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

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 the Qowat Milat helped save from cryo-sleep in the episode Choose To Live – could play a further role in Season 4.

Theory #10a:
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 #10b:
The Abronians’ homeworld was on the “other side” of the DMA.

Abronian stasis pods.

One clip in the second Season 4 trailer appeared to show Captain Burnham leading the USS Discovery inside the DMA. We don’t yet know what that means, nor to what extent words like “inside” the anomaly or “the other side” of the anomaly are even coherent concepts. But many times in past iterations of Star Trek we’ve seen things like wormholes and gateways to parallel universes. Perhaps the anomaly is something similar – and passing through it leads to a different dimension, parallel reality, or just a faraway region of space.

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 #10c:
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 #10d:
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 #11:
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: is there more to the DMA than meets the eye? If the anomaly is just an extreme example of space weather, flitting through Federation space destroying anything unfortunate enough to be in its way, then probably everyone on Kwejian is dead. But if the anomaly harbours some kind of gateway, wormhole, portal, time vortex, or any of the other Star Trek-y technobabble phenomena that we’ve seen across the franchise’s history, then it’s possible that at least some of the folks on Kwejian found themselves transported to whatever realm lies inside of the anomaly.

Theory #12:
Saru will be given the captaincy of the USS Voyager-J.

The USS Voyager-J.

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 #13:
A major character will be killed.

A Starfleet coffin seen in Deep Space Nine.

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

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

Spock’s funeral in The Wrath of Khan.

In short, I think there are plenty of reasons on the production side why killing off a major character could make sense in Season 4. Though we’ve already had one departure this season – that of Lieutenant Tilly – I still believe that Discovery could very easily go down this road, especially considering how dangerous the DMA currently is.

For a breakdown of which characters I thought might be in danger before the season premiered, check out my list of “death predictions” by clicking or tapping here.

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:
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 The Examples.

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 #16:
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 #17:
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 #18:
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 #19:
Captain Burnham and the crew will encounter the Klingons.

General Martok, a 24th 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 #20:
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 may now seek to put last season’s story to bed so it can wrangle with the DMA instead. 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 #21:
The Guardian of Forever will be back.

The Guardian of Forever first appeared in The Original 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. The DMA is something new and threatening, so it’s possible Captain Burnham might want to ask the Guardian for help or information.

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

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 by this point in the season that the show has been renewed. This 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.

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.

What adventure awaits the crew later this week?

Those are all of the theories that are currently in play as we await Stormy Weather – the sixth episode of Season 4. We’re accumulating quite a few theories, some of which completely contradict one another! So far, Discovery’s fourth season has been an interesting journey. We’ve has some slower character moments, some semi-episodic stories (that may yet come back into play), and some interesting developments in regards to the DMA. As we near the halfway point of the season, there are still many different ways that the story could go.

Stormy Weather looks like it’ll bring back Grudge – I hope the cute little ball of fluff will be okay! A dark matter anomaly is no place for a puss!

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

Star Trek: Discovery review – Season 4, Episode 5: The Examples

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.

The Examples was a stunningly good episode. When the season draws to a close, no matter how key storylines are ultimately paid off, we’ll look back and say this was one of the highlights. This week we got three stories rolled into one, all connected to the DMA in different ways, and we also got the introduction of a wonderfully complex new scientist character played by Shawn Doyle.

Before we go any further, I want to continue to call out the corporate nonsense from ViacomCBS that has prevented Star Trek fans from outside of Europe and North America from being able to watch Star Trek: Discovery. ViacomCBS seems to have no interest in Africa, Asia, or even countries and territories like Ireland or Puerto Rico, and the rollout of Paramount+, which continues at what we might generously call a snail’s pace, means nothing to millions of Trekkies all over the world. Discovery has become one of the most-pirated shows in recent weeks – something that’s entirely the fault of ViacomCBS and their decision to pull the show from Netflix.

The USS Discovery’s main viewscreen as the DMA approaches.

Let’s set that aside for now and talk about The Examples. We’ll begin with the smaller storyline present in the episode: that of Dr Culber and his emotional struggles. For me, these sequences with Dr Culber – and especially his conversations with Stamets – formed the episode’s real emotional heart. There was a moment toward the end between Captain Burnham and a prisoner named Felix that was also emotional, but we’ve known Dr Culber and followed his story for more than three seasons, so I think it’s natural to feel that this was the one that brought the most emotional weight.

I’m increasingly convinced that Discovery’s main characters each embody a different response to grief and trauma. In Tilly’s case, which we saw come to a head last week, she chose to leave the past behind and strike out on her own. In the case of Stamets we see the workaholic, someone willing to set aside much of his personal life and family commitments and throw himself into his work. The same kind of applies to Captain Burnham, though she also embodies the “protective partner” through her relationship with Book. Book, of course, has shown us the depths of depression and grief. And with Dr Culber we have someone who’s dedicated himself to helping others – even if that comes at his own expense.

Dr Culber and Stamets in their quarters.

The scenes between Stamets and Culber were a complete inversion of what I’d been expecting – and I loved every second of it. After Stamets missed Gray’s incorporation and wasn’t there for Adira in Choose To Live, I’d been expecting Dr Culber to be the one to call him out for overworking himself, telling him he missed something important with his family – and with his friend, as he wasn’t really there for Tilly before she left the ship. But instead we got the reverse of that: it was Stamets who had to tell Dr Culber that he’s been the one overworking himself for the sake of the crew.

This moment was absolutely perfect, and I felt it really drove home just how these two came to fall in love in the first place. Stamets and Culber have been Discovery’s emotional core since the show’s first season, but this was the first time we got this level of insight into what brought them together – and what has kept them together even through all the sci-fi adventures they’ve been on.

Stamets and Culber gave the episode heart and emotion.

Kovich – or should that be Doctor Kovich? – continues to confound me. Who is this mysterious man? We’ve seen him seemingly working for Starfleet Intelligence in some capacity, working alongside Admiral Vance at or near the top of the organisation, playing a leading role in Starfleet Academy – including being able to appoint teachers simply on his say-so – and now, in The Examples, he appeared to be acting as a counsellor, therapist, and even psychologist for Dr Culber. I wonder if Discovery plans to nail down Kovich at some point in the future – or if he’ll continue to be used in a variety of roles like this, allowing the lack of a clear explanation or background to provide him with an air of mystery and gravitas. It’s hard to deny that it’s working!

Kovich certainly laid some harsh truths on Dr Culber during their very short session together. And I liked that it came back to what happened to him in Season 2; Dr Culber went through an almost unimaginable experience, one that’s bound to leave emotional wounds. Past iterations of Star Trek were pretty bad at following up with characters who went through what should’ve been traumatic events, so it’s cathartic in a sense to see that the franchise is using its serialised format to right that old wrong.

Kovich offered Dr Culber counselling… of a sort.

Some of the goings-on at the prison felt a little rushed and a little forced. After discovering the existence of the prisoners and finding out that they weren’t scheduled to be rescued, Captain Burnham and the crew seem to have made no efforts to follow that up. Could they, for example, have located the prison guards who were said to have fled? Or sought out someone else capable of opening the prison? I know it’s a bit nit-picky, but going there in person feels like it should’ve been a last resort.

There was definitely an interesting element to the prison stand-off, though, once we got into the meat of this side of the story. I said last week that Captain Burnham has a “moral certainty” to her; she knows what is the right thing to do. This time she came upon two challenges to that morality – and I think in the way she responded to those challenges, we can see how much she’s grown as a character over the past three-plus seasons.

Captain Burnham faced a very difficult choice this week.

Captain Burnham wanted to rescue all of the prisoners. She wanted to do so not only for Book’s sake, as he’d been suffering ever since the destruction of his homeworld, but also because she truly believed in her heart that it was the objectively moral thing to do. The prisoners immediately challenged that, with several of them expressing the desire to be left to die rather than return to confinement. There was a bit of a cliché as we were told that one of the prisoners had “stolen food to feed his family,” but other than that this side of the story felt complex and nuanced.

We also got a glimpse at the kind of clashing of cultures that happens out here in the real world. The Akaali – a race that first appeared in Enterprise – have a very different culture to the Federation, perhaps influenced in part by the Emerald Chain. In this case, their ideas of justice, punishment, and imprisonment seem draconian by Federation standards – and Captain Burnham had to deal with that culture shock.

The Akaali magistrate.

Felix was the most complex of the prisoners, a man who’d killed someone decades earlier and had lived with that regret ever since. Guest star Michael Greyeyes put in a stellar performance as someone not merely resigned to their fate, but actively choosing to embrace it. Felix seemed to truly believe that his punishment or penance for his crime required his own death, and had he survived if the DMA had taken a different path, I believe he would have sought out the Akaali authorities and turned himself in all over again.

His choice was difficult for Book and Burnham, though, who had endeavoured to save all six prisoners. Book appeared to be ready to intervene, saving Felix’s life even if it went against his wishes, but Captain Burnham eventually understood that this was something she had to do. After all the talk earlier in the season about the Kobayashi Maru test and no-win scenarios, here we got to see Captain Burnham confronted with her own small-scale version of that very challenge. She rose to meet it in a way that she would have struggled to in earlier stories.

Leaving Felix behind was a kind of Kobayashi Maru moment for Captain Burnham.

There are many different ways we could read Felix’s story in The Examples. There’s definitely an allegory for imprisonment itself; that prison can have value as a rehabilitative institution. But we can also read Felix’s final choice through a more metaphorical and philosophical lens: it’s a tale about the value of freedom, and the freedom to choose one’s own path and ultimate fate. It’s a story about agency and the right to determine the outcome of one’s own life. Felix could have been “saved,” but doing so would have cost him his freedom in a different way.

This story took what could have been a fairly simple and uninspired plot about rescuing prisoners in a different and unexpected direction, providing some much-needed complexity to Captain Burnham’s side of the episode. It also gave both her and Book an emotional moment toward the end of the episode, with Book in particular believing the decision to leave Felix behind was wrong. And as the audience, we can see both sides of this argument and acknowledge that there’s no objectively right answer. On the one hand, if Felix had been saved he could have found other ways to have meaning in his life or to complete his penance and rehabilitate himself. Giving him that chance, even if it was against his will in that moment, could have paid dividends later. On the other hand, though, Felix was a grown adult of seemingly sound mind, and if this was the choice he freely made, knowing the consequences, does anyone have the right to interfere? It’s a complex story with no easy answer – and this could be a whole essay in itself drawing comparisons with things like the right-to-die movement, suicide, and many more.

Felix made his own decision.

Sonequa Martin-Green played Captain Burnham with real complexity this week, and her performance nailed Burnham’s real struggle with this decision. As recently as the season premiere, Burnham had said to President Rillak that she wasn’t ever willing to leave anyone behind or make this kind of choice; a variation on Captain Kirk’s famous “I don’t believe in no-win scenarios” stance. But something’s changed for Burnham – perhaps the existence of the DMA, or simply the realities of command. This evolution allows her to remain true to herself – she still wants to do the right thing. She just seems willing to consider different perspectives on what is “right,” including those that fall outside of her own interpretation.

So let’s take a look at the biggest revelation in The Examples: the DMA is an artificial creation. This is something I’d been theorising about in one form or another since we first learned of the existence of the anomaly in the first Season 4 teaser trailer earlier in the year, and I don’t think many fans or viewers will have been terribly shocked. A natural disaster angle could’ve worked well for the DMA, presenting Captain Burnham and the crew with a scientific challenge to untangle rather than a villainous adversary to defeat. But that ship has sailed – and really, this is the way I think we all expected Discovery to go with the DMA.

Tarka and Stamets created a scale model of the DMA.

Though this story was great overall, there was one part at the beginning that felt very rushed. After Stamets noticed the DMA disappearing and reappearing, Captain Burnham asked Zora (the ship’s AI) if the DMA could be a natural ocurrence. Zora replied that it couldn’t be, and based seemingly on these two lines alone, the rest of the plot was left to unfold. It just feels far too quick and easy to have gotten a one-line answer from Zora about the nature of the DMA, and I feel it would’ve been nicer to see at least some of the workings that led to that conclusion – perhaps Stamets could’ve said he’d come up with an artificial DMA as a new theory after weeks of work; same result, same short scene, but perhaps a better overall feeling that this wasn’t all based on one very brief analysis.

This second point is really more of a nitpick, but here we go anyway: how did everyone in the galaxy find out that the DMA isn’t a natural phenomenon? If Stamets is leading the charge on this investigation, and he only figured it out with the help of Zora… how did that news get out? Starfleet might’ve wanted to keep a lid on something so explosive, and I can absolutely see someone like President Rillak wanting to keep that news on a need-to-know basis to prevent panic and possible political consequences for the very tenuously-united Federation. Maybe we can excuse it by saying the DMA’s disappearance and reappearance led others to figure it out independently, but again this all happened very quickly at the beginning of the episode. It’s a nitpick, though.

Kaminar – and other worlds – already know that the DMA is artificial.

There were references to past iterations of Star Trek – as well as the video game Star Trek Online – on this side of The Examples. Admiral Vance listed the Metrons, who first appeared in The Original Series episode Arena, the Nacene, who constructed the Caretaker’s Array that pulled the USS Voyager into the Delta Quadrant, and the Iconian Empire, who were believed to be extinct during the events of The Next Generation but ultimately appeared in the aforementioned Star Trek Online.

However, at the end of the episode, Ruon Tarka explicitly ruled out all three of these races as being the culprit. So who is Species 10-C? And perhaps a bigger question is this: will the DMA connect back to a past iteration of Star Trek, or will the storyline follow a similar route to the Burn in Season 3 and ultimately turn out to be something altogether new? Part of me wants to say that we wouldn’t have had all of these teases if there wasn’t going to be some big connection and a big reveal that would be meaningful for us as the audience – the Borg, the super-synths from Picard, or something of that nature. But another big part of me is saying “remember the Burn!” and feels certain that we’re going to encounter someone entirely new.

Admiral Vance has a list of possible culprits… but Ruon Tarka dismissed them.

We’ll save the theorising for later, though, because this side of the episode had far more going on than just that! Shawn Doyle arrived as Ruon Tarka, and he played the arrogant scientist exceptionally well. Tarka is a strangely relatable character – I think a lot of us have known someone who’s so incredibly self-assured and who comes across as very rude and even selfish. Tarka, to my surprise I must admit, backed up his arrogance with genuine skill, and by the end of the episode even Stamets seemed to have warmed up to him!

There’s always going to be the temptation to have a character introduced in this fashion ultimately be proven wrong and get some kind of comeuppance, but what makes Tarka such an interesting and nuanced character is that he really did have the scientific skill and know-how to back up what he was saying; all the trash-talking with Stamets actually led somewhere. We can dislike Tarka for his abrasiveness and the way he was rude with Stamets and Saru, but at the end of the day I’m still left with a strong sense that, arrogant or not, he’s someone I want on my side – especially given the nature of the DMA. Pulling off that balance with a brand-new character isn’t going to be easy to get right, yet Discovery pulled it off thanks to a wonderful guest star.

Ruon Tarka made for a wonderfully complex character.

It was very sweet to get multiple mentions of Aurellio this week. Kenneth Mitchell played the character in Season 3, and even though he wasn’t able to appear in person on this occasion, the fact that Discovery went out of its way to reference the character more than once was incredibly sweet. It’s nice to know that Aurellio still exists in the 32nd Century, and that he’s teamed up with the Federation to help solve the mystery of the DMA. Again, I feel better knowing Aurellio is working on this problem too!

The idea that Stamets and Tarka came up with, to create essentially a scaled-down version of the DMA, was a good one, and it worked well on this side of the story. We got to see the two scientists truly working on the problem, tweaking their theories as they went along. This is the scientific method – having a crazy idea and testing it out! Other sci-fi shows would’ve skipped this step and just brought us the conclusion so we could get into more space battles and laser fights, but one thing I’ve always liked about Star Trek is seeing the characters slow down and take their time working on a problem. Neither Stamets nor Tarka could figure out the DMA instantly – and we’ve seen Stamets working on this problem across several episodes now. They seemed to be close to a breakthrough before the experiment had to be shut down – so perhaps a future episode will pick up that dangling story thread.

Stamets, Tarka, and Saru examine their model of the DMA.

Though she didn’t have many lines, it was great to welcome back Tig Notaro as Reno during this story. Her dry wit cut through what was a very heavy scientific story, and provided some moments of levity that were definitely appreciated. Due to the difficulties of travelling and filming during the pandemic, I already know we aren’t going to get as many Reno appearances as we might want – so it was great to see her on this occasion, and I will definitely savour those light-hearted moments that she brought.

Saru played a guiding role here, ultimately shutting the experiment down as it got too close to the danger zone. But he brought a sense of calmness to the proceedings, something necessary given the hot-headedness of Tarka and Stamets. Seeing him “roar” was definitely something a bit weird… but it was neat nevertheless! Saru was very much back in his element as the senior officer on this side of the story, taking command of the situation but deferring to the scientists as much as possible. Since he underwent the vahar’ai transformation in Season 2, we’ve seen this calmer presentation of Saru. I’ve said this before no doubt, especially during his tenure as captain in Season 3, but he makes for an excellent commander – someone kind of in the mould of Picard as a considerate, level-headed leader.

Saru and Tarka having a stand-off!

So that was The Examples. We’re one step closer to figuring out the DMA thanks to Tarka and Stamets’ dangerous experiment – and I hope to see further progress on that storyline soon! The suspense, not knowing who’s responsible for the DMA or what their goal might be is really pulling me in right now – I desperately want the answers to those huge questions!

Some scattered final thoughts: the USS Janeway was a neat callback to Voyager. We’ve had several references to both Enterprise and Voyager so far this season – could either of those be a tease or indication of the direction of the story? The DMA makes an interesting climate change analogy – something ever-present that our heroes all have to work together to overcome. The episode opened by reminding us that Tilly has gone, and Mary Wiseman is no longer credited in the opening credits – so I think her departure from the series is permanent. I had a horrible feeling that something was going to happen to Rhys as he took a leading role in the evacuation… but luckily he lives to fight another day!

I had a fantastic time with The Examples. It advanced the season’s main story in a huge and very significant way, introduced us to a new scientist character who was a ton of fun, and gave us some cathartic emotional moments with Captain Burnham, Book, Dr Culber, and Stamets. All in all, a truly outstanding episode. I’m tearing my hair out trying to figure out who Species 10-C might be – so stay tuned for my next batch of theories for more on that!

Star Trek: Discovery theories – week 4

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

All Is Possible definitely shook up Star Trek: Discovery! It’s an episode which, as things stand anyway, will have major ramifications for the rest of the show’s run thanks to the departure of Lieutenant Tilly. However, with the episode’s trio of stories largely staying away from the DMA (as the gravitational anomaly is now being called) there really aren’t a lot of new theories joining the list on this occasion. The teaser for The Examples has told us that we’re about to see a big return to that storyline, though, and I certainly don’t mind Discovery doing more of these episodic detours!

This week we had one theory that I’m calling semi-confirmed and one theory from way back in Season 3 that’s seen some significant advancement – but that I’m not yet willing to completely strike off the list! We’re also adding two production-side theories to the list for the first time.

Semi-confirmed theory:
Tilly left the USS Discovery.

Tilly is on her way to new adventures.

I’m calling this one semi-confirmed because I speculated about Tilly potentially leaving the ship – but I didn’t guess how soon it would happen or the exact manner of her departure! In the run-up to All Is Possible, my best guess was that whatever was happening with Tilly would rumble on for most of the rest of Season 4, with any potential departure not coming until closer to the end of the season. I certainly didn’t expect to see two “Tilly tries something new” storylines one after the other, and while her departure was very emotional and bittersweet, there was a slight sense that maybe it could’ve been scheduled a little better so we didn’t have both of Tilly’s big Season 4 episodes back-to-back.

I’d previously suggested that Tilly could change departments, resign from Starfleet, or that the character would be killed off by the writers. As it is we kind of got a combination of the first two: Tilly has left the USS Discovery’s science division to move to Federation HQ and teach at Starfleet Academy. She’ll presumably retain her commission as a Starfleet officer even though she isn’t working aboard a starship for the time being.

As I said in my review of All Is Possible, parts of Tilly’s story with the troublesome cadets almost felt like a backdoor pilot for a new series. With a Starfleet Academy show supposedly being worked on, we may not have seen the last of Tilly in Star Trek!

So that theory was semi-confirmed.

Up next we’ve got two production-side (as opposed to in-universe) theories.

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, as suggested, be 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’s first season in 2017, we’ve known by this point in the season that the show has been renewed. This 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 basically one-third of the way into Season 4 and to 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.

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 those are two theories on the production side of things.

Now we’ll get into the main theory list, beginning with any theories that are new or saw any significant movement in All Is Possible. Then, for the sake of keeping everything in one place, we’ll also recap those theories that didn’t change this week.

Theory #1:
Dr Culber is going to tell Stamets to slow down.

Dr Culber and Stamets in a promo image for The Examples.

Stamets has been almost entirely absent from the past couple of episodes – and in All Is Possible we heard Captain Burnham suggesting that Stamets “won’t slow down,” and is overworking himself as he tries to figure out what’s going on with the DMA. As a result of Stamets dedication to his work, he missed all of Gray’s incorporation in Choose To Live, and we haven’t seen him with Dr Culber, Adira, or Gray since the beginning of the season. He hasn’t even met Gray yet, not properly.

Stamets also didn’t have a chance to speak to Tilly before she left the ship, though he was briefly seen as she departed for Starfleet Academy. In the past, we’ve seen Dr Culber gently remind Stamets that he has other priorities aside from his work, and I’m beginning to wonder if the show is setting up the pair for something similar. I hope we don’t go back to the Season 2 conflict, because that genuinely did not work, but Stamets may need some kind of intervention from the man he loves, pointing out what he’s been missing while he’s been wrapped up in his work.

Theory #2:
President Rillak knows what the DMA is and may be responsible for its creation.

President Rillak in Kobayashi Maru.

All Is Possible continued a trend that we’ve seen across the opening episodes of Season 4, showing us that 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. By bringing Burnham and Saru along to the Ni’Var negotiations she hoped to find a solution to a diplomatic impasse she knew was coming – and she succeeded.

As I said in my review, 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 with Captain Burnham.

President Rillak might know more about the DMA than she’s currently letting on. If the Federation had created a weapon like this, or 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. President Rillak herself is a character with depth, not simply an “evil admiral” character trope. But it wouldn’t be the first time that Discovery has presented us with a fairly hard-line character in a position of authority who turns out to be concealing a dark secret.

We’ll consider in a moment a few other possible candidates for creating the DMA – if it turns out to be an artificial creation. But the Federation – and by extension, President Rillak – have to be possible contenders too. Season 3 of Discovery showed us the Federation at its weakest, but also arguably as an organisation that was still virtuous at its core. In contrast, we have Season 2’s depiction of Starfleet: reliant on the shady Section 31 and their AI. In short, it wouldn’t be unthinkable for Discovery to go back to that kind of presentation.

Theory #3:
Kovich is an agent (or the head) of Section 31.

Kovich in All Is Possible.

This is the theory that’s hanging on by a thread right now! Ever since we met the mysterious Kovich in Season 3, I’ve felt sure that there was something going on with him. His mannerisms, the way he seemed to know more than he was willing to share, and particularly the way he dealt with Empress Georgiou all contributed to that. I began to suspect that he could be an agent – or even the head – of Section 31, the shadowy off-the-books intelligence division that has done some very dubious things!

All Is Possible showed us a different presentation of Kovich. Referred to as Doctor Kovich for the first time, he seems to be playing a senior role in the running of Starfleet Academy. That doesn’t necessarily preclude him working for Section 31, but it is the most significant move away from this theory that we’ve seen so far.

Kovich in Season 3.

It may yet be revealed that Dr Kovich played a role in Tilly’s away mission going so badly wrong, but I suspect if that had been going to happen we’d have seen it in All Is Possible. David Cronenberg plays the character very stoically, which I think adds to that mysterious sense that has been present since Season 3. In All Is Possible, that contributed somewhat to the sense that he may have known what was going to happen.

If it turns out that the Federation and/or President Rillak are involved somehow with the DMA, maybe Dr Kovich is aware of what’s going on. If he’s involved with Section 31, it may turn out that the organisation has important information about the DMA or even knows how to prevent it from doing any more harm.

So those theories were new or saw movement this week.

Now, as always, we’ll recap all of my other Discovery Season 4 theories. I find it helps to keep the full list in one place; it makes it easier to strike off theories when they’ve been debunked or confirmed, and it means nothing gets forgotten about or left behind! At least, that’s the plan!

Theory #4:
The Guardian of Forever will be back.

The Guardian of Forever first appeared in The Original 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. The DMA is something new and threatening, so it’s possible Captain Burnham might want to ask the Guardian for help or information.

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

Theory #5:
Some areas of the galaxy – such as the Delta Quadrant – avoided the worst effects of the Burn.

The USS Voyager traversed the Delta Quadrant.

Season 4 touched briefly on the Burn with Su’Kal and Saru in Kobayashi Maru, and may now seek to put last season’s story to bed so it can wrangle with the DMA instead. 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 #6:
Captain Burnham and the crew will encounter the Klingons.

General Martok, a 24th 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 #7:
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 #8:
The story will connect with the Short Treks episode Calypso.

Craft, the protagonist of Calypso.

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

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

Theory #9:
The ban on time travel will be explained in more detail.

The USS Enterprise was able to travel back in time to the 20th Century from the 23rd without too much difficulty.

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 #10:
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 #11:
Burnham won’t stay in the captain’s chair.

Captain Burnham in All Is Possible.

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 Anomaly.

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 #12:
There will be a character crossover from a past iteration of Star Trek.

Spock has appeared in several different Star Trek productions.

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!

Riker has appeared in more Star Trek spin-offs than any other character.

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 #13:
A major character will be killed.

A Starfleet coffin seen in Deep Space Nine.

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

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

Spock’s funeral in The Wrath of Khan.

In short, I think there are plenty of reasons on the production side why killing off a major character could make sense in Season 4. Though we’ve already had one departure this season – that of Lieutenant Tilly – I still believe that Discovery could very easily go down this road, especially considering how dangerous the DMA currently is.

Theory #14:
The DMA is a superweapon.

One view of the DMA.

We touched on this theory above when we considered the Federation’s possible complicity in the creation of the DMA, but there are many other ways such a story could pan out. The DMA’s unpredictable nature, as noted by Tilly and Saru at the end of Anomaly, could imply that there’s an intelligence at work dictating its moves. This could be the DMA itself if it’s sentient (or contains a sentient life-form) but it could also be the case that it’s being controlled or manipulated by something or someone externally.

If the anomaly turns out not to be a natural phenomenon, and is indeed deliberately targetting the Federation, who might the possible culprits be? And what would be the purpose behind attacking the Federation in this manner? If it’s the precursor to an invasion, perhaps later in the season we’ll see whoever is responsible making their next move.

Theory #14a:
The Borg are responsible.

The Borg Queen.

We don’t know whether the Borg Collective still exists in the 32nd Century; it hasn’t even been mentioned since the USS Discovery’s arrival. However, few other established factions seem capable of creating a weapon on the scale of the DMA. This wouldn’t be in line with the Borg’s usual modus operandi, as they prefer to assimilate rather than attack from afar. But a lot may have changed in the centuries since we last encountered them, meaning this could be the opening salvo of a Borg attack… or the last gasp of a dying Collective.

Theory #14b:
The super-synths from Picard Season 1 are responsible.

Some very menacing-looking synthetic tentacles.

We still don’t know very much about the super-synths that Soji and Sutra attempted to contact in the Season 1 finale of Star Trek: Picard. Other than claiming to offer support and help to synthetic life, what are their goals and motivations? Was their offer even genuine, or was it a trap? The mechanical tentacles glimpsed in Picard Season 1 looked terrifying! Moreover, we know that the super-synths have the technology to move stars – something only possible with an advanced understanding of gravity. Creating a stable 8-star octonary system is an incredible technological and gravitational feat, so they have precedent of a sort when it comes to working with gravity. Finally, Discovery Season 4 has already made connections with Picard Season 1: the Qowat Milat and the synth transfer process used for Gray.

Theory #14c:
The Kelvan Empire is responsible.

Rojan, a representative of the Kelvan Empire.

This one might seem to come completely out of the blue! In The Original Series, Captain Kirk met representatives of the Kelvan Empire, a faction originally from the Andromeda galaxy. Seeking a new home, a Kelvan scouting party had reached the Milky Way and were looking for worlds to conquer. Kirk would ultimately dispatch an unmanned starship offering to help the Kelvan Empire find new worlds to settle – but what if his offer was rejected? Given the vast distances and travel time involved, the timelines kind of line up for the Kelvan Empire to return to the Milky Way.

Theory #14d:
The Sphere-Builders from Enterprise are responsible.

A Sphere-Builder seen in Enterprise.

A defeated faction in one of the Temporal Wars, the Sphere-Builders initially hoped to convert a large swathe of the Alpha Quadrant to match their native extradimensional realm, and constructed a number of large space stations known as Spheres to facilitate this transformation. Crewman Daniels would tell Captain Archer that the Sphere-Builders were defeated in the 26th Century, but could they have since rebuilt? The DMA isn’t necessarily the same as what they were trying to do with the Spheres, but they’re one of the few factions in Star Trek that might be capable of creating a weapon on this scale.

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

The USS Voyager-J.

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:
The DMA is (or contains) a sentient life-form.

Another view of the DMA.

“It was only trying to communicate!” has become a Star Trek cliché, often used to describe how the seemingly-aggressive actions of an alien life-form are actually something innocuous. Maybe the same is true of the DMA: at its core is a life form, perhaps one not dissimilar to the Sphere seen in Season 2, and it’s on its own mission of exploration.

V’Ger from The Motion Picture is an interesting comparison. Like the DMA, V’Ger was massive in size, capable of destroying space stations, fleets of ships, and even threatening to destroy entire planets. When Admiral Kirk and the crew of the Enterprise were able to figure out V’Ger, however, they found a life-form at its core, one which was just as curious to learn and grow as they were.

Theory #17:
Book will find Kyheem and Leto inside the DMA.

Leto as seen in Book’s memory.

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: is there more to the DMA than meets the eye? If the anomaly is just an extreme example of space weather, flitting through Federation space destroying anything unfortunate enough to be in its way, then probably everyone on Kwejian is dead. But if the anomaly harbours some kind of gateway, wormhole, portal, time vortex, or any of the other Star Trek-y technobabble phenomena that we’ve seen across the franchise’s history, then it’s possible that at least some of the folks on Kwejian found themselves transported to whatever realm lies inside of the anomaly.

Theory #18:
Captain Burnham and/or the Red Angel time travel suits from Season 2 are connected to the DMA.

We don’t really know what happened to the Red Angel suit after this moment.

I’m not sure that this one is particularly likely, but as I said last year about a possible Burnham connection to the Burn, not only does Discovery kind of have a precedent for telling this kind of story, but there would also be something very dramatic about this revelation. In this case, Burnham would be indirectly and unknowingly responsible for creating something devastatingly damaging. How would she react to that, and how would Book react given what happened to Kwejian?

Perhaps the Red Angel suit, which Burnham sent back in time in the Season 3 premiere, malfunctioned somehow, and its powerful wormhole-creating technology gave rise to the DMA. If the Red Angel suit completed its journey back to the 23rd Century, the anomaly may have had centuries to grow and expand unchecked. If time travel is involved, perhaps a future Captain Burnham or a parallel universe Captain Burnham could be responsible for the anomaly’s creation – either intentionally or not.

Theory #19:
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 #19a:
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 #19b:
The Abronians’ homeworld was on the “other side” of the DMA.

The USS Discovery approaches the DMA.

One clip in the second Season 4 trailer appeared to show Captain Burnham leading the USS Discovery inside the DMA. We don’t yet know what that means, nor to what extent words like “inside” the anomaly or “the other side” of the anomaly are even coherent concepts. But many times in past iterations of Star Trek we’ve seen things like wormholes and gateways to parallel universes. Perhaps the anomaly is something similar – and passing through it leads to a different dimension, parallel reality, or just a faraway region of space.

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 #19c:
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 #19d:
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.

So that’s it!

The USS Discovery.

At present, those are all of the theories I currently have in play. Some are more likely than others, some are perhaps plausible but may not come into play in Season 4, and maybe some are just plain silly! But I have a lot of fun thinking them up and writing these lists, and that’s really what this is all about!

After two episodes in a row in which we got minimal advancement of the season’s main storyline, The Examples seems to be teasing us with a return to the DMA in a significant way. I can hardly wait to see what lies in store for Captain Burnham and the crew!

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 – weeks 1-2

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.

Now that all of the international broadcasting nonsense is out of the way, let’s get back into my weekly Discovery theory updates! We only missed one week, and there’s still a ton of speculating to be done about the story of Season 4, the gravitational anomaly, and what might become of some of our favourite characters.

If you’re new to my weekly theory updates for Discovery Season 4, here’s how the format works: after every episode I go back to my theory list. I cross off theories that have been debunked, celebrate any that appear to have been confirmed, update any that have seen progression, and add any new theories that the most recent episode has spawned. There will be some theories that, for whatever reason, the most recent episode didn’t advance in any way, so those will simply be restated to keep the list up-to-date and in one place!

I wrote up all of my pre-season theories into one list a couple of weeks ago, so this time we’ve already got two confirmations to take a look at before we jump into the main list.

Confirmed theory #1: The Spore Drive will be rolled out to more ships.

Book in Discovery’s Spore Drive cube.

Finally! After the revelation in the Season 3 finale that Book – and potentially anyone else with similar empathic abilities – could control the Spore Drive, the last hurdle in the way of it being rolled out to other Starfleet ships had been surmounted. It finally feels like Discovery is on the cusp of finding another use for what had been one of the most controversial technologies introduced in the series.

In Kobayashi Maru this was almost treated as a throwaway line, so I wouldn’t blame you if you missed it, but President Rillak confirmed that a “next-generation” Spore Drive is being developed by Starfleet as part of the Federation’s plans to rebuild and expand. It wasn’t stated on screen, but I wonder if the USS Voyager-J might be fitted with a Spore Drive as part of its retrofit; the vessel was in spacedock, after all.

The USS Discovery makes a Spore Drive jump.

I’d been hoping that the series would go down this road for a while. Moving forward in time to the 32nd Century means there are no “canon purist” arguments in favour of abandoning the Spore Drive, keeping it a secret, or ensuring that only the USS Discovery could use it. And the events of the Season 3 finale seemed deliberately designed to create an easy way to expand the Spore Drive to more ships – perhaps even paving the way for future Star Trek productions in this era.

We don’t yet know what the implications will be of Kwejian’s destruction on Starfleet’s plans. It was implied in the Season 3 finale that anyone with empathic abilities could use the Spore Drive, not only Kwejian natives, so the loss of Kwejian and most of its population shouldn’t mean that the Spore Drive expansion has to be abandoned. It might be possible for Betazoids, Deltans, or even Vulcans to train to become Spore Drive navigators.

Confirmed theory #2: A new character joined the main cast.

A new name has been spotted in the opening credits!

Following the departures of Nhan and Georgiou, it felt like there was definitely scope to either promote a recurring character to the main cast or create at least one new one! We’ve met President Rillak, who seems like she’ll become a recurring character, but the one who’s been promoted to join the main cast is Blu del Barrio’s character of Adira.

Adira makes a great addition to Discovery’s main cast of characters, occupying a similar role to Tilly in Season 1 in particular. As Tilly has undergone significant character growth across the show’s first three seasons, there was scope to bring someone brand-new aboard the ship, and having that person be someone young and eager is a positive thing. Adira is not only involved in their own storyline with Gray and Dr Culber, but also as a scientist can work with Stamets, Tilly, Saru, and Captain Burnham. I think Adira has the potential to be a versatile character in whatever stories lie ahead.

My original version of this theory centred around the question of Captain Burnham’s first officer. Now that we know that role has gone to Saru, it seems as though the main and recurring characters for this season are set.

So those theories were confirmed. Now we’ll take a look at some new theories and a few updated theories.

Theory #1: President Rillak knows what the anomaly is… and may be responsible for its creation.

President Rillak in Kobayashi Maru.

This ties into a broader point that we’ll be considering from several angles: the possibility that the gravitational anomaly is not a natural phenomenon. If the anomaly is artificial in nature, the question of who is responsible for its creation crops up. It could be a weapon deployed by another faction, of course, but it could also be a Federation creation – perhaps a weapon designed to defend against the Borg, a rogue experiment to try and prevent a second Burn, or something else entirely.

If that’s the case, President Rillak almost certainly knows more about the anomaly than she’s willing to say right now. Perhaps she’s hoping that it won’t be what she fears it is, or perhaps she’s trying to cover her own back – Captain Burnham did go out of her way to describe her as a “politician,” after all.

Does President Rillak know more about the anomaly than she’s saying?

President Rillak is a character with depth, not simply an “evil admiral” character trope. But it wouldn’t be the first time that Discovery has presented us with a fairly hard-line character in a position of authority who turns out to be concealing a dark secret.

As the head of the Federation, President Rillak is committed to doing whatever it takes to preserve the organisation. The anomaly may have been part of those plans… somehow. If she isn’t responsible for its creation directly, she may still know what it is if a past Federation President signed off on its creation. She may be covering up that secret on behalf of the Federation.

Theory #2: Captain Burnham and/or the Red Angel time travel suits from Season 2 are connected to the anomaly.

Captain Burnham.

Though we did see some moves away from Discovery’s laser-focus on Michael Burnham in Season 3, the show has put her front-and-centre in all of its main storylines so far. Season 2’s Red Angel storyline was connected to Burnham in a major way, and I wonder if Burnham might similarly have some kind of connection to the anomaly that she’s currently unaware of.

Perhaps the Red Angel suit, which Burnham sent back in time in the Season 3 premiere, malfunctioned somehow, and its powerful wormhole-creating technology gave rise to the gravitational anomaly. If the Red Angel suit completed its journey back to the 23rd Century, the anomaly may have had centuries to grow and expand unchecked.

This was the last we saw of the Red Angel suit back at the beginning of Season 3.

I’m not sure that this one is particularly likely, but as I said last year about a possible Burnham connection to the Burn, not only does Discovery kind of have a precedent for telling this kind of story, but there would also be something very dramatic about this revelation. In this case, Burnham would be indirectly and unknowingly responsible for creating something devastatingly damaging. How would she react to that, and how would Book react given what’s just happened to Kwejian?

If time travel is involved, perhaps a future Captain Burnham or a parallel universe Captain Burnham could be responsible for the anomaly’s creation – either intentionally or not.

Theory #3: Gray’s transfer to a new body won’t be simple.

A holographic representation of Gray’s synthetic body.

I adored the scene with Gray, Adira, and Dr Culber in Anomaly. As someone who’s struggled to come to terms with my own gender identity and my gender expression, it was so deeply relatable to see Gray “customising” his new body. But also included in that scene was a line from Dr Culber about how the “Soong method” used to transfer consciousness into a synthetic form has a very low success rate.

I suspect that line was included as a kind of pre-emptive plot hole plug that will have nothing to do with Gray! If the Soong method was said to work every time, then it would be very difficult to kill off any Star Trek characters from the 25th Century onwards, because fans would rightly ask “why didn’t they transfer to a synth body?” So I suspect that’s why the line was included.

Admiral Picard had his consciousness transferred to a synthetic body in the finale of Picard Season 1.

However, it felt a little ominous for poor Gray. It was great to see that Adira, Dr Culber, and others had been working hard to help Gray become seen again after the events of Season 3, and I have no doubt that somehow we’ll see Gray in a physical body before the season is over. But we’re only two episodes in at time of writing – will it really happen so quickly, and so seemingly simply?

I’m not convinced of that yet! There are many things that could go wrong, delay the transfer, or prevent it entirely. And there are an unlimited number of technobabble explanations for finding a new way to give Gray a body! So let’s see what happens – but I wonder if this storyline might have a few twists and turns along the way.

Theory #4: Book will find Kyheem and Leto inside the gravitational anomaly.

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. We don’t know what the gravitational anomaly 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: is there more to the gravitational anomaly than meets the eye? If the anomaly is just an extreme example of space weather, flitting through Federation space destroying anything unfortunate enough to be in its way, then probably everyone on Kwejian is dead. But if the anomaly harbours some kind of gateway, wormhole, portal, time vortex, or any of the other Star Trek-y technobabble phenomena that we’ve seen across the franchise’s history, then it’s possible that at least some of the folks on Kwejian found themselves transported to whatever realm lies inside of the anomaly.

Theory #5: The anomaly is a sentient life-form.

Could the anomaly be similar to V’Ger?

“It was only trying to communicate!” has become a Star Trek cliché, often used to describe how the seemingly-aggressive actions of an alien life-form are actually something innocuous. Perhaps the same is true of the gravitational anomaly: at its core is a life form, perhaps one not dissimilar to the Sphere seen in Season 2, and it’s on its own mission of exploration.

V’Ger from The Motion Picture is an interesting comparison. Like the gravitational anomaly, V’Ger was massive in size, capable of destroying space stations, fleets of ships, and even threatening to destroy entire planets. When Admiral Kirk and the crew of the Enterprise were able to figure out V’Ger, however, they found a life-form at its core, one which was just as curious to learn and grow as they were.

Theory #6: Saru will be given the captaincy of the USS Voyager-J.

The USS Voyager-J.

Saru’s future was briefly discussed before he offered to serve as Captain Burnham’s first officer. 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?

At time of writing, a fifth season of Discovery hasn’t been officially confirmed. But if the show is to run for another season – or more – the question of Saru’s role comes up. It would be possible to work out a way to keep him on board as first officer for longer than one season, and in many ways I think that’s something fans would want to see. But at the same time, from an in-universe point of view, it kind of makes sense for Starfleet to use its experienced captains where possible.

Captain Saru.

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.

If Saru did depart Discovery in a future episode or season, could that perhaps set the stage for Star Trek: Saru… or perhaps Star Trek: Voyager-J? That’s a very interesting possibility! One element of Season 3 that I felt didn’t really get as much attention as it might’ve was that Saru was the Star Trek franchise’s first non-human captain (in a leading role). There’s perhaps scope to follow him on another adventure sometime in the future.

Theory #7: The gravitational anomaly is a superweapon.

The USS Discovery approaching the anomaly in the second Season 4 trailer.

We touched on this theory above when we considered the Federation’s possible complicity in the creation of the gravitational anomaly, but there are many other ways such a story could pan out. The anomaly’s unpredictable nature, as noted by Tilly and Saru at the end of Anomaly, could imply that there’s an intelligence at work, perhaps dictating the anomaly’s moves. This could be the anomaly itself as suggested above, but it could also be the case that the anomaly is being controlled or manipulated by something or someone externally.

If the anomaly turns out not to be a natural phenomenon, and is indeed deliberately targetting the Federation, who might the possible culprits be? And what would be the purpose behind attacking the Federation in this manner? If it’s the precursor to an invasion, perhaps later in the season we’ll see whoever is responsible making their next move.

Theory #7a: The Borg are responsible.

We don’t know whether the Borg Collective still exists in the 32nd Century; it hasn’t even been mentioned since the USS Discovery’s arrival. However, out of all of the factions in Star Trek, few seem capable of creating a weapon on the scale of the gravitational anomaly. This wouldn’t be in line with the Borg’s usual modus operandi, as they prefer to assimilate rather than attack from afar. But a lot may have changed in the centuries since we last encountered them, meaning this could be the opening salvo of a Borg attack… or the last gasp of a dying Collective.

Theory #7b: The super-synths from Picard Season 1 are responsible.

This is all we really saw of the super-synths.

We still don’t know very much about the super-synths that Soji and Sutra attempted to contact in the Season 1 finale of Star Trek: Picard. Other than claiming to offer support and help to synthetic life, what are their goals and motivations? Was their offer even genuine, or was it a trap? The mechanical tentacles glimpsed in Picard Season 1 looked terrifying! Moreover, we know that the super-synths have the technology to move stars – something only possible with an advanced understanding of gravity. Creating a stable 8-star octonary system is an incredible technological and gravitational feat, so they have precedent of a sort when it comes to working with gravity.

Theory #7c: The Kelvan Empire is responsible.

Rojan, a representative of the Kelvan Empire.

This one might seem to come completely out of the blue! In The Original Series, Captain Kirk met representatives of the Kelvan Empire, a faction originally from the Andromeda galaxy. Seeking a new home, a Kelvan scouting party had reached the Milky Way and were looking for worlds to conquer. Kirk would ultimately dispatch an unmanned starship offering to help the Kelvan Empire find new worlds to settle – but what if his offer was rejected? Given the vast distances involved, the timelines kind of line up for the Kelvan Empire to return to the Milky Way.

Theory #7d: The Sphere-Builders from Enterprise are responsible.

A Sphere-Builder seen in Enterprise.

A defeated faction in one of the Temporal Wars, the Sphere-Builders initially hoped to convert a large swathe of the Alpha Quadrant to match their native extradimensional realm, and constructed a number of large space stations known as Spheres to facilitate this transformation. Crewman Daniels would tell Captain Archer that the Sphere-Builders were defeated in the 26th Century, but could they have since rebuilt? The gravitational anomaly isn’t necessarily the same as what they were trying to do with the Spheres, but they’re one of the few factions in Star Trek that might be capable of creating a weapon on this scale.

So those theories were new or saw some advancement in the first two episodes of the season.

To keep these theory posts as uncomplicated as possible, I like to keep all of my theories in one place. So below you’ll find all of my other Season 4 theories. These weren’t debunked or confirmed in the first two episodes, and indeed saw no real movement at all. They remain in play, though.

Theory #8: A major character will be killed.

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

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

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

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

There are also a couple of characters who feel in danger for different reasons. For a full breakdown of which characters I think might be on the proverbial chopping block, check out my list of “death predictions” by clicking or tapping here.

Theory #9: There will be a character crossover from a past iteration of Star Trek.

Voyager’s Doctor is a contender!

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

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

Could Sutra still be alive in the 32nd Century?

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

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

Theory #10: Burnham may not remain 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.

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 #11: Kovich works for Section 31.

Kovich in Season 3.

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

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

Theory #12: The ban on time travel will be explained further.

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

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

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

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

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

Sticking with the time travel ban, another theory I had last season was that the Federation – and Section 31 in particular – might have deliberately flouted the ban and failed to abide by the rules. Someone as straight-laced and committed to Starfleet ideals as Admiral Vance is highly unlikely to have sanctioned such a move, but someone like the shadowy Kovich (who we talked about a moment ago) might have. President Rillak could also be involved.

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

Theory #14: The story will connect with the Short Treks episode Calypso.

The USS Discovery seen in Calypso.

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

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

Theory #15: The crew will have to defend the Verubin Nebula.

The dilithium planet at the centre of the Verubin Nebula.

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

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

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

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

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

Theory #16: Captain Burnham and the crew will encounter the Klingons.

The Klingons have been part of Discovery since the beginning.

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

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

Theory #17: Some areas of the galaxy – such as the Delta Quadrant – avoided the worst effects of the Burn.

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

It’s quite possible that Season 4 won’t revisit the Burn narrative in any detail. But one thing I’d be curious to see is the true extent of the disaster – did it reach all four quadrants of the galaxy equally, or did its effects fade out after a certain point? Michael Burnham discovered that the Burn had a point of origin, and that it radiated out from that point like ripples o
