha! Captain Burnham was right all along!” but in my view, all that the end of the episode proved was that she got very lucky. Her judgement, four seasons in, is still questionable at times – and on this occasion, with the stakes so very high, I can’t shake the feeling that she made the wrong call.
General Ndoye became the voice of reason… briefly.
The hydrocarbon pheromones will almost certainly play a role in the next couple of episodes – I mean, they have to, right? Otherwise Rosetta will have proven to be a complete waste of time. But even assuming that’s the case, Captain Burnham took a massive risk by diverting to the planet with hours to spare, and it just feels like – not for the first time this season – there was a very easy “middle ground” approach that neither she nor anyone else seems to have considered.
The USS Discovery is equipped with a contingent of shuttles, so sending one with a small away team to the planet while the rest of the crew takes the ship and visits the hyperfield – instead of sitting in orbit of the planet doing fuck all – would have been the hallowed “middle ground” option that the show’s writers seem to have just ignored. Because Captain Burnham has to be the main focus of practically every episode and every major plotline, other characters in the show are relegated to sitting on their hands and waiting for her latest stroke of brilliance. In this case, everyone with the exception of Detmer, Saru, and Dr Culber were just shoved off-screen, seemingly doing nothing except waiting for Captain Burnham to get back. Adira and Reno even found time to get coffee.
This picture is Rosetta in microcosm: Captain Burnham goes off on an away mission while everyone else stands around doing nothing.
That makes Discovery Season 4 feel like a pretty basic story – one designed for small children who don’t have the attention to focus on more than one major narrative at once. Because Captain Burnham wanted to visit the planet, everyone has to visit the planet. God forbid any other character is granted any agency over the plot or given the volition to do anything independently – they’re not real people, you know, just narrative devices.
And yes, it’s Star Trek. It’s fiction. It’s “just a story” – but god do I hate that tired excuse every time it’s trotted out in defence of contrived, underwhelming, or just plain indefensible narratives. If we’re expected to suspend our disbelief and get lost in the world of Star Trek, even just for an hour, the way characters behave has to make basic sense. The characters themselves have to feel like real people – flesh-and-blood beings with emotions, feelings, and brains, not just plot devices who can be used one moment then placed into hibernation the next. And this week, Rosetta basically sidelined the entire crew, forcing them to sit on their hands and do nothing while Captain Burnham took charge of a pretty barebones side-story that I’m not even sure accomplished all that much.
The away team with a cache of magic dust.
I said earlier that the pheromone hydrocarbons will have to feature in the story in some way later on – and I certainly hope that they will! But as of the end of Rosetta, the mission to Unknown Species 10-C’s ex-planet doesn’t feel as though it achieved very much. Captain Burnham didn’t find anything substantial – and the dust, while narratively interesting, was visually unimpressive to say the least. If there had been something more visually unique or interesting about what the away team recovered – like one of the bones that were briefly seen, a computer core, a stone tablet, or literally anything we as the audience could see, maybe that feeling wouldn’t be so prevalent. But because even the away mission’s big accomplishment was difficult to really perceive, the entire story feels like it’s on far shakier ground than it already was.
If the pheromone hydrocarbons are incorporated into the story of the next couple of episodes in a major way, maybe we’ll revisit Rosetta and consider it a little more favourably in hindsight. There are definitely interesting possibilities with this new narrative element that could be explored or that could be paid off in a big way. But if Discovery doesn’t do something big with the pheromone hydrocarbons before the end of the season, the episode will feel like even more of a waste than it already does.
Will the pheromone dust play a significant enough role in the story to make Rosetta feel like a worthwhile detour?
In past iterations of Star Trek – including in previous episodes and seasons of Discovery – the universal translator has been shown to work pretty well. There are some exceptions – such as the Tamarians – but even then a way across the language barrier was eventually found. With the 900-year time jump to the 32nd Century, it stands to reason that the universal translator has only gotten better as Starfleet has encountered more and more races. Even if we accept the premise that communication has never been successfully made with a species that uses pheromones or chemicals to communicate, doesn’t it seem like it would be worth trying to use the universal translator, especially given the time constraints? With the level of technology that Unknown Species 10-C has been shown to have, they might have some kind of translator or communicator of their own, too.
I know a lot of this must sound like nitpicking, but it all stems from the fact that the show’s writers chose to inject forced drama by using an “Earth is in danger and there’s just hours to save it!” cliché that wasn’t necessary to make this story interesting or exciting. The stakes were high enough, the danger was real enough, and by trying to turn the drama up to eleven, Rosetta tripped over. There was a potentially interesting story about learning more about a very new and different form of life… but it’s one that this cliché has spoiled. Take away the time constraint and many of the narrative complaints on this side of the story would have fallen away.
A holographic depiction of the hyperfield.
Rosetta wasn’t saved by its B-plot, either, with Tarka and Book undertaking an equally nonsensical away mission that also seemed to be based on a very shaky premise. With Captain Burnham’s decision to take an away mission to the planet, my criticism stems from the fact that The Galactic Barrier had introduced the cliché of Earth being threatened meaning that there wasn’t time for a detour. But Book and Tarka’s away mission to the USS Discovery was done because they… wanted to stick Book’s ship to Discovery’s hull? Couldn’t they just remain under cloak and tail the ship? It feels pretty weak, even by the standards of Star Trek technobabble.
We also didn’t get to see any of Book and Tarka’s journey navigating the Galactic Barrier, which is something I was genuinely interested in. A powerful ship like the USS Discovery barely made it through, so how would Book’s glorified runabout survive? We basically got no payoff to Book and Tarka’s side-mission last week of collecting programmable antimatter at the abandoned prison camp. Presumably they were able to successfully apply it and transit the Galactic Barrier – but the episode literally didn’t even pay lip service to that, with their story starting up with Book’s ship already parked a few yards away from the USS Discovery.
Couldn’t Book and Tarka just continue to tail Discovery? Also, how did they make it through the Galactic Barrier?
Given how difficult navigating the Galactic Barrier proved to be for the USS Discovery, it’s a shame that we didn’t get to see Book and Tarka having to tackle that task. Maybe it could’ve been included at the end of last week’s episode – even if it was just a short sequence, Discovery should really have done something to pay off their mission to the prison camp.
It also seems like Book has decided that he and Tarka are fugitives without even trying to make contact and explain what happened. The end of Rubicon suggested that there might be a pathway to reconciliation for him and Michael, but he has done nothing to attempt to pursue that – except for creepily spying on her in what has to be one of the most uncomfortable moments in the entire episode. Book signalled his willingness to stand down and give peace a chance; it was only Tarka’s actions that led to the weapon being detonated. With Captain Burnham on his side to advocate for him, you’d think he’d know that he has a good chance of not getting into serious trouble – and he could even be a valuable asset to Starfleet, sharing his knowledge of Tarka and his plans.
Did anyone else find this moment of Book spying on Burnham a little creepy? Cool camera shot, though…
This continues a trend of Book having been fairly static for several episodes now, having gone through several stages of grief for Kwejian and his family before seeming to just… stop. In the first half of the season, Book got some of the most deeply emotional moments in the show, and seeing how grief was leading him down a dark path was a potentially interesting story, but it’s one that Discovery hasn’t really been able to successfully elaborate on. Like most of the rest of the characters, Book has been relegated to a supporting role, and that means he doesn’t really get much agency over the story any more. He’s stuck following Tarka just like everyone else is stuck following Burnham. If we’d heard anything from him to indicate that he was still committed to that cause, maybe it wouldn’t feel so silly. But right now, Book feels like a follower; a passive character caught in Tarka’s narrative wake.
So I’m not going to nitpick things like needing to physically board the ship to install a macguffin into the macguffin network. That’s Star Trek-ish enough to be inoffensive. But the setup that led Book and Tarka to that point felt very contrived, and it wasn’t sufficiently explained as to why they couldn’t just continue to tail Discovery all the way to – and perhaps inside – the hyperfield. It also wasn’t explained why everyone keeps assuming that the hyperfield will be impenetrable – they haven’t even tried to approach it, and if Unknown Species 10-C are as advanced as we think they are, surely they’d see a spaceship coming and investigate. Book and Tarka’s quest this week seems like an unnecessarily involved stealth mission that had the potential to lead to moments of either extreme drama or perhaps even comedy, with the two fugitives sneaking on board the ship, but it ultimately didn’t deliver much of either.
Book and Tarka managed to sneak aboard Discovery.
Bringing General Ndoye into the Book-Tarka side of the story is, again, something that we’ll have to watch and see whether it leads to a significant payoff. Right now it feels like it could go either way, and although I would argue that Ndoye had been the voice of reason earlier in the episode with Captain Burnham, I’m not wild about her becoming a kind of double-agent in this conspiracy.
Two of the big thematic elements of Seasons 3 and 4 have been connection and communication – and it seems like the series is now building to a conclusion which will say something like “if only Book and Tarka had worked with Captain Burnham, everyone could have got what they wanted.” If Book and Tarka would share why Tarka wants the power source, maybe Captain Burnham could work with him – or find an alternative way for him to travel between universes, such as the Guardian of Forever that we saw last season. And if Captain Burnham could find a way to compromise with Book, their whole relationship feud could be solved. A story about how division and failing to communicate can lead to problems can be a powerful one, but it’ll need to be executed a damn sight better than it was in Rosetta. Here, the two disconnected stories just chafed against each other in the most frustrating way.

The CGI work for Unknown Species 10-C’s planet was good, and although it was only seen very briefly and not really explained, I liked the “Dyson rings” seen orbiting their star. Presumably Discovery scanned the rings off-screen and determined there’s nothing worth looking for there… although that would have been nice to get confirmation of, otherwise the rings seem a good target for an away mission of this nature as well.
The filming location for the outdoor sections of the away mission looked very familiar; I’m sure it was seen either earlier in Season 4 or perhaps in Season 3. In an interview for The Ready Room a few weeks ago, Mary Wiseman mentioned a quarry in the Toronto area that has been used for several outdoor shoots, which could be why it’s so familiar. Slapping a yellow filter on it in post-production didn’t really do much to disguise it, and with the new AR wall that Paramount invested a fair amount of money in, I’m left wondering why the Star Trek franchise keeps walking headfirst into this particular mistake. The AR wall was used to great effect to depict the interior of the Unknown Species 10-C base… so why not the exterior as well?
The away team.
The crew’s EV suit malfunction is also a bit of a contrivance. Aren’t protective suits meant to protect against everything in the environment, especially things that are new or haven’t been encountered before? This is another nitpick, I guess, but I didn’t like the way that this was just hand-waved away by half a line of dialogue. “Oh, I guess the EV suits don’t protect against substances that aren’t in the Federation database and are very different.” That just seems like an odd way to explain it. And if we want to keep nitpicking, that dust looked like it was everywhere – floating in the air as well as lying on the ground and on surfaces. So how did Detmer not get exposed when everyone else did?
After making the decision to waste time on an away mission that, realistically, she must’ve known had the possibility of failure, Captain Burnham came across as incredibly stubborn shortly before the crew encountered the 10-C nursery. Partly this was triggered by a reaction to the hydrocarbons, I guess, but coming after I found her decision to go on the mission in the first place difficult to justify, stubbornly doubling-down on it when it seemed as though there wasn’t anything to find wasn’t a great look for her character.

So have we just nitpicked Rosetta to death?
There were interesting and clever concepts buried here, and there were some nice but unspectacular character moments between Dr Culber and Captain Burnham, Tarka and Book, and to a lesser extent between Reno and Adira and Detmer and Adira too. Some fans argue that Discovery is all about its characters and that the sci-fi trappings should just be seen as a backdrop, with any contrivances and plot complaints waved away because of how well-done some of these character moments can be. I don’t agree with that – if you want character drama, go and watch a soap or some scripted reality show. Star Trek is science fiction, so at the very least the sci-fi side of the story has to be basically competent and good enough to keep my suspension of disbelief going.
Because of how Rosetta sidelined many of the other characters and didn’t actually spend that much time on these interpersonal moments, I would argue that it wasn’t even a particularly impressive episode on the character side of things, either. The moment between Dr Culber and Captain Burnham came in two parts – one during the away mission and one at the end in her ready-room. But it lasted all of two minutes, maybe, and that just isn’t enough time to do justice to a complicated mental health story.
Counselling for the counsellor.
Dr Culber’s storyline feels like it’s retreading the Detmer path from Season 3. We’ve had a few short scenes spread across a handful of episodes to explain in the most basic of ways how he feels overwhelmed, stressed, and/or unable to cope with his work and the situation he’s found himself in. His moment admitting to Captain Burnham that he isn’t okay should have been the culmination of this season-long character arc… but it’s an arc that feels so underdeveloped that, despite the beautiful performance by Wilson Cruz, I’m struggling to buy it. The story of a counsellor – someone working as a mental health professional – needing to seek help for their own struggles is a noble one, and one absolutely worth telling, but it’s also a story that Discovery is not doing justice to as things stand.
I’ve been a big advocate for better mental health representation in all forms of media, but I’m unfortunately in the position of having to say that if the series can’t do justice to stories like this I’d honestly rather that it skipped them altogether. It feels like Discovery is doing little more than paying lip service to a serious topic, one that’s clearly too big for the limited time and attention that the show is willing to dedicate to it.
Captain Burnham and Dr Culber during the away mission.
Returning to Detmer, last season she got a storyline about post-traumatic stress that was referenced in Rosetta. But like Dr Culber’s story of dealing with his struggles this season, it wasn’t fleshed out enough to be meaningful. She had a few scenes spread across a handful of episodes, then seemed to magically “get better.” It’s only now, a full season later, that we even heard about her getting help or treatment for PTSD.
In Rosetta, Discovery also continued a disappointing trend of ham-fistedly inserting blatantly expository dialogue that the writers sometimes use as a substitute for actual character development. In this case, Detmer remembered something about her father mistreating her that could have been significant, but it was treated as an afterthought by a script that had its attention firmly focused elsewhere. Emily Coutts did well with the material she had, and put in a decent performance – but the material was barebones to say the least.
Lieutenant Commander Detmer.
Saru’s panic attack was one of the more interesting moments of characterisation, and if I were to single out one performance and one strong element from Rosetta it would be the way Doug Jones conveyed Saru’s terror during these sequences. We’ll have to set aside questions of why Captain Burnham didn’t immediately send him back to the shuttle, but if we can ignore contrivances like that, Saru really sold me on his panic attack. As someone who has had panic attacks myself – thankfully infrequently – I found the depiction of Saru in these moments very relatable.
We got a bit of a pep talk between Reno and Adira; two characters who don’t feel like a natural pair but who worked well together this time. Adira has adopted much of the awkwardness of Season 1 Tilly, and that “young, inexperienced, and nervous” character type is a good counterbalance to some of the show’s older and more established characters. Reno was deadpan as ever, but none of her lines this week were laugh-out-loud funny; while her scenes brought some much-needed levity to the story, they didn’t exactly blow me away.
Reno with Adira.
Finally, we come to Dr Hirai. For the second episode running – and he’s only been in two episodes so far – he felt very underused. There was a brief scene between him and President Rillak in which she rebuked him for his bluntness, but that was it. Perhaps that was deserved, but as we’ve spent such a minuscule amount of time with this character, it just felt like an unnecessary addition. If Dr Hirai was going to be featured in a scene this week, why not show him working or doing something that could contribute to the story? Just because everyone aboard Discovery was sitting around waiting for Burnham to get back that doesn’t mean he couldn’t have found something useful to do.
Again, Dr Hirai is someone who could have a bigger role to play before the season ends. But his two appearances so far in Rosetta and in The Galactic Barrier have felt like fluff; a potentially-interesting character about whom we know nothing of consequence. If he is going to have something significant to do in the next couple of episodes, we need to start seeing more from him very soon – otherwise he risks feeling rather flat.
Dr Hirai.
So that was Rosetta, I guess. Not the season’s high-water mark, unfortunately.
At the core of the episode there was an interesting idea, and the notion of Unknown Species 10-C being difficult to communicate with is a concept that could still work – if it’s properly executed in the two episodes that remain. But because The Galactic Barrier added an unnecessary time constraint to Captain Burnham’s mission, this side-quest felt more frustrating than exciting; I wanted to shout at Captain Burnham – and at Discovery’s writers – to just get on with the main story.
There were more than enough smaller narrative threads to pick at to unravel the episode’s entire story. Both the A- and B-plots were disappointing, and even where Discovery has been successful in the past – with moments of characterisation and communication – I was underwhelmed by what Rosetta had to offer. As we approach the final two episodes of the season, there’s a lot of work left to do to pull out a decent ending to this rather plodding story.

Spoiler Warning: There are spoilers ahead for Star Trek: Discovery Seasons 1-4, Star Trek: Picard Season 1 and the trailers and teasers for Season 2, and for other iterations of the Star Trek franchise.
Well, that was unexpected! I wrote last week that I expected the theory list to continue to thin out as we edge closer to the end of Season 4, but this week’s episode, The Galactic Barrier, has actually provided several new theories while only debunking one existing one. I really enjoyed what The Galactic Barrier had to offer. Its semi-standalone adventure took Captain Burnham and the USS Discovery to the outer edge of the galaxy, while still finding time for Book and Tarka to explore the latter’s mysterious past.
I’ll be happy to return to The Galactic Barrier when the season is over and enjoy its dangerous adventure storyline for the sci-fi fun that it was. There were still plenty of smaller character moments – the developing relationship between T’Rina and Saru, for example, is incredibly sweet – but overall, I think I’ll remember the episode for its mission through the titular Galactic Barrier. And for the many new theories that it kick-started for me!
Let’s start with the theory that’s been debunked before we jump into the main list.
Debunked theory: Tarka’s mysterious friend is a character we’ve already met.
As I said in my review of The Galactic Barrier, I like Oros as a character and his relationship with Tarka seems very sweet. But the way we arrived at that moment was rather odd, and almost feels like it was designed to be an unsatisfying end to an unnecessary mystery.
Think about it like this: what would have changed in But To Connect if Tarka had named his friend when Book asked? Absolutely nothing about this storyline would have been any different in any of the four episodes in which it featured if we’d known from the start that the character’s name was Oros. Keeping the name hidden was a deliberate choice by Discovery’s writers… but it’s one that didn’t add anything to the mystery while encouraging speculation like this. And because that speculation ultimately went nowhere, there’s now a slightly underwhelming edge to what should’ve been a perfectly fine storyline.
Tarka’s friend: Oros.
I always caveat all of my theories by saying that they’re unlikely to pan out, and that they aren’t worth getting too invested in or worked up over. And to be fair, I said from the start that Tarka’s friend being a familiar character felt like somewhat of a long-shot. But the way in which this storyline was written and dragged out across But To Connect, All In, and Rubicon seems like it was designed to conceal something incredibly basic – Oros’ name – that just didn’t need to be concealed.
As Trekkies, we like to speculate and theorise, and in this case the reveal of Oros as a new character is slightly less fun than it should’ve been because of how it was set up. All it would’ve taken to avoid that was Oros’ name being dropped in But To Connect.
So that theory was debunked!
We have no confirmations this week, so now we’ll get into the main theory list, beginning with those theories that were new or saw movement in The Galactic Barrier.
Theory #1: Dr Kovich works for Section 31.
Dr Kovich in The Galactic Barrier.
I struck this theory off the list a few weeks ago, when it seemed like Dr Kovich’s role was a more conventional one within the hierarchy of the Federation. But it’s back this week because of his mysterious behaviour!
Section 31 is the Federation’s off-the-books black ops organisation, and with Dr Kovich seeming to occupy a powerful position, it makes sense that he could be running it – or a senior figure within it. I’m not sure at this stage whether his line about having something more important to do will actually be paid off in a significant way; it felt like one of those seemingly-important lines that Discovery sometimes throws out only for it to come to naught in the end. But if Dr Kovich is going to have a significant role to play later on, perhaps we’ll finally learn exactly who he is and why he’s so influential.
If Dr Kovich is involved with Section 31 – or a similar organisation – we arguably saw hints as far back as his first appearance in Season 3. The way that he debriefed Georgiou, and later declined to reveal her impending health condition until after it manifested, could indicate that Dr Kovich is rather cold and calculating – traits we would associate with Section 31.
Theory #2: Dr Kovich is the Federation Vice President.
If there’s a President there must also be a Vice President, and in The Galactic Barrier we got confirmation of this when President Rillak stated her intention to transfer power to the VP while she was away. As above with Tarka’s friend, the name of the Vice President was kept deliberately hidden during the conversation between Rillak and Admiral Vance, which could mean nothing – or it could mean we’re set for a revelation later on!
There aren’t any other named characters – or even background characters – that we’ve seen with President Rillak or around Federation HQ who could be the Vice President, so unless it’s a brand-new character – which is definitely a serious possibility – Dr Kovich is pretty much the only candidate I can think of! It’s possible that this character won’t have any bearing on the rest of the season and was just mentioned in dialogue, but it’s also possible that the VP will have to take significant decisions in the President’s absence.
Theory #3: Dr Kovich is preparing a weapon of last resort to strike Unknown Species 10-C.
The meeting at which Dr Kovich revealed he has other things to do.
What could be more important than making peaceful first contact with an advanced alien race who have the power to destroy entire planets? No one at the meeting seemed to know – or at least chose not to speculate out loud. One possibility that I can think of, though, is that Dr Kovich is putting contingency plans in place to attack Unknown Species 10-C in the event that President Rillak and Captain Burnham fail in their mission.
With Earth and Ni’Var – two of the Federation’s founding worlds – now under direct threat, the time may have come to step up plans for a major attack. This could take the form of a preventative strike, designed to stop Unknown Species 10-C or dissuade them from continuing with the DMA, or it could be a “weapon of last resort,” designed to retaliate in the event that Earth and Ni’Var are destroyed.
Tarka’s isolytic weapon.
If Dr Kovich is involved with an organisation like Section 31, the possibilities for weapons are almost unlimited – we have no idea what kind of weapons could have been developed by the 32nd Century, and super-weapons with huge destructive potential could exist, even if they have been banned by certain treaties.
Dr Kovich could also be preparing to violate the ban on time travel, travelling back in time to attack Unknown Species 10-C before they have a chance to deploy the DMA. This could lead to us finally getting a bit more detail about how the ban on time travel works!
One final possibility is that Dr Kovich is working on a way to weaponize the Burn – the devastating event that damaged the galaxy in the 31st Century. If a way could be found to use the principles of the Burn to target a specific area, it could be one of the most powerful weapons ever seen in Star Trek – and could be used to try to stop Unknown Species 10-C.
Theory #4: Dr Kovich is involved with the DMA and/or is using the situation to gain power.
Dr Kovich in The Examples.
Thus far, Dr Kovich has been morally ambiguous at worst. In episodes like But To Connect, we even saw how he holds Federation values dear, which could certainly count against him turning out to be a villain. But once again, the mysterious line about having “important things” to do makes me wonder what he’s really up to.
If Dr Kovich is the Vice President, or if he’s a senior figure in an organisation like Section 31, this could all be a power play on his part. He could either be directly involved with the DMA, or else taking advantage of the situation to attempt to gain power for himself. This kind of story could be interesting if it’s well-written, but it would be difficult to pull off turning any Federation leader into an all-out villain!
Theory #5: Dr Kovich is a Q (or Q-like alien).
There are other members of the Q Continuum…
With Q making a return in Picard Season 2 (which also kicks off this week), perhaps the Star Trek franchise trying to run two Q stories is out of the question! But something about Dr Kovich again makes me wonder if we could be in for a big surprise. It could be revealed that Dr Kovich is from an alien race and has been observing the Federation while trying to offer limited help and guidance – not dissimilar to how Q operated.
This would certainly be a very big twist! It could even be that the reason for Dr Kovich recusing himself from the mission through the Galactic Barrier was to allow him to contact his people, requesting their help to stop the DMA from destroying Earth and Ni’Var. A long-shot? Maybe…
Theory #6: Bryce is going to die.
Lieutenant Commander Bryce.
Something about Bryce’s goodbye with Saru – a wonderful, very emotional scene – felt incredibly permanent. I’ve since learned that actor Ronnie Rowe Jr. is going to take up a role on Canadian series The Porter, which could mean he’s about to make a permanent exit from Discovery. Bryce could be written out of the show by being transferred to Federation HQ, perhaps, continuing his new role with Dr Kovich. But he also feels like a prime candidate for being killed off.
Given that Bryce isn’t actually on the dangerous mission outside of the galaxy, I’m not sure how he could meet his end. Perhaps an enranged Dr Kovich will kill him if he interferes in his nefarious plans! Or he could be killed by the DMA while trying to evacuate Earth and Ni’Var. There are possibilities – but suffice to say that the likelihood of Bryce surviving the season just dropped dramatically!
Theory #7: Admiral Vance’s holo-message about Earth and Ni’Var was fake or has been tampered with.
Captain Burnham listening to Admiral Vance’s message.
As I said in my review, this is the one part of The Galactic Barrier that I wasn’t wild about. Earth being in trouble is a cliché, and one which really makes the ending of the season feel like an inevitability – with Earth, Titan, Ni’Var, and the rest of the Sol and Vulcan systems in danger, it’s unfathomable that the DMA won’t be stopped in time. But I digress!
If there are other plans afoot at Federation HQ – such as Dr Kovich making a move, for example – it’s plausible to think that someone either faked or tampered with Admiral Vance’s holo-message, meaning that the information Captain Burnham and the crew received wasn’t correct. It could lead to an attempt at a dramatic finale, with Captain Burnham thinking she’s too late to have saved Earth… only to discover that Earth is fine because it was never in danger to begin with!
Theory #8: Book and Tarka will successfully cross the Galactic Barrier.
Tarka and Book in Rubicon.
This one feels like an inevitability – Book and Tarka are clearly building up to making their own attempt to cross the Barrier in the next episode. If Captain Burnham and Discovery get into trouble, Book and Tarka could arrive at the last minute to help out.
After going to all the trouble of locating programmable antimatter for Book’s ship this week, I’d be shocked if Book and Tarka didn’t immediately deploy it and find their own way across the Galactic Barrier.
Theory #9: Oros is still alive – and we’ll see him soon!
Did Oros survive?
Tarka certainly believes that Oros is still alive, and has been working for years to find a way to reach his friend. It would be quite a depressing end to this story if Oros ultimately turned out to have died in that Emerald Chain prison camp years earlier, and a big part of me is rooting for Tarka – despite his flaws.
So is this one a theory or a hope? I guess it’s a mix of both right now! I can think of other ways for Tarka to find a way to cross over to an alternate universe even if he can’t find the DMA’s power source or anything like that to fire up his version of the interdimensional transporter, so there are multiple ways that this theory could pan out.
One alternative, though, would be for Tarka to achieve his goal of leaving this dimension behind… but his destination and Oros’ survival being left ambiguous, similar to what happened with Georgiou in Season 3. This would be less satisfying, at least in my opinion, so I’m keeping my fingers crossed for Tarka to find a way back to Oros!
Theory #10: The Guardian of Forever will be back.
The Guardian of Forever in The Original Series.
Forget about the interdimensional transporter for a moment. It’s possible that Tarka won’t be able to get it to work or won’t be able to find a sufficient power source to even try. But if that’s the case, there are still ways he could cross the divide between dimensions – and we saw one such method last season.
The Guardian of Forever used its portal to send Georgiou to an alternate reality based on the 23rd Century Mirror Universe in Season 3, and Captain Burnham is aware of the Guardian’s location. If Tarka is unable to find another way, and his plight becomes known to Burnham, perhaps she’ll suggest the Guardian of Forever as an alternative. This would be a great way to bring the Guardian back into the story.
Theory #11: The interdimensional transporter works!
Oros and Tarka with the interdimensional transporter.
While there are other ways for Tarka to reach Oros, the simplest would be for him to get the interdimensional transporter working. Oros may have managed to do so – and I think he probably did, based on what Tarka told Book in The Galactic Barrier – so I’m going to put it out there and say that this piece of technology works, even though it requires a terrific amount of power!
It was implied in The Galactic Barrier that Oros needed the power of an entire planet and a warp core to get it operational, and even then it may have only had enough power for a single one-way trip. But if Oros and Tarka were right in their calculations, using the transporter may be possible, and we could see Tarka use it before the end of the season. Or could we see someone else commandeer the technology…?
Theory #12: Captain Burnham will use the interdimensional transporter to reach Unknown Species 10-C.
Michael Burnham using a transporter in Season 1.
Right now, the stories of the DMA and Tarka’s quest to reach Oros are only tangentially related. But a bigger connection could be made, and there could be a reason why the concept of an interdimensional transporter has suddenly appeared in the story! If Captain Burnham and Discovery arrive at Unknown Species 10-C’s base only to find that the mysterious race inhabit an alternate dimension or parallel universe, perhaps the interdimensional transporter could be the only way to reach them.
This would tie the two sides of the season’s story together, and there could even be a meeting of the minds between Book and Tarka on one side and Captain Burnham on the other, as they realise that they need to work together and share their resources in order for everyone to accomplish their goals. For Tarka, giving up the transporter would be a wrench given everything he’s been through, but having spent time with Book he might be empathetic enough to the plight of Earth and Ni’Var to share it if there are no other options. Alternatively, Captain Burnham could offer to take him to Kayalise using Discovery’s spore drive, or through the aforementioned Guardian of Forever, leading to a trade.
Theory #13: Unknown Species 10-C’s base will be empty or abandoned.
A holographic depiction of the hyperfield.
Connected to the theory above, it’s possible that Unknown Species 10-C may not be native to this universe or this dimension, and their hyperfield may be shielding a base or an area of space that’s uninhabited. The mining operation could be transporting boronite to their native universe, and they could be entirely unaware of the damage they’re doing to sentient races – or they may simply not care.
If this is the case, there are several ways the story could go. The interdimensional transporter could very well come into play as a method of trying to reach Unknown Species 10-C in their native realm, or Captain Burnham could try to figure out a way of shutting down the DMA and/or the hyperfield from this universe.
Theory #14: Unknown Species 10-C is extinct.
Rest in peace, Unknown Species 10-C…
Connected to the theory above, rather than simply their mining base being abandoned, Unknown Species 10-C may have already gone extinct. The DMA might represent a last-ditch attempt to save themselves from that fate, and the story could proceed in a similar fashion to The Doomsday Machine, in which the planet-killer was an automated system roaming the galaxy long after its creators disappeared.
There could be an interesting environmental message if such a story were to play out: the impact we have on the environment with things like carbon emissions, climate change, and so on will continue to resonate long after we’re gone. Some of these problems will fall to future generations to solve – and perhaps this time, that task will fall to Captain Burnham.
Theory #15: Michael Burnham won’t remain captain of the USS Discovery.
Burnham in the captain’s chair.
As suggested above, it’s possible that Captain Burnham will have to go to extreme lengths – such as leaving this universe behind – in order to stop the DMA and resolve the conflict with Unknown Species 10-C. If that’s the case, it could set the stage for her departure from the series. I don’t expect Burnham to be killed off, but she could find herself stranded on the wrong side of a one-way portal.
Alternatively, the developing situation between Captain Burnham and Book could end up with her choosing to resign her commission or taking a new job within Starfleet. Her role as captain of Discovery forced her to choose her responsibility to the Federation over her relationship, and after she was almost forced to kill Book, it would be understandable if Captain Burnham never wanted to be put in that position ever again!
Captain Burnham in Stormy Weather.
It wouldn’t be the first time Captain Burnham has been unsure of her place in Starfleet and what role she wants to have. We saw this in Season 3 as part of the background that set up her eventual ascent to the captaincy, and while it seems unlikely that it will come back into play in a big way, the situation with Book could be a catalyst for Captain Burnham wanting to have a simpler life either outside of Starfleet or, at the very least, out of the captain’s chair.
This would also continue a trend that Discovery has had across all four seasons thus far: the rotating captaincy of the ship. Each season has seen a new captain in command, and with Season 5 in the offing, it’s got to be at least possible that this trend will continue. I’m not really in favour of this, but it’s certainly interesting to consider. Because Captain Burnham has been the show’s protagonist since Season 1, it seems unlikely, and the overall arc of Discovery between Season 1 and Season 3 can be read as her redemption and ascent to the captaincy. But the show’s revolving door of captains may continue, and her conflict with Book and the difficult emotional situation it put her in could be the trigger to make this happen.
Theory #16: A major character will be killed off.
A Starfleet funeral seen in Lower Decks.
As mentioned above, if I had to pick one character to bet on to not survive the season, it would have to be Lieutenant Commander Bryce! But with Captain Burnham leading the ship and crew into uncharted, dangerous territory, there’s the possibility of someone else ending up on the chopping block!
Discovery can feel as if it’s providing even its secondary characters with some pretty heavy plot armour sometimes. Dr Pollard in Stormy Weather, Saru and the shuttle crew in Rubicon, and going back to Season 3, Tilly and the bridge crew in That Hope Is You, Part 2 were all in very serious danger – yet they all survived. The departures of Tilly and Gray so far this season have certainly shaken things up – but a well-placed character death could be incredibly impactful.
Theory #17: Kayalise is the Kelvin universe.
The titular USS Kelvin.
Oros didn’t make clear, in the flashback sequences we saw, exactly what Kayalise would be like. He only believed that it would be better than the prime universe, and talked about it in mythological, almost religious terms. That could mean something significant, or it could simply be Oros being poetic!
Tarka had previously suggested that the universe he hopes to escape to is one where the Burn didn’t happen and the Emerald Chain never rose to power. Because of the unique circumstances of the Burn, it seems at least possible that it didn’t occur in the Kelvin timeline – the one established by 2009’s Star Trek. We’ve already had at least one Kelvin reference in Discovery’s 32nd Century, confirming that the universe was known to exist and was reachable. With a fourth Kelvin film in early production, it’s possible that Kayalise is actually the Kelvin universe!
Theory #18: President Rillak knows what the DMA is and may be implicated in its creation.
President Rillak in The Galactic Barrier.
President Rillak’s decision to personally accompany the USS Discovery and Captain Burnham could play into this theory that I’ve been running all season long! I will admit that, as we’ve spent more time with President Rillak she at least appears to be a friendly character, willing to learn from her mistakes and compromise – so that could mean this theory is less likely.
However, as I’ve argued in the past, President Rillak has a manipulative, almost Machiavellian quality. She’s been quite happy to use Captain Burnham to advance positions that it would have been diplomatically or politically difficult for her to do openly – effectively pulling the strings behind the scenes to get a particular outcome that she believes will be favourable to the Federation.
President Rillak at the diplomatic summit.
We’ve also seen President Rillak taking full advantage of the DMA situation – not allowing the crisis to go to waste, to use a contemporary political phrase! The emergence of the DMA arguably accelerated Ni’Var’s Federation membership, and President Rillak even used the diplomatic summit about the DMA to reach out to Earth’s General Ndoye – something that would have been far more difficult had the crisis not brought them together.
None of that necessarily means that President Rillak did all of this on purpose… but she may know more about it than she’s been willing to share thus far, and may have known that the DMA was coming long before it hit Kwejian. It’s possible she has some kind of relationship with Unknown Species 10-C, and travelling with Captain Burnham is a ploy to help her meet them.
Theory #19: The ban on time travel will be explained in more detail.
La Sirena may be about to travel through time in Picard Season 2…
As mentioned above, there may be plans afoot within the Federation and Starfleet to strike Unknown Species 10-C, and a weaponised form of time travel could be a last-resort weapon that the Federation – and other galactic races – might consider using. If so, perhaps the ban on time travel that was introduced in Season 3 will be explained in more detail or expanded upon.
The ban made storytelling sense; it was a way to avoid questions about how the 32nd Century was so different to the far future glimpsed in past iterations of Star Trek, it prevented an easy fix to Georgiou’s health condition, and it prevented any of the main cast returning to the 23rd Century. But it also raised some issues for nitpicking Trekkies like us! The biggest one was how something like this could possibly be enforced; it isn’t possible to un-invent a powerful, weaponisable technology, and even if every single race in the galaxy agreed to the ban in theory, it seems like it would need an incredible level of oversight to enforce it. Finding out more about how the ban works is as much a hope as a theory in some respects, but I think it’s something Discovery should at least attempt to do!
Theory #20: The Federation has flouted the ban on time travel (or is about to).
Book, Burnham, and Sahil with the flag of the Federation in Season 3.
As above, it may be possible that the Federation is about to make a move using time travel to attack Unknown Species 10-C. If so, we may be about to learn that it isn’t the first time that they have failed to abide by the rules set out in the ban on time travel.
It doesn’t seem likely that the DMA is directly related to time travel, as I had previously suggested. But if time travel is about to come into play, we could learn more about the ban and the Federation’s relationship to it.
Theory #21: We haven’t seen the last of the Abronians.
I currently have four ideas for different ways that the Abronians – the non-humanoid race that Captain Burnham, Tilly, and the Qowat Milat helped save from cryo-sleep in the episode Choose To Live – could play a further role in Season 4.
Theory #21-A: The Abronians’ homeworld was destroyed by the DMA.
Captain Burnham believes this image depicts a “supernova.”
After arriving at the Abronians’ cryo-ship, Captain Burnham found a stone carving that seemed to depict the destruction of the Abronians’ homeworld. This carving was only shown on screen briefly, but it seemed to show the planet being damaged or destroyed in a large explosion. Burnham credited the planet’s destruction to a “supernova,” and the story then raced ahead.
Considering that the main thrust of the season so far has been about the DMA, perhaps Burnham was incorrect: the Abronian homeworld was destroyed by the anomaly, not a supernova.
Theory #21-B: The Abronians’ homeworld was on the other side of the DMA.
Abronian stasis pods.
Now that we know a little more about how the DMA works, this theory seems a little more plausible. Its powerful wormhole technology seems capable of transporting matter over many light-years, meaning it doesn’t seem to be a complete stretch to think that the Abronians may have originated in the vicinity of Unknown Species 10-C. They could even be Unknown Species 10-C!
One thing struck me as odd about the Abronians: the Federation was entirely unaware of them, despite the Abronian cryo-ship being relatively close to Federation space – such that Captain Burnham could reach it using Book’s ship in a short span of time. It’s possible that the Abronians had been asleep for millennia, unnoticed by the Federation and the wider galaxy for all that time. But it’s also at least possible that their cryo-ship is a newcomer to the area. If so, perhaps it arrived here via the DMA.
With Captain Burnham and the crew about to visit the hyperfield, we could be about to find out if the Abronians originated in this region of space.
Theory #21-C: The Abronians will return to help the Federation later in the season.
A deceased Abronian.
One of the themes of Discovery since Season 3 has been connection, including building connections between the Federation and other races and organisations. The Abronians were awoken from cryo-sleep thanks to the interventions of Captain Burnham and Tilly – at least in part – and they may seek to repay the Federation, or Captain Burnham personally, for that help.
We saw this play out last season with Ni’Var; in the season finale Ni’Var ships raced to the Federation’s aid as the Emerald Chain attacked. Perhaps the Abronians will likewise step up to help when the Federation needs allies.
Theory #21-D: The Abronians’ moon-ship may be useful in a later story.
“That’s no moon…”
The cryo-ship used by the Abronians was huge, and appeared to have the mass of a planetoid or small moon. With Earth and Ni’Var now under threat and an evacuation necessary, perhaps the Federation will ask the Abronians to borrow their moon-ship. This could even be what Dr Kovich was planning to do and why he couldn’t join Discovery on the mission through the Galactic Barrier.
The moon-ship was fully operational thanks to the new dilithium that J’Vini “procured,” so it could be commandeered by Starfleet for the purposes of an evacuation. That would be one way to pay off what is, at the moment, a side-story.
Theory #22: Oros built the DMA.
The DMA on Discovery’s viewscreen.
There are similarities in the power generating technology used by the DMA and by Oros’ interdimensional transporter. At the very least, Oros seems capable of creating a power source on that scale, and thus he could be involved with Unknown Species 10-C… for some reason. The question of motive comes up – it doesn’t seem like a good way to attract attention, for example. But it’s possible that an explanation could be found!
Unknown Species 10-C could be native to Kayalise – the universe that Oros hoped to travel to. If so, Oros travelling there could have led to them learning about the prime universe – and that it’s a rich source of yummy boronite! They could have captured Oros, forcing him to build the DMA for them. Or he could have built it voluntarily.
So those theories are new or saw movement this week.
As always, I like to keep the entire theory list in one place, so I’ll recap the remaining theories that I have in play now.
Theory #23: Unknown Species 10-C built the Galactic Barrier.
The USS Discovery approaching the galactic barrier.
Given their technological capabilities, it doesn’t seem impossible that Unknown Species 10-C constructed the Galactic Barrier – perhaps as a way to shield themselves from the races of the Milky Way, or perhaps to keep anyone from exploring too far and discovering their location. There are many reasons why a technologically advanced race might want to build something on this scale – and we could even learn that the harvested boronite is being used to fuel the Galactic Barrier itself.
One possible explanation for why Unknown Species 10-C might want to build something like the Galactic Barrier is to keep the Milky Way’s inhabitants in… but it could also be a shield designed to keep someone else out. That raises a very frightening question: what could be so powerful that a barrier is needed around the entire galaxy? And what could be so dangerous that being locked inside a galaxy with the Borg would be preferable?
With Unknown Species 10-C seemingly being very secretive, I think the idea of them building it to shield themselves is more likely… but there are definitely a lot of ways this theory could go!
Theory #24: Someone else built the Galactic Barrier to keep Unknown Species 10-C out.
The Galactic Barrier.
If the Galactic Barrier is an artificial construct, perhaps it was created by another race or faction as a shield against Unknown Species 10-C. It could be the case that Unknown Species 10-C has used DMA technology against the Milky Way in the distant past, and some other race or faction constructed the Galactic Barrier to keep them out. If Unknown Species 10-C are belligerent and interested in conquest, it might take something on a galactic scale to keep the Milky Way safe. A race like the Q could be responsible if that’s the case.
Obviously this theory and the one above can’t both be right! And it’s a distinct possibility that the Galactic Barrier element of the story is just a convenient macguffin to blind Starfleet to Unknown Species 10-C and prevent easy travel to their region of space, dragging out the story and prolonging attempts at communication so other narrative threads could play out.
If that’s the case, we may learn nothing about the Galactic Barrier in the episodes that lie ahead! However, I still think it’s interesting to consider the possibilities, and it could be fun to finally get some more detail on this lesser-known but significant aspect of the Star Trek galaxy.
Theory #25: Unknown Species 10-C is a faction from a past iteration of Star Trek.
A Sphere-Builder from Enterprise.
Recent comments from Discovery’s showrunner during a social media event may indicate that this theory isn’t going to pan out, despite the mysterious elements and references to past Star Trek shows scattered throughout the season. In short, Michelle Paradise spoke about “designing” Unknown Species 10-C and how they’re “unlike any species we’ve seen before.” It’s still possible that we’re dealing with a faction like Picard Season 1’s super-synths, who were only seen on screen very briefly, or an extensive redesign of a race like the Borg to reflect centuries’ worth of technological progress.
I said last time that I was beginning to get a sense of déjà vu. Many of the suspects for Unknown Species 10-C also felt like plausible culprits for the Burn in Season 3 – and the way that storyline ultimately wrapped up was unpredictable (to say the least).
All that being said, there are still some plausible suspects, even if the DMA’s level of technology would seem to rule out many familiar races. The Borg, Enterprise’s Sphere-Builders, the extragalactic Kelvan Empire, V’Ger, Species 8472, the Q Continuum, and the Terran Empire are all high on my list! For a more detailed look at them, as well as a few less-likely contenders, check out my full list by clicking or tapping here.
Theory #26: Book and Burnham will reconcile and get back together.
Book and Burnham in Rubicon.
We saw a big step toward reconciliation – at least on Book’s part – in Rubicon, when he agreed to stand down and give Burnham and Starfleet a week to attempt to make peaceful first contact and convince Unknown Species 10-C to deactivate the DMA. Book was willing to take a risk by trusting that Burnham would permit him and Tarka to go ahead with their plan at a later time, and even though it didn’t pan out, the way he offered her his trust could open the doorway to reconciliation later on.
I haven’t enjoyed this aspect of the season’s storyline, so this is definitely a hope as much as a theory! But there is a way for Book and Burnham to reach a middle ground, and to find a way to set aside their differences and get back together. As mentioned above, doing so could lead to big changes for both of them – and even for Discovery itself.
Theory #27: Tarka will create his own DMA.
Tarka, Stamets, and Saru with the DMA model.
In The Examples, we saw Tarka – aided by Stamets – building a scale model of the DMA. Now that his plan to destroy it and seize its controller has failed, perhaps he’ll attempt to recreate the device using the knowledge he acquired. If so, he could inadvertently create a new DMA. Or, through time travel shenanigans, Tarka could turn out to be the creator of the original DMA!
If Tarka isn’t able to find a power source for his interdimensional transporter on the far side of the Galactic Barrier, he may feel he has no choice but to try and recreate the DMA’s original power source.
Theory #28: The Red Angel suits from Season 2 are connected to the DMA.
A Red Angel suit in Season 2.
Unknown Species 10-C seem to be responsible for building the DMA… whoever they ultimately turn out to be! But the DMA isn’t the first wormhole-creating technology that Discovery has introduced us to. The Red Angel suits in Season 2 were also capable of creating powerful wormholes… so could it be possible that Unknown Species 10-C built their device around or based on the same technology?
This revelation would greatly affect Captain Burnham, as she’d feel a degree of responsibility even though she wasn’t directly involved. It would also be the second disaster in a row (following the Burn) in which the Federation was implicated – albeit in an oblique way. I’m not convinced that Discovery will go down this route… but the similarities in the wormhole-creating technology gives me pause, at least.
Theory #29: Saru will be given the captaincy of the USS Voyager-J.
Captain Saru in command… of a shuttle!
Saru’s future was briefly discussed before he offered to serve as Captain Burnham’s first officer in the episode Anomaly. He has already been offered a command of his own, so Starfleet clearly values his command abilities and experience. President Rillak was seen to be assessing Captain Burnham’s suitability for the captaincy of the USS Voyager-J in Kobayashi Maru… and she mentioned having a shortlist of candidates. Could Saru be on her list?
Several of the qualities that President Rillak said she was looking for in a potential captain seem to apply to Saru. He’s more level-headed, less likely to put himself in a dangerous situation, and more inclined to think of the big picture. He has a weakness when it comes to Kaminar, as we saw toward the end of Season 3, but generally speaking he isn’t someone who lets his emotions get the better of him. His wisdom and calm demeanour could be valuable in the captain’s chair of the Federation flagship. This could also set the stage for his departure from the show, or possibly even for a new show following his adventures aboard his new ship.
Theory #30: The crew will have to defend the Verubin Nebula.
The dilithium planet is vital to the Federation.
This one is definitely hanging by a thread right now, at least in terms of Season 4! The story continues to unfold in a very different direction, largely ignoring the main story beats from Season 3. But the dilithium shortage has been mentioned more than once, and as things stand right now, the Federation is in control of the galaxy’s only significant dilithium supply. The Verubin Nebula is almost certainly going to be a target for somebody – even if Unknown Species 10-C don’t care about it.
It begins to stretch credulity to think that all of the belligerent factions and races present in the galaxy would become aware of the Federation controlling this impossibly valuable resource and wouldn’t want to take it for themselves. And while it may not happen now until after the DMA storyline has run its course, I think sooner or later someone is going to want to steal the Verubin Nebula and its dilithium. Maybe it will be at the end of Season 4, maybe it will be in Season 5… who knows?
Theory #31: Season 4 will connect with the Short Treks episode Calypso.
Zora dancing with Craft in Calypso.
Zora’s status as a member of the crew was confirmed in But To Connect, and this followed her developing emotions and sentience earlier in the season. Zora is now much closer to her presentation in Calypso, potentially bringing the story of the Short Treks episode one step closer.
There are still significant hurdles to overcome if the story of Calypso is to be wrapped up in Season 4, though. Obviously we have the timeframe issue: will the USS Discovery be sent back in time, be abandoned, or is Calypso taking place centuries in the future? Then we have the USS Discovery itself – it’s been retrofitted since arriving in the 32nd Century, and now looks very different to how it did in Calypso. I’m not sure how Discovery will overcome these hurdles – but it’s possible.
Zora hasn’t had a significant role to play in the last few episodes, but earlier in the season we definitely saw movement in this direction.
Theory #32: There will be a character crossover from a past iteration of Star Trek.
Star Trek has had some wonderful crossovers in the past.
There are many ways to bring back a character from a past iteration of the franchise and incorporate them into the story of Season 4 – and there would be many potential benefits to doing so! I had initially proposed a version of this theory in the run-up to Season 3 that centred on the Doctor from Voyager – but with some creative technobabble, practically anyone could be included, despite the leap forward in time.
Choose To Live showed us the Abronians in cryo-sleep, and Stormy Weather saw the crew of Discovery use the transporter buffer to survive – just like Scotty had done in The Next Generation Season 6 episode Relics. Could these be hints at something to come?
It would also be possible for Captain Burnham to discover the logs or a holographic recording of a long-dead character – and while this would be less of a “crossover,” it could still be a ton of fun and great fan-service!
Theory #33: Some areas of the galaxy – such as the Delta Quadrant – avoided the worst effects of the Burn.
Adira and Stamets with a map of the Milky Way galaxy.
In But To Connect, President Rillak told us that the diplomatic summit she convened would bring together races from “all four” quadrants. Assuming she was referring to the familiar Alpha, Beta, Gamma, and Delta Quadrants that make up the Milky Way galaxy, this would count as our first mention of the Delta Quadrant in the 32nd Century. I didn’t spot any familiar Delta Quadrant races (or their emblems) amongst the assembled delegates, however!
I had previously speculated that the Burn may not have affected the entire galaxy equally, and that regions farthest away from the Verubin Nebula may have survived without much damage. I still think that this is a possibility – though whether Discovery will revisit the Burn in any depth, or visit the Delta Quadrant at all, remains unclear.
Theory #34: Book will find Kyheem and Leto on the other side of the DMA.
Book and Kyheem in Season 3.
In Star Trek: Generations, Captain Picard encountered Captain Kirk inside the Nexus – despite Kirk being declared “dead” after the Enterprise-B encountered the energy ribbon almost eighty years earlier. Now that we know a little more about how the DMA operates, it seems at least faintly possible that, just like Captain Kirk, the inhabitants of Kwejian may not be as dead as they first appear.
This theory is, I freely admit, a bit of a long-shot. But the wormhole technology that we know the DMA uses seems to be capable of sending some of what it harvests or mines back to Unknown Species 10-C’s base of operations. Maybe that means that some of the people from Kwejian were transported there instead of being killed. With Discovery now en route to the hyperfield, perhaps a reunion with Kyheem and Leto is possible!
So that’s the main theory list!
We now have three production-side theories in play, so we’ll look at those too before we wrap things up.
Production-side theory #1: There will be some kind of crossover with Star Trek: Picard Season 2.
La Sirena in Picard Season 1.
This theory has arisen in large part because of the very odd scheduling for the next three weeks! Picard Season 2 and Discovery Season 4 will run alongside each other for three episodes, and I wonder if that’s because some kind of crossover is on the agenda. With time travel playing a significant role in the story of Picard Season 2, it seems at least plausible to think that some kind of connection is possible!
This could be a complete over-reach, and the ultimate “explanation” for the weird scheduling may turn out to be nothing more than the random illogical spasms of the ineptly-managed Paramount+ and parent company Paramount Global. That would not surprise me in the slightest! But I really do find the scheduling odd.
Admiral Picard as seen in one of the recent trailers for Season 2.
The shorter seasons of today’s Star Trek shows means that there really isn’t any need for such a pile-up this spring. Discovery has thirteen episodes, Picard and Strange New Worlds have ten apiece – and even with Lower Decks and Prodigy still to come, there are more than enough weeks in 2022 for the entire Star Trek franchise to be evenly spread out. Why have four out of the next ten weeks with two episodes from two different shows, then a gap of several weeks later in the year where no new Star Trek is broadcast? It makes no sense – especially not on a streaming platform.
Finally, with the constipated international rollout of Paramount+ showing no signs of speeding up, it’s looking increasingly likely that Strange New Worlds will be broadcast in the United States weeks or months ahead of its international premiere. If both Picard Season 2 and Strange New Worlds were delayed by as little as 4-5 weeks, this might be able to be avoided – assuming the rollout of Paramount+ “by the end of Q2” happens as planned.
In short, it’s all very strange – but one possible explanation for the weird scheduling could be that there’s a crossover event planned sometime in the next three weeks!
Production-side theory #2: Tilly’s departure will be permanent.
Tilly’s departure feels permanent.
Mary Wiseman confirmed in an interview with Wil Wheaton on The Ready Room (Discovery’s social media aftershow) that Tilly will be seen again before the end of Season 4, and we glimpsed her in the trailer for the second half of the season as well. But that doesn’t mean she will return as a main character on the show going forward, and her departure in All Is Possible felt permanent. Despite that, I’ve seen quite a lot of folks online who don’t believe that Tilly is actually leaving the series – so I wanted to put it out there officially and say that, in my opinion anyway, she is.
Maybe those people know something that I don’t! As I always say, I don’t have any “insider information;” all of this is just speculation on my part. However, I feel that the manner of Tilly’s departure, the fact that she got that emotional sequence with Captain Burnham, a montage showing her leaving the ship, Adira seeming to take over several of her roles, and her departure feeling like the culmination of her arc going back to the latter part of Season 3 all come together to strongly indicate that she won’t be back as a major character. She may yet have a significant role to play in a future Season 4 episode, as has been suggested, but unless Discovery’s writers are really playing with our emotions I believe we’ve seen Tilly’s end as a main character on the show. She may come back in a future Starfleet Academy series, though… so watch this space!
Production-side theory #3: Season 4 will end on a cliffhanger!
Star Trek has a long, well-established tradition of season-ending cliffhangers! There have been some truly shocking ones in the past, including The Best of Both Worlds in The Next Generation, Deep Space Nine’s Call To Arms, Equinox in Voyager… and many more! With the story of Unknown Species 10-C and the DMA slowly being unpicked, it could be the case that we’ll get a clean resolution – like we did at the end of Season 3. But it’s also possible, in my opinion, that Season 4 will end in similar fashion to Season 2 – on a major cliffhanger!
That could be because the Unknown Species 10-C story didn’t conclude, or a war with the mysterious faction is about to break out. But the Season 4 finale could also set up the beginnings of Season 5’s story, just like how the final moments of Season 1 saw Captain Pike’s Enterprise link up with the USS Discovery.
So that’s it!
The USS Discovery at warp.
Phew, this list is getting longer and longer… and harder and harder to write up in time every week! I surely hope that the upcoming episode – Rosetta – will start whittling down the theory list somewhat! Joking aside, I have a lot of fun putting these lists together, and I’ve even kicked off my Picard Season 2 theories as well. You can check out those by clicking or tapping here.
There’s still a lot on the table as we approach the final three episodes of the season – and so many different directions that the story could take. I honestly don’t know what’s going to happen… and I love it!
Before we go, one final point. I write up these theories because I like Star Trek and I like writing. But for some folks, fan theories can hamper their enjoyment of a film or television show. It’s worth keeping in mind that most of these theories probably won’t pan out, and we have to be prepared for the fact that even the most well-constructed fan theory, no matter how fun and plausible it seems, simply won’t turn out to be true. If you find that speculating and reading theories is beginning to detract from your enjoyment of Star Trek: Discovery – or any other television show or film – it might be a good idea to take a break for a while.

Spoiler Warning: There are spoilers ahead for Star Trek: Discovery Seasons 1-4. There are also minor spoilers for Star Trek: Picard Season 1 and the most recent trailer for Season 2.
Don’t get confused! According to Star Trek, there are not one but two barriers in the galaxy: one around the centre called the “Great Barrier” and one around the edge called the “Galactic Barrier.” They are not the same thing, and Discovery took us to the outer edge this week, not the centre! Two barriers, one galaxy. I hope that clears it up for you!
After being underwhelmed by the last couple of episodes, mostly due to their heavy focus on Captain Burnham’s angst over the situation with Book, The Galactic Barrier came along like a breath of fresh air. Though it relies heavily on the DMA and Unknown Species 10-C storylines, it came across on screen as two almost standalone sci-fi adventures, one starring Captain Burnham, President Rillak, and the crew of the USS Discovery, and the other focusing on Book and Tarka as they tracked down a rare element that they needed to cross the galactic barrier.

Both of these stories worked incredibly well for me, and showcased how strong Discovery can be when it doesn’t overdo the character drama. This isn’t a soap opera – and when the show’s writers get the right balance between fun sci-fi antics and intimate character moments, we’re treated to what I genuinely believe is some of the best science fiction ever brought to screen – and some of the best Star Trek, too.
The central character pairings of Book and Tarka on one side and President Rillak and Captain Burnham on the other worked brilliantly this week, and when the adventures paused to spend time on these character relationships, it was a welcome break from the incredibly drawn-out conflict between Book and Burnham that had dominated the past two episodes to the detriment, I would argue, of other aspects of the season’s storyline.
Captain Burnham got a much-needed break from Book this week.
I wrote last week that the DMA/Unknown Species 10-C story was unfolding in a very similar way to the Burn last season – and, to an extent, Control and the Red Angel in Season 2 as well. Discovery is definitely still flirting with repetitiveness in that regard, but with The Galactic Barrier telling these two semi-standalone stories of the mission to cross the Galactic Barrier and Book and Tarka’s antimatter harvest, at the very least we got a bit of a break from that feeling of déjà vu that had been present.
Let’s get what is perhaps the least impressive part of the story out of the way first: Earth being in danger is such a played-out cliché in stories like these. It was hard to avoid rolling my eyes when Admiral Vance’s holographic message dropped that particular bombshell, and I find myself repeating something I’ve said about Discovery on several occasions in Season 4, Season 3, and all the way back to the beginning: the show is strong enough and its storylines are interesting enough in their own right that there’s no need for this. Falling back on tired tropes doesn’t really do anything to ramp up the tension; the mission to contact Unknown Species 10-C is already sufficiently tense, exciting, and dangerous that there’s nowhere left to go.
Admiral Vance’s holo-message.
For me, this wasn’t so much an epic fail as a piece of unnecessary fluff. I wish Discovery’s producers and writers had more confidence, sometimes, in the stories they want to tell. When a fictional setting is built up as well as Star Trek’s, and when we already know the stakes involved thanks to what happened to Kwejian, there’s no need to put Earth in harm’s way – doing so almost detracts from the story, because now we know for absolute certain that Captain Burnham will find a way to save the day! If another planet was in danger – say, for example, the Breen homeworld or Bajor – the story could still go in any direction. We saw with the destruction of Kwejian that the writers are happy to blow up planets. But when it’s Earth, far from feeling like the planet is in serious danger and Captain Burnham might not be able to save it in time… now I’m left with a sense that the story’s conclusion is an inevitability rather than a possibility.
But aside from that unsuccessful attempt at taking the stakes from a ten to an eleven, The Galactic Barrier was impressive all-around. The visual effects of the titular barrier were impressive, and it was a rare treat to see the USS Discovery at warp! I love the spore drive, don’t get me wrong, but warp drive has been a huge part of Star Trek going back to the beginning, so to see the USS Discovery at warp for what I think is the first time this season and only the second or third time since the end of Season 2 was beautiful. The updated look of ships at warp is absolutely fabulous, and I never tire of seeing it.

The Galactic Barrier had originally appeared in The Original Series, first in the show’s second pilot, Where No Man Has Gone Before, and again in the third season episode Is There In Truth No Beauty. The latter episode featured a pocket of space within the barrier, something that Discovery also used to great effect this week, which was a fantastic callback to the very beginnings of Star Trek.
Discovery has been criticised in the past for treading on the toes of the established canon of Star Trek. Some of that criticism is fair, some arguably is very nitpicky, but we’re getting off the subject! In The Galactic Barrier, Discovery didn’t overwrite anything but instead expanded on our knowledge of how this unusual phenomenon works. Using the way the Galactic Barrier had been set up in The Original Series as a baseline, the episode took the concept and fleshed it out, explaining why travelling through it is so difficult and showing why it hasn’t been attempted in such a long time. As the Star Trek franchise continues to grow, I’d like to see more of this kind of thing. Picking up an element from the franchise’s past and looking at it in more detail without overwriting what came before is incredibly rewarding for long-time viewers, and I hope that other Trekkies who enjoyed The Original Series are as impressed as I am with Discovery’s approach this week.
The Galactic Barrier was visually impressive.
I was wrong in my theory that Ruon Tarka’s friend was someone we might be familiar with… and I have to say that I’m a little confused by the way this unfolded. I always caveat my theories by saying that they probably won’t pan out and that getting too attached to fan theories is a bad thing, and I also said from the beginning that I might well be overreaching by suggesting potential crossover characters for Tarka’s friend. But as we moved through three episodes with this individual’s identity being deliberately hidden by Discovery’s writers, I felt increasingly sure that there must be a reason.
The revelation that the character of Oros was someone brand-new is fine, and I actually like the relationship between he and Tarka that The Galactic Barrier showed us in flashback form. There was a sweetness to Tarka that we haven’t really seen before, and a hint – just a hint, at this stage – that the relationship goes beyond mere friendship. All of that is totally fine, and is even good; it adds dimension and complexity to Tarka and helps turn him from a villain into an antihero we can root for. But I have to question why this character’s identity was so carefully hidden until this episode. What was the point? Was it just to throw out a red herring, to send fans like me into theory-crafting overdrive? If so, that seems a little cruel. It just feels like naming Oros as far back as But To Connectwouldn’t have done any harm to the flashbacks in The Galactic Barrier, and that there wasn’t any reason to go to such lengths to keep Oros’ name and identity a secret for so long.
Ruon Tarka’s “friend,” Oros.
Since Tarka’s first appearance in The Examples earlier in the season he’s been much more than just a “mad scientist” character trope. His characterisation may have begun with that archetype, but the complex and nuanced character that we’ve come to know is so much more than that. We saw this week how he dealt with defeat: his weapon had failed to get him the power source he’s so desperately seeking, and through the flashbacks with Oros and his conversations with Book, we also saw how he’s a genuinely loving and caring person, willing to go to extremes to reach someone he cares about. In a series that has been all about finding and holding onto connection, Tarka fits the mould in a different way, but no less of an important or impactful one.
The relationship between Book and Tarka is evolving, too. Tarka had been in control for much of their time together, dictating how the weapon would be built, what components he needed, and so on. But this week we saw Book take back control – firstly by threatening to kick Tarka off his ship, and secondly by demanding to know the full story of what happened with Oros and what’s driving him.
Book and Tarka make a great character pair.
Book has been pretty static the past few episodes; his development this season came earlier as he grieved for Kwejian, leading up to his betrayal and team-up with Tarka before the mid-season break. And I don’t think we saw a lot in The Galactic Barrier to further develop or explore the extent of Book’s grief or how he’s dealing with his feelings of loss, but what we did get was someone trying to reassert himself and regain control of a situation that I’m sure even he would admit has spiralled out of control.
Despite his complex relationship with Tarka, finding out more about the man he’s stuck with seemed to be important to Book, and the revelation of Tarka’s past seems to have solidified their partnership, at least in the short-term. It would have been possible for Book to take the antimatter and ditch Tarka if he’d wanted to; he seems to recognise that, at least for now, it’s in his interests to continue to work together. I suspect that there will be some pay-off to this if and when the pair make it across the Galactic Barrier – and I’m still rooting for Tarka to find a way to reach Oros. In spite of his misdeeds (or perhaps because of them), I find him a strangely relatable character.

One thing that wasn’t addressed in The Galactic Barrier was the status of Book and Tarka. Are they fugitives now, having detonated their weapon? Is Book in less trouble than Tarka having indicated his willingness to stand down? It seems as though Book assumes he needs to remain off the grid, otherwise I would’ve expected him to have at least tried to reach out to Burnham; their parting of the ways in Rubicon seemed to suggest a middle ground between them was possible, and from there perhaps even a pathway to reconciliation. I’m sure Discovery will address this before the end of the season, but it was interesting that Book and Tarka’s status wasn’t really discussed here.
One thing that’s baffled me ever since it was announced a few weeks ago is the scheduling of the next few episodes of Discovery. They will overlap with the first three episodes of Picard Season 2… and on a streaming platform I just don’t get why that is. This is something that I’ll address in more detail in my next theory post, but I wonder if there’s a possible crossover on the cards and that’s why the weird scheduling has happened. If so, perhaps we got the very first hint at it in The Galactic Barrier, with a reference made about Vulcans observing Earth prior to official first contact taking place. This could be a reference to the events of the Enterprise episode Carbon Creek, but it could also be an oblique reference to something we’re about to see in Picard Season 2 – the most recent trailer showed off a Vulcan (or perhaps a Romulan) on what appeared to be 21st Century Earth. We’ll dig deeper into this possible crossover in my theory post in the days ahead, so stay tuned for that!

The burgeoning relationship between Saru and T’Rina took a turn this week, with Saru responding to T’Rina’s earlier invitation to dinner. There’s something adorable about the way both of these characters behave; they’re clearly not used to reaching out to someone else in this way, and the almost teenage awkwardness of asking someone out and worrying about saying the wrong thing is made so much cuter by the fact that they’re both usually so calm, wise, and stoic.
I’m glad that Discovery has given this kind of new relationship to Saru. It would’ve been easy, in a series with a lot of relationship drama coming from its protagonist, to either completely ignore the possible relationships between other characters or to give them easy, comfortable, safe relationships that don’t take up a lot of screen time. Discovery learned the hard way from messing with the Stamets-Culber relationship that these things don’t always come across well on screen, so taking a bit of a risk here with Saru and T’Rina is bold – and it’s working exceptionally well, injecting some lighter moments into a series that can be very heavy at points. It’s also sweet to see Dr Culber helping Saru as he takes these first steps into his very own new frontier; they work so well as a pair in these moments.
T’Rina and Saru.
So who do we think the Federation Vice President is? My money is on Kovich right now; I don’t see another plausible candidate among the very limited Federation HQ minor characters, and there was something about the way that President Rillak and Admiral Vance went out of their way to avoid using the VP’s name that makes me think that there could be a significant revelation to come. Kovich has remained ambiguous since we met him in Season 3, and although he went through some significant growth this season, particularly in episodes like All Is Possible, the events of The Galactic Barrier seem to have placed him right back in that mysterious space.
What is Kovich doing that’s more important than dealing with Unknown Species 10-C? And will this be paid off at all, or was it just a conveniently ambiguous line to move him out of the way so President Rillak could go on the mission? Sometimes it feels like Discovery has a plan with these moments, but then when the story ends and the dust settles, they turn out to be nothing more than throwaway lines! So right now I feel that there should be something bigger going on with Kovich – and again I’ll take a look at a couple of possibilities in my upcoming theory post – but at the same time, Discovery’s track record, and the fact that there are only three episodes left, makes me question whether we’ll see anything for ourselves.
Dr Kovich… Vice President of the Federation?
In a way, I enjoy Kovich’s ambiguity and the somewhat mysterious nature of his role within the hierarchy of the Federation. Speculating is always fun, but at the same time if Kovich’s position was fully explained and his role fleshed out, there’s a chance he might lose what has made him such an interesting part of the show over the past couple of seasons. I had initially pegged Kovich as a villain, perhaps a Section 31 leader or something like that. But episodes like But To Connect showed off that he at least appears to be committed to Federation principles, so I’m not sure about that any more, and I even struck the “Kovich is Section 31” theory off my list a few weeks ago.
We’ll save the guesswork for my theory post, but suffice to say I can think of a few reasons – both good and evil – for what role Kovich might play and why he might’ve chosen to recuse himself from the mission through the Galactic Barrier. I hope that, whatever’s happening with him, we don’t lose him as a character by the end of the season. With Discovery returning for a fifth season, I would hope Kovich could stick around for more ambiguous adventures!
Kovich and the rest of the senior officials.
Speaking of Kovich, it was said on several occasions this season that Lieutenant Commander Bryce is working closely with him, and he got a scene this week in which he parted ways with Saru that was very sweet. Although Bryce has been a secondary character, his goodbye with Saru hit all of the emotional notes that I might’ve expected from a major character, and this scene genuinely felt like two good friends parting ways, knowing that it could well be for the final time.
There weren’t that many characters with whom we could’ve gotten similar scenes, so in that sense it’s logical to use Bryce here – and actor Ronnie Rowe Jr. put in a beautiful performance opposite Doug Jones. The pair really sold me on this moment, and it was a surprisingly emotional scene given that Bryce has never been the focus of a major story across the show’s four-season run to date. Again, this is something to speculate about in-depth next time, but I wonder if Discovery plans to pay off Bryce’s story of working with Kovich in some way. Perhaps the two of them will work together to save the day… or perhaps Bryce won’t survive, and this moment with Saru was the equivalent of his goodbye to the series and to us as the audience!
Are we about to say goodbye to Bryce?
I stand by what I’ve said about President Rillak in her past appearances: she’s a hard-nosed politician with a Machiavellian edge, willing to use other people to manipulate events to get the outcome she’s looking for. But this week we saw – dare I say – an almost altruistic side to the Federation’s President, as she delegated power to her Vice President and accompanied the USS Discovery on its mission through the Galactic Barrier.
It’s still possible, in my view, that Rillak has an ulterior motive here. But at the same time, it was nice to see her recognising her mistake from the season premiere – in which her questioning and time-wasting on the bridge in the middle of a crisis was completely out-of-line… and arguably got poor Commander Nalas killed. Some characters on Discovery have arguably been less good at recognising their own mistakes and learning from them, so this was something nice to see; a moment of (apparent) contrition from a wonderfully complex character. As she has done all season long, Chelah Horsdal absolutely nailed it.
President Rillak joined the mission.
Captain Burnham showed last week that she has a weakness when it comes to Book – understandably so. But that weakness definitely had an impact on her ability to command her ship level-headedly, to such an extent that Nhan was given authority to overrule her if it came down to the wire. This week, with Book effectively out of the picture, we got to see a much more composed Captain Burnham, and she remained fully in control of the ship and crew as they made their way through the Galactic Barrier.
For me, this hammers home why the whole relationship drama angle that Discovery has aggressively pursued for the last few weeks is such a mistake. Captain Burnham is at her best when she’s composed and in control, able to draw on her inner strength to be the kind of leader that we know she can be. When she’s distracted unnecessarily by a fairly pedestrian and poorly-written soap opera-inspired boyfriend angst storyline, we don’t see her at her best. Female characters – especially leading characters like Captain Burnham – are done a disservice by the show’s writers and creatives if all they’re permitted to do is sit around and worry about the men in their life. By cutting the crap this week and focusing on what was a fun sci-fi adventure story in its own right, Discovery once again allowed Captain Burnham to shine.
Stepping away from Book was good for Captain Burnham this time.
Discovery presented Captain Burnham and President Rillak with a complicated question after Admiral Vance’s holo-message arrived. There isn’t an easy, clear-cut answer in situations like these, and I can understand both Captain Burnham’s position of wanting to share the news about the danger to Earth and Ni’Var with the crew so they know the full picture and understand the stakes, but also from a practical point of view, I can understand President Rillak’s wish to keep the information private, at least in the short-term.
President Rillak wanted to avoid losing control of the situation, which is understandable psychologically for someone in a position of authority. But more so I think her point about not wanting to leave the crew with an unnecessary distraction that could interfere with their work is a valid one; at the very least, waiting until the dangerous mission to navigate the Galactic Barrier was complete seems like a perfectly reasonable and sensible position to take.
President Rillak and Captain Burnham.
Because this is Discovery, though, and despite all the talk last week of “finding a middle ground,” Captain Burnham had to win this particular argument, and after a conversation with President Rillak, the news was ultimately shared with the crew and the assembled delegates. I like, however, that they waited until the most dangerous part of the mission had concluded before doing so – it feels like somewhat of a compromise under the circumstances.
It was interesting to learn that the mycelial network doesn’t extend beyond the edge of the galaxy. The network seemingly connects at least two parallel universes – the prime and Mirror – so it seems odd that it has this limitation. Obviously, though, for the sake of the story a way around the spore drive had to be found, but it does feel at least slightly inconsistent with previous statements about the mycelial network spanning an entire multitude of universes. This is really just a nitpick, though, in the grand scheme of things, and the mycelial network being a galactic phenomenon allowed Discovery to tell one of the most exciting and interesting stories of the season so far.
Dr Hirai.
I’m interested to learn more about Dr Hirai, the new character introduced in this episode, but he ultimately didn’t get a lot to do on this occasion. The talk of universal translators and making assumptions about Unknown Species 10-C was all very interesting, but until we actually get to see this faction for ourselves it was a bit of background that may or may not come into play… and it feels like it was there as an excuse to show off some combadges and other props more than anything else!
So I think that’s about all I have to say this week. The Galactic Barrier was one of the best episodes of Season 4 so far, telling two distinct stories that took our characters to some very different literal and thematic places. The sci-fi adventure of overcoming the odds to navigate a dangerous phenomenon was a ton of fun, and stepping away from the show’s recent focus on Captain Burnham and Book allowed both characters some much-needed breathing space. The show itself took advantage of this, too.
I had a ton of fun with The Galactic Barrier, and it’s an episode that I’ll happily rewatch for its semi-standalone adventure story when the season is over. With only three episodes remaining, surely we’re close to learning who Unknown Species 10-C are… right?

After All In failed to move the needle in a major way, Rubicon came along! The latest episode saw a minor theory cull, with three theories being debunked – and a couple of others moving ever closer to being struck off the list! As the season builds up to its conclusion, this was bound to start happening, and I don’t lament the passing of any of the theories that didn’t pan out. We also had a rare confirmation this week, and with fewer new theories to talk about, the list will shrink for the first time in several weeks!
On reflection, perhaps I was a little harsh on Rubicon in my review. The episode was decent, but it suffered because I find myself struggling to get invested in the Book-versus-Burnham relationship squabble storyline, and that’s been a dominant force over the past couple of episodes in particular. I’m still hopeful that Discovery will find a sensible – and fairly quick – resolution to this, but at the same time I think I need to try to be less petty about it!
So let’s take a look at the confirmation and the debunkings before we jump into the main list.
Confirmed theory: Tarka’s weapon will be successful.
Kaboom!
The obvious path for a “happily ever after” kind of story would have been for Captain Burnham and the crew to stop Book and Tarka before they had a chance to use their weapon. And, to her credit, Captain Burnham was inches away from success as she managed to talk to Book and convince him not to deploy the weapon.
But I guess that in her haste to patch things up with her boyfriend, Captain Burnham forgot about Tarka. And Book likewise didn’t make sure that Tarka was on board with his decision to wait for the communication attempt, as Tarka launched his weapon the second Book and Burnham finished their conversation.
Tarka launched his weapon.
I’m glad that the story took this route. It potentially opens up a more interesting meeting with Unknown Species 10-C, one with more tension and the possibility of conflict. But most importantly, Tarka remained true to his characterisation. He didn’t back down just because Book had a change of heart, and he wasn’t able to be persuaded by Captain Burnham’s request.
Tarka remains an interesting adversary. I don’t want to call him a “villain,” not exactly. He has a complexity and a nuance that makes his motivation understandable, even if his “ends justify the means” approach could very well lead to people getting hurt. I’m not ready for Discovery to get rid of Tarka… and I confess that I’m still rooting for him to find a way across the divide between universes.
So that theory was confirmed.
We also have several debunkings to get through, so we’ll run through those next!
Debunked theory #1: Nhan works for Section 31.
Nhan in Rubicon.
This was a fairly straightforward one by my standards! When we saw Nhan in the promos for Rubicon, I theorised that she might be wearing a different uniform to the standard Starfleet ones worn by Captain Burnham and the crew because she had been recruited by Section 31. She could have been given a Section 31 mission aboard Discovery – perhaps connected to the DMA.
But it didn’t come to pass! Nhan works for Starfleet Security, and has spent some time as a soldier helping the Federation battle against the remaining forces of the Emerald Chain. She doesn’t appear to be making a big return to Discovery, either, merely appearing in a guest role in Rubicon.
Debunked theory #2: Tarka will realise that there’s a tracker on the isolynium.
Tarka and Book working on the isolytic weapon.
This was another fairly simple one by my standards. In short, I speculated that Tarka would check the isolynium that Book procured and figure out that a tracking device had been placed on it. It seems like the kind of thing he might’ve done; he’s been thorough when it comes to his work, and he clearly didn’t fully trust Haz Mazaro.
But Tarka didn’t check, or if he did off-screen he didn’t find the small tracking device that Captain Burnham had placed. If this theory had panned out we could’ve seen Captain Burnham and the crew having to pick up the trail another way, or even being led into a booby-trap of Tarka’s devising! In a longer season, perhaps such a detour would have made sense. With only four episodes left, I guess wasting an episode chasing down Book and Tarka would’ve been extraneous fluff.
(Probably) debunked theory #3: The DMA is (or was) a life-form.
The DMA in Rubicon.
It was never stated outright in clear-cut terms, but this theory now feels sufficiently unlikely that I’m striking it from the list. If the DMA was alive… it isn’t anymore! Tarka’s weapon saw to that. The arrival of a second DMA within moments of the demise of the first seems to confirm that the destructive anomaly is little more than a tool; the dredge or mining equipment that Captain Burnham and others figured out at the end of All In.
Unknown Species 10-C could still be a synthetic race, so the concept of a life-form on the scale of the DMA is still plausible in Discovery Season 4. But the DMA itself now seems certain to be little more than a tool – whoever is controlling it is the sentient one. It might’ve been interesting if the DMA had been alive, with a story similar to The Motion Picture perhaps unfolding from that premise. But now we must look to Unknown Species 10-C!
So those theories have been debunked!
Now let’s jump into the main theory list, beginning with those theories that are either new or saw movement in Rubicon. Then we’ll conclude with a few theories that are still in play, but which Rubicon didn’t touch.
Theory #1: Unknown Species 10-C built the Galactic Barrier.
The USS Enterprise approaching the galactic barrier.
I’ve never been wild about the Galactic Barrier in Star Trek. It’s something that dates right back to the very beginning of The Original Series, but it’s always struck me as a bit of an oddity; an element of pure fantasy in a setting that prefers to base its astronomy on real science. The Galactic Barrier is also rather poorly explained, and can seemingly be ignored at the whim of Star Trek’s writers – some episodes depict crossing it as being impossible, others show starships moving through it with ease. It also feels like a 2D anachronism in the 3D realm; unless the galactic barrier is a sphere, surely flying up and over it should be possible!
But maybe we’re about to learn more about this strange phenomenon. Given their technological capabilities, it doesn’t seem impossible that Unknown Species 10-C constructed the Galactic Barrier – perhaps as a way to shield themselves from the races of the Milky Way, or perhaps to keep anyone from exploring too far and discovering their location. There are many reasons why a technologically advanced race might want to build something on this scale – and we could even learn that the harvested boronite is being used to fuel the Galactic Barrier itself.
The Enterprise-D is one of a number of vessels known to have passed through the Galactic Barrier.
One possible explanation for why Unknown Species 10-C might want to build something like the Galactic Barrier is to keep the Milky Way’s inhabitants in… but it could also be a shield designed to keep someone else out. That raises a very frightening question: what could be so powerful that a barrier is needed around the entire galaxy? And what could be so dangerous that being locked inside a galaxy with the Borg would be preferable?
With Unknown Species 10-C seemingly being very secretive, I think the idea of them building it to shield themselves is more likely… but there are definitely a lot of ways this theory could go!
Theory #2: Someone else built the Galactic Barrier to keep Unknown Species 10-C out.
The Galactic Barrier on the USS Enterprise’s viewscreen.
If the Galactic Barrier is an artificial construct, perhaps it was created by another race or faction as a shield against Unknown Species 10-C. It could be the case that Unknown Species 10-C has used DMA technology against the Milky Way in the distant past, and some other race or faction constructed the Galactic Barrier to keep them out. If Unknown Species 10-C are belligerent and interested in conquest, it might take something on a galactic scale to keep the Milky Way safe.
The Q Continuum spring to mind as a possible candidate if the Galactic Barrier was artificially created. Admiral Vance mentioned the Q a few episodes back, saying that there hadn’t been any contact for more than 600 years. Given that the Q – or at least one member of the Continuum, at least – were very interested in the progress of races like humanity, perhaps they took a decision to “seal” the Milky Way to protect its inhabitants from Unknown Species 10-C.
Traversing the Galactic Barrier could be very dangerous…
Obviously this theory and the one above can’t both be right! And it’s a distinct possibility that the Galactic Barrier element of the story is just a convenient macguffin to blind Starfleet to Unknown Species 10-C and prevent easy travel to their region of space, dragging out the story and prolonging attempts at communication so other narrative threads could play out.
If that’s the case, we may learn nothing about the Galactic Barrier in the episodes that lie ahead! However, I still think it’s interesting to consider the possibilities, and it could be fun to finally get some more detail on this lesser-known but significant aspect of the Star Trek galaxy.
Theory #3: Tarka’s mysterious “friend” is someone we’re already acquainted with.
At this point in the story, there’s no need to conceal the identity of Tarka’s friend – unless the revelation of this person’s identity is going to be a huge surprise. It’s possible that there is no Unknown Species 10-C, for example, and that Tarka’s friend is the one responsible – a theory we’ll look at in more detail in a moment! But it has to be considered a possibility that Tarka’s friend is someone we’ve already met, either in Discovery or in another iteration of Star Trek.
Rubicon hammered home Tarka’s desperation to reach his friend, and All In had given us a quote from Tarka about his grief at this person’s loss being unfathomable. Perhaps that was hyperbole on the part of someone very self-centred, but even so it feels like there’s more going on with this mysterious character. If there’s nothing special about them, and they’re just a brand-new character called something like Albert or Gladys, then why go to such trouble to keep their identity hidden during every conversation? It’s setting up a mystery – and for Discovery’s sake I sincerely hope it goes somewhere!
I put together a short list of possible candidates for being Tarka’s mysterious friend, and you can find it by clicking or tapping here.
Theory #4: Unknown Species 10-C is a faction from a past iteration of Star Trek.
Could Unknown Species 10-C be the Kelvan Empire?
Rubicon didn’t do much to advance this theory – though the DMA controller seemed to bear a very superficial resemblance to omega molecules and possibly Borg tech – but comments from Discovery’s showrunner during a social media event may indicate that this theory isn’t going to pan out, despite the mysterious elements and references to past Star Trek shows scattered throughout the season. In short, Michelle Paradise spoke about “designing” Unknown Species 10-C and how they’re “unlike any species we’ve seen before.”
It’s still possible that we’re dealing with a faction like Picard Season 1’s super-synths, who were only seen on screen very briefly, or an extensive redesign of a race like the Borg to reflect centuries’ worth of technological progress. But I felt it was worth bringing this up, as it’s certainly our biggest indication to date that Unknown Species 10-C may be someone brand-new to the franchise.
Showrunner Michelle Paradise recently dropped a hint about Unknown Species 10-C.
I said last time that I was beginning to get a sense of déjà vu. Many of the suspects for Unknown Species 10-C also felt like plausible culprits for the Burn in Season 3 – and the way that storyline ultimately wrapped up was unpredictable (to say the least). As Trekkies who are invested in this fictional setting, I think there’s always going to be a desire to speculate and theorise about how big events in new stories could be connected to the elements from elsewhere in the franchise… I just hope that the ultimate reveal of Unknown Species 10-C doesn’t prove too disappointing if it has nothing to do with Star Trek’s past.
All that being said, there are still some plausible suspects, even if the DMA’s level of technology would seem to rule out many familiar races. The Borg, Enterprise’s Sphere-Builders, the extragalactic Kelvan Empire, V’Ger, Species 8472, the Q Continuum, and the Terran Empire are all high on my list! For a more detailed look at them, as well as a few less-likely contenders, check out my full list by clicking or tapping here.
Theory #5: Book and Burnham will reconcile and get back together.
Book and Burnham are currently separated.
Although I may have been excessively critical of it at points in this week’s review, I maintain that the Book-versus-Burnham conflict isn’t one that the show needs. It’s built on very weak foundations, with both of them (and everyone else on the show) needing to be incredibly blinkered (or incredibly stupid) and not being able to recognise a very basic pathway to the “middle ground” that became the focus of Rubicon’s story.
We saw a big step toward reconciliation – at least on Book’s part – in Rubicon, when he agreed to stand down and give Burnham and Starfleet a week to attempt to make peaceful first contact and convince Unknown Species 10-C to deactivate the DMA. Book was willing to take a risk by trusting that Burnham would permit him and Tarka to go ahead with their plan at a later time… whether she would or not is unclear!
Book and Burnham in All In.
So that’s a positive step. With the detonation of Tarka’s weapon, the story could go in one of two ways from here: either Starfleet will let them off the hook, with the debate over the weapon rendered moot by the arrival of a second DMA, or Book and Tarka will have to go on the run to avoid the consequences of their actions.
I would suggest that Tarka is a valuable asset to Starfleet, and they may want to bring him back into the fold to help work on the DMA problem, the Galactic Barrier problem, and other things. Book is far less important in that regard, but as he’d indicated his willingness to stand down he may not be in as much trouble. There’s a pathway here to bring an end to this feud – and I hope Discovery takes it in the next week or two.
Theory #6: Michael Burnham won’t remain captain of the USS Discovery.
Captain Burnham in Rubicon.
One potential way to pay off the Book-versus-Burnham storyline would be for it to lead to a significant change for Discovery’s captain. We saw in Rubicon that Burnham was unwilling to give the order that could have hurt or killed Book – even though she had been ordered to do so by Starfleet. This fundamental conflict between her romantic relationship and her duty is not new, and could potentially lead to Burnham stepping back from her role as captain of the ship.
Maybe she will have the strength to do what she believes is right during the DMA crisis, but will resign afterwards, unable to contemplate doing the same thing again and wanting to return to her simpler life with Book. This wouldn’t be a bolt from the blue, as we saw her wrangling with these feelings in Season 3.
In Season 3, Burnham had to consider whether remaining in Starfleet was right for her.
One of the unique aspects of Discovery within Star Trek’s broader canon is that the ship has been commanded by four very different individuals across its four seasons. Captain Burnham is different from Saru, Saru was different from Pike, and Pike, in turn, was different from Lorca. It has to be considered at least a possibility that the series will continue this trend.
I’m not really in favour of this, but it’s certainly interesting to consider. Now that we know that Season 5 is definitely happening, one possibility is that Captain Burnham will somehow leave the ship at or around the end of Season 4, making way for a brand-new commanding officer to take over. Because she’s been the show’s protagonist since Season 1, it seems unlikely, and the overall arc of Discovery between Season 1 and Season 3 can be read as Burnham’s redemption and ascent to the captaincy. But the show’s revolving door of captains may continue, and her conflict with Book and the difficult emotional situation it put her in could be the trigger to make this happen.
Theory #7: Tarka will create his own DMA.
Tarka, Stamets, and Saru with the DMA model.
In The Examples, we saw Tarka – aided by Stamets – building a scale model of the DMA. Now that his plan to destroy it and seize its controller has failed, perhaps he’ll attempt to recreate the device using the knowledge he acquired. If so, he could inadvertently create a new DMA. Or, through time travel shenanigans, Tarka could turn out to be the creator of the original DMA!
Tarka’s story isn’t finished yet, and there’s still time for him to devise and enact a new plan over the course of the next few episodes. He had plans for using the DMA controller, so the next-best thing from his point of view might be to build his own version. He’s certainly clever enough – all he really needs is access to the resources to pull it off.
Theory #8: Tarka’s friend built the DMA.
The second DMA in Rubicon.
As mentioned above, I think it’s a possibility that Tarka’s friend is directly involved with the DMA. It would explain how Tarka seems to know so much about it, even being able to recreate it on a smaller scale, as well as how he knows that it would be possible to use its power source to punch through to an alternate universe.
After all of the buildup, it’s possible that Unknown Species 10-C could turn out to be a single person: Tarka’s friend. It’s also possible that Tarka’s friend is working with Unknown Species 10-C, perhaps trying to find a way to reach Tarka across the divide between universes. There are a lot of different ways that this could pan out!
So those theories are new or saw movement this week.
Now, as I do every week, I’ll recap all of the other theories currently in play. I find it helps to keep everything in one place – it makes it easier to keep track of every theory so we can strike them off the list as we go!
Theory #9: We haven’t seen the last of the Abronians.
I currently have four ideas for different ways that the Abronians – the non-humanoid race that Captain Burnham, Tilly, and the Qowat Milat helped save from cryo-sleep in the episode Choose To Live – could play a further role in Season 4.
Theory #9-A: The Abronians’ homeworld was destroyed by the DMA.
Captain Burnham believes this image depicts a “supernova.”
After arriving at the Abronians’ cryo-ship, Captain Burnham found a stone carving that seemed to depict the destruction of the Abronians’ homeworld. This carving was only shown on screen briefly, but it seemed to show the planet being damaged or destroyed in a large explosion. Burnham credited the planet’s destruction to a “supernova,” and the story then raced ahead.
Considering that the main thrust of the season so far has been about the DMA, perhaps Burnham was incorrect: the Abronian homeworld was destroyed by the anomaly, not a supernova.
Theory #9-B: The Abronians’ homeworld was on the other side of the DMA.
Abronian stasis pods.
Now that we know a little more about how the DMA works, this theory seems a little more plausible. Its powerful wormhole technology seems capable of transporting matter over many light-years, meaning it doesn’t seem to be a complete stretch to think that the Abronians may have originated in the vicinity of Unknown Species 10-C. They could even be Unknown Species 10-C!
One thing struck me as odd about the Abronians: the Federation was entirely unaware of them, despite the Abronian cryo-ship being relatively close to Federation space – such that Captain Burnham could reach it using Book’s ship in a short span of time. It’s possible that the Abronians had been asleep for millennia, unnoticed by the Federation and the wider galaxy for all that time. But it’s also at least possible that their cryo-ship is a newcomer to the area. If so, perhaps it arrived here via the DMA.
Theory #9-C: The Abronians will return to help the Federation later in the season.
A deceased Abronian.
One of the themes of Discovery since Season 3 has been connection, including building connections between the Federation and other races and organisations. The Abronians were awoken from cryo-sleep thanks to the interventions of Captain Burnham and Tilly – at least in part – and they may seek to repay the Federation, or Captain Burnham personally, for that help.
We saw this play out last season with Ni’Var; in the season finale Ni’Var ships raced to the Federation’s aid as the Emerald Chain attacked. Perhaps the Abronians will likewise step up to help when the Federation needs allies.
Theory #9-D: The Abronians’ moon-ship may be useful in a later story.
“That’s no moon…”
The Abronians’ cryo-ship is huge, and at least superficially seems to have the mass of a moon or small planetoid. If Captain Burnham and the crew needed a starship that large, such as to aid in the evacuation of a planet threatened by the DMA, for example, perhaps they’ll return to the Abronians and ask to borrow it.
As we saw in Choose To Live, the moon-ship was in full working order. All it needed was some extra dilithium to power up and it was perfectly capable of moving under its own power, and its computer systems were still functional. The only system that seemed to have failed was the wake-up timer! Discovery has precedent when it comes to telling seemingly one-off stories that have a pay-off later on, so watch this space. If Captain Burnham and the crew need a huge starship urgently, we may not have seen the last of the moon-ship!
Theory #10: The Red Angel suits from Season 2 are connected to the DMA.
A Red Angel suit in Season 2.
Unknown Species 10-C seem to be responsible for building the DMA… whoever they ultimately turn out to be! But the DMA isn’t the first wormhole-creating technology that Discovery has introduced us to. The Red Angel suits in Season 2 were also capable of creating powerful wormholes… so could it be possible that Unknown Species 10-C built their device around or based on the same technology?
This revelation would greatly affect Captain Burnham, as she’d feel a degree of responsibility even though she wasn’t directly involved. It would also be the second disaster in a row (following the Burn) in which the Federation was implicated – albeit in an oblique way. I’m not convinced that Discovery will go down this route… but the similarities in the wormhole-creating technology gives me pause, at least.
Theory #11: Saru will be given the captaincy of the USS Voyager-J.
Captain Saru in command… of a shuttle!
Saru’s future was briefly discussed before he offered to serve as Captain Burnham’s first officer in the episode Anomaly. He has already been offered a command of his own, so Starfleet clearly values his command abilities and experience. President Rillak was seen to be assessing Captain Burnham’s suitability for the captaincy of the USS Voyager-J in Kobayashi Maru… and she mentioned having a shortlist of candidates. Could Saru be on her list?
Several of the qualities that President Rillak said she was looking for in a potential captain seem to apply to Saru. He’s more level-headed, less likely to put himself in a dangerous situation, and more inclined to think of the big picture. He has a weakness when it comes to Kaminar, as we saw toward the end of Season 3, but generally speaking he isn’t someone who lets his emotions get the better of him. His wisdom and calm demeanour could be valuable in the captain’s chair of the Federation flagship. This could also set the stage for his departure from the show, or possibly even for a new show following his adventures aboard his new ship.
Theory #12: The ban on time travel will be explained in more detail.
HMS Bounty was able to travel back in time in Star Trek IV: The Voyage Home.
This one is as much a hope as a theory right now! In short, the ban on time travel was introduced early in Season 3 primarily as a way for the writers and producers to avoid questions about why the 32nd Century was so different from how the far future had been depicted in earlier Star Trek productions, as well as to explain things like how the Burn was able to catch the Federation off-guard and why Georgiou couldn’t simply be sent back in time when she needed to.
But the ban itself raises some issues – the biggest one being the lack of detail on how it works and how something like this could possibly be enforced. As I said several times last season, it isn’t possible to just un-invent a technology so useful and powerful as time travel. Even just a few lines of dialogue going into a little more detail on the mechanisms involved in the ban would be really useful.
Theory #13: The Federation has flouted the ban on time travel.
President Rillak may have tried to circumvent the ban if she felt doing so would be in the Federation’s interests.
Sticking with the time travel ban, another theory I had last season was that the Federation – and Section 31 in particular – might have deliberately flouted the ban and failed to abide by the rules. Someone as straight-laced and committed to Starfleet ideals as Admiral Vance is highly unlikely to have sanctioned such a move, but there are other Federation leaders – such as President Rillak – who could be implicated.
I don’t think it’s possible any more that the DMA story will be connected to the time travel ban, as I had previously proposed. But that doesn’t mean that a closer look at the ban, and the potential for the Federation to have tried to work around it, isn’t going to happen.
Theory #14: The crew will have to defend the Verubin Nebula.
