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 9

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

After All In failed to move the needle in a major way, Rubicon came along! The latest episode saw a minor theory cull, with three theories being debunked – and a couple of others moving ever closer to being struck off the list! As the season builds up to its conclusion, this was bound to start happening, and I don’t lament the passing of any of the theories that didn’t pan out. We also had a rare confirmation this week, and with fewer new theories to talk about, the list will shrink for the first time in several weeks!

On reflection, perhaps I was a little harsh on Rubicon in my review. The episode was decent, but it suffered because I find myself struggling to get invested in the Book-versus-Burnham relationship squabble storyline, and that’s been a dominant force over the past couple of episodes in particular. I’m still hopeful that Discovery will find a sensible – and fairly quick – resolution to this, but at the same time I think I need to try to be less petty about it!

So let’s take a look at the confirmation and the debunkings before we jump into the main list.

Confirmed theory:
Tarka’s weapon will be successful.

Kaboom!

The obvious path for a “happily ever after” kind of story would have been for Captain Burnham and the crew to stop Book and Tarka before they had a chance to use their weapon. And, to her credit, Captain Burnham was inches away from success as she managed to talk to Book and convince him not to deploy the weapon.

But I guess that in her haste to patch things up with her boyfriend, Captain Burnham forgot about Tarka. And Book likewise didn’t make sure that Tarka was on board with his decision to wait for the communication attempt, as Tarka launched his weapon the second Book and Burnham finished their conversation.

Tarka launched his weapon.

I’m glad that the story took this route. It potentially opens up a more interesting meeting with Unknown Species 10-C, one with more tension and the possibility of conflict. But most importantly, Tarka remained true to his characterisation. He didn’t back down just because Book had a change of heart, and he wasn’t able to be persuaded by Captain Burnham’s request.

Tarka remains an interesting adversary. I don’t want to call him a “villain,” not exactly. He has a complexity and a nuance that makes his motivation understandable, even if his “ends justify the means” approach could very well lead to people getting hurt. I’m not ready for Discovery to get rid of Tarka… and I confess that I’m still rooting for him to find a way across the divide between universes.

So that theory was confirmed.

We also have several debunkings to get through, so we’ll run through those next!

Debunked theory #1:
Nhan works for Section 31.

Nhan in Rubicon.

This was a fairly straightforward one by my standards! When we saw Nhan in the promos for Rubicon, I theorised that she might be wearing a different uniform to the standard Starfleet ones worn by Captain Burnham and the crew because she had been recruited by Section 31. She could have been given a Section 31 mission aboard Discovery – perhaps connected to the DMA.

But it didn’t come to pass! Nhan works for Starfleet Security, and has spent some time as a soldier helping the Federation battle against the remaining forces of the Emerald Chain. She doesn’t appear to be making a big return to Discovery, either, merely appearing in a guest role in Rubicon.

Debunked theory #2:
Tarka will realise that there’s a tracker on the isolynium.

Tarka and Book working on the isolytic weapon.

This was another fairly simple one by my standards. In short, I speculated that Tarka would check the isolynium that Book procured and figure out that a tracking device had been placed on it. It seems like the kind of thing he might’ve done; he’s been thorough when it comes to his work, and he clearly didn’t fully trust Haz Mazaro.

But Tarka didn’t check, or if he did off-screen he didn’t find the small tracking device that Captain Burnham had placed. If this theory had panned out we could’ve seen Captain Burnham and the crew having to pick up the trail another way, or even being led into a booby-trap of Tarka’s devising! In a longer season, perhaps such a detour would have made sense. With only four episodes left, I guess wasting an episode chasing down Book and Tarka would’ve been extraneous fluff.

(Probably) debunked theory #3:
The DMA is (or was) a life-form.

The DMA in Rubicon.

It was never stated outright in clear-cut terms, but this theory now feels sufficiently unlikely that I’m striking it from the list. If the DMA was alive… it isn’t anymore! Tarka’s weapon saw to that. The arrival of a second DMA within moments of the demise of the first seems to confirm that the destructive anomaly is little more than a tool; the dredge or mining equipment that Captain Burnham and others figured out at the end of All In.

Unknown Species 10-C could still be a synthetic race, so the concept of a life-form on the scale of the DMA is still plausible in Discovery Season 4. But the DMA itself now seems certain to be little more than a tool – whoever is controlling it is the sentient one. It might’ve been interesting if the DMA had been alive, with a story similar to The Motion Picture perhaps unfolding from that premise. But now we must look to Unknown Species 10-C!

So those theories have been debunked!

Now let’s jump into the main theory list, beginning with those theories that are either new or saw movement in Rubicon. Then we’ll conclude with a few theories that are still in play, but which Rubicon didn’t touch.

Theory #1:
Unknown Species 10-C built the Galactic Barrier.

The USS Enterprise approaching the galactic barrier.

I’ve never been wild about the Galactic Barrier in Star Trek. It’s something that dates right back to the very beginning of The Original Series, but it’s always struck me as a bit of an oddity; an element of pure fantasy in a setting that prefers to base its astronomy on real science. The Galactic Barrier is also rather poorly explained, and can seemingly be ignored at the whim of Star Trek’s writers – some episodes depict crossing it as being impossible, others show starships moving through it with ease. It also feels like a 2D anachronism in the 3D realm; unless the galactic barrier is a sphere, surely flying up and over it should be possible!

But maybe we’re about to learn more about this strange phenomenon. Given their technological capabilities, it doesn’t seem impossible that Unknown Species 10-C constructed the Galactic Barrier – perhaps as a way to shield themselves from the races of the Milky Way, or perhaps to keep anyone from exploring too far and discovering their location. There are many reasons why a technologically advanced race might want to build something on this scale – and we could even learn that the harvested boronite is being used to fuel the Galactic Barrier itself.

The Enterprise-D is one of a number of vessels known to have passed through the Galactic Barrier.

One possible explanation for why Unknown Species 10-C might want to build something like the Galactic Barrier is to keep the Milky Way’s inhabitants in… but it could also be a shield designed to keep someone else out. That raises a very frightening question: what could be so powerful that a barrier is needed around the entire galaxy? And what could be so dangerous that being locked inside a galaxy with the Borg would be preferable?

With Unknown Species 10-C seemingly being very secretive, I think the idea of them building it to shield themselves is more likely… but there are definitely a lot of ways this theory could go!

Theory #2:
Someone else built the Galactic Barrier to keep Unknown Species 10-C out.

The Galactic Barrier on the USS Enterprise’s viewscreen.

If the Galactic Barrier is an artificial construct, perhaps it was created by another race or faction as a shield against Unknown Species 10-C. It could be the case that Unknown Species 10-C has used DMA technology against the Milky Way in the distant past, and some other race or faction constructed the Galactic Barrier to keep them out. If Unknown Species 10-C are belligerent and interested in conquest, it might take something on a galactic scale to keep the Milky Way safe.

The Q Continuum spring to mind as a possible candidate if the Galactic Barrier was artificially created. Admiral Vance mentioned the Q a few episodes back, saying that there hadn’t been any contact for more than 600 years. Given that the Q – or at least one member of the Continuum, at least – were very interested in the progress of races like humanity, perhaps they took a decision to “seal” the Milky Way to protect its inhabitants from Unknown Species 10-C.

Traversing the Galactic Barrier could be very dangerous…

Obviously this theory and the one above can’t both be right! And it’s a distinct possibility that the Galactic Barrier element of the story is just a convenient macguffin to blind Starfleet to Unknown Species 10-C and prevent easy travel to their region of space, dragging out the story and prolonging attempts at communication so other narrative threads could play out.

If that’s the case, we may learn nothing about the Galactic Barrier in the episodes that lie ahead! However, I still think it’s interesting to consider the possibilities, and it could be fun to finally get some more detail on this lesser-known but significant aspect of the Star Trek galaxy.

Theory #3:
Tarka’s mysterious “friend” is someone we’re already acquainted with.

At this point in the story, there’s no need to conceal the identity of Tarka’s friend – unless the revelation of this person’s identity is going to be a huge surprise. It’s possible that there is no Unknown Species 10-C, for example, and that Tarka’s friend is the one responsible – a theory we’ll look at in more detail in a moment! But it has to be considered a possibility that Tarka’s friend is someone we’ve already met, either in Discovery or in another iteration of Star Trek.

Rubicon hammered home Tarka’s desperation to reach his friend, and All In had given us a quote from Tarka about his grief at this person’s loss being unfathomable. Perhaps that was hyperbole on the part of someone very self-centred, but even so it feels like there’s more going on with this mysterious character. If there’s nothing special about them, and they’re just a brand-new character called something like Albert or Gladys, then why go to such trouble to keep their identity hidden during every conversation? It’s setting up a mystery – and for Discovery’s sake I sincerely hope it goes somewhere!

I put together a short list of possible candidates for being Tarka’s mysterious friend, and you can find it by clicking or tapping here.

Theory #4:
Unknown Species 10-C is a faction from a past iteration of Star Trek.

Could Unknown Species 10-C be the Kelvan Empire?

Rubicon didn’t do much to advance this theory – though the DMA controller seemed to bear a very superficial resemblance to omega molecules and possibly Borg tech – but comments from Discovery’s showrunner during a social media event may indicate that this theory isn’t going to pan out, despite the mysterious elements and references to past Star Trek shows scattered throughout the season. In short, Michelle Paradise spoke about “designing” Unknown Species 10-C and how they’re “unlike any species we’ve seen before.”

It’s still possible that we’re dealing with a faction like Picard Season 1’s super-synths, who were only seen on screen very briefly, or an extensive redesign of a race like the Borg to reflect centuries’ worth of technological progress. But I felt it was worth bringing this up, as it’s certainly our biggest indication to date that Unknown Species 10-C may be someone brand-new to the franchise.

Showrunner Michelle Paradise recently dropped a hint about Unknown Species 10-C.

I said last time that I was beginning to get a sense of déjà vu. Many of the suspects for Unknown Species 10-C also felt like plausible culprits for the Burn in Season 3 – and the way that storyline ultimately wrapped up was unpredictable (to say the least). As Trekkies who are invested in this fictional setting, I think there’s always going to be a desire to speculate and theorise about how big events in new stories could be connected to the elements from elsewhere in the franchise… I just hope that the ultimate reveal of Unknown Species 10-C doesn’t prove too disappointing if it has nothing to do with Star Trek’s past.

All that being said, there are still some plausible suspects, even if the DMA’s level of technology would seem to rule out many familiar races. The Borg, Enterprise’s Sphere-Builders, the extragalactic Kelvan Empire, V’Ger, Species 8472, the Q Continuum, and the Terran Empire are all high on my list! For a more detailed look at them, as well as a few less-likely contenders, check out my full list by clicking or tapping here.

Theory #5:
Book and Burnham will reconcile and get back together.

Book and Burnham are currently separated.

Although I may have been excessively critical of it at points in this week’s review, I maintain that the Book-versus-Burnham conflict isn’t one that the show needs. It’s built on very weak foundations, with both of them (and everyone else on the show) needing to be incredibly blinkered (or incredibly stupid) and not being able to recognise a very basic pathway to the “middle ground” that became the focus of Rubicon’s story.

We saw a big step toward reconciliation – at least on Book’s part – in Rubicon, when he agreed to stand down and give Burnham and Starfleet a week to attempt to make peaceful first contact and convince Unknown Species 10-C to deactivate the DMA. Book was willing to take a risk by trusting that Burnham would permit him and Tarka to go ahead with their plan at a later time… whether she would or not is unclear!

Book and Burnham in All In.

So that’s a positive step. With the detonation of Tarka’s weapon, the story could go in one of two ways from here: either Starfleet will let them off the hook, with the debate over the weapon rendered moot by the arrival of a second DMA, or Book and Tarka will have to go on the run to avoid the consequences of their actions.

I would suggest that Tarka is a valuable asset to Starfleet, and they may want to bring him back into the fold to help work on the DMA problem, the Galactic Barrier problem, and other things. Book is far less important in that regard, but as he’d indicated his willingness to stand down he may not be in as much trouble. There’s a pathway here to bring an end to this feud – and I hope Discovery takes it in the next week or two.

Theory #6:
Michael Burnham won’t remain captain of the USS Discovery.

Captain Burnham in Rubicon.

One potential way to pay off the Book-versus-Burnham storyline would be for it to lead to a significant change for Discovery’s captain. We saw in Rubicon that Burnham was unwilling to give the order that could have hurt or killed Book – even though she had been ordered to do so by Starfleet. This fundamental conflict between her romantic relationship and her duty is not new, and could potentially lead to Burnham stepping back from her role as captain of the ship.

Maybe she will have the strength to do what she believes is right during the DMA crisis, but will resign afterwards, unable to contemplate doing the same thing again and wanting to return to her simpler life with Book. This wouldn’t be a bolt from the blue, as we saw her wrangling with these feelings in Season 3.

In Season 3, Burnham had to consider whether remaining in Starfleet was right for her.

One of the unique aspects of Discovery within Star Trek’s broader canon is that the ship has been commanded by four very different individuals across its four seasons. Captain Burnham is different from Saru, Saru was different from Pike, and Pike, in turn, was different from Lorca. It has to be considered at least a possibility that the series will continue this trend.

I’m not really in favour of this, but it’s certainly interesting to consider. Now that we know that Season 5 is definitely happening, one possibility is that Captain Burnham will somehow leave the ship at or around the end of Season 4, making way for a brand-new commanding officer to take over. Because she’s been the show’s protagonist since Season 1, it seems unlikely, and the overall arc of Discovery between Season 1 and Season 3 can be read as Burnham’s redemption and ascent to the captaincy. But the show’s revolving door of captains may continue, and her conflict with Book and the difficult emotional situation it put her in could be the trigger to make this happen.

Theory #7:
Tarka will create his own DMA.

Tarka, Stamets, and Saru with the DMA model.

In The Examples, we saw Tarka – aided by Stamets – building a scale model of the DMA. Now that his plan to destroy it and seize its controller has failed, perhaps he’ll attempt to recreate the device using the knowledge he acquired. If so, he could inadvertently create a new DMA. Or, through time travel shenanigans, Tarka could turn out to be the creator of the original DMA!

Tarka’s story isn’t finished yet, and there’s still time for him to devise and enact a new plan over the course of the next few episodes. He had plans for using the DMA controller, so the next-best thing from his point of view might be to build his own version. He’s certainly clever enough – all he really needs is access to the resources to pull it off.

Theory #8:
Tarka’s friend built the DMA.

The second DMA in Rubicon.

As mentioned above, I think it’s a possibility that Tarka’s friend is directly involved with the DMA. It would explain how Tarka seems to know so much about it, even being able to recreate it on a smaller scale, as well as how he knows that it would be possible to use its power source to punch through to an alternate universe.

After all of the buildup, it’s possible that Unknown Species 10-C could turn out to be a single person: Tarka’s friend. It’s also possible that Tarka’s friend is working with Unknown Species 10-C, perhaps trying to find a way to reach Tarka across the divide between universes. There are a lot of different ways that this could pan out!

So those theories are new or saw movement this week.

Now, as I do every week, I’ll recap all of the other theories currently in play. I find it helps to keep everything in one place – it makes it easier to keep track of every theory so we can strike them off the list as we go!

Theory #9:
We haven’t seen the last of the Abronians.

I currently have four ideas for different ways that the Abronians – the non-humanoid race that Captain Burnham, Tilly, and the Qowat Milat helped save from cryo-sleep in the episode Choose To Live – could play a further role in Season 4.

Theory #9-A:
The Abronians’ homeworld was destroyed by the DMA.

Captain Burnham believes this image depicts a “supernova.”

After arriving at the Abronians’ cryo-ship, Captain Burnham found a stone carving that seemed to depict the destruction of the Abronians’ homeworld. This carving was only shown on screen briefly, but it seemed to show the planet being damaged or destroyed in a large explosion. Burnham credited the planet’s destruction to a “supernova,” and the story then raced ahead.

Considering that the main thrust of the season so far has been about the DMA, perhaps Burnham was incorrect: the Abronian homeworld was destroyed by the anomaly, not a supernova.

Theory #9-B:
The Abronians’ homeworld was on the other side of the DMA.

Abronian stasis pods.

Now that we know a little more about how the DMA works, this theory seems a little more plausible. Its powerful wormhole technology seems capable of transporting matter over many light-years, meaning it doesn’t seem to be a complete stretch to think that the Abronians may have originated in the vicinity of Unknown Species 10-C. They could even be Unknown Species 10-C!

One thing struck me as odd about the Abronians: the Federation was entirely unaware of them, despite the Abronian cryo-ship being relatively close to Federation space – such that Captain Burnham could reach it using Book’s ship in a short span of time. It’s possible that the Abronians had been asleep for millennia, unnoticed by the Federation and the wider galaxy for all that time. But it’s also at least possible that their cryo-ship is a newcomer to the area. If so, perhaps it arrived here via the DMA.

Theory #9-C:
The Abronians will return to help the Federation later in the season.

A deceased Abronian.

One of the themes of Discovery since Season 3 has been connection, including building connections between the Federation and other races and organisations. The Abronians were awoken from cryo-sleep thanks to the interventions of Captain Burnham and Tilly – at least in part – and they may seek to repay the Federation, or Captain Burnham personally, for that help.

We saw this play out last season with Ni’Var; in the season finale Ni’Var ships raced to the Federation’s aid as the Emerald Chain attacked. Perhaps the Abronians will likewise step up to help when the Federation needs allies.

Theory #9-D:
The Abronians’ moon-ship may be useful in a later story.

“That’s no moon…”

The Abronians’ cryo-ship is huge, and at least superficially seems to have the mass of a moon or small planetoid. If Captain Burnham and the crew needed a starship that large, such as to aid in the evacuation of a planet threatened by the DMA, for example, perhaps they’ll return to the Abronians and ask to borrow it.

As we saw in Choose To Live, the moon-ship was in full working order. All it needed was some extra dilithium to power up and it was perfectly capable of moving under its own power, and its computer systems were still functional. The only system that seemed to have failed was the wake-up timer! Discovery has precedent when it comes to telling seemingly one-off stories that have a pay-off later on, so watch this space. If Captain Burnham and the crew need a huge starship urgently, we may not have seen the last of the moon-ship!

Theory #10:
The Red Angel suits from Season 2 are connected to the DMA.

A Red Angel suit in Season 2.

Unknown Species 10-C seem to be responsible for building the DMA… whoever they ultimately turn out to be! But the DMA isn’t the first wormhole-creating technology that Discovery has introduced us to. The Red Angel suits in Season 2 were also capable of creating powerful wormholes… so could it be possible that Unknown Species 10-C built their device around or based on the same technology?

This revelation would greatly affect Captain Burnham, as she’d feel a degree of responsibility even though she wasn’t directly involved. It would also be the second disaster in a row (following the Burn) in which the Federation was implicated – albeit in an oblique way. I’m not convinced that Discovery will go down this route… but the similarities in the wormhole-creating technology gives me pause, at least.

Theory #11:
Saru will be given the captaincy of the USS Voyager-J.

Captain Saru in command… of a shuttle!

Saru’s future was briefly discussed before he offered to serve as Captain Burnham’s first officer in the episode Anomaly. He has already been offered a command of his own, so Starfleet clearly values his command abilities and experience. President Rillak was seen to be assessing Captain Burnham’s suitability for the captaincy of the USS Voyager-J in Kobayashi Maru… and she mentioned having a shortlist of candidates. Could Saru be on her list?

Several of the qualities that President Rillak said she was looking for in a potential captain seem to apply to Saru. He’s more level-headed, less likely to put himself in a dangerous situation, and more inclined to think of the big picture. He has a weakness when it comes to Kaminar, as we saw toward the end of Season 3, but generally speaking he isn’t someone who lets his emotions get the better of him. His wisdom and calm demeanour could be valuable in the captain’s chair of the Federation flagship. This could also set the stage for his departure from the show, or possibly even for a new show following his adventures aboard his new ship.

Theory #12:
The ban on time travel will be explained in more detail.

HMS Bounty was able to travel back in time in Star Trek IV: The Voyage Home.

This one is as much a hope as a theory right now! In short, the ban on time travel was introduced early in Season 3 primarily as a way for the writers and producers to avoid questions about why the 32nd Century was so different from how the far future had been depicted in earlier Star Trek productions, as well as to explain things like how the Burn was able to catch the Federation off-guard and why Georgiou couldn’t simply be sent back in time when she needed to.

But the ban itself raises some issues – the biggest one being the lack of detail on how it works and how something like this could possibly be enforced. As I said several times last season, it isn’t possible to just un-invent a technology so useful and powerful as time travel. Even just a few lines of dialogue going into a little more detail on the mechanisms involved in the ban would be really useful.

Theory #13:
The Federation has flouted the ban on time travel.

President Rillak may have tried to circumvent the ban if she felt doing so would be in the Federation’s interests.

Sticking with the time travel ban, another theory I had last season was that the Federation – and Section 31 in particular – might have deliberately flouted the ban and failed to abide by the rules. Someone as straight-laced and committed to Starfleet ideals as Admiral Vance is highly unlikely to have sanctioned such a move, but there are other Federation leaders – such as President Rillak – who could be implicated.

I don’t think it’s possible any more that the DMA story will be connected to the time travel ban, as I had previously proposed. But that doesn’t mean that a closer look at the ban, and the potential for the Federation to have tried to work around it, isn’t going to happen.

Theory #14:
The crew will have to defend the Verubin Nebula.

The dilithium planet is vital to the Federation.

This one is definitely hanging by a thread right now. Season 4 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 – 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 #15:
A major character will be killed off.

A Starfleet coffin seen in Deep Space Nine.

Lieutenant Tilly’s departure in All Is Possible definitely shook up the cast. And Gray’s departure in But To Connect may do so as well. However, I stand by what I said before the season aired: killing off a character can be a great way to demonstrate the dangerous nature of the circumstances that the crew have found themselves in. So far, despite tangling with the DMA on several occasions, only a couple of redshirts have lost their lives.

In Stormy Weather, Dr Pollard raced through the corridors of the USS Discovery to reach a hull breach, but she survived while a nameless redshirt was blown out into space. And in Rubicon, the shuttle mission saw Saru, Dr Culber, Rhys, and Bryce all in serious danger, but they all made it home. Moments like these can make it feel that Discovery is shielding even its minor characters with some pretty heavy plot armour, but I still feel that there’s scope to see a major character death before the season ends.

Theory #16:
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 couple of episodes, but earlier in the season we definitely saw movement in this direction.

Theory #17:
There will be a character crossover from a past iteration of Star Trek.

Star Trek has had some wonderful crossovers in the past.

Tarka’s friend could, as mentioned, be someone we’ve already met. But there are other ways to bring back a character from a past iteration of the franchise – 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 #18:
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 #19:
Tarka aims to travel to the Kelvin universe.

The USS Kelvin.

There are many parallel universes, as Tarka reminded us in But To Connect. Though Star Trek has shown us a number of different parallel universes before, the biggest one that comes to mind (aside from the Mirror Universe) is the Kelvin timeline, in which the three reboot films were set.

Now that we know a fourth Kelvin film is happening, a major link-up between the two settings could definitely be on the cards. We don’t know how far the Kelvin timeline and the prime timeline will have diverged by the 32nd Century, and whether it operates like the Mirror Universe with every character getting their own alternate counterpart. If it does, perhaps Tarka met his own Kelvin timeline counterpart and that’s how he cooked up this scheme. If the Kelvin timeline diverged significantly from the prime timeline it stands to reason that the Burn never happened there. We also got an oblique Kelvin timeline reference in Season 3 – could that have been a hint?

Theory #20:
Book will find Kyheem and Leto on the other side of the DMA.

Book with Leto and Kyheem shortly before the destruction of Kwejian.

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.

Theory #21:
The Guardian of Forever will be back.

The Guardian of Forever as it appeared in The Animated Series.

I’m close to retiring this theory. In short, I had suggested that the reintroduction of the Guardian of Forever in Season 3 could mean that we’ll encounter the timeless entity again in Season 4. It would be nice to bring back Paul Guilfoyle, who played the Guardian’s humanoid avatar in the Season 3 two-parter Terra Firma.

However, it seems as though the DMA/Unknown Species 10-C story isn’t going in that direction. It would make sense, in a way, for Captain Burnham to seek out the Guardian to ask it about the DMA and Unknown Species 10-C – it may well know something about what’s going on that could be helpful. But the best time to have done that would have been earlier in the season. There are still ways in which the Guardian of Forever could be included, though – such as Tarka attempting to use it to reach his friend – so although I’m close, I’m not dropping it just yet.

Theory #22:
President Rillak knows what the DMA is and may be implicated in its creation.

President Rillak, leader of the United Federation of Planets.

I will admit that, as things stand, President Rillak is looking less and less likely to be involved directly with Unknown Species 10-C and the DMA. But there’s still time for a connection to be revealed!

In short, President Rillak’s single-minded goal of reuniting the Federation may be well-served by providing the disparate ex-members with an enemy or a problem to stand against. The DMA has already accelerated Ni’Var’s membership, and President Rillak even got to speak with a representative from Earth in But To Connect – so if she is involved somehow, her scheme is already paying dividends. At the very least, I think it’s fair to say that this complex, somewhat Machiavellian character is not letting the crisis go to waste, and is politicking off the DMA’s trail of destruction.

President Rillak with Captain Burnham on Ni’Var.

In her dealings with Captain Burnham, I’d argue we’ve seen this Machiavellian edge to President Rillak. In the Ni’Var negotiations depicted in All Is Possible, and again for a second time in But To Connect, President Rillak used Captain Burnham to advocate positions that would’ve been politically or diplomatically difficult for her to do openly – effectively manipulating those events from behind the scenes.

In light of all of this, I would hope that Captain Burnham will tread carefully with President Rillak. She seems the type who would happily throw Burnham and the USS Discovery under the bus if it suited her political and/or diplomatic ends. If someone like that felt that unleashing the DMA, or failing to warn everyone that it was coming, would be to her advantage, I can absolutely see her seizing on that opportunity, too. There are myriad ways in which we could connect her to the DMA, even if she didn’t order its creation. She could be in cahoots with Unknown Species 10-C, she could have learned about the DMA and chosen to cover it up, or something else that she believed was in the Federation’s long-term interests.

Theory #23:
Unknown Species 10-C is extinct.

R.I.P.

Although the arrival of a second DMA may count against this theory, it’s possible that it’s some kind of automated system. With Unknown Species 10-C still being hidden and mysterious, it seems at least possible that Captain Burnham and the crew will arrive at their base to find it empty; Unknown Species 10-C may have already gone extinct.

Perhaps they went extinct recently, or perhaps it was millennia ago. The DMA might be Discovery’s equivalent of the Planet Killer from The Doomsday Machine; an automated device left behind, a warning to the real world about the dangers of some of our long-lasting environmental and technological impacts.

Is the DMA going to turn out to be similar to the Planet Killer?

The DMA could even be Unknown Species 10-C’s last-ditch effort to prevent their own extinction. Having used up their entire power supply, they had to build such an imprecise, devastating machine to harvest all of the boronite they could possibly find just to keep the lights on and their machines powered. There could be an interesting analogy there, too.

Because Unknown Species 10-C remains hidden from us going into the next episode, all sorts of possibilities remain on the table. This could certainly be a different and unexpected way to take the story, and perhaps the culmination of the plot would be more of a technological puzzle than a conflict against an adversary, with Captain Burnham leading Starfleet’s efforts to figure out Unknown Species 10-C’s technology in order to deactivate the DMA.

So that’s the main theory list!

We also have two production-side theories in play, so we’ll look at those too before we wrap things up.

Production-side theory #1:
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 #2:
Season 4 will end on a cliffhanger!

Star Trek has a long, well-established tradition of season-ending cliffhangers! There have been some truly shocking ones in the past, including The Best of Both Worlds in The Next Generation, Deep Space Nine’s Call To Arms, Equinox in Voyager… and many more! With the story of Unknown Species 10-C and the DMA slowly being unpicked, it could be the case that we’ll get a clean resolution – like we did at the end of Season 3. But it’s also possible, in my opinion, that Season 4 will end in similar fashion to Season 2 – on a major cliffhanger!

That could be because the Unknown Species 10-C story didn’t conclude, or a war with the mysterious faction is about to break out. But the Season 4 finale could also set up the beginnings of Season 5’s story, just like how the final moments of Season 1 saw Captain Pike’s Enterprise link up with the USS Discovery.

So that’s it!

The USS Discovery inside the DMA in Rubicon.

There are still some huge questions facing Discovery as we move into the final four episodes of the season. The DMA and Unknown Species 10-C storylines have to be exposed – somehow – and there’s also the question of Tarka. Will he make it across the divide to the universe he’s trying to reach? And what of Book and Burnham – will they be able to put the arguments over the DMA behind them and reconcile? The next episode will take us to The Galactic Barrier – so maybe we’ll finally get to lay eyes on Unknown Species 10-C!

Before we go, one final point. I write up these theories because I like Star Trek and I like writing. But for some folks, fan theories can hamper their enjoyment of a film or television show. It’s worth keeping in mind that most of these theories probably won’t pan out, and we have to be prepared for the fact that even the most well-constructed fan theory, no matter how fun and plausible it seems, simply won’t turn out to be true. If you find that speculating and reading theories is beginning to detract from your enjoyment of Star Trek: Discovery – or any other television show or film – it might be a good idea to take a break for a while.

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 8

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

After an unexpected sabbatical, Discovery Season 4 returned with the episode All In. If you read my review of the episode, you’ll know that I didn’t think it was the strongest one of the season so far, but it was interesting in some ways and certainly contained some excellent performances from all of its leading stars. Because All In was, in large part, a detour as Book, Burnham, Owosekun, and Tarka scrambled to get their paws on a magical macguffin molecule called isolynium, most of our big ongoing theories didn’t see significant movement this week. That said, there’s still a lot to talk about and a few updates to get through!

There are still some big open questions, and with five episodes left I’m expecting at least some of them to start moving in pretty big ways in the next week or two! For me, the biggest point of interest right now is whether the season’s big stories will connect in a major way with past iterations of Star Trek. There are a few different ways this could happen, but a big part of me suspects that, as with the Burn in Season 3, we’re going to get something altogether new.

This week we have one confirmed theory and one theory on the production side of things that I’m very pleased to see has been debunked! As always, we’ll start there before moving into the main theory list.

Confirmed theory:
The DMA isn’t a super-weapon.

Burnham, Stamets, and Rillak examine Unknown Species 10-C’s point of origin.

Although I felt that the sequence which contained this revelation was cut rather short, Captain Burnham, Stamets, Zora, and Saru managed to figure out between them what the DMA’s true purpose is. Rather than being a super-weapon, as had been originally assumed, the DMA is a glorified piece of mining equipment, or as Captain Burnham put it, a dredge.

Its purpose appears to be to scour the galaxy for the rare isotope boronite – something that was first mentioned in the Voyager Season 4 episode The Omega Directive. Boronite can be used to synthesise omega molecules – one of the most powerful substances in the known galaxy – but Unknown Species 10-C appear to be using it to power their hyperfield – a kind of forcefield or cloak which is concealing their base or star system.

The DMA’s purpose is to harvest boronite, a rare molecule first mentioned in the Voyager episode The Omega Directive.

I really like this angle. If the DMA isn’t a natural phenomenon, which it seemed to be at first, then having it be something other than a weapon adds a different dimension to the story, one which takes it away from being a fairly typical conflict into something more complex – and, I would argue, more “Star Trek.” We’ve talked about the “it was only trying to communicate!” trope in relation to the DMA before, and how misunderstandings have long been part of Star Trek’s storytelling tradition, highlighting the complexities of dealing with very different cultures and the dangers of making assumptions. This side of the story seems to be cut from the same cloth.

This also seems to rule out other theories about the DMA, such as it being an experiment gone wrong. There’s still room for further twists and turns in the DMA’s story, though, so let’s wait and see what happens, and just what purpose Unknown Species 10-C has in mind for all of this boronite!

Debunked theory:
Star Trek: Discovery isn’t going to be renewed for a fifth season.

Phew! I was getting genuinely worried when we passed the season’s halfway point with no indication of a Season 5 renewal. In past years, we’d always known either before the season kicked off or within a week or two of its premiere that the show had been renewed, so when we got further and further in with no official news – and no rumours of production starting quietly – I began to get worried for Discovery’s future.

But in January, while the show was on hiatus, ViacomCBS confirmed that Discovery will indeed get a fifth season – making it the first show since Voyager to make it that far! (Sorry, Enterprise) This is great news, because I’m not ready yet to say goodbye to Captain Burnham and the crew. There’s so much scope for more adventures in the 32nd Century, and I feel like Discovery could continue to expand and explore this setting, perhaps laying the groundwork for more 32nd Century shows.

So those theories were confirmed and debunked.

Now we can jump into the main theory list! As always, we’ll begin with those theories that are either new or that saw significant movement in All In, before rounding out the list by recapping the rest of them.

Theory #1:
Tarka will realise that there’s a tracker on the isolynium.

Captain Burnham placed a tracking device (highlighted) on the container of isolynium.

Tarka is sharp, and more than that he has access to – and the ability to build – clever pieces of tech. We saw this week that he was able to create a changeling-capturing machine out of a low-quality Devore scanner. It stands to reason he’d want to scan the isolynium that Book procured, and if he’s as thorough as we’ve seen him be so far, perhaps he’ll figure out that Captain Burnham placed a tracking device on it.

If so, the signal that Captain Burnham showed off at the end of All In may lead to a dead-end! I’m sure that the USS Discovery will catch up with Tarka and Book – if not, the story would be fairly short and boring, after all – but it may not be as simple as following the map to the cleverly-placed tracking device.

Theory #2:
Tarka’s weapon will be successful.

Isolynium – a key component of Tarka’s weapon.

President Rillak has tasked Admiral Vance and Captain Burnham with stopping Book and Tarka before they finish work on their weapon and use it against the DMA, fearing that destroying the DMA will lead to all-out war with Unknown Species 10-C. The obvious story route from here is that Captain Burnham and the crew will track them down and either talk them out of it or destroy the weapon before it can be used. But that may not be the direction that Discovery plans on taking us.

It could be more interesting in some ways if Tarka and Book succeed in their aim of launching and detonating the weapon, destroying the DMA and attracting the attention of Unknown Species 10-C. Such a highly advanced species – if they’re as advanced as everyone is assuming, anyway – would be a formidable opponent, but they could also be willing to listen to diplomatic overtures. Perhaps Tarka and Book would have to be sacrificed, imprisoned with Unknown Species 10-C as punishment for their crime.

Tarka and Book.

Speaking of diplomacy, in the mad rush to stop Book and Tarka, I certainly hope that President Rillak hasn’t forgotten about trying to contact Unknown Species 10-C. At the very least, now the Federation knows where they are they should send a message warning them of Book and Tarka’s intentions. It might have to be more of a rush job that the Federation would have preferred – but it would be better to at least make an attempt at first contact in case Captain Burnham can’t stop the weapon in time.

Discovery is definitely unpredictable right now, and I could easily see the series taking its main story to unexpected places. Book and Tarka successfully deploying their weapon would be just one example, and it could make the introduction of Unknown Species 10-C all the more intense, exciting, and edge-of-your-seat thrilling.

Theory #3:
Unknown Species 10-C is extinct.

R.I.P.

We’ll talk in a moment about what All In might mean for my Unknown Species 10-C suspects! But there’s one possibility that I hadn’t really given much thought to that suddenly came to the fore in light of the fact that Unknown Species 10-C is still a mystery and, more significantly, that Starfleet has no way of scanning their base/star system. What if Unknown Species 10-C has already gone extinct?

Perhaps they went extinct recently, or perhaps it was millennia ago. The DMA might be Discovery’s equivalent of the Planet Killer from The Doomsday Machine; an automated device left behind, a warning to the real world about the dangers of some of our long-lasting environmental and technological impacts.

Is the DMA going to turn out to be similar to the Planet Killer?

The DMA could even be Unknown Species 10-C’s last-ditch effort to prevent their own extinction. Having used up their entire power supply, they had to build such an imprecise, devastating machine to harvest all of the boronite they could possibly find just to keep the lights on and their machines powered. There could be an interesting analogy there, too.

Because Unknown Species 10-C remains hidden from us going into the next episode, all sorts of possibilities remain on the table. This could certainly be a different and unexpected way to take the story, and perhaps the culmination of the plot would be more of a technological puzzle than a conflict against an adversary, with Captain Burnham leading Starfleet’s efforts to figure out Unknown Species 10-C’s technology in order to deactivate the DMA.

Theory #4:
Nhan works for Section 31.

Nhan.

Spoiler warning for the next episode, Rubicon, but Nhan will be making a return to Discovery! I thought it was unfortunate that she was shuffled off the ship at such an early stage in Season 3; there was scope, I felt, for more Nhan stories. So it’ll be great to welcome her back to the show in just a few days’ time!

One thing struck me about Nhan based on a couple of photos that the official Star Trek social media channels released, and that’s her uniform. Nhan isn’t kitted out in the standard Season 4 Starfleet uniform that the rest of the crew wear. Hers appears to be a new variant, possibly in a similar style to Lieutenant Willa’s from Season 3. There are many possible explanations for Nhan’s uniform, including an assignment at Federation HQ or a continuation of her service aboard the USS Tikhov, but one interesting possibility comes from Nhan’s background as a security officer. Maybe she’s been recruited by the 32nd Century equivalent of Section 31.

Theory #5:
Tarka’s mysterious “friend” is someone we’re already acquainted with.

All In saw a brief conversation between Tarka and Owosekun in which the subject of his mysterious friend came up. There seems to be more going on with this character than meets the eye, though whether Tarka was being genuine in his emotional reaction isn’t 100% clear! It’s a distinct possibility that his friend is, in fact, a love interest or even a spouse, and that could certainly be an interesting development.

The fact that Discovery has gone out of its way to keep this character’s identity a mystery is interesting as well, and one reason for doing so could be that Tarka’s friend is someone who we as the audience have already met. If it wasn’t a big deal, why not just have Tarka say the individual’s name? The more appearances Tarka makes without revealing this character’s identity, the more strongly I feel that it will turn out to be someone we’ve already met.

I put together a short list of possible candidates for being Tarka’s mysterious friend, and you can find it by clicking or tapping here.

Theory #6:
Book and Burnham will get back together.

Burnham and Book in All In.

I have to be honest: I’m not interested in more Burnham Relationship Drama™. Discovery has already done this with Ash Tyler in Seasons 1-2, and it was okay then, but it’s overdone by now. I get where the central conflict with Book has come from, but I don’t feel that the show needs this additional injection of drama to make Season 4’s story work. If I were to cut one aspect of the Season 4 story that we’ve seen so far, it would be this.

So with that in mind, my hope is that the Book-Burnham feud will be brought to an end – and hopefully within the next couple of episodes. Ideally I’d like to see them get back together, although some of the things they said to each other in All In might make that more complicated. If Burnham manages to stop Book and Tarka, perhaps he’ll come around to her way of thinking. If they’re successful in using the weapon, the argument they had will become a moot point. So there are different ways this could go, but I’m hopeful that it will be resolved soon as it’s an aspect of the show that I’m really not wild about.

Theory #7:
The DMA is a life-form.

“It’s alive!”
Frankenstein (1932)

The revelation that the DMA is a mining tool or dredge would seem to make this theory a lot less likely – but I’m not yet willing to strike it from the list. There are several ways it could unfold, but one possibility is that the DMA is a self-aware piece of technology, comparable to Zora. Perhaps it’s carrying out its orders, unaware of the damage it’s doing, and will be able to be reasoned with even if Unknown Species 10-C won’t back down.

Or perhaps the DMA has gone rogue, operating without Unknown Species 10-C’s permission. That would also be an interesting angle, as it could mean that Captain Burnham and Starfleet will have to ally with Unknown Species 10-C to stop the DMA. Some aspects of this theory as I originally formulated it – such as coming to an understanding with the DMA in a story comparable to V’Ger’s in The Motion Picture – seem to be off the table entirely. But the DMA being a self-aware, conscious machine isn’t… at least, not yet!

Theory #8:
Unknown Species 10-C is a faction from a past iteration of Star Trek.

Could it be the Borg?

The revelation of the hyperfield at Unknown Species 10-C’s point of origin was an interesting one. A field that size could conceal a small star system, as Admiral Vance suggested. But it could also hide something like a huge fleet of starships – or giant mechanical aliens. In my view, there are only a few likely candidates remaining from the long list I put together before Christmas. The technology required to create the DMA and the hyperfield seem to rule out factions like the Klingons, the Gorn, and others.

But there are still some known Star Trek factions with the potential capability of building something like this. I would point to the Borg, the super-synths from Picard Season 1, Enterprise’s Sphere-Builders, the Kelvan Empire from The Original Series (who are also an extragalactic faction), and possibly others like Species 8472, V’Ger, the Q Continuum, or the Terran Empire.

How about Species 8472?

I confess that I feel a sense of déjà vu right now. In Season 3, I theorised and speculated about possible culprits behind the Burn, and a lot of the same names and factions were in the frame then, just as they are now. The Burn ultimately went in a very different and unpredictable direction, and I feel that Unknown Species 10-C could end up in a similar place as a brand-new faction altogether. Because of the mysterious nature of the story, and how long it’s been rumbling on, would that feel like an anticlimax? If Discovery encouraged fans to guess and speculate about who Unknown Species 10-C are, would it be disappointing if the answer was “someone new that you could never have guessed?” I can’t shake the feeling that it might be.

For a more detailed look at the suspects mentioned above, as well as a few less-likely contenders, check out my full list by clicking or tapping here.

Theory #9:
President Rillak knows what the DMA is and may be implicated in its creation.

President Rillak, leader of the United Federation of Planets.

I will admit that, as things stand at the end of All In, President Rillak is looking less and less likely to be involved directly with Unknown Species 10-C and the DMA. But there’s still time for a connection to be revealed!

In short, President Rillak’s single-minded goal of reuniting the Federation may be well-served by providing the disparate members with an enemy or a problem to unite against. The DMA has already accelerated Ni’Var’s membership, and President Rillak even got to speak with a representative from Earth – so if she is involved somehow, her scheme is already paying dividends. At the very least, I think it’s fair to say that this complex, somewhat Machiavellian character is not letting the crisis go to waste, and is politicking off the DMA’s trail of destruction.

President Rillak with Captain Burnham on Ni’Var.

In her dealings with Captain Burnham, I’d argue we’ve seen this Machiavellian edge to President Rillak. In the Ni’Var negotiations depicted in All Is Possible, and again for a second time in But To Connect, President Rillak used Captain Burnham to advocate positions that would’ve been politically or diplomatically difficult for her to do openly – effectively manipulating those events from behind the scenes.

In light of all of this, I would hope that Captain Burnham will tread carefully with President Rillak. She seems the type who would happily throw Burnham and the USS Discovery under the bus if it suited her political and/or diplomatic ends. If someone like that felt that unleashing the DMA, or failing to warn everyone that it was coming, would be to her advantage, I can absolutely see her seizing on that opportunity, too. There are myriad ways in which we could connect her to the DMA, even if she didn’t order its creation. She could be in cahoots with Unknown Species 10-C, she could have learned about the DMA and chosen to cover it up, or something else that she believed was in the Federation’s long-term interests.

Theory #10:
Michael Burnham won’t remain captain of the USS Discovery.

Captain Burnham.

One of the unique aspects of Discovery within Star Trek’s broader canon is that the ship has been commanded by four very different individuals across its four seasons. Captain Burnham is different from Saru, Saru was different from Pike, and Pike, in turn, was different from Lorca. It has to be considered at least a possibility – albeit a remote one, perhaps – that the series will continue this trend.

Now that we know that Season 5 is definitely happening, one possibility is that Captain Burnham will somehow leave the ship at or around the end of Season 4, making way for a brand-new commanding officer to take over. Because she’s been the show’s protagonist since Season 1, it seems unlikely, and the overall arc of Discovery between Season 1 and Season 3 can be read as Burnham’s redemption and ascent to the captaincy. But the show’s revolving door of captains may continue.

Burnham in The Examples.

I’m not really in favour of this, but it’s certainly interesting to consider. The episodes But To Connect and All In definitely showed us how conflicted Burnham feels with regards to Book; she’s torn between her duty and the person she loves. Maybe she will have the strength to do what she believes is right during the DMA crisis, but will resign afterwards, unable to contemplate doing the same thing again and wanting to return to her simpler life with Book. This wouldn’t be a bolt from the blue, as we saw her wrangling with these feelings in Season 3.

Alternatively, Burnham could be promoted, taking up a senior role within Starfleet either at Federation HQ or on a new flagship. We already know that she had been in the running for the captaincy of the USS Voyager-J, so maybe she’ll convince President Rillak, through her work on the DMA, to reconsider her for that role. In short, there are ways her departure could be handled in a way that would feel natural – just like Tilly’s departure did earlier in the season.

Theory #11:
The Guardian of Forever will be back.

The Guardian of Forever as it originally appeared.

I’m close to retiring this theory. In short, I had suggested that the reintroduction of the Guardian of Forever in Season 3 could mean that we’ll encounter the timeless entity again in Season 4. It would be nice to bring back Paul Guilfoyle, who played the Guardian’s humanoid avatar in the Season 3 two-parter Terra Firma.

However, it seems as though the DMA/Unknown Species 10-C story isn’t going in that direction. It would make sense, in a way, for Captain Burnham to seek out the Guardian to ask it about the DMA and Unknown Species 10-C – it may well know something about what’s going on that could be helpful. But the best time to have done that would have been earlier in the season. There are still ways in which the Guardian of Forever could be included, though, so although I’m close, I’m not dropping it just yet.

Theory #12:
Tarka will create his own DMA.

Tarka and Stamets with their DMA model.

In The Examples, Tarka – aided by Stamets – created a working replica of the DMA, albeit on a smaller scale. According to Reno, this recreation came very close to destroying the entire ship! Now that Tarka has isolynium, could it be possible that he will create the DMA – either intentionally or accidentally?

Because of the DMA’s wormhole technology, it doesn’t seem like too much of a stretch to think it could travel through time as well as space, meaning a possible time-loop story is on the cards. It’s got to be at least possible to think that throwing a massive bomb at the DMA could have unintended consequences – if, that is, Tarka actually intends to build a bomb! He might see the DMA’s technology and seek to replicate it, creating his own DMA as a means to break through into the parallel universe he’s aiming to reach.

Theory #13:
Tarka’s “friend” is directly involved with the DMA.

Stamets, Tarka, and Saru with the DMA model.

Though we didn’t learn a lot more about Tarka’s friend in All In, from what we do know about them – their scientific background and desire to travel to an alternate reality – they could be a candidate for building the DMA. Unknown Species 10-C could, perhaps, be a single person, or Tarka’s friend could have worked with them, trading their scientific knowledge for Unknown Species 10-C’s power-generating technology.

Like with President Rillak, there are different ways this involvement could work, and different degrees to which Tarka’s friend could be implicated. But one thing is clear: Tarka knows a lot about the DMA, probably more than he’s been willing to share. That knowledge has to have come from somewhere, right? Maybe his friend told him about this technology before they got separated.

Theory #14:
Book will find Kyheem and Leto on the other side of the DMA.

Book with Leto and Kyheem shortly before the destruction of Kwejian.

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.

So those theories are new or saw movement this week.

Now we’ll recap all of the other theories currently in play! It helps to keep the list complete and in one place, so that we can update and cross off theories as we go!

Theory #15:
Tarka aims to travel to the Kelvin universe.

This scene in Terra Firma, Part 1 referenced the Kelvin universe.

There are many parallel universes, as Tarka reminded us in But To Connect. Though Star Trek has shown us a number of different parallel universes before, the biggest one that comes to mind (aside from the Mirror Universe) is the Kelvin timeline, in which the three reboot films were set.

A fourth Kelvin film may or may not be happening, but even if it does the setting remains ripe for further exploration. We don’t know how far the Kelvin timeline and the prime timeline will have diverged, and whether it operates like the Mirror Universe with every character getting their own alternate counterpart. If it does, perhaps Tarka met his own Kelvin timeline counterpart and that’s how he cooked up this scheme. If the Kelvin timeline diverged significantly from the prime timeline it stands to reason that the Burn never happened there. We also got an oblique Kelvin timeline reference in Season 3 – could that have been a hint?

Theory #16:
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 #17:
There will be a character crossover from a past iteration of Star Trek.

Star Trek has had some wonderful crossovers in the past.

Tarka’s friend could, as mentioned, be someone we’ve already met. But there are other ways to bring back a character from a past iteration of the franchise – 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 #18:
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. It feels like a proper link-up with Calypso is edging closer week by week.

Theory #19:
A major character will be killed off.

Spock’s funeral in The Wrath of Khan.

Lieutenant Tilly’s departure in All Is Possible definitely shook up the cast. And Gray’s departure in But To Connect may do so as well. However, I stand by what I said before the season aired: killing off a character can be a great way to demonstrate the dangerous nature of the circumstances that the crew have found themselves in. So far, despite tangling with the DMA on several occasions, only a couple of redshirts have lost their lives.

In Stormy Weather, Dr Pollard raced through the corridors of the USS Discovery to reach a hull breach. Shortly after she arrived, a redshirt was blown out into space – but Dr Pollard survived. Although moments like this can make it feel that Discovery is shielding its main and secondary characters with some pretty heavy plot armour, I still feel that there’s scope to see a major character death before the season ends.

If you want to check out my pre-season “death predictions,” in which I speculated about which characters may or may not be in danger, you can find that by clicking or tapping here.

Theory #20:
The crew will have to defend the Verubin Nebula.

The dilithium planet is vital to the Federation.

Despite having grown to sixty member worlds, the Federation is still in a weakened state and isn’t yet back to full strength. 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 cache of the valuable fuel, whoever controls the Verubin Nebula will have a massive tactical advantage.

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 #21:
The ban on time travel will be explained in more detail.

The USS Enterprise was able to travel through time using the “slingshot method.”

This one is as much a hope as a theory right now! In short, the ban on time travel was introduced early in Season 3 primarily as a way for the writers and producers to avoid questions about why the 32nd Century was so different from how the far future had been depicted in earlier Star Trek productions, as well as to explain things like how the Burn was able to catch the Federation off-guard and why Georgiou couldn’t simply be sent back in time when she needed to.

But the ban itself raises some issues – the biggest one being the lack of detail on how it works and how something like this could possibly be enforced. As I said several times last season, it isn’t possible to just un-invent a technology so useful and powerful as time travel. Even just a few lines of dialogue going into a little more detail on the mechanisms involved in the ban would be really useful.

Theory #22:
The Federation has flouted the ban on time travel.

President Rillak may have tried to circumvent the ban if she felt doing so would be in the Federation’s interests.

Sticking with the time travel ban, another theory I had last season was that the Federation – and Section 31 in particular – might have deliberately flouted the ban and failed to abide by the rules. Someone as straight-laced and committed to Starfleet ideals as Admiral Vance is highly unlikely to have sanctioned such a move, but there are other Federation leaders – such as President Rillak – who could be implicated.

I don’t think it’s possible any more that the DMA story will be connected to the time travel ban, as I had previously proposed. But that doesn’t mean that a closer look at the ban, and the potential for the Federation to have tried to work around it, isn’t going to happen.

Theory #23:
Saru will be given the captaincy of the USS Voyager-J.

Captain Saru in command of the USS Discovery in Season 3.

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 #24:
The Red Angel suits from Season 2 are connected to the DMA.

Captain Burnham’s Red Angel suit at the end of Season 2.

Unknown Species 10-C seem to be responsible for building the DMA. But it 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 #25:
We haven’t seen the last of the Abronians.

I currently have four ideas for different ways that the Abronians – the non-humanoid race that Captain Burnham, Tilly, and the Qowat Milat helped save from cryo-sleep in the episode Choose To Live – could play a further role in Season 4.

Theory #25 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 25 B:
The Abronians’ homeworld was on the “other side” of the DMA.

Abronian stasis pods.

Now that we know a little more about how the DMA works, this theory seems a little more plausible. Its powerful wormhole technology seems capable of transporting matter over many light-years, meaning it doesn’t seem to be a complete stretch to think that the Abronians may have originated in the vicinity of Unknown Species 10-C. They could even be Unknown Species 10-C!

One thing struck me as odd about the Abronians: the Federation was entirely unaware of them, despite the Abronian cryo-ship being relatively close to Federation space – such that Captain Burnham could reach it using Book’s ship in a short span of time. It’s possible that the Abronians had been asleep for millennia, unnoticed by the Federation and the wider galaxy for all that time. But it’s also at least possible that their cryo-ship is a newcomer to the area. If so, perhaps it arrived here via the DMA.

Theory #25 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 #25 D:
The Abronians’ moon-ship may be useful in a later story.

“That’s no moon…”

The Abronians’ cryo-ship is huge, and at least superficially seems to have the mass of a moon or small planetoid. If Captain Burnham and the crew needed a starship that large, such as to aid in the evacuation of a planet threatened by the DMA, for example, perhaps they’ll return to the Abronians and ask to borrow it.

As we saw in Choose To Live, the moon-ship was in full working order. All it needed was some extra dilithium to power up and it was perfectly capable of moving under its own power, and its computer systems were still functional. The only system that seemed to have failed was the wake-up timer! Discovery has precedent when it comes to telling seemingly one-off stories that have a pay-off later on, so watch this space. If Captain Burnham and the crew need a huge starship urgently, we may not have seen the last of the moon-ship!

So that’s the main theory list.

There is still one production-side theory in play, so we’ll recap that now before we wrap up.

Production-side theory:
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!

So that’s it!

Owosekun in the combat arena in All In.

It’s all still to play for as we move into the final five episodes of the season. There are several key stories to find resolutions to: the DMA, Unknown Species 10-C, the Book-Burnham drama, and more. There’s also plenty of time, in five episodes, for Discovery to take off on a side-mission or two, as well as to introduce completely new and unexpected story elements. It’s even possible that Season 4 will end on a cliffhanger now that we know Season 5 is happening… so perhaps none of the big stories will be resolved until 2023. Say it ain’t so, Joe!

Before we go, one final point. I write up these theories because I like Star Trek and I like writing. But for some folks, fan theories can hamper their enjoyment of a film or television show. It’s worth keeping in mind that most of these theories probably won’t pan out, and we have to be prepared for the fact that even the most well-constructed fan theory, no matter how fun and plausible it seems, simply won’t turn out to be true. If you find that speculating and reading theories is beginning to detract from your enjoyment of Star Trek: Discovery – or any other television show or film – it might be a good idea to take a break for a while.

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 7

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

Because Discovery is currently taking an unscheduled six-week break, I was in no rush to update my theory list! The second half of Season 4 won’t air until the 10th of February (or the 11th here in the UK), so there was more time than usual to consider the implications of the most recent episode: But To Connect.

But To Connect worked well as a mid-season finale, even though some of its story points weren’t my personal favourites and some of the drama felt rather contrived. We have some interesting questions to consider about Ruon Tarka in particular, as the Risian scientist told us some very interesting and unexpected things.

This week we have three retiring theories and one confirmation. As always, we’ll look at those first before we jump into the main list.

Retired theory #1:
Dr Kovich is an agent of Section 31.

Dr Kovich.

Though Dr Kovich’s role within the hierarchy of Starfleet and the Federation is still unexplained, after But To Connect I think we can finally retire this theory – one which I’d been holding on to since we first met the character in Season 3.

Dr Kovich’s early interactions with Georgiou in particular seemed to show him as someone morally ambiguous to the point of being uncaring; he knew that Georgiou’s health was going to fail, yet did nothing to warn her or Captain Saru. Combined with his stoic demeanour and a sense that he wasn’t telling us anywhere close to everything he knew, I speculated that he could be an operative – or even the head – of shadowy organisation Section 31.

Dr Kovich’s first appearance seemed to set him up as a mysterious, morally ambiguous character – perfect for Section 31.

There was the potential for some kind of tie-in with the Section 31 series, but with that project seemingly being shelved (at least for now), that doesn’t seem like it’s a consideration for the writers and producers in charge of the overall direction of the Star Trek franchise. In fact, we haven’t seen any mention of Section 31 explicitly since Season 2.

We’ve seen Dr Kovich as a psychologist, working with Starfleet Intelligence, having a say in the running of Starfleet Academy, and now as an expert in the field of AI. Whoever he is, and whatever formal title or position he holds, I think we can finally rule out Section 31. Dr Kovich has turned out, to my surprise I must confess, to be one of the true believers in the goals and ideals of Starfleet – something he demonstrated clearly in But To Connect through his interactions with Zora and Stamets.

Retired theory #2:
Zora will go rogue.

Zora with Captain Burnham in Stormy Weather.

There is still an open question surrounding Zora’s burgeoning sentience, and what that could mean for Captain Burnham, the crew of Discovery, and indeed the rest of Starfleet. Whether this is something Season 4 will find time to tackle, or whether Zora will be dealt with in more detail on another occasion isn’t clear right now – but I think what is clear from what we heard in But To Connect is that Zora is firmly on Starfleet’s side.

Especially after Zora’s refusal to follow orders in Stormy Weather – a moment that came with a throwback to HAL 9000 from 2001: A Space Odyssey – I was somewhat nervously awaiting Zora going completely rogue, perhaps even doing something to endanger the ship and crew.

Zora in But To Connect.

Though Zora’s refusal to share the co-ordinates of the DMA’s origin seemed, at first, to confirm my suspicion that this was the direction of travel for this storyline, Discovery ended up turning it around over the course of But To Connect, reassuring Zora that she could trust the crew of Discovery, and reassuring us as the audience that our heroes can trust her as well.

This was cemented by Zora sharing the co-ordinates of the DMA’s origin, but also by Zora being given an official role as a Starfleet mission specialist – the same loophole that brought Burnham aboard the ship after her mutiny in Season 1. Zora has started the process of becoming a more significant character on the show – something that I’d like to see continue in future episodes, as I kind of like the idea of the crew and ship working in tandem. It gives me Farscape vibes!

Retired theory #3:
Captain Burnham and the crew will encounter the Klingons.

Kol, a 23rd Century Klingon leader.

If we were going to see the Klingons this season, I think the diplomatic summit in But To Connect would have been where it happened. With the DMA seeming to be of extragalactic origin, it doesn’t seem like the Klingons will turn out to be the mysterious Unknown Species 10-C, either. So I’m choosing to retire this theory for now.

I don’t know why we haven’t seen any 32nd Century Klingons since Captain Burnham and the crew arrived last season. It’s possible that Discovery’s writers feel they’ve done all they can with the faction and want to move on to other stories, but having a Klingon or two as minor characters at key moments like the diplomatic summit wouldn’t get in the way of that. So I confess that I’m not sure why we haven’t seen any Klingons lately – but it doesn’t seem like we’re going to this season.

Confirmed theory:
Captain Burnham’s war experiences from Season 1 will come into play.

Captain Burnham in But To Connect.

In But To Connect, we saw Captain Burnham arguing in favour of a less-aggressive posture toward the DMA. She drew on her own experiences with the Klingons, in part, to inform this decision. While Book and Tarka argued for attacking the DMA with their new weapon, Burnham was one of the key voices advocating for a peaceful stance and to try to make first contact with Unknown Species 10-C.

It’s reasonable to plan for worst-case scenarios, and as I argued in my review of But To Connect, the two contrasting approaches to the DMA didn’t have to be a zero-sum game. It would have been possible to take a more balanced position, as Discovery has tried to do all season long, in which the DMA-stopping weapon was built while the Federation also made an attempt at peaceful first contact. But regardless, I speculated last week that Burnham would be the one to argue for making an attempt at peaceful first contact, reminding everyone that no one currently knows what the DMA is supposed to be nor what the intentions of its creators were. And that’s pretty much what she did in But To Connect.

So those theories are done!

Now we’re going to jump into the main list, starting with a few new theories and a few theories that saw movement in But To Connect.

Theory #1:
Ruon Tarka’s mysterious “friend” is someone we’re already acquainted with.

I’m sure that’s how Tarka would’ve typed if he’d used MSN Messenger circa 2002.

Why did Ruon Tarka avoid naming his “friend” when Book asked him about it? Tarka’s friend is supposedly one of the major motivating factors in him wanting to stop the DMA – he wants to use the power source at its centre to “punch through” to a parallel universe in the hopes of meeting up with this person. But when Book asked him who this individual was, Tarka tried to ignore the question.

This could be a complete over-reach, but I wonder if the reason for the secrecy is because Tarka’s friend is someone who we as the audience are already familiar with. This could be someone from Discovery, or it could be someone from a past iteration of Star Trek. Given that Tarka wants to travel to a parallel universe, perhaps his friend is the counterpart from that universe to someone we’re familiar with.

I put together a short list of possible candidates for being Tarka’s mysterious friend, and you can find it by clicking or tapping here.

Theory #2:
Tarka aims to travel to the Kelvin universe.

The USS Kelvin, namesake of the Kelvin timeline.

There are many parallel universes, as Tarka reminded us in But To Connect. The Mirror Universe is one that we’re familiar with from Discovery and from past iterations of Star Trek – but Tarka seemed to suggest that that isn’t his destination. In addition, Dr Kovich told us in Season 3 that travel to and from the Mirror Universe is no longer possible as of the 32nd Century.

Though Star Trek has shown us a number of different parallel universes before, the other major one that comes to mind is the Kelvin timeline (also known as the “JJ-verse”) in which the three reboot films were set. 2009’s Star Trek showed us the point of divergence; the moment at which this universe and the prime timeline separated: the arrival of Nero and his attack on the USS Kelvin. Star Trek Into Darkness and Star Trek Beyond furthered our understanding of that universe somewhat.

Kirk and Spock in the Kelvin timeline.

A fourth Kelvin film may or may not be happening, but even if it does the setting remains ripe for further exploration. We don’t know how far the Kelvin timeline and the prime timeline will have diverged, and whether it operates like the Mirror Universe with every character getting their own alternate counterpart. If it does, perhaps Tarka met his own Kelvin timeline counterpart and that’s how he cooked up this scheme.

Though Tarka is correct about the multitude of different universes and realities, of all the ones we’ve spent a significant amount of time with thus far in Star Trek, the Kelvin timeline seems the most likely destination. Compared to the likes of the Mirror Universe it’s safer, and if it diverged significantly from the prime timeline it stands to reason that the Burn never happened. We also got an oblique Kelvin timeline reference in Season 3 – could that have been a hint?

Theory #3:
Tarka’s friend made the DMA.

Tarka and Stamets made a model DMA.

How does Ruon Tarka know so much about the DMA and its inner workings? It’s true that he got data from the USS Discovery’s mission, from the scans Book’s ship took, and from other sources, but even so he seems to have been able to figure out the precise mechanisms by which the DMA operates incredibly quickly. This leads me to suspect that he may know more about it than he’s willing to say.

We should acknowledge a production-side explanation here. The way Discovery Season 4 has been written and edited has seen a number of key moments in the DMA storyline blitzed through incredibly quickly. As the audience, we’ve been parachuted in just in time to see key moments: Stamets’ proto-wormhole theory, the DMA being an artificial construct, the DMA coming from outside of the galaxy, and the discovery of its origin point. The fact that these key moments happened in relatively short sequences with not a lot of setup adds to this sense that people like Tarka seem to have accumulated a lot of information about the DMA very quickly, and we should acknowledge that he claims to have been working on this problem off-screen for many weeks, if not months.

Tarka and T’Rina with a hologram of the DMA.

So there is that caveat. But something about the way Tarka stormed aboard the USS Discovery in The Examples with clear blueprints for building a scale model of the DMA did give me pause. And then in But To Connect, his plan to disable it (but not destroy it) using a very specific type of weapon also seems to have come along at a very convenient moment.

In short, I’m speculating that Tarka knows more about the DMA than he’s letting on, and that his friend may be involved in its creation. If his friend is from a parallel universe, they may have even built the DMA specifically to help Tarka travel there. In The Examples, Book accused Tarka of knowing who made the DMA, which could be a further piece of evidence.

Theory #4:
Book and Burnham will get back together.

Book and Burnham earlier in the season.

If there’s one thing that I’d cut from Season 4 it would be the unnecessary insertion of more Burnham relationship drama. After everything she went through with Ash Tyler in Seasons 1 and 2, finding a way for her to feel settled was a huge net positive for the series. She doesn’t need to have that with Book, but having established that they worked very well together as a couple, undoing that would not be my preference.

So this is as much a hope as it is a bona fide theory, but I would like very much for Book and Burnham to resolve their differences – and quickly. Whether that will come from Book realising that Tarka has manipulated him, from Burnham reaching out, from the pair finding a way to compromise… it doesn’t really matter. But I’d hope that, within an episode or two of Season 4’s return, we can put all of this nonsense to bed. Permanently.

Theory #5:
The DMA isn’t a super-weapon.

President Rillak convinced Captain Burnham to make this argument to the delegates in But To Connect.

We got a more detailed examination of this argument in But To Connect, and as mentioned it was Burnham – with no small amount of prompting from President Rillak – who led the charge.

In brief, the DMA being damaging and destructive doesn’t prove that it’s a super-weapon, even if it was artificially created. I’d add into this discussion the fact that the DMA, in all the weeks (or months) that it’s been in the Milky Way, has destroyed one planet and one small asteroid colony. If someone were using the DMA as a weapon, it seems remarkably inefficient to have harmed precisely two places in all that time.

Captain Burnham pointed out that we have no frame of reference when it comes to Unknown Species 10-C and the DMA. There’s simply no way of knowing what their intentions were by creating this anomaly, and while it could be a weapon, there’s also a chance that it isn’t. Right now, the fact that the DMA has been misunderstood feels like a distinct possibility.

Theory #6:
The DMA is a life-form.

Zora is an AI that came to life. Maybe the DMA is too?

On the other side of But To Connect we got into a complex discussion with Stamets, Dr Kovich, and the others about the nature of Zora. At what point does an artificial construct become a distinct and unique life-form? This argument had echoes of past Star Trek episodes like The Measure of a Man and Author, Author, and was interesting in its own right. But could it be laying the groundwork for something to come with the DMA?

Star Trek has shown us life-forms like V’Ger – a giant energy cloud surrounding an artificial life-form. Perhaps the DMA is something similar, and while it may have started out as a simple piece of machinery, it has since evolved into something more. Just like with Zora, perhaps part of the second half of the season will be about understanding this new form of life – and protecting it, if necessary, from the likes of Tarka.

Theory #7:
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 #8:
There will be a character crossover from a past iteration of Star Trek.

Star Trek has had some wonderful crossovers in the past.

Ruon Tarka’s friend could, as mentioned, be someone we’ve already met. But there are other ways to bring back a character from a past iteration of the franchise – 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 #9:
President Rillak knows what the DMA is and may be responsible for its creation.

President Rillak.

Although we’ve seen President Rillak working hard to unravel the DMA, I’m not ready yet to strike her (and the Federation) off my list of suspects! As we saw in But To Connect, President Rillak is very keen to see Earth (and other worlds) rejoin the Federation as quickly as possible. The DMA has facilitated greater contact between Earth and the Federation than there has been in a long time, and was also a driving force in Ni’Var rejoining. In short, if President Rillak ordered the DMA’s creation as part of a cunning plan to bring wayward ex-member worlds back into the fold… it’s working. At the very least, she isn’t letting the crisis go to waste!

I was also struck by President Rillak’s insistence on negotiating peacefully with Unknown Species 10-C. While this is perfectly in line with stated Federation values and objectives… could she have another motive? If the DMA was created by the Federation, destroying it could cause a shockwave to resonate along its wormhole and damage or even destroy the Federation facility or planet where the DMA was originally created. President Rillak’s peaceful approach may be intended to protect the people who created it – because she knows who that is.

President Rillak and Captain Burnham.

Despite her recent appearances seeming to suggest she’s firmly on Captain Burnham’s side, I see a noticeable manipulative, almost Machiavellian side to President Rillak. She’s brought Burnham on board because she believes working together is to her advantage, as she did with the Ni’Var negotiations and at the diplomatic summit. But she also used Burnham in both of those cases to advocate positions that it would be politically or diplomatically difficult for her to do openly – effectively manipulating those events from behind the scenes.

Captain Burnham needs to tread very carefully, as I firmly believe that President Rillak is someone who will happily throw her – and everyone aboard the USS Discovery – under the bus in a heartbeat if she believed doing so would advance what she considers to be the Federation’s best interests. And if she believed that the way to bring the Federation back together is to give the various independent worlds a threat that they couldn’t handle alone… well, that might just be the reason why she sought to create something like the DMA.

As stated in previous weeks, President Rillak may not have created the DMA, nor ordered its creation, but may be covering it up because it’s in the Federation’s best interests in her opinion. She may also be choosing to keep this knowledge hidden so she can continue to exploit the DMA for her own purposes.

Theory #10:
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. It feels like a proper link-up with Calypso is edging closer week by week.

So those theories are new or saw movement last week.

Now, as always, I’ll keep the theory list all in one place by recapping all of the other theories that I currently have in play for Discovery Season 4.

Theory #11:
Unknown Species 10-C is a faction from a past iteration of Star Trek.

Could Unknown Species 10-C have already appeared in Star Trek?

Despite the fact that the DMA has passed through the galactic barrier, making assumptions is dangerous! We’re only at the season’s halfway point, after all, so there’s plenty of time for twists and turns.

Based on the DMA potentially having an origin outside of the Milky Way, the three suspects that immediately spring to mind are the Kelvan Empire, the Sphere-Builders, and the super-synths from Season 1 of Star Trek: Picard. They’d all been on my list of suspects going back months, and I really feel that any one of them would make for a potentially interesting story.

I have a longer list of suspects for Unknown Species 10-C, so for a more detailed look at these three candidates – and many others – click or tap here to see the full list.

Theory #12:
A major character will be killed off.

Shaxs’ funeral in Lower Decks.

Lieutenant Tilly’s departure in All Is Possible definitely shook up the cast. And Gray’s departure in But To Connect may do so as well. However, I stand by what I said before the season aired: killing off a character can be a great way to demonstrate the dangerous nature of the circumstances that the crew have found themselves in. So far, despite tangling with the DMA on several occasions, only a couple of redshirts have lost their lives.

In Stormy Weather, Dr Pollard raced through the corridors of the USS Discovery to reach a hull breach. Shortly after she arrived, a redshirt was blown out into space – but Dr Pollard survived. Although moments like this can make it feel that Discovery is shielding its main and secondary characters with some pretty heavy plot armour, I still feel that there’s scope to see a major character death before the season ends.

If you want to check out my pre-season “death predictions,” in which I speculated about which characters may or may not be in danger, you can find that by clicking or tapping here.

Theory #13:
The Guardian of Forever will be back.

The Guardian of Forever as it appeared in The Animated Series.

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. Because Captain Burnham and the crew still don’t know much about the DMA or Unknown Species 10-C, it would make sense to at least ask the Guardian for help – maybe it has encountered this phenomenon or the people who made it before.

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 #14:
The crew will have to defend the Verubin Nebula.

The dilithium planet is vital to the Federation.

Despite having grown to sixty member worlds, the Federation is still in a weakened state and isn’t yet back to full strength. 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 cache of the valuable fuel, whoever controls the Verubin Nebula will have a massive tactical advantage.

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. This could even be the objective Unknown Species 10-C have – they may be looking for a way to control the Verubin Nebula and its supply of dilithium.

Theory #15:
The ban on time travel will be explained in more detail.

The USS Enterprise was able to travel through time using the “slingshot method.”

This one is as much a hope as a theory right now! In short, the ban on time travel was introduced early in Season 3 primarily as a way for the writers and producers to avoid questions about why the 32nd Century was so different from how the far future had been depicted in earlier Star Trek productions, as well as to explain things like how the Burn was able to catch the Federation off-guard and why Georgiou couldn’t simply be sent back in time when she needed to.

But the ban itself raises some issues – the biggest one being the lack of detail on how it works and how something like this could possibly be enforced. As I said several times last season, it isn’t possible to just un-invent a technology so useful and powerful as time travel. Even just a few lines of dialogue going into a little more detail on the mechanisms involved in the ban would be really useful.

Theory #16:
The Federation has flouted the ban on time travel.

President Rillak may have tried to circumvent the ban if she felt doing so would be in the Federation’s interests.

Sticking with the time travel ban, another theory I had last season was that the Federation – and Section 31 in particular – might have deliberately flouted the ban and failed to abide by the rules. Someone as straight-laced and committed to Starfleet ideals as Admiral Vance is highly unlikely to have sanctioned such a move, but there are other Federation leaders – such as President Rillak – who could be implicated.

Obviously the bulk of the season’s story will deal with the DMA. 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 #17:
Michael Burnham won’t remain captain of Discovery.

Captain Burnham in The Examples.

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 very different ways in which these individual captains commanded the ship and crew.

It’s got to be considered 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 on the bridge in Stormy Weather.

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 #18:
Saru will be given the captaincy of the USS Voyager-J.

Captain Saru.

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 #19:
Book will find Kyheem and Leto inside the DMA.

Book with Leto and Kyheem shortly before the destruction of Kwejian.

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. The DMA’s similarly mysterious nature raises the faint possibility that at least some of those it appears to have “killed” may not be as dead as they first appear.

This theory is, I freely admit, a bit of a long-shot. And it hinges on a fundamental question underlying the story of the season: what’s going on with the DMA? Was it designed to kill? Or is it some kind of method of faster-than-light travel, using the wormhole at its core? If it’s the latter, perhaps some of the people on Kwejian may have survived or been transported to wherever Unknown Species 10-C reside.

Theory #20:
We haven’t seen the last of the Abronians.

I currently have four ideas for different ways that the Abronians – the non-humanoid race that Captain Burnham, Tilly, and the Qowat Milat helped save from cryo-sleep in the episode Choose To Live – could play a further role in Season 4.

Theory #20a:
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 20b:
The Abronians’ homeworld was on the “other side” of the DMA.

Abronian stasis pods.

The DMA seemingly contains the technology to generate an artificial wormhole. It’s thus possible that the DMA can facilitate travel between incredibly distant locations – not only for itself, but for other starships too. The subspace tear that the DMA left behind went nowhere – but it may be possible to get “inside” the DMA itself or even use its wormhole tech to travel vast distances.

One thing struck me as odd about the Abronians: the Federation was entirely unaware of them, despite the Abronian cryo-ship being relatively close to Federation space – such that Captain Burnham could reach it using Book’s ship in a short span of time. It’s possible that the Abronians had been asleep for millennia, unnoticed by the Federation and the wider galaxy for all that time. But it’s also at least possible that their cryo-ship is a newcomer to the area. If so, perhaps it arrived here via the DMA.

Theory #20c:
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 #20d:
The Abronians’ moon-ship may be useful in a later story.

“That’s no moon…”

The Abronians’ cryo-ship is huge, and at least superficially seems to have the mass of a moon or small planetoid. If Captain Burnham and the crew needed a starship that large, such as to aid in the evacuation of a planet threatened by the DMA, for example, perhaps they’ll return to the Abronians and ask to borrow it.

As we saw in Choose To Live, the moon-ship was in full working order. All it needed was some extra dilithium to power up and it was perfectly capable of moving under its own power, and its computer systems were still functional. The only system that seemed to have failed was the wake-up timer! So if the crew are in need of a huge starship, perhaps we won’t have seen the last of the moon-ship!

Theory #21:
Captain Burnham and/or the Red Angel suits from Season 2 are connected to the DMA.

A Red Angel suit from Season 2.

Now that we know the DMA is artificial in nature, the question shifts to who built it and why. We’ve covered the idea of it being a weapon or an out-of-control experiment, as well as being a life-form in its own right. It could also be something created by the Federation. But because this is Star Trek: Discovery, a show which likes to put Captain Burnham at the centre of its stories, perhaps there’s a connection to her that we’re missing.

The Red Angel time travel suits from Season 2 were phenomenally powerful machines, capable of generating time-wormholes large enough to transport an entire starship 930 years into the future. We already know that the DMA potentially contains a synthetic wormhole, so it wouldn’t be a huge leap to connect the two. We also don’t know for certain what became of Captain Burnham’s Red Angel suit after the Season 3 premiere. There’s also the faint possibility of a parallel universe Burnham or time travelling Burnham being responsible.

Theory #22:
Ruon Tarka – perhaps aided by Book or Stamets – will create the DMA.

Stamets, Tarka, and Saru with the DMA model.

I included Tarka on my list of suspects for the creators of the DMA, but this warrants a full entry on the theory list too! In short, we saw Stamets and Ruon Tarka creating a scale model of the DMA in The Examples, and according to Reno their experiment came very close to destroying the entire ship. They were able to perfectly recreate the device at the centre of the DMA, albeit on a smaller scale – so what’s to prevent Tarka from building a full-scale replica (other than the power generation requirements)?

This theory posits that he will do exactly that – somehow – or that his experiments will set into motion a chain of events that leads to the creation of the DMA in a kind of time-loop storyline. The DMA’s wormhole-generating technology may give it the ability to travel backwards through time as well as across vast distances, so it seems technologically plausible at the very least.

The DMA.

But To Connect fleshed out Tarka a little more, giving backstory to him and a potential motive for his single-minded pursuit of the DMA. He also may know more about the anomaly than he’s letting on – including who is responsible for its creation. Regardless, Tarka has been shown as someone willing to take all kinds of risks, and it’s not impossible to think that one of his risks could backfire – creating the DMA in the process.

Personally, I find time-loop paradox storylines to be frustrating – and they can be very difficult to pull off successfully. There’s no beginning point to such a story: the DMA exists because the DMA was created because the DMA exists because the DMA was created… it’s an infinite loop. But we’ve seen Discovery tackle time travel stories like this before – and the pieces seem to be in play right now for this theory to pan out.

So that’s the main theory list.

We also have two production-side theories in play, and I’ll recap those now.

Production-side theory #1:
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 #2:
Star Trek: Discovery isn’t going to be renewed for Season 5.

Is a fifth season going to happen?

Since Discovery debuted in 2017, we’ve known well before this point in the season that the show has been renewed. This obviously isn’t one of those “I hate new Star Trek” things that we’ve seen doing the rounds online for years; I adore Discovery and genuinely want to see it continue. But it’s profoundly odd to have arrived at Season 4’s mid-season break and to still have had no announcement about Season 5. For comparison, Star Trek: Picard has been renewed for Season 3 even though Season 2 hasn’t aired yet.

I’m hopeful that this is just a blip; a temporary delay for reasons unknown, and that the show has been renewed for Season 5 already behind the scenes. However, when we look back at Star Trek productions in recent years, it was often apparent that production work was quietly ongoing even if there hadn’t been any official word from ViacomCBS. As far as we know at this stage, there’s been no pre-production work on Season 5, let alone any filming taking place in the Toronto area. The abrupt announcement that the show is taking a mid-season break could also be indicative of issues with the production.

Once again, this is a “watch this space” kind of theory. I hope I’m wrong… but the lack of any news or even any significant rumours about the show’s future is beginning to have me worried.

So that’s it.

Discovery will return in five weeks’ time.

We’ve hit the halfway point of Season 4 with a number of theories still in play! There are major questions surrounding Ruon Tarka, Cleveland Booker, the nature of the DMA, and Unknown Species 10-C in particular that all need answers when the show returns next month. It’s going to feel like a long wait!

Before we go, one final point. I write up these theories because I like Star Trek and I like writing. But for some folks, fan theories can hamper their enjoyment of a film or television show. It’s worth keeping in mind that most of these theories probably won’t pan out, and we have to be prepared for the fact that even the most well-constructed fan theory, no matter how fun and plausible it seems, simply won’t turn out to be true. If you find that speculating and reading theories is beginning to detract from your enjoyment of Star Trek: Discovery – or any other television show or film – it might be a good idea to take a break for a while.

Star Trek: Discovery Season 4 is currently on hiatus and will return on the 10th of February. The first half of 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, YouTube, and possibly other platforms in the UK, parts of Europe, and select other countries.

Star Trek: Discovery review – Season 4, Episode 7: …But to Connect

Spoiler Warning: There are spoilers ahead for Star Trek: Discovery Seasons 1-4 and Star Trek: Picard Season 1.

Sorry for being a few days late with this review! I had several other things going on this week, including my big end-of-year article, a piece looking ahead to 2022’s entertainment experiences, and finally a review of The Matrix Resurrections that I worked very hard on. I also hoped to get around to a review of the new Disney film Encanto, but that ended up taking a back seat along with this review of Discovery’s mid-season finale.

As I said last week, I wasn’t exactly thrilled with the way the mid-season break was announced. Doing so on such short notice adds to a growing sense that ViacomCBS and Paramount+ are being very poorly-managed, and while I don’t begrudge the creative team taking additional time to work on or rework episodes in the second half of the season if that work needs to be done, it raises some serious questions about the handling of the Star Trek franchise and the Paramount+ streaming service on the corporate side of things. If ViacomCBS truly aims to compete with the biggest names in streaming, nonsense like this has to stop. In addition, there are still many Trekkies and would-be viewers all around the world who can’t watch Discovery due to corporate bullshit, something else that ViacomCBS needs to fix as quickly as possible.

The opening shot of the episode.

But To Connect worked well as a mid-season finale. It was tense and had moments of high drama that demonstrated beyond any doubt that science fiction doesn’t need to drown in space battles and high-octane action to be exciting. It was also an episode that, unfortunately, made some of its moments of drama feel incredibly contrived.

After everything Michael Burnham went through in her rollercoaster relationship with Ash Tyler in Seasons 1 and 2, giving her the chance to settle down with someone like Book was an incredibly welcome change. Forcing them to go against each other – especially for a central reason that felt contrived in the extreme – would not have been my choice for the direction of their relationship. Discovery has, over the course of its three-and-a-half seasons thus far, felt a need to inject extra drama and extra conflict where none was needed, upping the character stakes to near-soap opera levels at times. Forcing Book and Burnham to work against each other is the latest example of this trend – and it’s a disappointing thing to see.

The last thing Discovery needs is more Burnham relationship drama. Let her settle down, for goodness’ sake.

Book fell under the influence of Ruon Tarka, someone who we’ll have to deal with in more detail in a moment. For now, suffice to say that Tarka pounced on Book’s emotionally compromised state, seemingly manipulating him to advocate for attacking and destroying the DMA instead of pursuing peaceful first contact with whomever created it. Tarka has his reasons for doing this – claiming he wants to preserve the DMA’s power source so he can use it for his own purposes.

Book was clearly not thinking logically – and given his grief and the external prodding by Tarka, that makes sense. But the idea that Burnham couldn’t help him push through that, especially given that the DMA is explicitly stated to not be an immediate threat to anyone, is the point that begins to stretch credulity and make this whole situation feel contrived and forced.

The DMA was not posing an active, imminent threat to anyone.

Here’s the central point: the DMA, despite its potential danger and raw power, hasn’t actually done that much damage. If we assume that Discovery Season 4 has taken place over at least a couple of months of in-universe time, which seems reasonable given how long some of the scientists seem to have been working on these problems, it’s destroyed precisely two places in that time – a rate of one per month. And aside from Kwejian, the only other place we know it’s hit was an asteroid colony with a population of a couple of thousand. The Federation and the rest of the galactic races present at the meeting clearly have time on their side: the DMA’s path doesn’t seem to be taking it near to any inhabited systems in the immediate term, and while its unpredictable nature could see it disappear and reappear somewhere more dangerous, that doesn’t seem to be its primary mission.

If the DMA were a weapon being actively controlled, it would have targeted more places by now, so the Federation’s plan to attempt to contact its creators makes far more sense than attacking it. Even if Book couldn’t understand that at first, being blinded by his grief or desire for revenge, surely of all people Burnham would have been able to convince him to see the logic behind this slower, calmer approach. If the DMA had been actively threatening a planet – especially a named world that we as the audience might be familiar with, such as Betazed or Sigma Draconis III – things would be different. But without that desperate and immediate need to stop another disaster, the rational approach is to try to contact Unknown Species 10-C.

Book fell under the sway of Ruon Tarka – someone who clearly has his own agenda.

Earlier in the season, we saw Burnham advocate a compromise position, and But To Connect should have offered another opportunity to do so: building the weapon capable of destroying the DMA before attempting first contact. If the DMA then changes course and presents an active threat, it can be destroyed. And in addition, having the weapon in reserve while making first contact would be a valuable asset. If Unknown Species 10-C won’t see reason, the weapon could be a threat. If there’s no one there to negotiate with, the DMA could be destroyed. In short, the answer to the pretty basic problem that the episode posed isn’t “do one or the other,” it should have been “do both.” Build the weapon as a back-up while preparing for first contact.

If Discovery hadn’t insisted on themes of compromise across its last two seasons, I guess I’d give it a pass on this false choice. But in context, it seems to run counter to much of what the show has been trying to say for at least the last two years: that there are always solutions to or ways around these kinds of conflicts. The question of how to approach the DMA did not need to be a zero-sum game, and someone like Captain Burnham should have realised that – even if Book couldn’t.

This didn’t need to be a “black or white” choice. Compromise should have been possible; this is a major theme that the show has tried to present all season long.

Not for the first time, I’m left with a sense that Discovery’s writers and producers have a definite goal in mind; an endgame for the story and characters. But they haven’t figured out how to reach that finishing point in a clear and consistent manner, leaving this side of But To Connect feeling contrived.

On the flip side, the speeches that both Book and Burnham gave were very emotional, and I can’t fault the performances of either Sonequa Martin-Green or David Ajala. Both came across as two people trying to do what they genuinely believed was the right thing; conflicted because of what it would mean for their relationship, but determined to press ahead regardless. Although this wouldn’t be the way I would have chosen to handle either character, there can be no denying that the performances were exquisite.

Both actors played their roles exceptionally well.

Also on this side of the story we had a muted role for President Rillak. Though she was on Burnham’s side – wanting to advocate for an attempt at peaceful contact – she chose to recuse herself from the debate, serving as a moderator only. I still get the sense that she has schemes in play – bringing Burnham along as an ally being one of the ways she tried to manipulate proceedings to get her way without being openly involved – but it was interesting to see her in a more centrist, unaffiliated role.

Among her ambitions from the diplomatic summit were showing the Federation as taking the lead in the fight against the DMA, but also opening initial channels to United Earth with a view to bringing the isolationist world back into the fold. We’ve seen a slight softening of Earth’s leadership since Burnham helped reunite Earth and Titan in Season 3, and it was nice to welcome back Phumzile Sitole as the newly-promoted General Ndoye. As a Trekkie, I want more than anything to see Earth rejoin the Federation – but only if it feels right. Earth shouldn’t be manipulated into coming back into the organisation, so this story beat will have to be handled delicately.

General Ndoye represented Earth and Titan at the diplomatic summit.

Ruon Tarka was perhaps the most surprising character in But To Connect. His self-assured cockiness was still there from his role in The Examples, but we got an idea of what could be driving him forward, and where his interest in the DMA may have come from. Stating that he wants to cross over into a parallel universe was certainly not something I expected – but at the same time it felt very familiar, and very Star Trek.

Tarka comes across as somewhat similar to Tolian Soran, the villain from Star Trek: Generations. Soran wanted to return to the Nexus – a paradise-like realm contained inside of an energy ribbon that periodically transited the galaxy. Tarka’s desire to enter the DMA and use its powerful controller to “punch through” to a parallel universe where he expected life to be better is at least somewhat comparable – and his willingness to break the rules and work against Starfleet shows the same kind of single-mindedness that Soran demonstrated.

Tarka is determined to use the DMA controller for his own ends.

We’ll save for my theory post a full discussion of Tarka, his possible motivations, and potential destinations. But suffice to say this character turn has piqued my curiosity. There’s the potential to get a more complex presentation of a “mad scientist” character trope, one which gives him an understandable or even sympathetic motive for his actions. I don’t think we’re at that point yet, but I see potential in this storyline.

Shawn Doyle was wonderful in The Examples, making Tarka stand out as a different take on a character archetype that has appeared on a number of prior occasions in Star Trek. This amazing performance continued in But To Connect, and Doyle deserves a lot of credit for the way he brought the character to screen with complexity – especially given the relatively small amount of screen time that Tarka has had in the season so far.

Tarka and Book formed an unlikely alliance.

As has happened several times already this season, though, Discovery quickly glossed over much of the actual work on the problems and puzzles posed by the DMA in order to get to the dramatic stand-off between Book and Burnham. Tarka’s weapon seemed to come out of nowhere, and although he’s clearly spent weeks or months of off-screen time working on it, in the episode itself it seemed to be a bolt from the blue; almost a deus ex machina solution to the threat posed by the DMA. As I’ve said on several occasions this season, the end result isn’t the problem – it’s that we as the audience really needed to see at least some of the process to get there, even if just by way of something like a montage.

In exactly the same way on the other side of the story, Zora’s discovery of the coordinates of the DMA’s origin was completely blitzed through in order to get to the story that the episode really wanted to tell. When it comes to the DMA, which is the season’s “big bad” at least thus far, Discovery has dedicated precious little time to actually dealing with it head-on, with much of the investigation happening off-screen. As the audience, we’ve been parachuted in just in time to see key moments: Stamets’ proto-wormhole theory, the DMA being an artificial construct, the DMA coming from outside of the galaxy, and now finally the discovery of its origin point. All of these points, so incredibly vital to the story of the DMA, feel like they’re scarcely even footnotes in a story which on the surface should be making more of them.

Captain Burnham, Stamets, and Adira listen to Zora as she refuses to share what she’s learned.

Before anyone jumps in to tell me off for missing the point: I get it. Discovery has other stories to tell, and wants to use this season in particular to look at issues surrounding trauma and grief. Practically all of the main characters seem to embody different responses to trauma: Stamets getting lost in his work, Culber desperately trying to help others even if doing so is at his own expense, Book’s journey through the stages of grief, and Tilly’s career switch all come from that same thematic place. And these individual, character-centric stories are absolutely worth telling. However, in a sci-fi series that also has the DMA as a major plotline, it feels that the first half of Season 4 has prioritised these character moments at the expense of this other major narrative. It should’ve been possible to balance the season’s story to give both appropriate weight and screen time – but Discovery has yet to find that balance.

So let’s tackle Zora next. The USS Discovery’s computer-AI-Sphere data hybrid has been developing slowly since Season 3, and until the very end of The Examples a couple of weeks ago felt like a relatively minor part of the season. Her transformation into basically an additional main character has been an interesting one, and this week was by far Zora’s biggest moment centre-stage. I got echoes of a number of past Star Trek stories – from The Ultimate Computer and The Measure of a Man through to Picard Season 1’s dealings with the synths and Data – in the way Zora was analysed and discussed by Dr Kovich, Dr Culber, Stamets, Adira, and Gray. It was an incredibly honest and frank discussion, one which absolutely embodied the spirit of Star Trek.

Zora’s status and rights were discussed in But To Connect.

Through this side of the story, But To Connect gave us by far the best and most sympathetic presentation of Dr Kovich. I maintain that, based on his earlier appearances, some kind of Section 31 or spy role was a possibility – and maybe that was the original intention for the character when he was created in Season 3. In But To Connect, however, we saw Dr Kovich as a firm believer in the values and ideals of Starfleet and the Federation: determined to seek out new life, and to ensure that very different forms of life have the same rights as everyone else.

Stamets also shone on this side of the story, and the writing here showed off a complexity that the relatively short half-episode runtime could have hampered. Stamets’ attitude toward Zora’s newly developed sentience could have come across badly, making him out to be some kind of “AI-phobe,” in the vein of something like Picard Season 1’s Zhat Vash. However, the way Stamets was handled – aided greatly by a wonderful performance from Anthony Rapp – ensured that we could understand his reservations and concerns without seeing him as some kind of futuristic bigot.

Anthony Rapp gave his best performance of the season so far.

As in All Is Possible, Discovery succeeded at taking a complex argument and ensuring that the views on both sides were sensible and understandable, allowing true understanding and trust to be reached. Likewise this week, Stamets didn’t simply try to put his foot down and declare that the existence of Zora was some kind of horrible, insurmountable problem, and nor did Zora attack Stamets or try to shut down his concerns.

In an increasingly polarised political climate here in the west, where politicians and activists on all sides are increasingly dogmatic and unwilling to listen to opposing points of view, Discovery once again showed us how debate and discussion should be handled: calmly, maturely, and with mutual respect. This is one of the lessons from this season of the show: that we can’t simply write off points of view we disagree with, nor should we try to shut down or dismiss them. Listening is the first step toward understanding.

Despite the stakes and the complexity of the arguments, But To Connect showed us how these kinds of conversations can and should be handled.

From my perspective as someone who’s non-binary, I felt there could be echoes of the real-world conversation surrounding transgender and non-binary folks in the way Zora’s movement toward acceptance was handled. There are many people who are dismissive of trans and non-binary people – something I sadly experienced firsthand recently in a conversation with someone I considered a friend. An unwillingness to listen and a desire to be dismissive of something we personally don’t understand is always going to be a temptation – but Stamets found that, by having a frank and honest conversation, his fears and concerns could be allayed.

There’s been a lot of debate around transgender and non-binary rights in recent years, and the issues of sex, gender, and gender identity have become highly politicised. Zora was struggling to find acceptance in But To Connect, and I felt that the show was perhaps drawing on the trans inclusion discussion for inspiration in this particular storyline. Speaking from a personal perspective, it isn’t easy to figure oneself out. To then present oneself to one’s friends only to be rejected is a horrible feeling – and I’m glad that Zora’s friends were able to remain on her side, even if they had questions about her at first.

It felt like the conversation with Zora may have had a real-world inspiration.

The Zora conversation also tackled the real-world issue of artificial intelligence and the growing impact of machine learning, algorithms, and AI on our daily lives. Star Trek has depicted “evil” AIs on several occasions, including in Season 2 of Discovery, so to take a break from that negative portrayal and to find a way to show AI in a positive light was a welcome change. I’m no longer convinced, for example, that we’ll see Zora go rogue or act against the crew’s wishes later in the season or in future stories; her status as a bona fide member of the crew feels settled.

Stamets was part of that, and voiced his concerns with eloquence before coming around to accepting Zora’s place in the crew. Dr Culber played a role too, as did Gray and Adira. It was very cathartic, after Stamets missed the entirety of Gray’s incorporation a few episodes ago, to see the two characters having the chance to interact. Gray’s future on the show is now uncertain following his departure with Guardian Xi bound for Trill, so it was even more important to give him and Stamets some small crumbs of screen time together.

It was great to finally see Stamets interacting with Gray and Adira.

In a very real sense, But To Connect felt like two distinct episodes haphazardly bolted together. In a longer season, both the conflict at the diplomatic summit and Zora’s moves toward sentience could have been explored while also giving more time to the likes of Tarka and his efforts to untangle the mysteries posed by the DMA. But because Discovery wanted to make a point – not a bad point, I concede – about Starfleet seeking out new life, we got both stories squashed down into the runtime of a single episode. Neither of these stories were bad, nor was the link between them, but the conflict at the summit in particular would have benefitted from additional development, and the incredibly minor side-story about Tarka and the DMA could have been fleshed out a lot more – as could Stamets, Adira, and Zora’s work to find the coordinates.

The similarities between the stories of Zora and the DMA would’ve still worked had they been longer or spread across two episodes, and I guess my big criticism of But To Connect isn’t that I hated or even disliked either, it’s that I would’ve liked to have seen a longer, perhaps slower-paced, version of them. Cutting the conflict between Book and Burnham – or finding a way to resolve it – would also have been a preference.

T’Rina and Tarka view a holo-model of the DMA.

But To Connect told two stories about seeking out new life: the very core of Starfleet’s mission. Zora’s story was the better of the two; it had more nuance, better characterisation, and a truly sympathetic presentation of both sides of the discussion. It dealt with incredibly deep and complex themes in an understandable way, giving rise to a conclusion that felt natural, but most importantly that felt earned.

The diplomatic summit, meanwhile, took what could have been a similar setup but presented it as a false “either-or” choice – a choice that, I would argue, felt unnecessary and thus contrived. Its conclusion, instead of being one that promoted understanding and dialogue, ended with one side claiming total victory and the other suffering defeat. This laid the groundwork for Book and Tarka’s rebellion – stealing a spore drive prototype and flying away to attack the DMA. That ending may have been a natural or inescapable one given the setup, but it didn’t need to be – and it seems to run counter to some very timely and important allegories that Discovery has tried to include this season.

Burnham casting her vote.

A few scattered final thoughts: Discovery seems to be going down the route of some of the ’80s Star Trek films by depicting interesting-looking background aliens… then giving them nothing to do nor even naming them. It would be nice to learn more about some of the galaxy’s races, but just dropping them in the background doesn’t feel like a particularly good way to handle things. The music in But To Connect was probably the best of the season so far, and the score used during the voting scenes in particular was incredibly tense – perfectly complimenting what was happening on screen.

Why does Burnham get a vote? I can understand why each Federation member world might get an individual vote, but giving everyone present the chance to vote could disproportionately favour one side. It feels like it was there for another moment of drama rather than because it makes sense in context.

We saw a full-blooded Cardassian, a Ferengi, and several other familiar races – including one who may be a Xindi. Missing from the summit, however, were races like the Klingons and factions like the Dominion. It’s possible that there have been major structural changes to those governments, or that diplomatic relations with the Federation are poor. Discovery may also be avoiding their use with a view to bringing them back in a future story – or to give room for the likes of Picard or Strange New Worlds to include these factions.

This character was a callback to the events of Kobayashi Maru.

Stamets flipping the issue of trust onto Zora was a clever one, and a great rhetorical way to begin to bring that argument to a close. Dr Kovich’s line that Stamets could have been reassigned if he couldn’t work with Zora was clever – but then who would have operated the Spore Drive? Saru and T’Rina make an adorable couple, and although I wouldn’t consider either Doug Jones or Tara Rosling to be “old,” it was still sweet to see Discovery giving screen time to a burgeoning romance between two people who aren’t 25 any more!

So I think that’s about all I have to say for now. Stay tuned, because later in the week I’ll be writing up my theories for the second half of the season. It’s only six weeks, but I really can’t wait to find out what happens next! The DMA and Unknown Species 10-C still present wonderful mysteries, and although my head says what we’ll ultimately get will be something brand-new to the franchise, my heart is still hopeful that there’ll be some kind of big connection or callback to a past iteration of Star Trek!

Star Trek: Discovery theories – week 6

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

Stormy Weather does, on the surface at least, appear to have narrowed things down as Discovery approaches its unexpected mid-season break. As we’re barely at the halfway point, though, I’m not convinced that everything is as it seems! There are many possible explanations for the DMA having passed through the galactic barrier, and despite the assertions from some characters that Unknown Species 10-C must be someone that the Federation has “never encountered before,” there are still several highly plausible culprits who could be responsible!

So let’s jump into the theory list. At this stage, the list is actually fairly static. Stormy Weather didn’t confirm or debunk anything from previous weeks, and I’ve really just got one new theory – one that isn’t even connected to the events of the episode! However, several theories have seen movement, and while some may be close to being debunked I’m not ready just yet to strike off any of them.

Theory #1:
Captain Burnham’s war experiences from Season 1 will come into play.

Michael Burnham in Season 1.

At the beginning of Season 1, Michael Burnham made a series of mistakes (to put it mildly). Though she wasn’t responsible for the outbreak of war between the Federation and Klingon Empire, she was blamed for it for a long time. Her aggressive actions toward the Klingons, wanting to fire the first shot in a very un-Starfleet manner, proved to be a very costly learning experience for her. Having seen three-and-a-half seasons of growth and development since, I’m sure Captain Burnham has taken those lessons to heart.

Starfleet is currently assuming that the DMA is a weapon and that whoever created it has hostile intentions. That seems reasonable, and it’s sensible in many ways to plan for worst-case scenarios. But an aggressive faction building a super-weapon is only one potential explanation for the existence of the DMA – and someone like Captain Burnham, who once made the mistake of being too aggressive in the face of the unknown, seems well-placed to argue for a mission of first contact rather than jumping straight into a war.

In short, my theory is that Captain Burnham will be one of the main voices arguing for a less aggressive posture when investigating the DMA, reminding the likes of Admiral Vance and President Rillak that we simply don’t know what the DMA is or what it was intended to be.

Theory #2:
Zora will go rogue.

Zora and Captain Burnham in Stormy Weather.

This week we got to see more of Zora than we ever have before. At one point she did refuse to follow an order, but thanks to interventions from Gray and Captain Burnham, this was resolved. Zora didn’t “go rogue” in Stormy Weather; she was suffering emotionally as a result of the difficult situation she was in. Having only just become aware of her own emotions, she was in a very difficult and traumatic situation. But there may be more to come.

The dangerous nature of artificial intelligence has been a theme Star Trek has returned to time and again since The Original Series episode The Ultimate Computer all the way back in 1968. But recent iterations of Star Trek in particular have used narratives involving evil or out-of-control AIs and synthetic life several times: there were the rogue synths and the super-synths in Star Trek: Picard’s first season, and in Discovery’s second season we had the Control AI.

It’s at least possible that an emotionally-compromised Zora would go rogue, acting against the wishes or even orders of Captain Burnham and the crew. Though Zora professes to care about the crew of Discovery, her instinct for self-preservation in the face of a dangerous situation may kick in.

Theory #3:
The DMA isn’t a super-weapon.

What is the DMA?

In Stormy Weather we learned that the DMA has passed through the galactic barrier – meaning that it quite likely originated from outside of the Milky Way galaxy. That isn’t a given, but it’s a reasonable assumption based on the available evidence.

The fact that the DMA is artificial in nature doesn’t mean it was intended to be a weapon, though, despite its harmful effects in the Milky Way galaxy. It’s possible that extragalactic exploration had been done in a big way by the 32nd Century, but missions that took Starfleet crews outside of the galaxy are incredibly rare within Star Trek. In short, we know precious little about the universe beyond the barrier, meaning that whoever created the DMA is a complete unknown quantity.

Discovery feels like it’s building up to some big reveal about the DMA and Unknown Species 10-C, and one way that could go would be for the crew to learn that the DMA isn’t what they have been assuming. The biggest possibility, given what we learned in Season 3 about the lack of dilithium, could be that the DMA represents an experiment in faster-than-light travel that went awry.

Theory #4:
The DMA is a life-form.

The USS Enterprise inside V’Ger.

The DMA’s extragalactic origin could be an indication that at its core is a sentient life-form, something akin to V’Ger from The Motion Picture. If that were the case it may not be attacking anyone, but simply exploring or trying to make contact. After all, “they were only trying to communicate” has become a Star Trek trope at this point!

Star Trek has shown us many different forms of synthetic life over the years, and while the DMA would certainly be one of the most unusual, it wouldn’t be entirely without precedent. Seeking out new life is at the very core of Starfleet’s mission, and finding a way to communicate with the DMA and figure out what it wants or needs could be a very interesting story – one about understanding and bridging the chasm between different cultures and societies that Star Trek has always done so well.

Theory #5:
Unknown Species 10-C is a faction from a past iteration of Star Trek.

Could Unknown Species 10-C have already appeared in Star Trek?

Despite the fact that the DMA has passed through the galactic barrier, making assumptions is dangerous! We’re barely halfway through the season, after all, so there’s plenty of time for twists and turns. While this revelation has made a handful of suspects significantly more likely than others, in my opinion practically all of the candidates remain in play at this stage.

Based on the DMA potentially having an origin outside of the Milky Way, the three suspects that immediately spring to mind are the Kelvan Empire, the Sphere-Builders, and the super-synths from Season 1 of Star Trek: Picard. They’d all been on my list of suspects going back months, and I really feel that any one of them would make for a potentially interesting story.

I have a longer list of suspects for Unknown Species 10-C, so for a more detailed look at these three candidates – and many others – click or tap here to see the full list.

Theory #6:
A major character will be killed off.

Two “dead” officers.

Lieutenant Tilly’s departure in All Is Possible has certainly shaken up the cast. However, I stand by what I said before the season aired: killing off a character can be a great way to demonstrate the dangerous nature of the circumstances that the crew have found themselves in. So far, despite tangling with the DMA on several occasions, only a couple of redshirts have lost their lives.

In Stormy Weather, Dr Pollard raced through the corridors of the USS Discovery to reach a hull breach. Shortly after she arrived, a redshirt was blown out into space – but Dr Pollard survived. Although moments like this can make it feel that Discovery is shielding its main and secondary characters with some pretty heavy plot armour, I still feel that there’s scope to see a major character death before the season ends.

If you want to check out my pre-season “death predictions,” in which I speculated about which characters may or may not be in danger, you can find that by clicking or tapping here.

So those theories saw some movement this week.

As I said, there really hasn’t been a great deal going on on my theory list in the aftermath of Stormy Weather! But as always, we’ll keep the entire list in one place by re-stating the rest of the theories that I currently have in play.

Theory #7:
The Guardian of Forever will be back.

The Guardian of Forever as it appeared in The Animated Series.

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. Because Captain Burnham and the crew still know so very little about the DMA, it would make sense to at least ask the Guardian for help – maybe it has encountered this phenomenon before.

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 #8:
Some areas of the galaxy – such as the Delta Quadrant – avoided the worst effects of the Burn.

Stamets with a holographic galaxy map in The Examples.

Season 4 touched briefly on the Burn with Su’Kal and Saru in Kobayashi Maru, and last season’s big story may not return in any significant way now that the DMA is out there. 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. To see a full write-up of this theory, click or tap here.

Theory #9:
Captain Burnham and the crew will encounter the Klingons.

Kol, a 23rd Century Klingon leader.

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 #10:
The crew will have to defend the Verubin Nebula.

The dilithium planet is vital to the Federation.

The Federation is still in a weakened state, 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.

Another view of the planet in the Verubin Nebula.

Season 4 has presented Captain Burnham and the crew with a scientific puzzle: the DMA. 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 #11:
The ban on time travel will be explained in more detail.

HMS Bounty was able to travel back in time.

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 #12:
The Federation has flouted the ban on time travel.

President Rillak may have tried to circumvent the ban if she felt doing so would be in the Federation’s interest.

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 might have. President Rillak could also be involved.

Obviously the bulk of the season’s story will deal with the DMA. 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 #13:
Michael Burnham won’t remain captain of Discovery.

Burnham in the captain’s chair.

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 very different ways in which these individual captains 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 All Is Possible.

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 #14:
There will be a character crossover from a past iteration of Star Trek.

Soji could potentially still be alive in the 32nd Century.

This theory returns from Season 3, where I doggedly clung to it for the entire season!

Discovery’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!

There were several great crossovers during The Next Generation era.

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 #15:
Saru will be given the captaincy of the USS Voyager-J.

Captain Saru.

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 #16:
Book will find Kyheem and Leto inside 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. We don’t know what the DMA is yet; one of my very early pre-season theories involved the Nexus, but that seems to be debunked already! However, the anomaly’s mysterious nature raises the faint possibility that at least some of those it appears to have “killed” may not be as dead as they first appear.

This theory is, I freely admit, a bit of a long-shot. And it hinges on a fundamental question underlying the story of the season: what’s going on with the DMA? Is it a super-weapon designed to be destructive? Or does it perhaps contain a wormhole, portal, or gateway to some other place? If it’s the latter, perhaps Kyheem, Leto, and others from Kwejian might still be alive.

Theory #17:
We haven’t seen the last of the Abronians.

I currently have four ideas for different ways that the Abronians – the non-humanoid race that Captain Burnham, Tilly, and the Qowat Milat helped save from cryo-sleep in the episode Choose To Live – could play a further role in Season 4.

Theory #17a:
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 #17b:
The Abronians’ homeworld was on the “other side” of the DMA.

Abronian stasis pods.

Stamets and Tarka believe that the DMA contains the technology to generate an artificial wormhole. It’s thus possible that the DMA can facilitate travel between incredibly distant locations – not only for itself, but for other starships too. The subspace tear that the DMA left behind went nowhere – but it may be possible to get “inside” the DMA itself or even use its wormhole tech to travel vast distances.

One thing struck me as odd about the Abronians: the Federation was entirely unaware of them, despite the Abronian cryo-ship being relatively close to Federation space – such that Captain Burnham could reach it using Book’s ship in a short span of time. It’s possible that the Abronians had been asleep for millennia, unnoticed by the Federation and the wider galaxy for all that time. But it’s also at least possible that their cryo-ship is a newcomer to the area. If so, perhaps it arrived here via the DMA.

Theory #17c:
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 #17d:
The Abronians’ moon-ship may be useful in a later story.

“That’s no moon…”

At this stage I can’t envision precisely what use Captain Burnham and the crew might have for a moon-sized starship… but that doesn’t mean such a need won’t arise! The Abronians’ cryo-ship is huge, and at least superficially seems to have the mass of a moon or small planetoid. If Captain Burnham and the crew needed something that large for some purpose, perhaps they’ll return and either take it or negotiate for it.

As we saw in Choose To Live, the moon-ship was in full working order. All it needed was some extra dilithium to power up and it was perfectly capable of moving under its own power, and its computer systems were still functional. The only system that seemed to have failed was the wake-up timer! So if – for reasons yet unknown – the crew need a huge starship, perhaps we won’t have seen the last of the moon-ship!

Theory #18:
Stamets and Ruon Tarka will create the DMA.

Stamets, Tarka, and Saru with the DMA model.

I included Stamets and Tarka on my list of suspects for the creators of the DMA, but they warrant a full entry on the theory list too! In short, we saw Stamets and Ruon Tarka creating a scale model of the DMA in The Examples, and according to Reno their experiment came very close to destroying the entire ship. They were able to perfectly recreate the device at the centre of the DMA, albeit on a smaller scale – so what’s to prevent them from building a full-scale replica (other than the power generation requirements)?

This theory posits that they will do exactly that – somehow – or that their experiments will set into motion a chain of events that leads to the creation of the DMA in a kind of time-loop storyline. The DMA’s wormhole-generating technology may give it the ability to travel backwards through time as well as across vast distances, so it seems technologically plausible at the very least.

Tarka and Stamets working on their model.

Ruon Tarka was shown as impatient in The Examples, and in his single-minded pursuit of the DMA he may be willing to take risks – perhaps risks which ultimately lead to the creation of the very anomaly he’s been investigating. How such a story would conclude is up in the air, but I don’t think we can rule it out as a possibility right now.

Personally, I find time-loop paradox storylines to be frustrating – and they can be very difficult to pull off successfully. There’s no beginning point to such a story: the DMA exists because the DMA was created because the DMA exists because the DMA was created… it’s an infinite loop. But we’ve seen Discovery tackle time travel stories like this before – and the pieces seem to be in play right now for this story.

Theory #19:
President Rillak knows what the DMA is and may be responsible for its creation.

President Rillak in Kobayashi Maru.

We haven’t seen President Rillak for a couple of weeks now, though she has been briefly mentioned. But when I think about the possible suspects for creating the DMA, the Federation – and by extension, President Rillak – are unquestionably on that list.

President Rillak is a cunning, almost Machiavellian politician, willing to do anything to advance what she considers to be the best interests of the Federation. I believe Captain Burnham needs to be very careful with President Rillak. During the events of All Is Possible, working with Captain Burnham was advantageous to the Federation’s president – but I have no doubt that she’d throw Burnham and the USS Discovery under the bus without so much as blinking if she believed it would be to her advantage. Which brings us to the DMA.

President Rillak might know more about the DMA than she’s currently letting on. If the Federation had created a weapon like this, or if it was an experiment gone wrong, covering it up might be her objective even if she wasn’t necessarily the one who ordered the DMA’s creation. Also, with the goal of reuniting the Federation foremost in her mind, President Rillak may prove to be the sort of uncompromising politician who’d willingly unleash destruction upon the galaxy if she believed that doing so would serve a greater purpose.

Theory #20:
Dr Kovich is an agent (or the head) of Section 31.

Dr Kovich in The Examples.

I freely admit that this theory is barely clinging on right now, but I don’t believe it’s been completely disproven just yet! The questions of who Dr Kovich is and what exactly his role is within Starfleet and/or the Federation have no clear answer right now. He’s clearly someone with power and influence, as we’ve seen him working with Admiral Vance and seemingly being able to appoint anyone he chooses to be an instructor at Starfleet Academy. Yet he also seems to have some medical training, serving as a psychologist or counsellor – and it’s in this capacity that we saw him most recently.

Because of the unclear nature of his role and the mysterious, stoic presentation from David Cronenberg, Dr Kovich is still an enigma. He’s also the kind of man who could potentially be an agent of Section 31. If it turns out that the Federation, President Rillak, and/or Section 31 are involved with the DMA, perhaps we’ll learn that Dr Kovich is as well. Or perhaps such a storyline will finally put this theory to bed once and for all!

Theory #21:
Captain Burnham and/or the Red Angel suits from Season 2 are connected to the DMA.

A Red Angel suit from Season 2.

Now that we know the DMA is artificial in nature, the question shifts to who built it and why. We’ve covered the idea of it being a weapon or an out-of-control experiment, as well as being a life-form in its own right. It could also be the responsibility of Section 31 or the Federation. But because this is Star Trek: Discovery, a show which likes to put Captain Burnham at the centre of its stories, perhaps there’s a connection to her that we’re missing.

The Red Angel time travel suits from Season 2 were phenomenally powerful machines, capable of generating time-wormholes large enough to transport an entire starship 930 years into the future. We already know that the DMA potentially contains a synthetic wormhole, so it wouldn’t be a huge leap to connect the two. We also don’t know for certain what became of Captain Burnham’s Red Angel suit after the Season 3 premiere. There’s also the faint possibility of a parallel universe Burnham or time travelling Burnham being responsible.

Theory #22:
The story will connect with the Short Treks episode Calypso.

The USS Discovery as seen in Calypso.

Stormy Weather picked up the storyline from The Examples regarding Zora’s emotions, and I would argue that the way Zora was depicted is now much closer to the way she was in Calypso. In that Short Treks episode, Zora was definitely someone who could feel emotions, so the confirmation of that now means that Calypso is, in some ways, one step nearer.

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. Despite Zora getting some development in The Examples and Stormy Weather, I can’t yet see a pathway to making Discovery and Calypso line up – but that doesn’t mean it won’t happen!

So that’s the main theory list.

We also have two production-side theories in play, and I’ll recap those now.

Production-side theory #1:
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. But that doesn’t mean she will be a main character on the show going forward, and her departure feels 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 #2:
Star Trek: Discovery isn’t going to be renewed for Season 5.

Is a fifth season going to happen?

Since Discovery debuted in 2017, we’ve known well before this point in the season that the show has been renewed. This obviously isn’t one of those “I hate new Star Trek” things that we’ve seen doing the rounds online for years; I adore Discovery and genuinely want to see it continue. But it’s profoundly odd to be nearing the halfway point of Season 4 and to still have had no announcement about Season 5. For comparison, Star Trek: Picard has been renewed for Season 3 even though Season 2 won’t air until next year!

I’m hopeful that this is just a blip; a temporary delay for reasons unknown, and that the show has been renewed for Season 5 already behind-the-scenes. However, when we look back at Star Trek productions in recent years, it was often apparent that production work was quietly ongoing even if there hadn’t been any official word from ViacomCBS. As far as we know at this stage, there’s been no pre-production work on Season 5, let alone any filming taking place in the Toronto area. The abrupt announcement that the show is taking a mid-season break could also be indicative of issues behind-the-scenes.

Once again this is a “watch this space” kind of theory. I hope I’m wrong… but the lack of any news or even any significant rumours about the show’s future is beginning to have me worried.

So that’s it.

The USS Discovery inside the void.

We have quite a few theories still in play as we approach the mid-season break. I confess that I have some expectations that this week’s episode – titled But To Connect – will move the needle on at least some of them! A mid-season finale should be a spectacle, ending on a cliffhanger or some explosive revelation to keep us as the audience on the edge of our seats. So perhaps this time next week we’ll be debunking and adding a few more theories than we did on this occasion!

Before we go, one final point. I write up these theories because I like Star Trek and I like writing. But for some folks, fan theories can hamper their enjoyment of a film or television show. It’s worth keeping in mind that most of these theories probably won’t pan out, and we have to be prepared for the fact that even the most well-constructed fan theory, no matter how fun and plausible it seems, simply won’t turn out to be true. If you find that speculating and reading theories is beginning to detract from your enjoyment of Star Trek: Discovery – or any other television show or film – it might be a good idea to take a break for a while.

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, and possibly other platforms in the UK, parts of Europe, and select other countries.

Star Trek: Discovery theories – week 5

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

After a couple of weeks where Discovery took character-focused detours, The Examples brought the story right back to the DMA – the dark matter anomaly that’s wreaking havoc across the galaxy. We learned something incredibly significant this week that will most likely have a huge impact on the season’s main storyline… but is everything as it seems?

The biggest question I have right now is about Unknown Species 10-C. Who could they be? And are they a faction we’ve encountered in a past iteration of Star Trek? My heart wants to say they’re someone familiar; that all of the callbacks and references we’ve had in Season 4 so far are building to some kind of big reveal. But my head says “no” – Unknown Species 10-C will turn out to be someone new and unpredictable.

But enough about that for now! We have several theories that were advanced by The Examples this week, as well as one that was debunked and one that was at least partially confirmed. So let’s take a look at those and then get into the main list!

Debunked theory:
Dr Culber will tell Stamets that he needs to slow down.

Stamets and Culber in The Examples.

This one surprised me by being a complete inversion of what I was expecting! After Stamets had seemingly gotten lost in his work, overworking himself desperately trying to figure out the DMA, I felt sure that Dr Culber would have something to say. In Choose To Live, Stamets missed out on Gray’s incorporation, and wasn’t there to support Adira. In All Is Possible, he missed out on talking with Tilly before she left the ship.

I felt that Stamets perhaps needed someone – particularly the man he loves – to intervene and warn him about the dangers of overworking and the family moments he’s been missing. Instead it was Stamets who helped Dr Culber: Discovery’s doctor has been throwing himself into his work, too, neglecting his own mental health for the sake of his patients. It was a neat reversal of a storyline I was expecting – and I think we’ll see more in this vein from Stamets and Culber before the end of the season.

Confirmed theory:
The DMA is a super-weapon.

The moment at which the DMA’s artificial nature was confirmed.

Though it was arguably a conclusion that was arrived at too quickly near the beginning of The Examples, Stamets and Captain Burnham confirmed – thanks to some help from Zora – that the DMA is not a natural phenomenon. Though a natural disaster would have been an interesting story in itself, this always felt like the direction of travel for Discovery, so I wasn’t exactly stunned to learn this!

At present, Captain Burnham and Starfleet are working on the assumption that the DMA is a super-weapon – something I’d been predicting ever since we first heard that some kind of anomaly was going to be a major part of Season 4. Right now, that seems like a logical assumption – and it may very well be true. But as we’ll discuss in a moment, even though the assumption right now is that the DMA is a super-weapon, that may not actually prove to be the case. I can think of several ways in which the DMA could be artificial yet not a weapon! But for now, since Captain Burnham, Admiral Vance, and everyone else on the show are content to assume it’s a super-weapon of some kind, I’m calling this theory confirmed!

So those theories were debunked and confirmed.

Now we’ll get into the main list, beginning with the theories that are either brand-new or which saw significant movement in The Examples.

Theory #1:
The story will connect with the Short Treks episode Calypso.

The USS Discovery in Calypso.

This week we got a few lines from Zora – the USS Discovery’s shipboard AI that we first met in Calypso. Zora was involved in confirming the DMA’s artificial nature, but later in the episode we got something far more significant thanks to a short conversation with Captain Burnham: Zora has begun to experience emotions.

In Calypso, Zora was definitely an emotional life-form, so this evolution in their (her?) personality is a significant step toward Calypso – and one that I hadn’t really considered until after it had happened. Until now, the Zora aboard the USS Discovery had been different from the Zora we’d met in Calypso, but after this week’s episode we’re a big step closer to reconciling the two presentations of the character.

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. Despite all that, however, a connection is one step closer today than it was last week.

Theory #2:
Zora will go rogue.

Zora.

Sticking with Zora, their newfound emotions are a very interesting – and somewhat alarming – addition to the season’s storyline. When Data first installed his emotion chip in Generations, he found the new emotions overwhelming and impossible to cope with at first – could something similar be about to happen to Zora? Will they fail the crew at a key moment? Even worse, might Zora go rogue and become a villain?

The dangerous nature of artificial intelligence has been a theme Star Trek has returned to time and again since The Original Series episode The Ultimate Computer all the way back in 1968. But recent iterations of Star Trek in particular have used narratives involving evil or out-of-control AIs and synthetic life several times: there were the rogue synths and the super-synths in Star Trek: Picard’s first season, and in Discovery’s second season we had the Control AI.

Zora told Captain Burnham of a “recent development” in The Examples.

Captain Burnham seemed concerned at Zora’s newfound emotions, but had other things on her mind so didn’t have time to deal with it then and there. What might be even more concerning, though, is the fact that Zora chose to conceal that fact for a time, choosing not to share their most recent evolution.

Perhaps a storyline like this would feel repetitive coming after Season 2 had to deal with Control. But I think it could be made to work, and it could even be made to fit in with Calypso with a bit of creative writing! Whether this theory comes to pass or not, though, I think we’re going to see something significant from Zora before the end of Season 4.

Theory #3:
The DMA isn’t a super-weapon.

The DMA as seen in Anomaly.

Okay, I know! I just said that the DMA is a super-weapon and patted myself on the back for successfully predicting that story beat months ago! But here’s the thing… the DMA being artificial in nature doesn’t mean that it’s a weapon, despite the assumptions made by Captain Burnham, Admiral Vance, and others.

The DMA could be an out-of-control experiment, perhaps something designed to allow faster-than-light travel without the need for dilithium. Stamets and Ruon Tarka suspect that it possesses the technology to create a synthetic wormhole, something that could be very useful for travelling in a dilithium-poor galaxy.

An accident or an experiment gone wrong would set up a very different kind of story to a super-weapon, one that would replace a villainous adversary with a puzzle of a scientific nature. That could be a fun and interesting way for the season to go – not to mention that it would be subversive and challenging to the audience’s expectations.

Theory #4:
The DMA is a life-form.

The USS Enterprise and V’Ger in The Motion Picture.

The DMA could also turn out to be a life-form in its own right, perhaps a synthetic one or something akin to The Motion Picture’s V’Ger. If that were the case it may not be attacking anyone, but simply exploring or trying to make contact. After all, “they were only trying to communicate” has become a Star Trek trope at this point!

Star Trek has shown us many different forms of synthetic life over the years, and while the DMA would certainly be one of the most unusual, it wouldn’t be entirely without precedent. Seeking out new life is at the very core of Starfleet’s mission, and finding a way to communicate with the DMA and figure out what it wants or needs could be a very interesting story – one about understanding and bridging the chasm between different cultures and societies that Star Trek has always done so well.

Theory #5:
Unknown Species 10-C is a faction from a past iteration of Star Trek.

Could the Borg have built the DMA?

Regardless of the intention behind the DMA, it does indeed appear to be an artificial construct. Whoever created it had a reason for doing so, even if that reason isn’t clear right now! But who could be responsible?

I recently put together a list of suspects, and I strongly encourage you to check out the full list by clicking or tapping here.

If you don’t have time for that, here’s the condensed version: the Borg, the Sphere-Builders from Enterprise, the super-synths from Picard Season 1, the Kelvan Empire, Section 31, and Species 8472 are just some of the possible culprits. For a more detailed version, check out the full list linked above.

Theory #6:
President Rillak knows what the DMA is and may be responsible for its creation.

President Rillak in Kobayashi Maru.

We didn’t see President Rillak this week, though she was briefly mentioned by Admiral Vance. But when I think about the possible suspects for creating the DMA, the Federation – and by extension, President Rillak – are unquestionably on that list.

President Rillak is a cunning, almost Machiavellian politician, willing to do anything to advance what she considers to be the best interests of the Federation. I believe Captain Burnham needs to be very careful with President Rillak. During the events of All Is Possible, working with Captain Burnham was advantageous to the Federation’s president – but I have no doubt that she’d throw Burnham and the USS Discovery under the bus without so much as blinking if she believed it would be to her advantage. Which brings us to the DMA.

President Rillak might know more about the DMA than she’s currently letting on. If the Federation had created a weapon like this, or if it was an experiment gone wrong, covering it up might be her objective even if she wasn’t necessarily the one who ordered the DMA’s creation. Also, with the goal of reuniting the Federation foremost in her mind, President Rillak may prove to be the sort of uncompromising politician who’d willingly unleash destruction upon the galaxy if she believed that doing so would serve a greater purpose.

Theory #7:
Dr Kovich is an agent (or the head) of Section 31.

Dr Kovich in The Examples.

I freely admit that this theory is barely clinging on right now, but I don’t believe it’s been completely disproven just yet! The questions of who Dr Kovich is and what exactly his role is within Starfleet and/or the Federation have no clear answer right now. He’s clearly someone with power and influence, as we’ve seen him working with Admiral Vance and seemingly being able to appoint anyone he chooses to be an instructor at Starfleet Academy. Yet he also seems to have some medical training, serving as a psychologist or counsellor – and it’s in this capacity that we saw him this week.

Because of the unclear nature of his role and the mysterious, stoic presentation from David Cronenberg, Dr Kovich is still an enigma. He’s also the kind of man who could potentially be an agent of Section 31. If it turns out that the Federation, President Rillak, and/or Section 31 are involved with the DMA, perhaps we’ll learn that Dr Kovich is as well. Or perhaps such a storyline will finally put this theory to bed once and for all!

Theory #8:
Captain Burnham and/or the Red Angel suits from Season 2 are connected to the DMA.

Captain Burnham in Anomaly.

Now that we know the DMA is artificial in nature, the question shifts to who built it and why. We’ve covered the idea of it being a weapon or an out-of-control experiment, as well as being a life-form in its own right. It could also be the responsibility of Section 31 or the Federation. But because this is Star Trek: Discovery, a show which likes to put Captain Burnham at the centre of its stories, perhaps there’s a connection to her that we’re missing.

The Red Angel time travel suits from Season 2 were phenomenally powerful machines, capable of generating time-wormholes large enough to transport an entire starship 930 years into the future. We already know that the DMA potentially contains a synthetic wormhole, so it wouldn’t be a huge leap to connect the two. We also don’t know for certain what became of Captain Burnham’s Red Angel suit after the Season 3 premiere. There’s also the faint possibility of a parallel universe Burnham or time travelling Burnham being responsible.

Theory #9:
Stamets and Ruon Tarka will create the DMA.

Stamets, Tarka, and Saru with the DMA model.

I included Stamets and Tarka on my list of suspects a couple of days ago, but they warrant a full entry on the theory list too! In short, we saw Stamets and Ruon Tarka creating a scale model of the DMA in The Examples, and according to Reno their experiment came very close to destroying the entire ship. They were able to perfectly recreate the device at the centre of the DMA, albeit on a smaller scale – so what’s to prevent them from building a full-scale replica?

This theory suggests that they will – somehow – and that doing so will set into motion a chain of events that leads to the creation of the DMA in a kind of time-loop storyline. The DMA’s wormhole-generating technology may give it the ability to travel backwards through time as well as across vast distances, so it seems technologically plausible at the very least.

Tarka and Stamets working on their model.

Ruon Tarka was shown as impatient in The Examples, and in his single-minded pursuit of the DMA he may be willing to take risks – perhaps risks which ultimately lead to the creation of the very anomaly he’s been investigating. How such a story would conclude is up in the air, but I don’t think we can rule it out as a possibility right now.

Personally, I find time-loop paradox storylines to be frustrating – and they can be very difficult to pull off successfully. There’s no beginning point to such a story: the DMA exists because the DMA was created because the DMA exists because the DMA was created… it’s an infinite loop. But we’ve seen Discovery tackle time travel stories like this before – and the pieces seem to be in play right now for this story.

So those theories are new or saw movement this week.

As always, I like to keep all of my theories in one place. So up next we’ll recap all of the other Season 4 theories that are currently in play. I find it helpful to keep the full list going like this – it makes it easier to keep track of all of the theories as they get confirmed or debunked.

Theory #10:
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
