Star Trek: Discovery theories – Season 4 finale

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, VoyagerEnterprise, 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!

Check out a full write-up of this theory by clicking or tapping here.

So those theories may return!

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 Worlds now 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. The Star Trek franchise – including Discovery and all other properties mentioned above – is the copyright of Paramount Global.

Star Trek: Discovery theories – week 12

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.

To see a full write-up of this theory, click or tap here.

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 GenerationDeep Space Nine’Call To ArmsEquinox 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.

Star Trek: Discovery theories – week 11

Spoiler Warning: There are spoilers ahead for Star Trek: Discovery Seasons 1-4, Star Trek: Picard Seasons 1-2, and for other iterations of the Star Trek franchise.

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.

Dr Kovich in the episode The Galactic Barrier.

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 GenerationDeep Space Nine’Call To ArmsEquinox 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!

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. The Star Trek franchise – including Discovery and all other properties mentioned above – is the copyright of Paramount Global.

Star Trek: Discovery theories – week 0

Spoiler Warning: There are spoilers ahead for Star Trek: Discovery Seasons 1-3 and the trailers and teasers for Season 4. Spoilers are also present for other iterations of the Star Trek franchise, including Picard Season 1.

Discovery’s fourth season kicks off next week, and if you missed my coverage of the series last year you might not know that I like to write up my theories after each episode has aired. This year I want to get in early and put all of my major pre-season theories into one place… that way we can cross them off as they get debunked – or possibly even confirmed!

Last year I had a lot of fun combing over each episode and trying to speculate and theorise where the story might go. I came up with many theories that were wide of the mark – check out some of my worst ones by clicking or tapping here! – but I did also get some things right.

A Ferengi Starfleet officer glimpsed in the second Season 4 trailer.

It’s important to caveat any list of theories by saying that I have no “insider information” and I’m not trying to claim that anything listed below will happen. Fan theories are a lot of fun for me, but they can also detract from a person’s enjoyment of media if they get too attached to a particular theory that ultimately doesn’t come to pass. If you find yourself in that position, I recommend taking a break from fan theories for a while.

So let’s have a bit of fun and kick off my Star Trek: Discovery Season 4 theories one week early! You might’ve seen some of these already – I’ve written up a few big pre-season theories over the past few months. Let’s jump into the list!

Theory #1: A major character will be killed.

A Starfleet coffin draped with the Federation flag as seen in Deep Space Nine.

Season 3 saw a couple of major departures: Mirror Georgiou entered the Guardian of Forever’s portal, and Nhan remained behind aboard the USS Tikhov. Yet despite the dangers the crew faced as they navigated the 32nd Century, battled the Emerald Chain, and figured out the mysteries of the Burn and the Verubin Nebula, only one ally – Ryn – lost their life.

Killing off a character can be an excellent way to communicate the stakes involved if it happens at a relatively early stage, and we know Captain Burnham and the crew will be facing a dangerous gravitational anomaly. It can also be a storyline that brings a lot of emotion, as we have to say goodbye to a beloved member of the crew.

Dr McCoy and Sulu playing dead in The Wrath of Khan.

In short, I think there are plenty of reasons on the production side why killing off a major character could make sense in Season 4. Discovery has seen a number of characters leave the series – far more than any past Star Trek show, in fact – but the series’ death toll is still relatively low when compared to many other modern television shows.

There are also a couple of characters whose roles aboard the ship feel in danger – not least of whom is poor ex-Captain Saru, who was rather unceremoniously shuffled out of his role in the Season 3 epilogue. For a full breakdown of which other characters may or may not be in danger, check out my list of “death predictions” by clicking or tapping here.

Theory #2: There will be a character crossover from a past iteration of Star Trek.

Voyager’s Doctor is a contender!

Yes, I’m officially bringing this theory back! This is one that I doggedly clung on to for all of Season 3, and while it arguably kind of happened with the Guardian of Forever, that wasn’t really what I meant.

The show’s 32nd Century setting has shot Captain Burnham and the crew far beyond anything in Star Trek’s established canon, and that should mean that practically everyone we remember from other Star Trek shows won’t be around any longer. But this is Star Trek – with some creatively-written technobabble, practically any major character could have survived all the way through to the 32nd Century!

Could Sutra still be alive in the 32nd Century?

It’s also possible for Captain Burnham to discover the logs of a long-dead officer; someone we as the audience would be familiar with. While this would be less of a “crossover” than if a character from the past could be physically present, it would still be a lot of fun to see!

There are a handful of characters who could have survived to the 32nd Century based on what we know about them from past iterations of the franchise. Included in this category would be people like Soji, Voyager’s Doctor, and a few others. But as we’ve seen in episodes like Relics and even the film Generations, all it would take to make a big crossover happen is some kind of temporal anomaly, stasis field, or other technobabble!

Theory #3: Burnham may not remain in the captain’s chair.

Michael Burnham in the captain’s chair in a promotional image for Season 4.

This is a controversial one, so let me just say up front that I’m neither in favour of this theory nor opposed to it – I just think it’s a possibility. As things stand, Discovery has had four different captains across its four seasons. One of the show’s unique points of interest within Star Trek’s broader canon are the differences between these very different individual captains and the way they commanded the ship and crew.

It’s got to be considered at least a possibility, then, that the show will continue this trend. This doesn’t mean Captain Burnham will be killed off; I’d actually argue she’s pretty safe. But there are many different routes to her potentially leaving the ship, such as a desire for freedom that we saw in Season 3, or even perhaps taking up a new, more senior role within Starfleet.

Captain Burnham in the first Season 4 trailer.

If this theory were to come to pass, it would be something I’d expect to see at the very end of the season. Even if Burnham seems 100% committed to her new role as captain, I don’t think it’s a theory we can definitively rule out.

It’s worth mentioning that at time of writing, Discovery hasn’t been officially renewed for a fifth season – so all this talk of who’ll be in the captain’s chair by then could be moot! And of course this theory has a very strong counter-argument: that Discovery’s main story arc across its first three seasons can be read as Burnham’s ascent to the captain’s chair.

Theory #4: The Spore Drive will be rolled out to more ships.

The USS Discovery making a Spore Drive jump.

The Season 3 finale rushed past this point as it had a lot going on, but the revelation that Book – and potentially millions of other people with empathic abilities – can serve in the role of Spore Drive navigator is huge. The technology was previously limited by Stamets being the only one with the ability to interface with the mycelial network, but now that limitation has seemingly been removed.

In a galaxy where dilithium supplies are still low, having a powerful alternative method of propulsion is a godsend for Starfleet, and I would think it would be a priority to start recreating the technology and training up a whole corps of Spore Drive navigators.

Book was able to use the Spore Drive in Season 3 – potentially opening it up for more ships to use.

On the production side of things, this would finally find a proper use for what has been one of Discovery’s more controversial elements. Even after the discovery of the huge dilithium cache in the Verubin Nebula, the vitally-important fuel is still a limited resource. Developing an alternative way for Starfleet ships to get around should still be a priority for the organisation.

This could be a story with real-world parallels, too. Climate change is a very real and very dangerous threat out here in the real world, and finding new, cleaner ways of generating power and fuelling our vehicles is essential. Discovery could use its Spore Drive as an analogy for the development of electric vehicles or renewable energy generation, for example.

Theory #5: Kovich works for Section 31.

Kovich in Season 3.

This is another Season 3 theory that I’m choosing to bring back! The question of who Kovich is and what role he played in Starfleet and the Federation was left open at the end of Season 3, and we know that the character will return in some capacity. As someone who seemed to talk around the issue at hand and not reveal everything he knew, Kovich strikes me as potentially being a Section 31 operative – or even the head of the organisation.

We don’t know yet if the Section 31 series that was announced in 2019 will go ahead as planned. But if it does, there could potentially be a connection between Kovich and Georgiou that would tie the two shows together. Kovich is mysterious enough that his character could be taken in many different directions – but my money’s on Section 31.

Theory #6: The ban on time travel will be explained further.

Admiral Vance first told us of the ban on time travel.

This one is a hope as much 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 #7: The Federation has flouted the ban on time travel.

HMS Bounty travels through time in Star Trek IV: The Voyage Home.

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 someone like the shadowy Kovich (who we talked about a moment ago) might have. President Rillak is someone we don’t know yet, but she could also be involved.

Obviously the bulk of the season’s story will deal with the gravitational anomaly. But there’s scope to either talk about the time travel ban in a standalone episode or even tie the two stories together – perhaps the anomaly has been unleashed as a result of unsanctioned time travel.

Theory #8: The story will connect with the Short Treks episode Calypso.

The USS Discovery seen in Calpyso.

Despite a handful of moments in Season 3 which seemed to connect to Calypso, the story of the season overall ended up going in a very different direction. While we saw a couple of things that arguably did tie in to the Short Treks episode, major things like the USS Discovery undergoing a refit have actually moved the plot even further away.

It’s possible that Calypso will forever remain an outlier in Star Trek’s canon – an episode tied to a vision of Season 2 or Season 3 that was changed before it made it to screen. But earlier in Season 3 it felt like we were getting close to seeing how it could all be tied together – and I’m hopeful that Season 4 will find a way to do so.

Theory #9: The crew will have to defend the Verubin Nebula.

The dilithium planet at the centre of the Verubin Nebula.

The Federation is in a weakened state, and even if we see worlds like Ni’Var rejoin the organisation it’s still nowhere near as powerful as it once was. The Verubin Nebula is thus a very tempting target for anyone looking to gain an edge in a galaxy where dilithium is still in short supply. As the only known significant dilithium supply, whoever controls the Verubin Nebula will have a massive tactical advantage.

We can compare the Verubin Nebula to Deep Space Nine’s Bajoran wormhole in that respect – it’s a resource of huge strategic importance. Season 3 didn’t show us much about the makeup of the galaxy’s factions outside of the rump Federation and the Emerald Chain, but it’s got to be possible that factions like the Dominion, Klingon Empire, or even the Borg still exist and would want to seize the Verubin Nebula for themselves.

The USS Discovery arriving at the Verubin Nebula in Season 3.

Season 4 has teased a scientific puzzle – the gravitational anomaly. But that doesn’t mean there won’t be villains in play, and Discovery has introduced us to several compelling and interesting villains over its first three seasons.

To make a long theory short, it would begin to stretch credulity to think that everyone in the known galaxy would see the Federation rebuilding and having access to dilithium and not want to find out for themselves what’s going on. Once the Verubin Nebula’s existence becomes known, even if the Federation promises to share its bounty with all comers, it seems very likely that someone would want to take control of the dilithium supply for themselves.

Theory #10: The super-synths from Picard Season 1 are involved with the gravitational anomaly.

The super-synths in Picard Season 1.

Picard Season 1 introduced us to a faction I nicknamed the “Mass Effect Reapers” – for their similarity to that video game faction. This race of super-synths existed outside of the Milky Way galaxy and promised to come to the aid of any synthetics who were being persecuted by organics, and Soji and Sutra attempted to contact them in the Season 1 finale.

We don’t know much at all about the super-synths or what their goals or motivations might be. It has to be considered at least possible that the attempted contact by the Coppelius synths set in motion a chain of events that could lead to the super-synths attacking the Milky Way galaxy.

Theory #11: The gravitational anomaly is a superweapon.

The USS Discovery en route to the anomaly in the second Season 4 trailer.

Based solely on what we’ve heard about the gravitational anomaly in the trailers and teasers, one thing strikes me as odd. The anomaly appears to be “targetting” the Federation. I put the word in inverted commas because it implies an intelligence at work – someone or something in control of the anomaly, directing it to attack the Federation. But what if that’s actually the case?

I mentioned the super-synths above as one possible culprit, but we could also consider factions like the Borg or the Dominion – they might have taken the opportunity of the Burn to perfect a weapon to destroy the remaining members of the Federation, perhaps as a precursor to invading and conquering the Alpha Quadrant.

A different depiction of the anomaly.

There are also factions like the Kelvan Empire from The Original Series – whose possible return to the Milky Way galaxy lines up in terms of timing. Enterprise’s Sphere Builders also come to mind: they attempted to use their own anomaly-generating devices to convert a region of space to resemble their native realm also as a precursor to invasion.

In short, are we certain that the gravitational anomaly will be nothing more than a natural phenomenon? I’m definitely not convinced of that right now! Past seasons of the show have seen twists and turns, taking stories in unexpected directions. Right now we assume that whatever this anomaly is it’s something natural – but that may not be the case.

Theory #12: Captain Burnham and the crew will encounter the Klingons.

The Klingons have been part of Discovery since the beginning.

By the late 24th Century the Federation and Klingons were firm friends, having been allied for a century and after fighting side-by-side against the Dominion. We don’t know if that alliance endured to the 32nd Century, but it’s certainly plausible to think that it did. The Klingons might even have joined the Federation at some point, and their violent warrior culture may have been significantly pacified.

One thing that could be very interesting to see is how the crew of the USS Discovery – almost all of whom are veterans of the Federation-Klingon war – would respond to that. They’ve worked alongside Klingons like L’Rell before, but many of them still see the Klingons as an old enemy. The story of overcoming that prejudice could mirror episodes like The Wounded from The Next Generation, and would be very interesting to see.

Theory #13: Some areas of the galaxy – such as the Delta Quadrant – avoided the worst effects of the Burn.

The USS Voyager was the first Federation starship to explore the Delta Quadrant.

It’s quite possible that Season 4 won’t revisit the Burn narrative in any detail. But one thing I’d be curious to see is the true extent of the disaster – did it reach all four quadrants of the galaxy equally, or did its effects fade out after a certain point? Michael Burnham discovered that the Burn had a point of origin, and that it radiated out from that point like ripples on the surface of water. Ripples eventually diminish, fading away the further they travel, and perhaps that’s true of the Burn as well. There could be whole areas of the galaxy that didn’t even notice the Burn – and maybe the ship and crew will visit one such region.

If the Delta Quadrant was left largely unscathed, for example, what might that mean for the likes of the Borg? It’s possible they aren’t even still around in the 32nd Century, but it’s also possible that they’ve had more than a century to expand and build up their forces while the Federation suffered.

Theory #14: The Guardian of Forever will be back.

Carl – the Guardian of Forever’s new persona.

Having reintroduced the Guardian of Forever in Season 3, I wouldn’t be at all surprised to see Discovery return to the Guardian’s planet in Season 4. The gravitational anomaly is something new and threatening, so it’s possible Captain Burnham might want to ask the Guardian for help or information.

The Guardian of Forever is also the only way we know of at present to travel through time – something that might be necessary if Season 4 makes an attempt to link up with Calypso in a big way. There are many reasons why Captain Burnham might want to revisit the Guardian, and it would be great to bring back actor Paul Guilfoyle, who played the Guardian’s humanoid avatar in Season 3.

Theory #15: At least one new character will join the main cast.

Lieutenant Detmer in Season 3.

One big question facing the series right now is who will take on the role of Captain Burnham’s first officer? Tilly was seen in the second trailer wearing the blue uniform of the science division, so it seems as though her tenure as the USS Discovery’s number one will be short-lived. So who will replace her? There are several secondary bridge officers like Rhys, Nilsson, and Bryce who are contenders, but it could also be someone like Lieutenant Willa – Admiral Vance’s aide-de-camp from Season 3.

A new character entirely could also join the crew, either directly as Burnham’s XO or to replace someone else who gets promoted to that role. With both Nhan and Georgiou departing in Season 3, and a potentially reduced role for Saru this time around, there’s definitely scope to bring a new major character aboard the ship.

Lieutenant Sahil was commissioned into Starfleet at the end of Season 3.

We could potentially see characters from Season 3 like Lieutenant Sahil or even Aurellio make a comeback. Sahil was the guardian of a Federation relay post who Captain Burnham met at the beginning of the season, and he was commissioned as an officer in the season finale. He would be a great choice in my opinion.

A wholly new character could also be concocted. We know that Federation President Rillak will be new for Season 4, but how significant a role she will have remains to be seen. I definitely feel that there’s scope for at least one new character – or perhaps the promotion of a secondary character to the regular cast.

So that’s it for now! Those are my official Season 4 theories written up and ready to go!

Grudge is also coming back!

The season premiere will arrive in less than a week from now, so stay tuned for a full review of the episode and an update to these theories! I wonder how many will be completely destroyed right off the bat?

I’ve been looking forward to Discovery’s fourth season all year, and it’s hard to believe it’s now only a few days away! I’m hoping to see a season of television that will be tense, exciting, and unpredictable. Despite my love of theory-crafting, I like being wrong just as much as I like being right – if not more! A story that goes in truly unexpected directions is a lot of fun, so I won’t be upset even if absolutely none of my theories come to pass.

Star Trek: Discovery Season 4 will premiere on the 18th of November 2021 on Paramount+ in the United States, and on the 19th of November 2021 on Netflix in the United Kingdom and around the world.

Star Trek: Discovery Season 4 – a wishlist

Spoiler Warning: There are spoilers ahead for Star Trek: Discovery Seasons 1-3 and the trailers and teasers for Season 4. Spoilers are also present for the following Star Trek productions: The Voyage Home, The Final Frontier, The Undiscovered Country, The Next Generation, First Contact, Voyager, Enterprise, and Picard.

Discovery’s fourth season is now less than a month away, so it’s time to look ahead. This time, though, I’m not going to be indulging in theory-crafting or even speculation… what we’re going to go through today are some of my wishes for the season. I did something similar last year in the run-up to Season 3, and if you want to see how my wishlist turned out you can find a follow-up piece I wrote after the season had aired by clicking or tapping here.

Season 3 did a reasonably good job at establishing the USS Discovery’s place in the 32nd Century, and though I have criticisms of several aspects of the Burn storyline, it was brought to a fairly conclusive end by the season finale. That should mean that the stage is set for a new story this time around, and on this occasion I’d like to lay out some of my personal preferences for Season 4 and how I’d like to see things unfold.

The USS Discovery in the Season 4 trailer.

The obvious caveat applies: I have no “insider information” and I’m not trying to claim that anything on the list below will be included in Season 4. This is merely a wishlist from a fan of Star Trek… nothing more. Everything I’m about to say is also entirely subjective! If I don’t include a point you want to see, or something I talk about sounds like something you’d hate, that’s okay. The Star Trek fandom is expansive enough for fans with all kinds of different points of view; we don’t need to fight, especially not about hypotheticals!

With all of that out of the way, let’s get into my Discovery Season 4 wishlist.

Number 1: A proper role for ex-Captain Saru that makes sense.

Saru in the Season 4 trailer.

One of the things I didn’t like about the short Season 3 epilogue at the end of That Hope Is You, Part 2 was that Saru was unceremoniously shuffled off Discovery. In order to make way for Burnham’s ascent to the captain’s chair, Captain Saru had to leave his position on the ship, and a way was found to make this plausible by giving him a deeply emotional connection to Su’Kal.

As a story point, I actually don’t fault any of that. Saru had been feeling alone and isolated with no other Kelpiens around in the 32nd Century, and his desire to help Su’Kal led to them forming a close bond. I can quite believe that he’d want to take a leave of absence to visit Kaminar and to spend more time with Su’Kal, helping him integrate into society as best he can after so long on his own.

Su’Kal and Saru in Season 3.

But unfortunately the rushed epilogue didn’t do justice to this story point, and quite frankly treated Saru with disrespect. Not since Dr Pulaski was dropped at the beginning of Season 3 of The Next Generation has a main character been handled so poorly, and I would have wanted – and expected – to see much more of a send-off for Saru. Not only had he been Discovery’s captain for all of Season 3, but he was a character we’d spent a lot of time with across Seasons 1 and 2 as well.

Season 4 will bring back Saru; he isn’t leaving the series as some folks had predicted, and I’m glad for that! But his role in Season 4 is unclear at best, and the biggest question I have is this: why does the USS Discovery need two captains on board?

Captain Saru was in command of the ship for a time.

In The Final Frontier and The Undiscovered Country, Kirk and Spock would serve on the same ship despite both holding the rank of captain, so it isn’t entirely without precedent in Starfleet for this situation to arise. In that case, though, Kirk had been demoted from the rank of Admiral, and in The Undiscovered Country in particular both officers held different positions: Kirk was in command of the Enterprise, Spock was in command of the overall mission to negotiate with the Klingons.

In short, I think the premiere of Season 4 (or whichever episode brings Saru back to the ship) needs to at least pay lip service to this point. Perhaps Saru could be given a title like “captain of the science department” in the same way as Scotty was “captain of engineering.” I wouldn’t want to see him demoted to the rank of commander – like poor Decker was in The Motion Picture! Presumably Captain Burnham has some degree of leeway when it comes to building her crew, so perhaps she’ll ask Saru to serve in a temporary role. Regardless, I hope Discovery doesn’t just ignore this point.

Number 2: Go into more detail about the ban on time travel.

The Enterprise-E approaching a temporal vortex.

The ban on time travel that was introduced in Season 3 was evidently intended to be a way for Discovery to avoid questions about how the Burn was able to happen, why Georgiou couldn’t simply return to her own time, and why the time-traveling Federation of the 29th and 30th Centuries that we’ve glimpsed in past Star Trek productions had ceased to exist. But the ban has created some storytelling issues in and of itself, and I would like Season 4 to at least try to address some of these.

Firstly, who enforces the ban? Admiral Vance seemed to imply that everyone in the galaxy – from the Emerald Chain to the Federation – simply goes along with it, but that doesn’t hold up to scrutiny. Yes, the Temporal War was certainly a bad thing. But as the war and its effects fade into memory, are we seriously supposed to believe that someone like Osyraa wouldn’t jump at the chance to use time travel to give herself and her faction an advantage? That’s to say nothing of factions like the Borg – are they signed up to the ban on time travel too?

Osyraa, head of the Emerald Chain in Season 3. She seems like someone who would use any weapon or technology at her disposal – regardless of any ban!

Even if the answer is “all pieces of time travel technology were destroyed,” that doesn’t really hold water either. It’s impossible to un-invent a powerful, weaponisable technology – as I said on several occasions during Season 3’s run! Even if everything were destroyed – something which seems like it would be impossible for every faction to prove – what’s to stop someone recreating it? The Emerald Chain had scientists like Aurellio at their disposal, and once the basic principles were understood it seems like rebuilding the technology would be a task within reach of anyone with the means and inclination.

Time travel was considered something so mundane in the 29th and 30th Centuries that its basic principles were taught in school across the Federation. Even if we discount early depictions of time travel (like the slingshot method seen in The Original Series), the fact that time travel is possible has been known to the Federation since the 22nd or 23rd Centuries at least, and even if we’re generous and say that time travel technology wasn’t “officially” invented until much later, the technology still existed for centuries prior to being banned.

The HMS Bounty was easily able to travel back in time by slingshotting around a star.

In today’s world, nuclear weapons are a comparable technology. If there were a worldwide ban on nuclear weapons, would we trust the likes of China or Russia to abide by it? Could we guarantee that every nuclear weapon was destroyed by our own governments, or might some covert hawkish faction seek to keep control of at least some of them as a contingency? In short, a ban on nuclear weapons is a noble ambition – but even in the aftermath of a nuclear war I can’t see it being workable. Even if such a ban were put in place, the weapons programmes of countries like North Korea prove that, with enough determination, anyone can recreate complex technology from scratch.

Perhaps there’s some kind of time travel arbiter that monitors the whole galaxy, and intervenes to prevent time travel from occurring. That would be one explanation. But it’s also possible that whatever this gravitational anomaly is is connected to time travel or the Temporal War – meaning Captain Burnham and the crew could be about to dive headfirst into a time travel story!

Number 3: Standalone episodes and smaller storylines to offset the main season-long arc.

The Season 3 two-parter Terra Firma was largely a standalone story.

Discovery used this formula to great effect in Season 3, which came after Seasons 1 and 2 had both leaned very heavily into serialised storytelling. I very much hope that Season 4 will continue in the same vein, because having smaller stories, character arcs, and fully standalone episodes added so much depth to the series.

We already know of one potential side-story: Adira and Gray, and in particular Gray’s quest to become corporeal again. That story has a lot of potential, and it’s actually one of the things I’m most looking forward to about Season 4. Hopefully there can be more side-stories like this, looking at other characters and taking some of our heroes to different and unexpected places.

Gray and Adira in Season 3.

Strange New Worlds has promised a return to a more episodic style of storytelling. I don’t expect that Discovery will go all-in on episodic television in the same way, not least because we already know that they have the mystery of the gravitational anomaly to solve. But I hope that, along the way, we get some detours and unconnected stories that take Captain Burnham and the ship to different places – literally and thematically.

This would be a great way for the series to show off characters who didn’t get as much to do last season, or who we haven’t spent much time with at all. Season 3 brought us an interesting story involving helm officer Keyla Detmer, and while that story wasn’t perfect it was great to spend time with a secondary character in far more detail than Discovery had ever done before. Which brings us to my next point…

Number 4: Make use of the show’s full cast – including secondary and recurring characters.

Some of the bridge crew at the end of Season 3.

As mentioned, Season 3 began this process. We got to spend more time away from Michael Burnham than Discovery had dared do in Seasons 1 or 2, and some of the episodes which placed Saru, Booker, and even Georgiou at their centre worked exceptionally well. I’d love Discovery to continue down this road, perhaps spending time with characters like Stamets – he didn’t get as much to do in Season 3 as some of the others.

With Georgiou departing for an unknown destination last year, there’s potentially space for another main cast member. We could see someone like Bryce, Rhys, or Nilsson promoted – or a character like Willa, Admiral Vance’s aide-de-camp from Season 3, join the crew. In some ways I’d like to see a new character, perhaps a 32nd Century Starfleet officer. Booker provides the crew with the viewpoint of a 32nd Century native, but he also has a different role as an outsider who isn’t a member of Starfleet. Bringing a new officer who’s native to this era aboard the ship could be an excellent move, one which could provide a lot of storytelling potential.

Detmer got her own storyline last season.

At the same time, giving more characters moments in the spotlight and their own arcs is something worth doing. We learned more about people like Owosekun, Detmer, and even Tilly in Season 3 than we ever had before, and continuing this trend by ensuring more characters get some degree of exploration is absolutely something I’d want to see.

In a season that will run for 13 episodes there’s obviously a limit; a ceiling on the number of characters and storylines that the series can fit. With that understood it obviously won’t be possible for everyone to get a fully-rounded character arc, their own storyline, and a spotlight episode putting them front-and-centre! But choosing some characters to give that amount of attention to is still important, and even those characters who don’t get a full story or their own episode this time can still have more to do than sit at their station and say “yes ma’am!”

Number 5: Bring back Nhan!

Could Nhan make a comeback?

Saru wasn’t the only character who left the USS Discovery and whose story feels incomplete. Nhan actress Rachael Ancheril was promoted to Discovery’s main cast at the beginning of Season 3 only to be shuffled off the show after only a few episodes. Nhan – the first Barzan main character in Star Trek’s history – was left behind to be the guardian of the USS Tikhov following a disaster that claimed the lives of the ship’s crew.

The Tikhov’s mission was an interesting one – it serves as a seed vault for the Federation, storing samples of plants from across the Federation and beyond. From the point of view of Nhan potentially reuniting with Burnham and the crew, though, the Tikhov was rotated between Federation member worlds, with representatives from each taking responsibility for the ship for a set period of time. Nhan seemed to suggest that she saw her mission as keeping the ship safe until the end of the Barzans’ tenure, after which it’s safe to assume the ship would be delivered to a new commander.

Nham hugs Burnham immediately before remaining behind on the USS Tikhov.

It wasn’t stated on screen how long each planet’s turn to look after the ship lasts, but that’s actually a good thing! It could be that each member world has to care for the ship for a year or two, or that it was almost the end of Barzan II’s tenure as guardians of the Tikhov – either of which could mean Nhan is almost done and could return to duty.

It was a shame that Nhan was dropped, and I don’t know if there were production-side reasons for the decision. It feels rather arbitrary, and while Nhan wouldn’t necessarily have had a huge role to play in the latter part of Season 3 she was a fun character and someone the show could and should bring back. The USS Discovery doesn’t have a permanent security or tactical officer – at least not among the main characters. Nhan could fill that role going forward, and it seems as if the ship could use a dedicated security officer based on all the scrapes that they get into!

Nhan watches the USS Discovery depart.

Nhan was also a character who provided a contrast to Michael Burnham. Where Burnham could go on emotional rollercoaster rides, Nhan was mostly stoic. And where Burnham had a loose interpretation of the rules and regulations, Nhan appeared steadfast in her dedication to Starfleet’s way of doing things.

As a character from an under-explored race, Nhan could do for the Barzans what Saru has done for the Kelpiens – showing us their history and culture in more detail. The Barzans only appeared a couple of times in Star Trek prior to Discovery, but there’s a chance for a connection with The Next Generation or to explain how they came to join the Federation – and perhaps why they chose to remain a Federation member even after the withdrawal of Earth and Ni’Var. Which brings us to the next point…

Number 6: Give us a broader look at the state of the galaxy in the 32nd Century.

A non-canon map of the galaxy.

Season 3 focused primarily on two factions: the rump Federation and the Emerald Chain. Earth, Ni’Var, and Kwejian also appeared, though the first two are ex-Federation members. We know that the Burn decimated “the galaxy” and saw many Federation members quit the organisation, but that was 125 years ago – a lot can have happened since.

Though we briefly saw Cardassians, Lurians, and a few other familiar races, we know nothing about many others. What became of the Klingon Empire? The Dominion? The Borg? Was the Burn truly galactic in scope, reaching all four quadrants in equally destructive fashion – or could some parts of the galaxy have escaped some or all of the Burn’s impact?

Are the Borg still around in the 32nd Century?

Admiral Vance told us that 38 member worlds remained in the Federation – with Earth and Ni’Var being two of the most prominent members to leave. But if the Federation had over 350 member worlds at its peak, more than 80% have quit the organisation – or been conquered, destroyed, or had some other fate befall them. Barzan II appears to remain a Federation member, as does Kaminar. It’s possible based on the Season 4 trailer that Ni’Var will rejoin the organisation – but what of the others? Who’s left in the Federation? Who quit? Who joined after the 24th Century that we might recall from past iterations of Star Trek?

Prior to the Burn, did the development of warp or transwarp speeds allow the Federation to travel further and settle other parts of the galaxy, perhaps? Could races like the Ocampa and Talaxians have joined the Federation in the Delta Quadrant, for example?

In short, the 32nd Century is a vast sandbox for the producers and writers to play in! So far we’ve only seen a tiny little corner of that sandbox – so I hope Season 4 can broaden the view and show us a bigger picture of the state of the galaxy and its factions.

Number 7: More Admiral Vance!

Admiral Vance in Season 3.

In Season 3, Admiral Vance embodied the very best of Starfleet’s values. Even though he was dealt a very bad hand in the aftermath of the Burn, he remained loyal not only to the Federation and Starfleet, but to the ideals the organisations have always stood for. Even when negotiating with Osyraa – a powerful adversary – Vance refused to compromise on his convictions.

The arrival of Rillak – a new character who will serve as the Federation’s president – could mean that Admiral Vance is sidelined. If Burnham is reporting directly to the President it seems like she’ll be going over Vance’s head, or at least around him. I guess I’m just concerned that Discovery doesn’t really have space for two “big boss” characters, and that Vance may lose out to Rillak in terms of stories and screen time.

President Rillak could occupy a very similar narrative role to Vance.

It’s possible that Rillak is being set up in a deliberately antagonistic way, and that the decision was taken to keep Vance as a more sympathetic character. I didn’t really like Rillak’s interaction with Captain Burnham in the recent Season 4 trailer, but at the same time what she had to say wasn’t too far removed from what Vance had to say at a couple of points in Season 3. He could take a tougher line with Burnham and Saru when he needed to without coming across as one of Star Trek’s typical “evil admirals!”

Actor Oded Fehr brings Vance to life and gives him a real gravitas, and there’s scope to learn more about who Vance is and what makes him tick. Vance told us he has a wife and child; perhaps we could meet them and see how he is when he’s off-duty in a more casual setting.

When Osyraa and the Emerald Chain were plotting their attack on Federation HQ in Season 3 I was genuinely worried for Admiral Vance! The Emerald Chain attack didn’t kill him off – fortunately – so he lives to fight another day! I know we’ll see him in some capacity in Season 4, but I hope he gets more to do than just chair a few meetings.

Number 8: Kill off a main character.

Who could it be?

Speaking of characters who felt at risk, Season 3 only saw the character of Ryn killed off. Ryn was a fun character for sure, and his death was very sad, but at several key moments where Discovery could have been a little bolder at swinging the proverbial axe, main characters appeared to be safe thanks to their plot armour.

The character I felt most embodied this side of Season 3 was Owosekun. In the season finale it seemed as though she was about to make the ultimate sacrifice – setting off a bomb in a low-oxygen environment – but the Sphere Data-powered DOT robots saved her life at the last minute. There were other characters in that group, including Tilly, Detmer, Bryce, and Rhys, who likewise could’ve been killed off in the season finale.

All of these characters survived last season’s finale.

I’m not arguing for any one specific character to be immediately killed off, and as I like all of the main characters for their own unique reasons any death would be a tragedy! But some stories work better or feel more impactful when the heroes lose a friend, and the Season 3 finale would have undeniably had a lot more emotional weight if someone hadn’t made it to the end.

So Season 4, here’s your challenge: kill off a main character! Let’s not repeat what happened to Nhan and Georgiou, being shuffled off the ship to some other destination. And let’s not set up a story where everyone is in danger only to have them all miraculously saved at the end. Instead let’s actually kill off a major character at the right point in the story. Doing so would raise the stakes dramatically and hammer home that whatever threat Captain Burnham and the crew are facing is genuinely deadly.

Number 9: A character crossover from a past iteration of Star Trek.

The Doctor from Voyager.

This isn’t the first time I’ve suggested this idea! But as Lower Decks has shown on several occasions, bringing back a character from Star Trek’s past can be a lot of fun – and emotional for longstanding Trekkies. Last season I suggested Voyager’s Doctor – or rather, a backup copy of him from the Season 4 episode Living Witness – as a potential character crossover, as the chances of him being alive in the 32nd Century seemed higher than most!

Given Star Trek’s technobabble, however, an excuse could be found to bring back practically anyone. Characters from Enterprise, Deep Space Nine, or even Picard could all appear in some form – through stasis or cryogenic suspension, in synthetic bodies, as holograms, trapped in transporter beams, frozen solid under the surface of an ice planet… and so on! With a little creativity, Discovery Season 4 could find a way to bring back pretty much anybody, and doing so would be absolutely wonderful.

Scotty appeared in Season 6 of The Next Generation thanks to sci-fi magic!

Aside from Voyager’s Doctor, I could suggest Enterprise’s Temporal Agent Daniels, Picard’s Soji or Deep Space Nine’s Dax symbiont as contenders for characters who could potentially have survived to the 32nd Century through “natural” means. Soji, as a character in a series running alongside Discovery, would be a fascinating choice – but at the same time I could understand if the producers don’t want to go down that route for fear of affecting or restricting future Picard stories.

If I were to fantasise I might suggest a character like Riker or Chekov. Even if they were only seen as holograms or in a recorded message I think including a “classic” character like that would mean so much to fans. We saw something comparable to this in Season 3’s Unification III, where a hologram of Spock was briefly shown. But to bring back actors like Jonathan Frakes or Walter Koenig to record even just a short message that Captain Burnham could discover would be amazing.

Number 10: Make some kind of reference to anything from Lower Decks!

Lower Decks Season 2 has just finished its run.

Lower Decks has now got two seasons under its belt, and although there were some teething problems at first caused by the lack of an international broadcast during Season 1, the show has definitely hit its stride. It would be absolutely amazing for Discovery Season 4 to so much as name-drop an event, character, or location from Lower Decks, even if it was just a throwaway line that had no bearing on the plot.

This isn’t just about fan service, either. At present, Star Trek’s shows are all split up, occupying different places and completely different time-frames. There will be a connection between Discovery and Strange New Worlds when the latter premieres next year, but there’s no chance for a significant crossover. Name-drops and references are the next best thing, and a way for the Star Trek franchise to remain connected.

Ensigns Tendi, Rutherford, Mariner, and Boimler.

Having wholly standalone shows doesn’t make a lot of sense to me. It’s certainly true that Lower Decks and Discovery are very different in terms of style, tone, and subject matter – but as two parts of a larger franchise it doesn’t hurt to find ways to connect them. For fans it’s a nice “Easter egg,” but for casual viewers these kinds of connections can be the deciding factor in choosing to check out another show!

As Star Trek fans, we need as many people engaged with as much of Star Trek as possible – it’s the only way the franchise will survive into the future. Having different shows that appeal to different audiences is a great idea in many ways; it casts a broad net and should, in theory, bring in many more viewers and subscribers. But the next step is converting fans of one series to fans of the franchise as a whole – and if there are connections between the shows, even small ones, that’ll encourage at least some viewers to try other Star Trek shows. So if Discovery Season 4 could acknowledge Lower Decks in some way, I think that would be fantastic.

Number 11: Continue the theme of rebuilding – but at a reasonable pace.

Ni’Var seems to have rejoined the Federation.

Season 3 introduced us to the galaxy a century after the Burn. This event devastated the Federation and known space, and clearly saw a major power shift with factions like the Emerald Chain gaining strength. The Burn as a storyline may be resolved, but the galaxy can’t simply be “reset” to how it used to be. An event so devastating will take a long time to recover from. Ni’Var rejoining the Federation is a great first step, but I hope Season 4 doesn’t try to rush these things.

With the gravitational anomaly seeming to be the main focus of Season 4’s story, rebuilding the Federation may take a back seat. However, I’d like to see at least some progress in this area, as it could be one of the major sources of hope and optimism in the story of the post-Burn galaxy. With the dilithium cache from the Verubin Nebula under their control, the Federation is finally in a position to rebuild what has been lost over the past century or more – and from a narrative point of view, bringing wayward planets and races together is a story worth telling.

At the same time, the story needs to acknowledge the severity of the Burn and strike the right balance when it comes to optimistically putting the pieces back together. Trying to rush this – or worse, trying to pretend that it all happened off-screen – would lead to a truly unsatisfying and unrealistic narrative.

Season 4 can’t simply pretend that the Burn is over and done with and completely move on to new stories. Even though the Burn was clearly intended as the main story of a single season, its massive implications and effects can’t be confined to Season 3 of Discovery. Any other Star Trek stories set in the 32nd Century – and beyond – will need to acknowledge the lingering effects of the Burn, and something as significant as rebuilding the Federation and bringing hope back to worlds that had lost it can’t simply be done off-screen so Captain Burnham and the crew can race away to their next big adventure.

So that’s it. A few of my hopes and wishes for the imminent fourth season of Star Trek: Discovery.

I don’t think I’d have chosen to go for another “galaxy-ending” apocalyptic threat if I’d been in charge of planning the story of Discovery Season 4. After the Klingon war in Season 1, Control and the Red Angel in Season 2, and the Burn, the collapsed Federation, and the Emerald Chain in Season 3 I would have liked to have seen Captain Burnham and the crew catch a break! Not every season has to be about the imminent destruction of the universe; stories which are smaller in scale can be just as dramatic and just as impactful when done right.

Regardless, this is the direction Discovery seems intent on going, and I’m interested to see what the gravitational anomaly is all about. I’m hopeful that Season 4 can deliver some fun, exciting, dramatic, and interesting Star Trek stories with Captain Burnham in command, and I’m very much looking forward to the new season. Even if none of my wishes are meant to be, Season 4 will undoubtedly still have plenty to offer.

Star Trek: Discovery Season 4 will premiere on Paramount+ in the United States on the 18th of November 2021. An international broadcast will follow on Netflix on the 19th of November 2021.
