Star Trek: Discovery review – Season 4, Episode 11: Rosetta

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

Last week’s episode, The Galactic Barrier, was absolutely fantastic – one of the highlights of the season for certain! Unfortunately Rosetta didn’t reach that high bar, and was an episode that felt like it was dragging its feet. While there were some emotional character moments, even those weren’t as strong as they might’ve been and couldn’t salvage an episode in which both halves of the story felt contrived, and where a major new element that had been introduced to the story last week constantly got in the way. Rosetta plodded along, constantly tripping over one big, unnecessary narrative cliché.

I like the idea of Discovery stepping away from total serialisation to go on away missions to planets like the one featured in Rosetta. As we saw just last week – and on a couple of occasions earlier in the season – those semi-standalone stories can work exceptionally well, blending together Discovery’s modern serialised approach to storytelling with at least some components of Star Trek’s episodic past. But this week, for much of the time all I could feel was a sense that the mission to Unknown Species 10-C’s ex-homeworld was a complete waste of time – not only for the characters, who don’t have so much as a second to waste, but more importantly for us as the audience.

The away team.

The worst part of last week’s episode was the insertion of the horribly overused trope of Earth being in danger. I tried to put that to the back of my mind as Rosetta got started, hoping that the time constraint it had imposed would lead to some kind of interesting or exciting storyline as Season 4 reaches its conclusion. But this cliché absolutely ruined Rosetta – turning a story that might’ve had the kernel of a good idea at its core into one that felt like a complete and utter waste of everybody’s time. With time being a very limited resource for Captain Burnham, that just isn’t something that should have been allowed to happen!

If the “Earth is about to be destroyed” cliché wasn’t part of the season’s story, this feeling would have been far less prominent throughout Rosetta, and I could have almost certainly forgiven another detour on the way to Unknown Species 10-C’s hyperfield. With less of a time constraint, such a mission would arguably be worth doing, and while there could still be naysayers and dissenters among the crew and assembled delegates, I would have been firmly in the camp that says “let’s see if we can find any interesting or useful information about this completely unknown faction.” But because Discovery’s writers wanted to crank up the tension and drama to eleven out of ten, what should have been a decent episode with some interesting story elements didn’t work. Instead of the tension rumbling in the background, spurring me on to make the story feel exciting, I could barely prevent myself from shouting at the series to just get on with it – to go to the hyperfield right now! Tension became frustration.

Captain Burnham chose to lead an away mission to a planet instead of racing to the hyperfield.

Not for the first time, narrative contrivances in Discovery have conspired to make Captain Burnham seem like she’s in the wrong. While not exactly being a complete and utter moron, she came across in the episode’s opening act as misguided in the extreme – wasting time on a mission that could have easily yielded nothing of consequence. As happened in episodes like The Vulcan Hello and The Red Angel, it fell to another character to be the voice of reason against Captain Burnham – in this case, Earth’s representative, General Ndoye.

Ndoye made the very simple point that there isn’t time to waste visiting a random planet, and that attempting to make contact first would be the best move. If Unknown Species 10-C didn’t respond to attempts at communication, visiting the planet could be Plan B – but there’s no way it should’ve been Plan A. Rosetta attempts to rely on the away team’s discovery of pheromone-like hydrocarbon dust to say “aha! Captain Burnham was right all along!” but in my view, all that the end of the episode proved was that she got very lucky. Her judgement, four seasons in, is still questionable at times – and on this occasion, with the stakes so very high, I can’t shake the feeling that she made the wrong call.

General Ndoye became the voice of reason… briefly.

The hydrocarbon pheromones will almost certainly play a role in the next couple of episodes – I mean, they have to, right? Otherwise Rosetta will have proven to be a complete waste of time. But even assuming that’s the case, Captain Burnham took a massive risk by diverting to the planet with hours to spare, and it just feels like – not for the first time this season – there was a very easy “middle ground” approach that neither she nor anyone else seems to have considered.

The USS Discovery is equipped with a contingent of shuttles, so sending one with a small away team to the planet while the rest of the crew takes the ship and visits the hyperfield – instead of sitting in orbit of the planet doing fuck all – would have been the hallowed “middle ground” option that the show’s writers seem to have just ignored. Because Captain Burnham has to be the main focus of practically every episode and every major plotline, other characters in the show are relegated to sitting on their hands and waiting for her latest stroke of brilliance. In this case, everyone with the exception of Detmer, Saru, and Dr Culber were just shoved off-screen, seemingly doing nothing except waiting for Captain Burnham to get back. Adira and Reno even found time to get coffee.

This picture is Rosetta in microcosm: Captain Burnham goes off on an away mission while everyone else stands around doing nothing.

That makes Discovery Season 4 feel like a pretty basic story – one designed for small children who don’t have the attention to focus on more than one major narrative at once. Because Captain Burnham wanted to visit the planet, everyone has to visit the planet. God forbid any other character is granted any agency over the plot or given the volition to do anything independently – they’re not real people, you know, just narrative devices.

And yes, it’s Star Trek. It’s fiction. It’s “just a story” – but god do I hate that tired excuse every time it’s trotted out in defence of contrived, underwhelming, or just plain indefensible narratives. If we’re expected to suspend our disbelief and get lost in the world of Star Trek, even just for an hour, the way characters behave has to make basic sense. The characters themselves have to feel like real people – flesh-and-blood beings with emotions, feelings, and brains, not just plot devices who can be used one moment then placed into hibernation the next. And this week, Rosetta basically sidelined the entire crew, forcing them to sit on their hands and do nothing while Captain Burnham took charge of a pretty barebones side-story that I’m not even sure accomplished all that much.

The away team with a cache of magic dust.

I said earlier that the pheromone hydrocarbons will have to feature in the story in some way later on – and I certainly hope that they will! But as of the end of Rosetta, the mission to Unknown Species 10-C’s ex-planet doesn’t feel as though it achieved very much. Captain Burnham didn’t find anything substantial – and the dust, while narratively interesting, was visually unimpressive to say the least. If there had been something more visually unique or interesting about what the away team recovered – like one of the bones that were briefly seen, a computer core, a stone tablet, or literally anything we as the audience could see, maybe that feeling wouldn’t be so prevalent. But because even the away mission’s big accomplishment was difficult to really perceive, the entire story feels like it’s on far shakier ground than it already was.

If the pheromone hydrocarbons are incorporated into the story of the next couple of episodes in a major way, maybe we’ll revisit Rosetta and consider it a little more favourably in hindsight. There are definitely interesting possibilities with this new narrative element that could be explored or that could be paid off in a big way. But if Discovery doesn’t do something big with the pheromone hydrocarbons before the end of the season, the episode will feel like even more of a waste than it already does.

Will the pheromone dust play a significant enough role in the story to make Rosetta feel like a worthwhile detour?

In past iterations of Star Trek – including in previous episodes and seasons of Discovery – the universal translator has been shown to work pretty well. There are some exceptions – such as the Tamarians – but even then a way across the language barrier was eventually found. With the 900-year time jump to the 32nd Century, it stands to reason that the universal translator has only gotten better as Starfleet has encountered more and more races. Even if we accept the premise that communication has never been successfully made with a species that uses pheromones or chemicals to communicate, doesn’t it seem like it would be worth trying to use the universal translator, especially given the time constraints? With the level of technology that Unknown Species 10-C has been shown to have, they might have some kind of translator or communicator of their own, too.

I know a lot of this must sound like nitpicking, but it all stems from the fact that the show’s writers chose to inject forced drama by using an “Earth is in danger and there’s just hours to save it!” cliché that wasn’t necessary to make this story interesting or exciting. The stakes were high enough, the danger was real enough, and by trying to turn the drama up to eleven, Rosetta tripped over. There was a potentially interesting story about learning more about a very new and different form of life… but it’s one that this cliché has spoiled. Take away the time constraint and many of the narrative complaints on this side of the story would have fallen away.

A holographic depiction of the hyperfield.

Rosetta wasn’t saved by its B-plot, either, with Tarka and Book undertaking an equally nonsensical away mission that also seemed to be based on a very shaky premise. With Captain Burnham’s decision to take an away mission to the planet, my criticism stems from the fact that The Galactic Barrier had introduced the cliché of Earth being threatened meaning that there wasn’t time for a detour. But Book and Tarka’s away mission to the USS Discovery was done because they… wanted to stick Book’s ship to Discovery’s hull? Couldn’t they just remain under cloak and tail the ship? It feels pretty weak, even by the standards of Star Trek technobabble.

We also didn’t get to see any of Book and Tarka’s journey navigating the Galactic Barrier, which is something I was genuinely interested in. A powerful ship like the USS Discovery barely made it through, so how would Book’s glorified runabout survive? We basically got no payoff to Book and Tarka’s side-mission last week of collecting programmable antimatter at the abandoned prison camp. Presumably they were able to successfully apply it and transit the Galactic Barrier – but the episode literally didn’t even pay lip service to that, with their story starting up with Book’s ship already parked a few yards away from the USS Discovery.

Couldn’t Book and Tarka just continue to tail Discovery? Also, how did they make it through the Galactic Barrier?

Given how difficult navigating the Galactic Barrier proved to be for the USS Discovery, it’s a shame that we didn’t get to see Book and Tarka having to tackle that task. Maybe it could’ve been included at the end of last week’s episode – even if it was just a short sequence, Discovery should really have done something to pay off their mission to the prison camp.

It also seems like Book has decided that he and Tarka are fugitives without even trying to make contact and explain what happened. The end of Rubicon suggested that there might be a pathway to reconciliation for him and Michael, but he has done nothing to attempt to pursue that – except for creepily spying on her in what has to be one of the most uncomfortable moments in the entire episode. Book signalled his willingness to stand down and give peace a chance; it was only Tarka’s actions that led to the weapon being detonated. With Captain Burnham on his side to advocate for him, you’d think he’d know that he has a good chance of not getting into serious trouble – and he could even be a valuable asset to Starfleet, sharing his knowledge of Tarka and his plans.

Did anyone else find this moment of Book spying on Burnham a little creepy? Cool camera shot, though…

This continues a trend of Book having been fairly static for several episodes now, having gone through several stages of grief for Kwejian and his family before seeming to just… stop. In the first half of the season, Book got some of the most deeply emotional moments in the show, and seeing how grief was leading him down a dark path was a potentially interesting story, but it’s one that Discovery hasn’t really been able to successfully elaborate on. Like most of the rest of the characters, Book has been relegated to a supporting role, and that means he doesn’t really get much agency over the story any more. He’s stuck following Tarka just like everyone else is stuck following Burnham. If we’d heard anything from him to indicate that he was still committed to that cause, maybe it wouldn’t feel so silly. But right now, Book feels like a follower; a passive character caught in Tarka’s narrative wake.

So I’m not going to nitpick things like needing to physically board the ship to install a macguffin into the macguffin network. That’s Star Trek-ish enough to be inoffensive. But the setup that led Book and Tarka to that point felt very contrived, and it wasn’t sufficiently explained as to why they couldn’t just continue to tail Discovery all the way to – and perhaps inside – the hyperfield. It also wasn’t explained why everyone keeps assuming that the hyperfield will be impenetrable – they haven’t even tried to approach it, and if Unknown Species 10-C are as advanced as we think they are, surely they’d see a spaceship coming and investigate. Book and Tarka’s quest this week seems like an unnecessarily involved stealth mission that had the potential to lead to moments of either extreme drama or perhaps even comedy, with the two fugitives sneaking on board the ship, but it ultimately didn’t deliver much of either.

Book and Tarka managed to sneak aboard Discovery.

Bringing General Ndoye into the Book-Tarka side of the story is, again, something that we’ll have to watch and see whether it leads to a significant payoff. Right now it feels like it could go either way, and although I would argue that Ndoye had been the voice of reason earlier in the episode with Captain Burnham, I’m not wild about her becoming a kind of double-agent in this conspiracy.

Two of the big thematic elements of Seasons 3 and 4 have been connection and communication – and it seems like the series is now building to a conclusion which will say something like “if only Book and Tarka had worked with Captain Burnham, everyone could have got what they wanted.” If Book and Tarka would share why Tarka wants the power source, maybe Captain Burnham could work with him – or find an alternative way for him to travel between universes, such as the Guardian of Forever that we saw last season. And if Captain Burnham could find a way to compromise with Book, their whole relationship feud could be solved. A story about how division and failing to communicate can lead to problems can be a powerful one, but it’ll need to be executed a damn sight better than it was in Rosetta. Here, the two disconnected stories just chafed against each other in the most frustrating way.

The CGI work for Unknown Species 10-C’s planet was good, and although it was only seen very briefly and not really explained, I liked the “Dyson rings” seen orbiting their star. Presumably Discovery scanned the rings off-screen and determined there’s nothing worth looking for there… although that would have been nice to get confirmation of, otherwise the rings seem a good target for an away mission of this nature as well.

The filming location for the outdoor sections of the away mission looked very familiar; I’m sure it was seen either earlier in Season 4 or perhaps in Season 3. In an interview for The Ready Room a few weeks ago, Mary Wiseman mentioned a quarry in the Toronto area that has been used for several outdoor shoots, which could be why it’s so familiar. Slapping a yellow filter on it in post-production didn’t really do much to disguise it, and with the new AR wall that Paramount invested a fair amount of money in, I’m left wondering why the Star Trek franchise keeps walking headfirst into this particular mistake. The AR wall was used to great effect to depict the interior of the Unknown Species 10-C base… so why not the exterior as well?

The away team.

The crew’s EV suit malfunction is also a bit of a contrivance. Aren’t protective suits meant to protect against everything in the environment, especially things that are new or haven’t been encountered before? This is another nitpick, I guess, but I didn’t like the way that this was just hand-waved away by half a line of dialogue. “Oh, I guess the EV suits don’t protect against substances that aren’t in the Federation database and are very different.” That just seems like an odd way to explain it. And if we want to keep nitpicking, that dust looked like it was everywhere – floating in the air as well as lying on the ground and on surfaces. So how did Detmer not get exposed when everyone else did?

After making the decision to waste time on an away mission that, realistically, she must’ve known had the possibility of failure, Captain Burnham came across as incredibly stubborn shortly before the crew encountered the 10-C nursery. Partly this was triggered by a reaction to the hydrocarbons, I guess, but coming after I found her decision to go on the mission in the first place difficult to justify, stubbornly doubling-down on it when it seemed as though there wasn’t anything to find wasn’t a great look for her character.

So have we just nitpicked Rosetta to death?

There were interesting and clever concepts buried here, and there were some nice but unspectacular character moments between Dr Culber and Captain Burnham, Tarka and Book, and to a lesser extent between Reno and Adira and Detmer and Adira too. Some fans argue that Discovery is all about its characters and that the sci-fi trappings should just be seen as a backdrop, with any contrivances and plot complaints waved away because of how well-done some of these character moments can be. I don’t agree with that – if you want character drama, go and watch a soap or some scripted reality show. Star Trek is science fiction, so at the very least the sci-fi side of the story has to be basically competent and good enough to keep my suspension of disbelief going.

Because of how Rosetta sidelined many of the other characters and didn’t actually spend that much time on these interpersonal moments, I would argue that it wasn’t even a particularly impressive episode on the character side of things, either. The moment between Dr Culber and Captain Burnham came in two parts – one during the away mission and one at the end in her ready-room. But it lasted all of two minutes, maybe, and that just isn’t enough time to do justice to a complicated mental health story.

Counselling for the counsellor.

Dr Culber’s storyline feels like it’s retreading the Detmer path from Season 3. We’ve had a few short scenes spread across a handful of episodes to explain in the most basic of ways how he feels overwhelmed, stressed, and/or unable to cope with his work and the situation he’s found himself in. His moment admitting to Captain Burnham that he isn’t okay should have been the culmination of this season-long character arc… but it’s an arc that feels so underdeveloped that, despite the beautiful performance by Wilson Cruz, I’m struggling to buy it. The story of a counsellor – someone working as a mental health professional – needing to seek help for their own struggles is a noble one, and one absolutely worth telling, but it’s also a story that Discovery is not doing justice to as things stand.

I’ve been a big advocate for better mental health representation in all forms of media, but I’m unfortunately in the position of having to say that if the series can’t do justice to stories like this I’d honestly rather that it skipped them altogether. It feels like Discovery is doing little more than paying lip service to a serious topic, one that’s clearly too big for the limited time and attention that the show is willing to dedicate to it.

Captain Burnham and Dr Culber during the away mission.

Returning to Detmer, last season she got a storyline about post-traumatic stress that was referenced in Rosetta. But like Dr Culber’s story of dealing with his struggles this season, it wasn’t fleshed out enough to be meaningful. She had a few scenes spread across a handful of episodes, then seemed to magically “get better.” It’s only now, a full season later, that we even heard about her getting help or treatment for PTSD.

In Rosetta, Discovery also continued a disappointing trend of ham-fistedly inserting blatantly expository dialogue that the writers sometimes use as a substitute for actual character development. In this case, Detmer remembered something about her father mistreating her that could have been significant, but it was treated as an afterthought by a script that had its attention firmly focused elsewhere. Emily Coutts did well with the material she had, and put in a decent performance – but the material was barebones to say the least.

Lieutenant Commander Detmer.

Saru’s panic attack was one of the more interesting moments of characterisation, and if I were to single out one performance and one strong element from Rosetta it would be the way Doug Jones conveyed Saru’s terror during these sequences. We’ll have to set aside questions of why Captain Burnham didn’t immediately send him back to the shuttle, but if we can ignore contrivances like that, Saru really sold me on his panic attack. As someone who has had panic attacks myself – thankfully infrequently – I found the depiction of Saru in these moments very relatable.

We got a bit of a pep talk between Reno and Adira; two characters who don’t feel like a natural pair but who worked well together this time. Adira has adopted much of the awkwardness of Season 1 Tilly, and that “young, inexperienced, and nervous” character type is a good counterbalance to some of the show’s older and more established characters. Reno was deadpan as ever, but none of her lines this week were laugh-out-loud funny; while her scenes brought some much-needed levity to the story, they didn’t exactly blow me away.

Finally, we come to Dr Hirai. For the second episode running – and he’s only been in two episodes so far – he felt very underused. There was a brief scene between him and President Rillak in which she rebuked him for his bluntness, but that was it. Perhaps that was deserved, but as we’ve spent such a minuscule amount of time with this character, it just felt like an unnecessary addition. If Dr Hirai was going to be featured in a scene this week, why not show him working or doing something that could contribute to the story? Just because everyone aboard Discovery was sitting around waiting for Burnham to get back that doesn’t mean he couldn’t have found something useful to do.

Again, Dr Hirai is someone who could have a bigger role to play before the season ends. But his two appearances so far in Rosetta and in The Galactic Barrier have felt like fluff; a potentially-interesting character about whom we know nothing of consequence. If he is going to have something significant to do in the next couple of episodes, we need to start seeing more from him very soon – otherwise he risks feeling rather flat.

Dr Hirai.

So that was Rosetta, I guess. Not the season’s high-water mark, unfortunately.

At the core of the episode there was an interesting idea, and the notion of Unknown Species 10-C being difficult to communicate with is a concept that could still work – if it’s properly executed in the two episodes that remain. But because The Galactic Barrier added an unnecessary time constraint to Captain Burnham’s mission, this side-quest felt more frustrating than exciting; I wanted to shout at Captain Burnham – and at Discovery’s writers – to just get on with the main story.

There were more than enough smaller narrative threads to pick at to unravel the episode’s entire story. Both the A- and B-plots were disappointing, and even where Discovery has been successful in the past – with moments of characterisation and communication – I was underwhelmed by what Rosetta had to offer. As we approach the final two episodes of the season, there’s a lot of work left to do to pull out a decent ending to this rather plodding story.

Star Trek: Discovery review – Season 4, Episode 10: The Galactic Barrier

Spoiler Warning: There are spoilers ahead for Star Trek: Discovery Seasons 1-4. There are also minor spoilers for Star Trek: Picard Season 1 and the most recent trailer for Season 2.

Don’t get confused! According to Star Trek, there are not one but two barriers in the galaxy: one around the centre called the “Great Barrier” and one around the edge called the “Galactic Barrier.” They are not the same thing, and Discovery took us to the outer edge this week, not the centre! Two barriers, one galaxy. I hope that clears it up for you!

After being underwhelmed by the last couple of episodes, mostly due to their heavy focus on Captain Burnham’s angst over the situation with Book, The Galactic Barrier came along like a breath of fresh air. Though it relies heavily on the DMA and Unknown Species 10-C storylines, it came across on screen as two almost standalone sci-fi adventures, one starring Captain Burnham, President Rillak, and the crew of the USS Discovery, and the other focusing on Book and Tarka as they tracked down a rare element that they needed to cross the galactic barrier.

Both of these stories worked incredibly well for me, and showcased how strong Discovery can be when it doesn’t overdo the character drama. This isn’t a soap opera – and when the show’s writers get the right balance between fun sci-fi antics and intimate character moments, we’re treated to what I genuinely believe is some of the best science fiction ever brought to screen – and some of the best Star Trek, too.

The central character pairings of Book and Tarka on one side and President Rillak and Captain Burnham on the other worked brilliantly this week, and when the adventures paused to spend time on these character relationships, it was a welcome break from the incredibly drawn-out conflict between Book and Burnham that had dominated the past two episodes to the detriment, I would argue, of other aspects of the season’s storyline.

Captain Burnham got a much-needed break from Book this week.

I wrote last week that the DMA/Unknown Species 10-C story was unfolding in a very similar way to the Burn last season – and, to an extent, Control and the Red Angel in Season 2 as well. Discovery is definitely still flirting with repetitiveness in that regard, but with The Galactic Barrier telling these two semi-standalone stories of the mission to cross the Galactic Barrier and Book and Tarka’s antimatter harvest, at the very least we got a bit of a break from that feeling of déjà vu that had been present.

Let’s get what is perhaps the least impressive part of the story out of the way first: Earth being in danger is such a played-out cliché in stories like these. It was hard to avoid rolling my eyes when Admiral Vance’s holographic message dropped that particular bombshell, and I find myself repeating something I’ve said about Discovery on several occasions in Season 4, Season 3, and all the way back to the beginning: the show is strong enough and its storylines are interesting enough in their own right that there’s no need for this. Falling back on tired tropes doesn’t really do anything to ramp up the tension; the mission to contact Unknown Species 10-C is already sufficiently tense, exciting, and dangerous that there’s nowhere left to go.

Admiral Vance’s holo-message.

For me, this wasn’t so much an epic fail as a piece of unnecessary fluff. I wish Discovery’s producers and writers had more confidence, sometimes, in the stories they want to tell. When a fictional setting is built up as well as Star Trek’s, and when we already know the stakes involved thanks to what happened to Kwejian, there’s no need to put Earth in harm’s way – doing so almost detracts from the story, because now we know for absolute certain that Captain Burnham will find a way to save the day! If another planet was in danger – say, for example, the Breen homeworld or Bajor – the story could still go in any direction. We saw with the destruction of Kwejian that the writers are happy to blow up planets. But when it’s Earth, far from feeling like the planet is in serious danger and Captain Burnham might not be able to save it in time… now I’m left with a sense that the story’s conclusion is an inevitability rather than a possibility.

But aside from that unsuccessful attempt at taking the stakes from a ten to an eleven, The Galactic Barrier was impressive all-around. The visual effects of the titular barrier were impressive, and it was a rare treat to see the USS Discovery at warp! I love the spore drive, don’t get me wrong, but warp drive has been a huge part of Star Trek going back to the beginning, so to see the USS Discovery at warp for what I think is the first time this season and only the second or third time since the end of Season 2 was beautiful. The updated look of ships at warp is absolutely fabulous, and I never tire of seeing it.

The USS Discovery at warp.

The Galactic Barrier had originally appeared in The Original Series, first in the show’s second pilot, Where No Man Has Gone Before, and again in the third season episode Is There In Truth No Beauty. The latter episode featured a pocket of space within the barrier, something that Discovery also used to great effect this week, which was a fantastic callback to the very beginnings of Star Trek.

Discovery has been criticised in the past for treading on the toes of the established canon of Star Trek. Some of that criticism is fair, some arguably is very nitpicky, but we’re getting off the subject! In The Galactic Barrier, Discovery didn’t overwrite anything but instead expanded on our knowledge of how this unusual phenomenon works. Using the way the Galactic Barrier had been set up in The Original Series as a baseline, the episode took the concept and fleshed it out, explaining why travelling through it is so difficult and showing why it hasn’t been attempted in such a long time. As the Star Trek franchise continues to grow, I’d like to see more of this kind of thing. Picking up an element from the franchise’s past and looking at it in more detail without overwriting what came before is incredibly rewarding for long-time viewers, and I hope that other Trekkies who enjoyed The Original Series are as impressed as I am with Discovery’s approach this week.

The Galactic Barrier was visually impressive.

I was wrong in my theory that Ruon Tarka’s friend was someone we might be familiar with… and I have to say that I’m a little confused by the way this unfolded. I always caveat my theories by saying that they probably won’t pan out and that getting too attached to fan theories is a bad thing, and I also said from the beginning that I might well be overreaching by suggesting potential crossover characters for Tarka’s friend. But as we moved through three episodes with this individual’s identity being deliberately hidden by Discovery’s writers, I felt increasingly sure that there must be a reason.

The revelation that the character of Oros was someone brand-new is fine, and I actually like the relationship between he and Tarka that The Galactic Barrier showed us in flashback form. There was a sweetness to Tarka that we haven’t really seen before, and a hint – just a hint, at this stage – that the relationship goes beyond mere friendship. All of that is totally fine, and is even good; it adds dimension and complexity to Tarka and helps turn him from a villain into an antihero we can root for. But I have to question why this character’s identity was so carefully hidden until this episode. What was the point? Was it just to throw out a red herring, to send fans like me into theory-crafting overdrive? If so, that seems a little cruel. It just feels like naming Oros as far back as But To Connect wouldn’t have done any harm to the flashbacks in The Galactic Barrier, and that there wasn’t any reason to go to such lengths to keep Oros’ name and identity a secret for so long.

Ruon Tarka’s “friend,” Oros.

Since Tarka’s first appearance in The Examples earlier in the season he’s been much more than just a “mad scientist” character trope. His characterisation may have begun with that archetype, but the complex and nuanced character that we’ve come to know is so much more than that. We saw this week how he dealt with defeat: his weapon had failed to get him the power source he’s so desperately seeking, and through the flashbacks with Oros and his conversations with Book, we also saw how he’s a genuinely loving and caring person, willing to go to extremes to reach someone he cares about. In a series that has been all about finding and holding onto connection, Tarka fits the mould in a different way, but no less of an important or impactful one.

The relationship between Book and Tarka is evolving, too. Tarka had been in control for much of their time together, dictating how the weapon would be built, what components he needed, and so on. But this week we saw Book take back control – firstly by threatening to kick Tarka off his ship, and secondly by demanding to know the full story of what happened with Oros and what’s driving him.

Book and Tarka make a great character pair.

Book has been pretty static the past few episodes; his development this season came earlier as he grieved for Kwejian, leading up to his betrayal and team-up with Tarka before the mid-season break. And I don’t think we saw a lot in The Galactic Barrier to further develop or explore the extent of Book’s grief or how he’s dealing with his feelings of loss, but what we did get was someone trying to reassert himself and regain control of a situation that I’m sure even he would admit has spiralled out of control.

Despite his complex relationship with Tarka, finding out more about the man he’s stuck with seemed to be important to Book, and the revelation of Tarka’s past seems to have solidified their partnership, at least in the short-term. It would have been possible for Book to take the antimatter and ditch Tarka if he’d wanted to; he seems to recognise that, at least for now, it’s in his interests to continue to work together. I suspect that there will be some pay-off to this if and when the pair make it across the Galactic Barrier – and I’m still rooting for Tarka to find a way to reach Oros. In spite of his misdeeds (or perhaps because of them), I find him a strangely relatable character.

Tarka in one of the flashback sequences.

One thing that wasn’t addressed in The Galactic Barrier was the status of Book and Tarka. Are they fugitives now, having detonated their weapon? Is Book in less trouble than Tarka having indicated his willingness to stand down? It seems as though Book assumes he needs to remain off the grid, otherwise I would’ve expected him to have at least tried to reach out to Burnham; their parting of the ways in Rubicon seemed to suggest a middle ground between them was possible, and from there perhaps even a pathway to reconciliation. I’m sure Discovery will address this before the end of the season, but it was interesting that Book and Tarka’s status wasn’t really discussed here.

One thing that’s baffled me ever since it was announced a few weeks ago is the scheduling of the next few episodes of Discovery. They will overlap with the first three episodes of Picard Season 2… and on a streaming platform I just don’t get why that is. This is something that I’ll address in more detail in my next theory post, but I wonder if there’s a possible crossover on the cards and that’s why the weird scheduling has happened. If so, perhaps we got the very first hint at it in The Galactic Barrier, with a reference made about Vulcans observing Earth prior to official first contact taking place. This could be a reference to the events of the Enterprise episode Carbon Creek, but it could also be an oblique reference to something we’re about to see in Picard Season 2 – the most recent trailer showed off a Vulcan (or perhaps a Romulan) on what appeared to be 21st Century Earth. We’ll dig deeper into this possible crossover in my theory post in the days ahead, so stay tuned for that!

A Vulcan (or possibly a Romulan) on Earth in what appears to be the 21st Century as seen in the recent Picard Season 2 trailer.

The burgeoning relationship between Saru and T’Rina took a turn this week, with Saru responding to T’Rina’s earlier invitation to dinner. There’s something adorable about the way both of these characters behave; they’re clearly not used to reaching out to someone else in this way, and the almost teenage awkwardness of asking someone out and worrying about saying the wrong thing is made so much cuter by the fact that they’re both usually so calm, wise, and stoic.

I’m glad that Discovery has given this kind of new relationship to Saru. It would’ve been easy, in a series with a lot of relationship drama coming from its protagonist, to either completely ignore the possible relationships between other characters or to give them easy, comfortable, safe relationships that don’t take up a lot of screen time. Discovery learned the hard way from messing with the Stamets-Culber relationship that these things don’t always come across well on screen, so taking a bit of a risk here with Saru and T’Rina is bold – and it’s working exceptionally well, injecting some lighter moments into a series that can be very heavy at points. It’s also sweet to see Dr Culber helping Saru as he takes these first steps into his very own new frontier; they work so well as a pair in these moments.

T’Rina and Saru.

So who do we think the Federation Vice President is? My money is on Kovich right now; I don’t see another plausible candidate among the very limited Federation HQ minor characters, and there was something about the way that President Rillak and Admiral Vance went out of their way to avoid using the VP’s name that makes me think that there could be a significant revelation to come. Kovich has remained ambiguous since we met him in Season 3, and although he went through some significant growth this season, particularly in episodes like All Is Possible, the events of The Galactic Barrier seem to have placed him right back in that mysterious space.

What is Kovich doing that’s more important than dealing with Unknown Species 10-C? And will this be paid off at all, or was it just a conveniently ambiguous line to move him out of the way so President Rillak could go on the mission? Sometimes it feels like Discovery has a plan with these moments, but then when the story ends and the dust settles, they turn out to be nothing more than throwaway lines! So right now I feel that there should be something bigger going on with Kovich – and again I’ll take a look at a couple of possibilities in my upcoming theory post – but at the same time, Discovery’s track record, and the fact that there are only three episodes left, makes me question whether we’ll see anything for ourselves.

Dr Kovich… Vice President of the Federation?

In a way, I enjoy Kovich’s ambiguity and the somewhat mysterious nature of his role within the hierarchy of the Federation. Speculating is always fun, but at the same time if Kovich’s position was fully explained and his role fleshed out, there’s a chance he might lose what has made him such an interesting part of the show over the past couple of seasons. I had initially pegged Kovich as a villain, perhaps a Section 31 leader or something like that. But episodes like But To Connect showed off that he at least appears to be committed to Federation principles, so I’m not sure about that any more, and I even struck the “Kovich is Section 31” theory off my list a few weeks ago.

We’ll save the guesswork for my theory post, but suffice to say I can think of a few reasons – both good and evil – for what role Kovich might play and why he might’ve chosen to recuse himself from the mission through the Galactic Barrier. I hope that, whatever’s happening with him, we don’t lose him as a character by the end of the season. With Discovery returning for a fifth season, I would hope Kovich could stick around for more ambiguous adventures!

Kovich and the rest of the senior officials.

Speaking of Kovich, it was said on several occasions this season that Lieutenant Commander Bryce is working closely with him, and he got a scene this week in which he parted ways with Saru that was very sweet. Although Bryce has been a secondary character, his goodbye with Saru hit all of the emotional notes that I might’ve expected from a major character, and this scene genuinely felt like two good friends parting ways, knowing that it could well be for the final time.

There weren’t that many characters with whom we could’ve gotten similar scenes, so in that sense it’s logical to use Bryce here – and actor Ronnie Rowe Jr. put in a beautiful performance opposite Doug Jones. The pair really sold me on this moment, and it was a surprisingly emotional scene given that Bryce has never been the focus of a major story across the show’s four-season run to date. Again, this is something to speculate about in-depth next time, but I wonder if Discovery plans to pay off Bryce’s story of working with Kovich in some way. Perhaps the two of them will work together to save the day… or perhaps Bryce won’t survive, and this moment with Saru was the equivalent of his goodbye to the series and to us as the audience!

Are we about to say goodbye to Bryce?

I stand by what I’ve said about President Rillak in her past appearances: she’s a hard-nosed politician with a Machiavellian edge, willing to use other people to manipulate events to get the outcome she’s looking for. But this week we saw – dare I say – an almost altruistic side to the Federation’s President, as she delegated power to her Vice President and accompanied the USS Discovery on its mission through the Galactic Barrier.

It’s still possible, in my view, that Rillak has an ulterior motive here. But at the same time, it was nice to see her recognising her mistake from the season premiere – in which her questioning and time-wasting on the bridge in the middle of a crisis was completely out-of-line… and arguably got poor Commander Nalas killed. Some characters on Discovery have arguably been less good at recognising their own mistakes and learning from them, so this was something nice to see; a moment of (apparent) contrition from a wonderfully complex character. As she has done all season long, Chelah Horsdal absolutely nailed it.

President Rillak joined the mission.

Captain Burnham showed last week that she has a weakness when it comes to Book – understandably so. But that weakness definitely had an impact on her ability to command her ship level-headedly, to such an extent that Nhan was given authority to overrule her if it came down to the wire. This week, with Book effectively out of the picture, we got to see a much more composed Captain Burnham, and she remained fully in control of the ship and crew as they made their way through the Galactic Barrier.

For me, this hammers home why the whole relationship drama angle that Discovery has aggressively pursued for the last few weeks is such a mistake. Captain Burnham is at her best when she’s composed and in control, able to draw on her inner strength to be the kind of leader that we know she can be. When she’s distracted unnecessarily by a fairly pedestrian and poorly-written soap opera-inspired boyfriend angst storyline, we don’t see her at her best. Female characters – especially leading characters like Captain Burnham – are done a disservice by the show’s writers and creatives if all they’re permitted to do is sit around and worry about the men in their life. By cutting the crap this week and focusing on what was a fun sci-fi adventure story in its own right, Discovery once again allowed Captain Burnham to shine.

Stepping away from Book was good for Captain Burnham this time.

Discovery presented Captain Burnham and President Rillak with a complicated question after Admiral Vance’s holo-message arrived. There isn’t an easy, clear-cut answer in situations like these, and I can understand both Captain Burnham’s position of wanting to share the news about the danger to Earth and Ni’Var with the crew so they know the full picture and understand the stakes, but also from a practical point of view, I can understand President Rillak’s wish to keep the information private, at least in the short-term.

President Rillak wanted to avoid losing control of the situation, which is understandable psychologically for someone in a position of authority. But more so I think her point about not wanting to leave the crew with an unnecessary distraction that could interfere with their work is a valid one; at the very least, waiting until the dangerous mission to navigate the Galactic Barrier was complete seems like a perfectly reasonable and sensible position to take.

President Rillak and Captain Burnham.

Because this is Discovery, though, and despite all the talk last week of “finding a middle ground,” Captain Burnham had to win this particular argument, and after a conversation with President Rillak, the news was ultimately shared with the crew and the assembled delegates. I like, however, that they waited until the most dangerous part of the mission had concluded before doing so – it feels like somewhat of a compromise under the circumstances.

It was interesting to learn that the mycelial network doesn’t extend beyond the edge of the galaxy. The network seemingly connects at least two parallel universes – the prime and Mirror – so it seems odd that it has this limitation. Obviously, though, for the sake of the story a way around the spore drive had to be found, but it does feel at least slightly inconsistent with previous statements about the mycelial network spanning an entire multitude of universes. This is really just a nitpick, though, in the grand scheme of things, and the mycelial network being a galactic phenomenon allowed Discovery to tell one of the most exciting and interesting stories of the season so far.

Dr Hirai.

I’m interested to learn more about Dr Hirai, the new character introduced in this episode, but he ultimately didn’t get a lot to do on this occasion. The talk of universal translators and making assumptions about Unknown Species 10-C was all very interesting, but until we actually get to see this faction for ourselves it was a bit of background that may or may not come into play… and it feels like it was there as an excuse to show off some combadges and other props more than anything else!

So I think that’s about all I have to say this week. The Galactic Barrier was one of the best episodes of Season 4 so far, telling two distinct stories that took our characters to some very different literal and thematic places. The sci-fi adventure of overcoming the odds to navigate a dangerous phenomenon was a ton of fun, and stepping away from the show’s recent focus on Captain Burnham and Book allowed both characters some much-needed breathing space. The show itself took advantage of this, too.

I had a ton of fun with The Galactic Barrier, and it’s an episode that I’ll happily rewatch for its semi-standalone adventure story when the season is over. With only three episodes remaining, surely we’re close to learning who Unknown Species 10-C are… right?

Star Trek: Discovery theories – week 9

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

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

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

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

Confirmed theory:
Tarka’s weapon will be successful.

Kaboom!

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

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

Tarka launched his weapon.

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

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

So that theory was confirmed.

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

Debunked theory #1:
Nhan works for Section 31.

Nhan in Rubicon.

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

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

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

Tarka and Book working on the isolytic weapon.

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

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

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

The DMA in Rubicon.

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

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

So those theories have been debunked!

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

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

The USS Enterprise approaching the galactic barrier.

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

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

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

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

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

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

The Galactic Barrier on the USS Enterprise’s viewscreen.

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

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

Traversing the Galactic Barrier could be very dangerous…

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

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

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

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

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

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

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

Could Unknown Species 10-C be the Kelvan Empire?

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

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

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

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

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

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

Book and Burnham are currently separated.

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

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

Book and Burnham in All In.

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

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

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

Captain Burnham in Rubicon.

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

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

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

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

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

Theory #7:
Tarka will create his own DMA.

Tarka, Stamets, and Saru with the DMA model.

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

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

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

The second DMA in Rubicon.

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

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

So those theories are new or saw movement this week.

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

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

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

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

Captain Burnham believes this image depicts a “supernova.”

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

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

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

Abronian stasis pods.

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

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

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

A deceased Abronian.

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

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

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

“That’s no moon…”

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

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

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

A Red Angel suit in Season 2.

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

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

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

Captain Saru in command… of a shuttle!

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

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

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

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

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

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

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

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

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

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

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

The dilithium planet is vital to the Federation.

This one is definitely hanging by a thread right now. Season 4 continues to unfold in a very different direction, largely ignoring the main story beats from Season 3. But the dilithium shortage has been mentioned more than once, and as things stand right now, the Federation is in control of the galaxy’s only significant dilithium supply. The Verubin Nebula is almost certainly going to be a target – even if Unknown Species 10-C don’t care about it.

It begins to stretch credulity to think that all of the belligerent factions and races present in the galaxy would become aware of the Federation controlling this impossibly valuable resource and wouldn’t want to take it for themselves. And while it may not happen now until after the DMA storyline has run its course, I think sooner or later someone is going to want to steal the Verubin Nebula and its dilithium. Maybe it will be at the end of Season 4, maybe it will be in Season 5… who knows?

Theory #15:
A major character will be killed off.

A Starfleet coffin seen in Deep Space Nine.

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

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

Theory #16:
Season 4 will connect with the Short Treks episode Calypso.

Zora dancing with Craft in Calypso.

Zora’s status as a member of the crew was confirmed in But To Connect, and this followed her developing emotions and sentience earlier in the season. Zora is now much closer to her presentation in Calypso, potentially bringing the story of the Short Treks episode one step closer.

There are still significant hurdles to overcome if the story of Calypso is to be wrapped up in Season 4, though. Obviously we have the timeframe issue: will the USS Discovery be sent back in time, be abandoned, or is Calypso taking place centuries in the future? Then we have the USS Discovery itself – it’s been retrofitted since arriving in the 32nd Century, and now looks very different to how it did in Calypso. I’m not sure how Discovery will overcome these hurdles – but it’s possible. Zora hasn’t had a significant role to play in the last couple of episodes, but earlier in the season we definitely saw movement in this direction.

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

Star Trek has had some wonderful crossovers in the past.

Tarka’s friend could, as mentioned, be someone we’ve already met. But there are other ways to bring back a character from a past iteration of the franchise – and there would be many potential benefits to doing so! I had initially proposed a version of this theory in the run-up to Season 3 that centred on the Doctor from Voyager – but with some creative technobabble, practically anyone could be included, despite the leap forward in time.

Choose To Live showed us the Abronians in cryo-sleep, and Stormy Weather saw the crew of Discovery use the transporter buffer to survive – just like Scotty had done in The Next Generation Season 6 episode Relics. Could these be hints at something to come?

It would also be possible for Captain Burnham to discover the logs or a holographic recording of a long-dead character – and while this would be less of a “crossover,” it could still be a ton of fun and great fan-service!

Theory #18:
Some areas of the galaxy – such as the Delta Quadrant – avoided the worst effects of the Burn.

Adira and Stamets with a map of the Milky Way galaxy.

In But To Connect, President Rillak told us that the diplomatic summit she convened would bring together races from “all four” quadrants. Assuming she was referring to the familiar Alpha, Beta, Gamma, and Delta Quadrants that make up the Milky Way galaxy, this would count as our first mention of the Delta Quadrant in the 32nd Century. I didn’t spot any familiar Delta Quadrant races (or their emblems) amongst the assembled delegates, however!

I had previously speculated that the Burn may not have affected the entire galaxy equally, and that regions farthest away from the Verubin Nebula may have survived without much damage. I still think that this is a possibility – though whether Discovery will revisit the Burn in any depth, or visit the Delta Quadrant at all, remains unclear.

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

Theory #19:
Tarka aims to travel to the Kelvin universe.

The USS Kelvin.

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

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

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

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

In Star Trek: Generations, Captain Picard encountered Captain Kirk inside the Nexus – despite Kirk being declared “dead” after the Enterprise-B encountered the energy ribbon almost eighty years earlier. Now that we know a little more about how the DMA operates, it seems at least faintly possible that, just like Captain Kirk, the inhabitants of Kwejian may not be as dead as they first appear.

This theory is, I freely admit, a bit of a long-shot. But the wormhole technology that we know the DMA uses seems to be capable of sending some of what it harvests or mines back to Unknown Species 10-C’s base of operations. Maybe that means that some of the people from Kwejian were transported there instead of being killed.

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

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

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

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

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

President Rillak, leader of the United Federation of Planets.

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

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

President Rillak with Captain Burnham on Ni’Var.

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

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

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

R.I.P.

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

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

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

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

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

So that’s the main theory list!

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

Production-side theory #1:
Tilly’s departure will be permanent.

Tilly’s departure feels permanent.

Mary Wiseman confirmed in an interview with Wil Wheaton on The Ready Room (Discovery’s social media aftershow) that Tilly will be seen again before the end of Season 4, and we glimpsed her in the trailer for the second half of the season as well. But that doesn’t mean she will return as a main character on the show going forward, and her departure in All Is Possible felt permanent. Despite that, I’ve seen quite a lot of folks online who don’t believe that Tilly is actually leaving the series – so I wanted to put it out there officially and say that, in my opinion anyway, she is.

Maybe those people know something that I don’t! As I always say, I don’t have any “insider information;” all of this is just speculation on my part. However, I feel that the manner of Tilly’s departure, the fact that she got that emotional sequence with Captain Burnham, a montage showing her leaving the ship, Adira seeming to take over several of her roles, and her departure feeling like the culmination of her arc going back to the latter part of Season 3 all come together to strongly indicate that she won’t be back as a major character. She may yet have a significant role to play in a future Season 4 episode, as has been suggested, but unless Discovery’s writers are really playing with our emotions I believe we’ve seen Tilly’s end as a main character on the show. She may come back in a future Starfleet Academy series, though… so watch this space!

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

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

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

So that’s it!

The USS Discovery inside the DMA in Rubicon.

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

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

Star Trek: Discovery Season 4 is available to stream now on Paramount+ in the United States, Scandinavia, Latin America, and Australia. The show is on Pluto TV in the UK, France, Germany, Italy, and other parts of Western Europe at 9pm on Fridays and Saturdays. Individual episodes or the full season can be purchased on iTunes, Amazon Video, Google Play, and possibly other platforms in the UK, parts of Europe, and select other countries.

Star Trek: Discovery theories – week 8

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

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

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

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

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

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

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

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

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

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

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

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

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

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

So those theories were confirmed and debunked.

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

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

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

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

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

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

Isolynium – a key component of Tarka’s weapon.

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

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

Tarka and Book.

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

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

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

R.I.P.

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

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

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

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

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

Theory #4:
Nhan works for Section 31.

Nhan.

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

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

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

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

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

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

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

Burnham and Book in All In.

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

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

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

“It’s alive!”
Frankenstein (1932)

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

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

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

Could it be the Borg?

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

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

How about Species 8472?

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

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

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

President Rillak, leader of the United Federation of Planets.

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

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

President Rillak with Captain Burnham on Ni’Var.

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

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

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

Captain Burnham.

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

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

Burnham in The Examples.

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

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

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

The Guardian of Forever as it originally appeared.

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

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

Theory #12:
Tarka will create his own DMA.

Tarka and Stamets with their DMA model.

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

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

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

Stamets, Tarka, and Saru with the DMA model.

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

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

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

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

In Star Trek: Generations, Captain Picard encountered Captain Kirk inside the Nexus – despite Kirk being declared “dead” after the Enterprise-B encountered the energy ribbon almost eighty years earlier. Now that we know a little more about how the DMA operates, it seems at least faintly possible that, just like Captain Kirk, the inhabitants of Kwejian may not be as dead as they first appear.

This theory is, I freely admit, a bit of a long-shot. But the wormhole technology that we know the DMA uses seems to be capable of sending some of what it harvests or mines back to Unknown Species 10-C’s base of operations. Maybe that means that some of the people from Kwejian were transported there instead of being killed.

So those theories are new or saw movement this week.

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

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

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

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

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

Theory #16:
Some areas of the galaxy – such as the Delta Quadrant – avoided the worst effects of the Burn.

Adira and Stamets with a map of the Milky Way galaxy.

In But To Connect, President Rillak told us that the diplomatic summit she convened would bring together races from “all four” quadrants. Assuming she was referring to the familiar Alpha, Beta, Gamma, and Delta Quadrants that make up the Milky Way galaxy, this would count as our first mention of the Delta Quadrant in the 32nd Century. I didn’t spot any familiar Delta Quadrant races (or their emblems) amongst the assembled delegates, however!

I had previously speculated that the Burn may not have affected the entire galaxy equally, and that regions farthest away from the Verubin Nebula may have survived without much damage. I still think that this is a possibility – though whether Discovery will revisit the Burn in any depth, or visit the Delta Quadrant at all, remains unclear.

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

Star Trek has had some wonderful crossovers in the past.

Tarka’s friend could, as mentioned, be someone we’ve already met. But there are other ways to bring back a character from a past iteration of the franchise – and there would be many potential benefits to doing so! I had initially proposed a version of this theory in the run-up to Season 3 that centred on the Doctor from Voyager – but with some creative technobabble, practically anyone could be included, despite the leap forward in time.

Choose To Live showed us the Abronians in cryo-sleep, and Stormy Weather saw the crew of Discovery use the transporter buffer to survive – just like Scotty had done in The Next Generation Season 6 episode Relics. Could these be hints at something to come?

It would also be possible for Captain Burnham to discover the logs or a holographic recording of a long-dead character – and while this would be less of a “crossover,” it could still be a ton of fun and great fan-service!

Theory #18:
Season 4 will connect with the Short Treks episode Calypso.

Zora dancing with Craft in Calypso.

Zora’s status as a member of the crew was confirmed in But To Connect, and this followed her developing emotions and sentience earlier in the season. Zora is now much closer to her presentation in Calypso, potentially bringing the story of the Short Treks episode one step closer.

There are still significant hurdles to overcome if the story of Calypso is to be wrapped up in Season 4, though. Obviously we have the timeframe issue: will the USS Discovery be sent back in time, be abandoned, or is Calypso taking place centuries in the future? Then we have the USS Discovery itself – it’s been retrofitted since arriving in the 32nd Century, and now looks very different to how it did in Calypso. I’m not sure how Discovery will overcome these hurdles – but it’s possible. It feels like a proper link-up with Calypso is edging closer week by week.

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

Spock’s funeral in The Wrath of Khan.

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

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

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

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

The dilithium planet is vital to the Federation.

Despite having grown to sixty member worlds, the Federation is still in a weakened state and isn’t yet back to full strength. The Verubin Nebula is thus a very tempting target for anyone looking to gain an edge in a galaxy where dilithium is still in short supply. As the only known significant cache of the valuable fuel, whoever controls the Verubin Nebula will have a massive tactical advantage.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Theory #25:
We haven’t seen the last of the Abronians.

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

Theory #25 A:
The Abronians’ homeworld was destroyed by the DMA.

Captain Burnham believes this image depicts a “supernova.”

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

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

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

Abronian stasis pods.

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

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

Theory #25 C:
The Abronians will return to help the Federation later in the season.

A deceased Abronian.

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

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

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

“That’s no moon…”

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

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

So that’s the main theory list.

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

Production-side theory:
Tilly’s departure will be permanent.

Tilly’s departure feels permanent.

Mary Wiseman confirmed in an interview with Wil Wheaton on The Ready Room (Discovery’s social media aftershow) that Tilly will be seen again before the end of Season 4, and we glimpsed her in the trailer for the second half of the season as well. But that doesn’t mean she will return as a main character on the show going forward, and her departure in All Is Possible felt permanent. Despite that, I’ve seen quite a lot of folks online who don’t believe that Tilly is actually leaving the series – so I wanted to put it out there officially and say that, in my opinion anyway, she is.

Maybe those people know something that I don’t! As I always say, I don’t have any “insider information;” all of this is just speculation on my part. However, I feel that the manner of Tilly’s departure, the fact that she got that emotional sequence with Captain Burnham, a montage showing her leaving the ship, Adira seeming to take over several of her roles, and her departure feeling like the culmination of her arc going back to the latter part of Season 3 all come together to strongly indicate that she won’t be back as a major character. She may yet have a significant role to play in a future Season 4 episode, as has been suggested, but unless Discovery’s writers are really playing with our emotions I believe we’ve seen Tilly’s end as a main character on the show. She may come back in a future Starfleet Academy series, though… so watch this space!

So that’s it!

Owosekun in the combat arena in All In.

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

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

Star Trek: Discovery Season 4 is available to stream now on Paramount+ in the United States, Scandinavia, Latin America, and Australia. The show is on Pluto TV in the UK, France, Germany, Italy, and other parts of Western Europe at 9pm on Fridays and Saturdays. Individual episodes or the full season can be purchased on iTunes, Amazon Video, Google Play, and possibly other platforms in the UK, parts of Europe, and select other countries.

Star Trek: Discovery theories – week 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 – 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.

A Borg drone seen in The Next Generation.

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.

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

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

There are also a couple of characters 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.

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

This is a controversial one, so let me just say up front that I’m neither in favour of this theory nor opposed to it – I just think it’s a possibility. As things stand, Discovery has had four different captains across its four seasons. One of the show’s unique points of interest within Star Trek’s broader canon are the 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 #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 on the surface of water. Ripples eventually diminish, fading away the further they travel, and perhaps that’s true of the Burn as well. There could be whole areas of the galaxy that didn’t even notice the Burn – and maybe the ship and crew will visit one such region.

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

Theory #18: The Guardian of Forever will be back.

Carl – the Guardian of Forever’s new persona.

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

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

So that’s it! Those are all of the theories I currently have in play.

Stay tuned for weekly updates to this list after new episodes air! I try very hard to publish my theory updates in between episodes so that nothing is out-of-date! Season 4 is off to an exciting start – and there are plenty of mysterious elements to get stuck into.

Star Trek: Discovery Season 4 – Death Predictions…

Spoiler Warning: There are spoilers ahead for Star Trek: Discovery Seasons 1-3 and the trailers and teasers for Season 4.

A bit of a morbid one this time… but it is nearly Halloween!

In the last decade or so, a number of television shows have pioneered what I call the “disposable cast” – where even main characters and fan-favourites can’t be assured of safety or survival as a series continues. Shows like Game of Thrones and The Walking Dead have made this a big part of their identities, and the idea that any major character could be in danger can – when done right – add to the tension and drama. Not knowing if your favourite character will make it to the end of the episode or escape a dangerous situation can really increase the weight of a story.

Discovery has technically seen more main cast members depart than any previous Star Trek series! Captains Lorca and Pike, Spock, Georgiou, Tyler, and Nhan were all main cast members at one point before departing the series. But with the exception of Lorca, none of these characters were killed off, and in a television landscape that increasingly favours big, dramatic character deaths, the Star Trek franchise as a whole still hasn’t really caught up.

Sonequa Martin-Green starred in The Walking Dead for a time.

In Season 3 we saw the recurring character of Ryn killed off. He’d been a friend and ally to Booker and Burnham and his death was both a shock – due to the way it was carried out – and a tragedy for the crew. As with Airiam in Season 2, though, Ryn wasn’t a character we’d got to know particularly well before his death, and when Season 3 could have stepped up and actually killed off a main character or a character who’d been present on the show since the beginning, the writers and producers chose not to do so.

Star Trek has always had an optimistic tone, embodied in some ways by Captain Kirk’s assertion that he “doesn’t believe in no-win scenarios.” The desire to save everyone every time is drilled into every Starfleet officer – particularly captains. In that sense I can certainly entertain the argument that a character death feels like a loss or a defeat in a way that is somehow “un-Star Trek.”

Admiral Kirk in The Wrath of Khan. He famously refused to accept the concept of a no-win scenario.

At the same time, I fundamentally disagree with Captain Kirk. Life is full of no-win scenarios, and one of the skills any captain or commander needs to have is knowing how to make a difficult choice; how to choose the least-bad option when no good outcomes are possible. Sometimes that means sacrificing a life to save others, and this is something that the Star Trek franchise has touched on in the past.

Though I don’t want to see any specific character killed off in Discovery’s imminent fourth season, a well-timed character death could go a long way to raising the stakes and making the story much more impactful. The gravitational anomaly would seem all the more deadly if it claimed the life of a familiar face, or the climax of the story could see Captain Burnham having to make an impossible choice.

I don’t necessarily want to see anyone killed off – but it would certainly make for an impactful and dramatic story beat.

So this time we’re going to take a look at Discovery’s main and recurring characters – and try to assess who may or may not survive the season!

The usual caveats apply: I have no “insider information” and I’m not claiming to know what will happen. All of this is guesswork and speculation from a fan of Star Trek, nothing more. It’s also entirely subjective, so if you disagree or hate my ideas that’s okay!

Now that’s out of the way, let’s get started. I’m going to put the characters into a list, then give my assessment of how likely they are to be killed off during Season 4.

Character #1: Captain Michael Burnham
Status: Almost Certainly Safe 💖

Captain Burnham in a promo image for Season 4.

Discovery has been the Michael Burnham show since its premiere episode, and that is unlikely to change! The first three seasons saw Burnham’s rise to the captaincy of the USS Discovery, and having only just got there it would be a really unexpected and subversive twist to kill her off. As the show’s main protagonist she feels safer than most – and even series that pioneered the “disposable cast” like those mentioned above have tended to save their most significant characters from harm.

The only possible argument we could consider to counter that is the uniqueness of the USS Discovery’s captain’s chair. Three seasons of the show have each been led by a different captain – Lorca, Pike, and Saru. One of Discovery’s most interesting features has been these individual season-long captaincies and the very different styles each captain had. It’s possible – though I wouldn’t call it “likely” by any stretch – that the show might choose to bring in another new captain for Season 5, continuing this trend. If that’s the case, perhaps Captain Burnham isn’t quite as safe as it seems! However, I consider that a very unlikely scenario.

Character #2: Saru
Status: In Danger ☠️

Saru in the second Season 4 trailer.

What role does ex-Captain Saru have aboard a ship that has moved on without him? That’s a fundamental question that the series will have to address, because it’s quite odd for a Starfleet vessel to be racing across the galaxy with two captains on board. The situation could, perhaps, even lead to some awkwardness for Captain Burnham!

Some fans felt that Saru might’ve left Discovery after the Season 3 epilogue told us that he was returning to Kaminar to spend time helping Su’Kal. Fortunately that didn’t happen – not least because the short epilogue would have been a very disrespectful way for Saru to be shuffled off the show altogether! But the fact that Discovery has found a new captain means Saru doesn’t really have a role any more, at least not as things currently stand. Characters who feel surplus to requirements are often the most in danger – and Saru doesn’t really have a clear role right now.

Character #3: Paul Stamets
Status: In Danger ☠️

Stamets in the first Season 4 trailer.

Until recently, Stamets felt safer than almost any other character on Discovery! His unique ability to navigate the mycelial network meant that without him, one of Discovery’s unique selling points – the Spore Drive – wouldn’t work. For story reasons that could be a problem and certainly a limitation, so Stamets felt safe. But the revelation at the end of Season 3 that Booker – and any other empathic character, in theory – can interact with the Spore Drive in the same way as Stamets means his unique usefulness is at an end.

So the question is this: was Stamets’ unique ability stripped away from him for a reason? Could Season 3 have been setting up a situation in the near future where the crew will have to survive without him? Or was it just a natural progression in the story of the Emerald Chain’s takeover of Discovery? Actually I guess that was three questions! But the point stands: Stamets is not the only one who can use the Spore Drive any more, and thus no longer feels anywhere near as safe as he did last season.

Character #4: Dr Hugh Culber
Status: Safe 💖

Dr Culber in Season 3.

Dr Culber has already been killed off once – and he didn’t stay dead! There was also a minor backlash in some quarters to the killing off of one of Star Trek’s first major gay characters. Sometimes LGBT+ characters can feel more “expendable” in films and on television than their non-LGBT+ counterparts; a trope that we could definitely do without!

LGBT+ issues aside, I feel that Dr Culber’s “back from the dead” storyline in Season 2 means he’s a safe bet to survive Season 4. It would be a stupidly complicated storyline to kill him off for the second time, and I think for production-side reasons the writers and producers are less willing to kill off Dr Culber than almost anyone else.

Character #5: Sylvia Tilly
Status: Probably Safe 💖

Tilly in the second Season 4 trailer.

I’m calling Tilly safe because it just doesn’t seem as though the writers and producers want to get rid of her yet. Tilly has been the one character other than Michael Burnham to have seen significant growth across all three seasons of the show, overcoming her anxieties to step up and even take command of the ship. The way she led a team of officers in the final couple of episodes of Season 3 came to embody that transformation – and her arc, while imperfectly executed, was nevertheless powerful to see.

As Tilly is still young and only a junior officer, there’s plenty of room to continue that growth. I don’t think she’s going to be Captain Burnham’s first officer in Season 4, but it could well be that her arc across Season 4 and perhaps into Season 5 is readying her to take on that role again. Regardless, I don’t expect to see her killed off in Season 4.

Character #6: Cleveland Booker
Status: Safe 💖

Book in the second Season 4 trailer.

Unless Discovery plans to introduce a new main character, Book is the show’s main guide to the 32nd Century. Not only does he serve in that role for Captain Burnham and the crew of the ship, but he’s also a great character to show us as the audience the perspective of a 32nd Century native. He has a major role in that regard, and unless he can be replaced with a like-for-like character I can’t see the show dispensing with him.

Booker also has a relationship with Captain Burnham to consider, and while we can expect some bumps in the road with that perhaps, I think killing him off at this stage would be too much for Burnham after everything else she’s been through. I’d like to see Book help to anchor Burnham and keep her grounded as she handles the burden of command – serving as a confidante and her closest ally. Book’s story is also incomplete, and we’ve been promised a closer look at his background in the future. For all of those reasons and more, I think he’s pretty safe!

Character #7: Admiral Charles Vance
Status: In Danger ☠️

Admiral Vance in Season 3.

I felt Vance was in danger toward the end of Season 3 as well, and that he could’ve fallen victim to the Emerald Chain when they attacked Federation HQ. That didn’t happen – fortunately – but Admiral Vance definitely feels in danger as we approach Season 4. As one of the most significant secondary characters in Season 3, Vance’s death would carry more weight than a lot of other secondary characters’ would, which is one reason I felt he might’ve been in danger last time around.

Two things struck me from the Season 4 trailers: the almost total absence of Vance and the arrival of Federation President Rillak. Rillak, as I’ve noted in the past, seems to occupy a similar role to Vance’s in Season 3, serving as a “big boss” for Captain Burnham and the crew to ultimately be answerable to. That was the job Vance had as head of Starfleet in Season 3, but if Burnham is now reporting directly to President Rillak… what is there for Vance to do? Combine that with his absence from the two trailers and I wonder what might’ve become of the head of Starfleet.

Character #8: President Rillak
Status: In Danger ☠️

President Rillak in the second Season 4 trailer.

President Rillak’s status is difficult to gauge because she’s brand-new! We’ve only seen her in action very briefly in the trailers for Season 4, so what role she might ultimately play is unclear at best. However, there are a few reasons to think that she could be in danger.

Firstly, any new character should automatically be assumed to be in danger! It’s easier to kill off a brand-new character than an established fan-favourite, and doing so could be a relatively easy way to communicate the stakes in any story. Secondly is Rillak’s role: President of the Federation. The death of someone in such a powerful position is always going to have a significant effect, even if we as the audience didn’t know her particularly well. Thirdly, the main scene we’ve seen so far featuring President Rillak showed her facing off against Captain Burnham in at least a semi-antagonistic way. Killing off a character who’s either a villain or a hurdle to our heroes is a trope as old as time!

Characters #9 and #10: Adira Tal and Gray Tal
Status: Safe 💖

Gray and Adira in Season 3.

One storyline in Season 4 is going to focus on Gray’s quest to be “seen” – to become corporeal again somehow. Discovery certainly won’t kill off Adira and Gray without bringing this story to its conclusion, as it’s an incredibly powerful analogy for the status of trans and non-binary people – as well as being an exciting and interesting story in its own right.

Gray is tied to Adira, and thus it isn’t possible to kill them off without also killing off Gray. I think that makes both of them safe, though there is a lingering question as to what exactly Gray is. Star Trek doesn’t do ghosts, so Gray has to be explained scientifically somehow! Regardless, both characters feel assuredly safe.

Character #11: Dr Tracy Pollard
Status: In Danger ☠️

Dr Pollard at the beginning of Season 3.

After three seasons we don’t really know Dr Pollard very well. She’s often been seen in sickbay, and has patched up many of our heroes when they were injured, but aside from being a competent doctor we don’t really know very much about her. She appeared a few times in Season 3, but was never front-and-centre even in sequences in sickbay.

Dr Pollard is one of those secondary characters who has been in the background for the show’s entire run. Killing her off would be an easy option for Discovery in many ways; an attempt to get the impact of the death of a familar face without having to kill off anyone major. Be on the lookout for an Airiam-style spotlight on Dr Pollard – if she suddenly becomes the focus of a major storyline, she could be on her way to the chopping block!

Character #12: Kovich
Status: Safe… for now! 💖

Kovich in Season 3.

Until we know who Kovich is and what his role is in the hierarchy of the Federation, I can’t imagine Discovery would kill him off. There’s too much mystery surrounding this character, and to leave that unresolved would be fundamentally frustrating at a narrative level. My personal theory is that Kovich is the head of Section 31, or perhaps Starfleet Intelligence, but none of that has been confirmed on screen yet.

Famed director David Cronenberg plays the character, and I think for both Star Trek and Cronenberg it’s been a great partnership. Kovich thus feels safer than most, but it’s still possible that after we learn more about him and what his role has been that he could be killed off in future; he may not be permanently safe!

Character #13: Jett Reno
Status: In Danger ☠️

Reno in the second Season 4 trailer.

Tig Notaro, who plays Jett Reno, has said that the character won’t appear as frequently in Season 4 as originally intended. This is due to the impact of the pandemic on the show’s production. That doesn’t mean that Reno is necessarily in any danger, but it is worth noting.

Reno is famously sarcastic and deadpan, so her line in the second Season 4 trailer that she’s “lived a good life” could simply be her usual wit. However, it could also be some dark foreshadowing – and perhaps Season 4 could see Reno meet her end.

Character #14: Dr Gabrielle Burnham
Status: In Danger ☠️

Dr Burnham in Season 3.

It seems as though Dr Burnham and the Qowat Milat will have a significant role to play in Season 4 – at least based on what we saw in the second trailer. One thing came to mind when I saw other members of the Qowat Milat fighting and training, though: could they be seeking revenge for the death of one of their own? If so, perhaps Dr Burnham is the one who’s died.

This could be connected to the gravitational anomaly or it could be its own independent storyline. Regardless, Dr Burnham’s death would have a huge impact on Michael Burnham, and could be a major source of emotion and drama for her as the season rolls on. Coping with bereavement and learning to move forward while grieving are themes Star Trek has touched on in the past.

Character #15: T’Rina
Status: Probably Safe 💖

T’Rina in the second Season 4 trailer.

The President of Ni’Var, who we met in Season 3, would be an odd choice to kill off. It’s arguable that, if she does indeed lead Ni’Var back to Federation membership as the trailers have hinted, her story is complete and thus she may not have much more to do. But when considering character deaths, one factor is how their loss will impact others in the story.

Saru is the only main character with whom T’Rina has any significant relationship, and thus her death wouldn’t be as impactful for Captain Burnham and the rest of the crew even when compared to the new character of President Rillak. T’Rina being killed would still have the effect of communicating the stakes involved and the dangers of the anomaly, but it would matter far less from an emotional point of view. Thus I think there are probably better candidates when it comes to characters being killed off.

Character #16: Lieutenant Willa
Status: In Danger ☠️

Lieutenant Willa in Season 3.

Lieutenant Willa was Admiral Vance’s aide-de-camp in Season 3, and also briefly spent time aboard Discovery. She helped the crew acclimatise to the 32nd Century, and brought them up to speed on some of the new technologies that had been installed on the ship after arriving at Federation HQ. Though a good deal of Willa’s story and interactions with the crew happened off-screen, it’s fair to say she’s well-known to most of them and on friendly terms.

Willa’s death would thus have a significant impact on practically everyone aboard Discovery – especially if she had transferred aboard the ship or spent more time with Captain Burnham and the crew earlier in Season 4. Her death would also affect Admiral Vance – or she could even be a secondary casualty if Vance himself were killed. As a familiar face and someone known to the crew, Willa could be killed off to communicate the stakes involved in the story.

Character #17: Grudge
Status: She better be safe! Or else… 🐱

Grudge in the second Season 4 trailer.

Discovery can kill off a lot of characters… but the show better leave Grudge alone! Jokes aside, one of the best moments in the Season 3 finale was the way Book stood up to the villainous Zareh when he threatened to hurt Grudge. As a cat owner I love Grudge and I’m very protective of her… so if Discovery tried to get away with killing her off I might actually cry.

On a serious note, I think Grudge is probably safe. She gives Book’s character an extra dimension; a dependent for him to care for and look after. Plus she serves as a kind of mascot for the series. I can’t see Grudge being killed off in Season 4 – no matter how bad things get for Captain Burnham and Book!

Characters #18-23: The Secondary Bridge Crew
Status: In Danger ☠️

Tilly with several secondary characters in Season 3.

I’m lumping six characters together for this final entry because I found myself saying basically the same thing about all of them! Included in this group are the following: Detmer, Owosekun, Rhys, Bryce, Nilsson, and Linus. Most of them had an outing with Tilly at the end of Season 3 in which they were all in serious danger – most notably Owosekun. They all survived that encounter, but I’m not convinced they’ll all make it to the end of Season 4.

Detmer and Owosekun are the two characters we know best thanks to their development in Season 2 and particularly in Season 3. But any of these six could get the Airiam treatment and have a moment in the spotlight followed by a quick death. If Discovery wanted to show us the stakes and communicate the dangers involved without killing off a major character, any of these secondary characters could find themselves on the chopping block.

So that’s it. Those are my pre-season feelings about the safety of each of Discovery’s main characters!

Captain Burnham at the end of Season 3.

Season 4 is only three weeks away now, so we won’t have to wait too long to find out which of our favourite characters will survive the gravitational anomaly – and all of the other dangers out there in the 32nd Century! As I said at the beginning, I’m not advocating for any specific character to be killed off. I like everyone, even the secondary characters, and I wouldn’t necessarily want any of them to die.

At the same time, Season 3 felt like it had a little too perfect of an outcome for some characters, especially in the finale. Sometimes, when facing an impossibly dangerous situation, loss of life is inevitable. Making it so that characters continually survive the impossible quickly gets boring, and there was definitely a sense in the Season 3 finale that “plot armour” was protecting more than one character.

Owosekun is one of several characters who seemed to have plot armour in the Season 3 finale.

A well-timed and well-executed character death can be shocking, impactful, and emotional. When establishing the danger involved in a situation, seeing a character we know meet their end can raise the stakes dramatically for the remainder of the story, and the sense that anyone – even important named characters – could be in danger is part of what has made television storytelling since 2010 so entertaining and dramatic. Discovery doesn’t need to go down this road – but doing so could lead to some outstanding storylines and deeply emotional moments.

I’m looking forward to Season 4 now! Hopefully the show can build on the successes of Season 3 and continue the process of establishing the 32nd Century as a setting in its own right – while also telling a new and different story about the gravitational anomaly. It will also be great to see Captain Burnham in command of the ship in her own right for the first time. Let’s fly!

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