Star Trek: Discovery review – Season 4, Episode 13: Coming Home

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

I cried a lot while watching Coming Home. It was an incredibly emotional episode, one that hit all of the notes that it was aiming for and brought the season to a close in style. We can say definitively that Season 4 ended on a high, having saved the best for last. In fact, Coming Home might just be the best episode of the entire season!

From almost the first minute, the emotional punches started coming – and they didn’t let up until the epilogue. Captain Burnham and the entire crew went on a rollercoaster ride as they battled to stop Tarka, to get Unknown Species 10-C to listen, and to save Earth and Ni’Var from destruction. The episode was well-paced, with plenty of energy to keep things exciting but without ever feeling rushed. And there were some wonderful visual effects and animation work as we finally got an unobscured look at Unknown Species 10-C.

I had a wonderful time with Coming Home, and thinking about Season 4 as a whole, the finale is one of the strongest offerings. That contrasts with Season 3, where the end of the Burn’s story felt like a non-sequitur, if not an outright letdown. In that respect, it’s nice to see that Discovery has grown, adapted, and perhaps even taken on board some of the feedback received about the Burn and Season 3 in general. The creative team can be pleased, I think, that they did a better job this time around.

All that being said, there are some issues that are raised by Coming Home. The episode itself was great, and even some of the storylines that I’d been less invested in were paid off in emotional style. But thinking about the episode as the concluding chapter of a thirteen-episode season, I do have some complaints about absences, about characters who weren’t well-used, and about specific storylines that didn’t get the kind of payoff I’d been hoping for. While these points don’t detract from a wonderful and emotional episode in Coming Home, they do count against Season 4 as a whole.

Dr Hirai was a character with potential who felt sadly underused this season.

In the weeks ahead I’d like to do a retrospective of the season, and when I do I’ll go into more detail about some of these complaints. But with Coming Home being the season finale, I’d be remiss not to mention them here. This was the last chance for Discovery to do something significant with some of these narrative points – especially when considering that Season 5 will almost certainly go in a different direction.

Ruon Tarka’s abrupt turnaround from an understandable and even sympathetic character to a bold-faced villain was not handled particularly well, and while Coming Home went some way toward reversing that and bringing back some of the nuance that had made him such an interesting character in the first place, it came too late. Tarka’s story – much like Tarka himself in his final moments – ran out of road, and ended in an unspectacular and unsatisfying fashion, with no real payoff to his quest to reach Oros and Kayalise.

Tarka met his end in an unsatisfying way.

The scenes between Tarka and Book were beautifully constructed, and the raw emotion that both David Ajala and Shawn Doyle brought to screen is undeniable. The performances were fantastic, and Coming Home found enough time to show off these moments despite having plenty of other narrative beats to get through.

Despite that, however, the damage to Tarka’s characterisation had already been done. The complex and nuanced character that we met in The Examples, half a season ago, had been developed slowly over several episodes. His desire to use the power source at the heart of the DMA was explained through a series of flashbacks that introduced us to his long-lost friend Oros… and it feels like none of that really went anywhere. There were the ongoing themes of grief and loss that have been running since Season 3, and I guess we could argue that Tarka represents a different kind of reaction to those things than other characters. But even then, this side of the story doesn’t feel particularly strong.

It was nice to see that, in his final moments, Tarka seemed to come around to Book’s way of thinking. As he stood on the wrecked bridge of Book’s ship, awaiting the inevitable, he’d taken several steps back toward being the complex character that we believed him to be in his earlier appearances, and I do appreciate that. It wasn’t that there wasn’t time to pay off Tarka’s well-established story. It’s just that Discovery chose not to.

This was a story that, at the end of the day, didn’t need Tarka. It didn’t need a villain to be outsmarted and killed in the final act; all the pieces were in place for a story of first contact with Unknown Species 10-C that was tense, interesting, and engaging without him. There was more than enough drama and excitement in that premise to make Tarka’s addition unnecessary; fluff to pad out a season-long story that I’m sure I’m not alone in feeling had been padded out far more than it should’ve been.

Tarka was ultimately the villain of the season… but he didn’t need to be.

Season 4 could have been structured differently, with the Tarka and Unknown Species 10-C stories going in different directions. If one story had concluded around the time of the mid-season break, the second half of the season could’ve followed another related but separate story… and when both sides of the story were overstretched by running for as many episodes as they did, perhaps that would’ve been preferable.

But that’s less about Coming Home than it is about the structure of the season as a whole! Despite my waning interest in the Book and Tarka story, Coming Home pulled out a complex and emotional ending for both characters. It wasn’t the way I would’ve necessarily hoped for nor chosen, but once the decision had been made to kill off Tarka in this way and to have the fake-out over Book’s death, Discovery executed it about as well as possible.

Tarka and Book caught in an explosion.

Going into the finale there were genuine concerns for Book and Reno’s survival. While a fifth season has been confirmed, neither character was guaranteed to appear in it, and there was a real possibility that one or both could’ve died as Tarka tried to execute an increasingly desperate (and, sadly, an increasingly nonsensical) plan. When it came to the moment of Book’s apparent death, it thus felt like he was really gone; there was no part of me saying “this is all just a fake-out.” And again, this was one of many emotional punches that Coming Home set up and delivered perfectly.

Book’s survival was also kept hidden by the story – we weren’t immediately shown him alive with Unknown Species 10-C – which kept things going as other storylines played out. As a fake-out, I think it worked pretty well. It made Book’s return in a pillar of light feel genuinely wonderful, and took Captain Burnham on a rollercoaster that allowed Sonequa Martin-Green to really show off her emotional range. Both as a story point and on the technical side of things, it worked well for Coming Home.

Book was saved by Unknown Species 10-C.

But, as I’ve found myself saying numerous times as the season has worn on, it means that Discovery has yet again given all of its characters some pretty serious plot armour. In an individual episode we can forgive that a near-death situation resulted in survival, or that an apparently-dead character like Book was safe all along. But when we consider the season overall, no one aside from Tarka was actually killed. Despite the incredibly dangerous situations that the crew found themselves in, and despite the overwhelming odds stacked against them by Unknown Species 10-C, the DMA, Tarka, and everything else they went through, they all survived.

Television storytelling has moved on since Star Trek’s early days – something that the very nature of Discovery is itself testament to. To run an entire season this way – with another “galaxy-ending” calamity for the crew to deal with, which they all survive – risks diminishing the threat felt in future stories. If we as the audience can feel confident that everyone will be fine, no matter what else is happening or how badly the ship seems to be blowing up, that robs the show of a significant portion of the excitement, tension, and drama that its storylines have done an otherwise good job at creating. Book’s fake-out “death” isn’t the problem in and of itself; it’s a symptom of a much bigger issue – the obvious lack of willingness on the part of Discovery’s writers to allow even the most minor of tertiary characters to be killed off. In 2022 that’s out-of-date, and it’s a storytelling mistake that will have to be addressed in future.

Book survived… and so did everyone else.

The whole “Earth is in danger” angle is a trope that I wish hadn’t been brought into the story this season. It’s such a played-out cliché, and it’s one which, as I noted a couple of episodes ago when it was introduced, risks making the end of the story feel formulaic. It was obvious two episodes back that Discovery wasn’t going to allow the destruction of Earth and Ni’Var in the final act of Season 4, so unfortunately I went into Coming Home with that expectation firmly embedded in my mind.

That doesn’t mean that the route to saving Earth was easy, and on the Federation HQ side of the story with Tilly and Admiral Vance there were some absolutely wonderful moments. The swooping arrival of the USS Mitchell – named for Discovery actor Kenneth Mitchell – hit all of the right notes for me, echoing moments like the Enterprise-E’s dramatic entrance during the Battle of Sector 001 in First Contact. In fact, all of the evacuation sequences worked well, and after her departure earlier in the season it was nice to welcome back Tilly – however briefly.

The USS Mitchell arrived to save the day!

I’d have liked to have seen something earlier in the season to perhaps set up some kind of dynamic between Vance and Tilly, and that would really be my only criticism. The two didn’t feel like they had natural chemistry; I was acutely aware of the difference in status between the head of Starfleet and a character who, until a few episodes ago, was a lowly ensign. The two performers did well to sell it, but had we seen Tilly offered her role at Starfleet Academy by Vance, not Kovich, back in All Is Possible, I think we would’ve had some kind of baseline for their relationship. This would’ve let us see how far they’d come to be able to sit together and share a drink as they awaited what seemed to be the inevitable.

That said, I liked the evacuation sequences. In fact, this part of Coming Home might actually be my favourite – surpassing the meeting with Unknown Species 10-C, and definitely beating out the conclusion to Tarka’s story. There’s something about a doomed, heroic “last stand” that always gets me no matter how it’s played, and for Vance and Tilly, they knew that they didn’t have any control over the DMA situation. They had to do their jobs knowing there was nothing they could do to prevent what was happening – they were relying entirely on Captain Burnham and the USS Discovery.

Admiral Vance led the evacuation efforts.

That setup led to a real unexpected highlight. I maintain it would still have worked were it not Earth in the firing line, but setting aside that particular narrative gripe, the scenes at Federation Headquarters were pitch-perfect. Seeing Federation HQ warp in to offer to help, even though Earth was not a member of the Federation, really epitomises what the Federation is all about. That is the spirit of Star Trek, in many ways: offering to help while asking nothing in return. The DMA placed Earth in danger, and Starfleet rode in to help without even having to think twice.

Admiral Vance and Tilly both came to embody that Federation spirit in these sequences, and they gave it their all to get as many people to safety as they possibly could. Choosing to remain behind to cover the escape of the final ships was just the perfect end for both of them – and something I could absolutely see both of them being willing to do. As they sat down, knowing they’d given their all, and shared a drink, I was absolutely blown away by this unexpected and wonderful addition to Coming Home.

We also got to spend a little more time with some of Tilly’s cadets from All Is Possible. After those characters fell somewhat flat in that story, it seems like at least some of them have grown into their roles as Starfleet cadets, which was nice to see. It wasn’t a huge part of this side of the story, but it was a neat way to include something that had been established earlier in the season.

There was, unfortunately, a gaping hole on this side of the story. It wasn’t really apparent until Coming Home was drawing to a close, and it didn’t detract from the way any of these incredibly emotional moments felt as they unfolded. But in retrospect I have to ask: where was Dr Kovich? Is he just a gag character now, someone whose lines tease stories that sound interesting but go nowhere? Because that’s what it feels like. After Dr Kovich’s line in The Galactic Barrier that he had “more important things” to do than make first contact with the species who built the DMA, I was hoping that Discovery would pay that off somehow… but it didn’t happen.

What happened to Dr Kovich?

We’ll deal more with the Dr Kovich situation when I take a look back at the season as a whole, but suffice to say that his absence from this part of the story was noticeable, and several threads that seemed to tease that he was working on something interesting with Lieutenant Commander Bryce ultimately just went nowhere. This isn’t a situation like the Picard Season 1 finale, either, where the meandering story of the season ran out of road and didn’t have enough time to pay off its stories… this was a conscious choice on the part of Discovery’s writers. They teased us with Dr Kovich all season long, feeding us little crumbs of information that seemed to set up something about his character… and then just dropped it, perhaps with a snide laugh behind their hands, in the finale.

As the episode wrapped up, it seemed as though Discovery had one last surprise up its sleeve. As the President of United Earth was about to arrive, I wondered if we might be about to see Dr Kovich when the doors wooshed open – if not, perhaps a character from a past iteration of the series. When it was revealed to be a new character I wasn’t disappointed; it seemed as if the point the series was making with the buildup to her reveal was that the President of the Federation, the President of United Earth, and the Captain of Discovery are all women, which I thought was a neat way to go.

I had no idea who this was at first!

But there was more to it that, as a non-American, I missed at first! The President of United Earth was played by Stacey Abrams, an American politician and writer who’s been quite politically active on the left wing of US politics. This casting choice is interesting – and perhaps a little provocative! There will be people on the conservative side of things who will feel upset, and Discovery knew this well in advance of casting this character. Doing so was a way for the series to really emphasise its progressive principles, which have been front-and-centre just as they’ve always been in Star Trek.

Star Trek is no stranger to cameos and stunt castings, before anyone jumps in to say that this one is somehow different because of who it is. The King of Jordan had a cameo in Voyager once upon a time, and there have been real-life astronauts, scientists, and other celebrities who’ve all joined in for guest-starring roles. Considering that Stacey Abrams is, as far as I’m aware anyway, a newbie to acting, I think she did a wonderful job!

The President and the President shake hands.

I adored this scene with the President of United Earth. Set aside the casting for a moment, because the content of the scene made a huge impact on me. Coming Home had already been a hugely emotional story, so seeing Earth rejoin the Federation after two seasons outside it was pitch-perfect. Stacey Abrams and Sonequa Martin-Green excelled in their moments together, and what resulted was an optimistic and emotional high to bring the episode – and the season – to a conclusion.

There are some interesting real-world parallels that the casting of someone like Stacey Abrams arguably hammers home. After the United States had pursued a nativist, isolationist policy for four years, the country is stepping away from that. United Earth rejoining the Federation could be viewed as symbolic of America’s return to the world stage. From a British perspective, it could be seen as a hope for the UK one day rejoining the European Union after the Brexit referendum. Star Trek has always used its sci-fi setting to look at real-world issues, and those are just a couple of possible ways we can interpret this emotional and uplifting end to the season.

We’ve come all this way but we still haven’t talked about Unknown Species 10-C! The visual effects used to create one of the most “alien” races ever seen on screen in Star Trek were excellent, though I would caveat that by saying that the meeting place being a carbon copy of the ruin visited in Rosetta detracted a little from the way things looked. Recycling sets has been something that the Star Trek franchise has always done, but this moment was the crux of a season-long story, and I think more could’ve been done to give Unknown Species 10-C’s new home a new look, even if it was just in a minor way through changes and tweaks. It’s been a millennium since they lived on the planet seen in Rosetta, so if for no other reason than the passage of time we might’ve expected it to look slightly different.

That being said, I liked Unknown Species 10-C both in appearance and in concept. Star Trek has a long history of showing us alien races that look only slightly different to humans – and in some cases are completely identical! That’s never been a problem for me; I think it’s part of the suspension of disbelief that one has to have when stepping into the Star Trek galaxy. However, the rise of modern CGI and animation, combined with new technologies like Discovery’s AR wall, mean that some very different aliens can be created and can be blended with real actors. This blend was seamless in Coming Home – as it has been, with only a few exceptions, all season long.

The story of bridging a communication divide is honestly one that I could’ve spent longer on. Much of the legwork had been done in Species Ten-C last week, so we got less of the minutiae that a “learning to understand one another” story can provide. But what we did get was interesting, and we got to see how Unknown Species 10-C didn’t mean to do anything wrong – their scans didn’t indicate that there were sentient life-forms in the areas that the DMA hit.

In that sense, we have a comparable situation to the Burn in Season 3. Unknown Species 10-C weren’t some horrible invading alien for Starfleet to heroically defeat; what happened was a genuine accident, one that they regret. That may not be enough for someone like Book, who lost his home, his family, and his entire race… but it’s a different ending, one that many other sci-fi franchises wouldn’t have even considered. Discovery pulled it off, and while the story leading up to it was imperfect and padded, it worked.

However, Discovery has now run four seasons with some variation of the “major galactic threat” storyline, and I think that framework needs a break. Not every story has to be about the entire galaxy, Earth, and the whole Federation being in danger – there can be just as much drama, tension, excitement, and emotion from stories that are smaller in scale. Just because a story doesn’t threaten life as we know it doesn’t mean it doesn’t matter, and how we as the audience respond to a story begins with the way the characters we’re invested in respond to it. So consider this a plea to all of Discovery’s writers and producers: try something different in Season 5!

I enjoyed the performance from Chelah Horsdal as President Rillak. For practically the whole season I couldn’t tell if we were going to get a “bad Admiral” type of character turn; President Rillak certainly seemed to have a Machiavellian edge that could have made for a wonderfully complex antagonist. In Coming Home, though, we got to see the culmination of her diplomatic efforts and her leadership of the Federation, both through the way the DMA threat came to an end and through Earth rejoining the organisation – something that had been one of her major objectives.

For what feels like the first time this season, Stamets had more than just a couple of lines. It was a shame that he couldn’t be present at the meeting with Unknown Species 10-C; I’d have rather seen him there with Dr Culber and Adira to stand alongside Captain Burnham than some of the secondary bridge characters, really. But it was still nice to see Stamets and his family coming together at the climax of the story, and how Dr Culber forfeited his own chance to go on the away mission to be with them.

Stamets and Culber formed Discovery’s emotional core in the first season and the third, with a disappointing foray into a relationship squabble in the second. But aside from a few smaller scenes, neither character really seemed to have all that much to do in Season 4. With Gray’s story brought to a conclusion early on, in the episode Choose To Live, the family dynamic changed, but Stamets missed practically all of that. In fact, his only scene with Gray all season that I can recall was when Gray left to return to Trill. In short, I was glad to welcome back Stamets in Coming Home, and thrilled to see him bonding again with Culber and Adira… but the reason why it felt so great is because I’m aware of how absent moments like that had been all season long.

Adira, Dr Culber, and Stamets.

I was not a big fan of the Burnham-versus-Book relationship drama angle that began in But To Connect earlier in the season. It didn’t work for me, and I felt that the focus on Burnham and Book’s emotions, particularly in episodes like All In and Rubicon, came at the expense of other characters and other story developments. It was cathartic, then, to see the two finally reconcile in Coming Home, and I’m glad that the season didn’t end with their relationship left in question.

Because of the timing of Book’s fake-out “death,” it could have ended there and still felt satisfactory; Captain Burnham would’ve known that Book loved her, and his actions in his final moments would’ve been trying to stop Tarka and prevent an escalation of the damage he’d already done. That could’ve worked – but I’m glad that Book lives to fight another day and that they got to have a proper sit-down together and a proper reunion on Unknown Species 10-C’s planet. After a storyline that shook things up too much for my taste, a proper resolution that has hopefully set the stage for a rock-solid relationship between them in Season 5 was the least bad outcome.

Captain Burnham and Book embrace.

I enjoyed the speeches both Captain Burnham and Book gave to Unknown Species 10-C, and it was great that they were able to find a way to connect with a species that could have been “too different” to bridge the divide. Book’s speech after his resurrection was remarkable, and the emotion packed into each and every word resonated. David Ajala has done a great job all season long conveying Book’s grief and sense of loss, and he brought everything to bear in this scene as he came face-to-face with the race who killed his family and destroyed his home. It was heart-wrenching to watch.

Captain Burnham’s speech was likewise packed with emotion, particularly as she was still reeling from the shock of Book’s apparent death. This was definitely one of Sonequa Martin-Green’s best moments of the season, as Captain Burnham finally made contact with the enigmatic race. She had to convince them that they needed to stand down – and with just moments remaining, she was able to do so.

Captain Burnham spoke to Unknown Species 10-C.

General Ndoye, who had been responsible for Tarka’s escape during the events of the previous episode, stepped up and admitted what she had done. She presented a strength of character that I wasn’t expecting given how she’d been roped into Tarka and Book’s conspiracy. The idea that the first contact mission was progressing but was sabotaged by people who were unwilling to wait was an angle that was potentially interesting – but it didn’t need to go to such extremes, perhaps.

Still, I liked General Ndoye. Phumzile Sitole played the character with a kind of hard-nosed pragmatism, and although General Ndoye was in the wrong from Captain Burnham’s point of view, it’s only because we as the audience could see what was happening that we realised that. Ndoye acted in what she believed to be Earth’s best interests based on the information she had available – she was never a villain nor an antagonist, and she remained in that complex space even while Tarka was being transformed into an out-and-out villain last week.

A few scattered thoughts before we wrap things up:

  • Coming Home contained the first mention of the Borg in Discovery… could that be setting up something to come in Season 5, or perhaps some kind of tie-in with Picard? I can’t help but wonder! Seeing Captain Burnham go toe-to-toe with the Borg would be delicious!
  • Dr Hirai felt sidelined once again, contributing relatively little to the story. This character feels like a waste of potential – someone interesting whose role on the mission made sense, but who was underused and who underwhelmed in the few appearances he made.
  • The destruction of Book’s ship feels like it could be symbolic… but I’m struggling to find the intended symbolism considering that Discovery will presumably bring him back in Season 5, and the show didn’t exactly go through a soft reboot at the end of the season.
  • Unknown Species 10-C definitely gave me a “sea monster” vibe.
  • It was so sweet that Saru and T’Rina finally got together!
A happy ending for T’Rina and Saru!
  • Shutting down the hyperfield, which Unknown Species 10-C had been running for a millennium, seemed a bit quick right at the end.
  • It would’ve been interesting to see Captain Burnham having to lead Discovery on a Voyager-esque mission back to Earth… but Unknown Species 10-C’s wormhole tech meant it never felt like a realistic prospect.
  • I will always love seeing Admiral Vance with his family!
  • The use of Grudge’s collar to escape the forcefield was a clever inclusion that felt like classic Star Trek technobabble.
  • I hope we’ll see Unknown Species 10-C again and they won’t just be forgotten about in future 32nd Century stories.
  • Will Federation HQ now remain permanently in orbit of Earth? Or will other planets want to have Federation facilities, given that Earth has been absent for more than a century? It could be interesting to explore such a conflict in Season 5.

There’s a lot more to say, quite honestly… but I feel this is already running long. It’s taken me a long time – longer than usual – to get my thoughts in order, and I find that a lot of what I want to say in a more critical way is more about the story or structure of the season as a whole rather than about Coming Home specifically. It was a great episode in its own right, it capped off the season in a beautiful, emotional way, and left me with a real sense of optimism as Discovery prepares for a fifth season. But despite a solid ending, Season 4 as a whole is much more of a mixed bag, and I’d like to talk about that more on another occasion.

Coming Home was the emotional high point of an occasionally frustrating season, but it’s an episode that means we can say that things ended on a positive note. I’m genuinely excited for Season 5 and to see where the show goes next… but I hope it’s not going to be another “the galaxy is in danger” storyline! After the Klingon war, Control, the Burn, and the DMA, we’ve had enough of those.

It took me a while to get this review together, partly because of how much of an emotional experience Coming Home was… and partly because I’m feeling a little burnt out after three weeks of two Star Trek episodes meaning I was writing two big reviews! I really wish Paramount Global would sort out its scheduling…

Star Trek: Discovery Season 4 is available to stream now on Paramount+ in the United States, Scandinavia, Latin America, and Australia. Individual episodes or the full season can be purchased on iTunes, Amazon Video, Google Play, and possibly other platforms in the UK, parts of Europe, and select other countries.

Star Trek: Discovery review – Season 4, Episode 12: Species Ten-C

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

Species Ten-C wasn’t just a good episode in its own right, with plenty of excitement and tension that showed how Star Trek can do a heck of a lot without resorting to violence and battles, but it was one that made the episode immediately preceding it significantly better in retrospect. I wrote last week that the one saving grace to an otherwise frustrating experience in Rosetta could be if the hydrocarbons discovered by Captain Burnham and the away team were put to good use – and that happened in a big way this time.

On the other side of the story, I finally felt what I believe the writers have been aiming for for weeks with the Book and Tarka storyline: that Captain Burnham was right, diplomatic initiatives should be given a chance, and that Book has fallen victim to Tarka’s manipulations. While this has the unfortunate effect of relegating Tarka from a complex character with an equally understandable motivation into the out-and-out villain of the season’s final couple of episodes, it clarifies what had been until now a very fuzzy and occasionally frustrating story.

The Book and Tarka storyline was expanded upon in a big way this week.

If I were to be critical of Species Ten-C, what I’d say is that it probably took too long for the season to reach this point. Several advances in the DMA/Unknown Species 10-C storyline were sprinkled in at or near the end of unrelated or tangentially-related episodes, with the Federation often running into problems or delays that took too long to surmount, and the result of that is that it took a long time to arrive at the hyperfield.

The story of finding a way to bridge the communication divide could have been a longer one, and it was handled in a genuinely interesting way – but with only half an episode dedicated to it here and just one final episode of the season remaining, it’s an interesting concept that may not be explored in as much detail as it could have been.

Species Ten-C saw the crew making first contact.

This story of learning how to communicate with someone far more alien than usual, and doing so while under threat thanks to the DMA, is not one that required a B-plot villain. While Tarka was interesting in his earlier appearances and his motivations were laid out in a clearly understandable way, the narrative just doesn’t require this additional element in order to be exciting.

Discovery has a tendency, as I’ve pointed out on a number of previous occasions, to try to inject double the tension and three times the drama when it just isn’t necessary, and if I were to make one comment about the series as a whole it’s that the writers need to have more confidence in their stories. Dropping the Tarka angle, or reworking it to make him less of an antagonist in this final chapter, would allow the main story of learning to communicate with Unknown Species 10-C to stand on its own – and as it’s already sufficiently tense, interesting, and engaging, Tarka’s villainy just isn’t necessary.

Tarka in Species Ten-C.

Not for the first time, Discovery has set up a character who feels well-rounded and complex, with motivations that seem understandable, only to turn them into a pretty standard villain later on. I wouldn’t have even called Tarka “morally ambiguous;” his weapon plan made a lot of sense when it was first proposed, and I even suggested that a show which has had themes of seeking a “middle ground” could have figured out a way to keep Tarka on board, building his weapon as a back-up plan while attempting to make first contact. But as with Captain Lorca in Season 1, much of Tarka’s nuance now feels lost; brushed aside because the writers determined that the season needs a villain.

There were other ways to formulate this story that either skipped over Tarka altogether or that kept him in that complex space. We may yet learn that his interdimensional transporter will be important, in which case he may have served a narrative function, but if the ending of the story is going to be Tarka’s defeat or death, with a reunion with Oros not being able to happen, then I think I’ll have to go back and re-evaluate his role in the season overall. This story already had the complexities of Unknown Species 10-C and the DMA; I’m not sure it needed a second antagonist, especially not one who seems to have come at the expense of an interesting and complex character.

Tarka with Oros earlier in the season.

We’ve also got to talk about the new character of Dr Hirai. In short, he needs to do something truly outstanding and unique next week – otherwise his inclusion in the season will have proven to be a complete and utter waste of a great actor. I like the concept of the character; a linguistics and communications expert seems perfect for this kind of mission. But in his two earlier appearances this season he did nothing whatsoever, and his accomplishments this week were relatively minor. It didn’t feel like bringing Dr Hirai along was in any way important to the success of the mission, with Captain Burnham, Zora, Saru, and even characters like Detmer, Nilsson and the very minor Lieutenant Christopher all contributing at least as much – if not more – to the story as he did.

He was ultimately sidelined by President Rillak, who chose Saru and Burnham over him for their linguistics and first contact expertise, confirming his relegation to a bit-part role at best. In light of what happened last week with Rosetta, I’m willing to wait and see if Dr Hirai will yet make a significant contribution – but with only one episode left in which to do so, he needs to do something big pretty quickly or we’ll unfortunately have to consider his inclusion in the story a bit of a let-down.

Dr Hirai doesn’t have long left to make an impact on the story.

There is one concept underlying the way Unknown Species 10-C reacted to Discovery’s arrival – and the conversation it prompted between Captain Burnham and the others – that I didn’t like. As humans, we’re able to recognise signs of intelligence in other species, even though we’re far more advanced and intelligent than they are. We can recognise the complex social structures present in ant colonies, for example, or how crows and some great apes are learning to use tools. Even though these creatures are far lower on the intelligence scale than we are, we’re able to determine quite easily that animals – even small and lowly ones – can exhibit signs of complex understanding and intelligence.

With that in mind, the idea that Unknown Species 10-C would see a starship arriving at warp speed, using a warp core and a spore drive, built from clearly artificial alloys, and somehow not understand that the creatures aboard it are sentient makes no sense. This species is supposedly much farther advanced than even the 32nd Century Federation, and even though they exist outside of the galaxy they must have the ability to scan and detect the existence of other sentient species, even if they choose not to interact with them. It’s conceivable that they might be selfish and not care about any other species besides themselves – but the idea that they would be unaware or incapable of determining intelligence in this situation is one that I can’t buy as a believable story point.

The USS Discovery approaches the hyperfield.

It seemed at first as though Species Ten-C was going to centre on this aspect of first contact, and I was certainly a little disappointed at first. But thankfully this didn’t last too long, with Unknown Species 10-C eventually getting the message and realising that the life-forms aboard the warp-capable starship are actually intelligent. Took them long enough!

I know that probably sounds like a nitpick – and it is, in a way. It’s just that, despite all of the talk of Unknown Species 10-C being very alien and having a very different culture, some things should be universally obvious – like if someone is capable of building a starship that can travel faster than the speed of light, use metal alloys that don’t exist in nature, and fly right up to your base to initiate contact, it’s probably a safe bet to assume that they possess some degree of intelligence. That should apply no matter who you are! And as pointed out above, humans are capable of recognising the signs of intelligence in the natural world. As a narrative beat, I get that it was in there to make the initial meeting feel very tense, but it’s kind of illogical if you think about it!

A representative of Unknown Species 10-C.

We didn’t get a clear look at Unknown Species 10-C, as their representative was partially obscured by a cloud of swirling gas. Nevertheless, the visual effects on this side of the story were mostly high-quality, and Unknown Species 10-C themselves at least seem like they’ll be visually interesting if we ever get a better look at them. I actually got a slight “Mass Effect Leviathan” vibe from what we glimpsed of Unknown Species 10-C. The design of the hyperfield was likewise interesting; it appeared much more solid than I had been expecting based on the holographic projections seen in previous episodes. Seeing it go from solid-metallic looking to swirling like fluid was also a very cool visual effect that Discovery executed well.

The only visual that I felt was a bit of a miss was Unknown Species 10-C’s shuttle pod/diplomatic chamber. When it arrived in Discovery’s shuttlebay it looked rather bland and low-quality, like a video game where a texture hasn’t loaded properly. It was clearly designed to look similar to the hyperfield, but I guess trying to blend that with a real set and real actors was difficult. It didn’t look awful, but it was noticeably lower quality when compared to the rest of the visual effects and animation work present in Species Ten-C.

This visual effect felt rather weak.

The idea of Unknown Species 10-C recreating part of Discovery as an environment for the crew works as a story point – I can quite understand why they’d choose to do something like that. But I confess that I rolled my eyes a little when I saw Captain Burnham and the others stepping onto the bridge set. It was understandable in the context of the story, but it didn’t make for a particularly impressive or interesting sequence when shown on screen. In fact, it almost makes Species Ten-C feel like a “bottle” episode – a Star Trek trope going all the way back to The Original Series where episodes would be set entirely aboard the ship.

As mentioned above when discussing Dr Hirai, President Rillak chose to bring both Captain Burnham and Saru when boarding Unknown Species 10-C’s diplomatic shuttle. And aside from totally sidelining Dr Hirai, this also left the command structure of Discovery and the rest of the mission uncertain. Rhys had the ship’s conn, as we’d see on the bridge near the episode’s climax, but who was in charge of the remaining delegates and the rest of the diplomatic mission? And how far did Rhys’ authority extend? Would he, for example, have been authorised to fire upon Unknown Species 10-C if time began to run out for Earth? Taking both the captain and first officer on this mission – when other experts were available – is a bit of an odd choice, and while of course as the audience we want to see our familiar characters leading the charge, it again makes the addition of some of these other delegates and experts feel like a bit of a waste.

The interior of Unknown Species 10-C’s pod.

A longer episode – or a story which had arrived at the hyperfield earlier in the season – could have spent longer on the whole first contact thing, and I really think that would have been worth doing. I’m actually getting a bit of a familiar feeling the more I think about Species Ten-C: it reminds me of the finale of Picard Season 1 in the sense that the season dawdled a lot to get to this point, and it feels like there’s a lot of important story points left to get through with very little time remaining. As a result, some aren’t being given as much attention or screen time as they probably should receive. We aren’t at the same level as Et in Arcadia Ego – at least, not yet. But suffice to say that Season 4 as a whole has left its final episode with a lot of work to do to wrap up all of the major stories in a satisfying way.

There were a few very close-up shots of characters’ faces that made the cinematography in Species Ten-C feel a bit odd. Close-ups can work and can be dramatic, but their use here felt rather gratuitous, with the episode both beginning and ending with them in a way that made it feel like the director was throwing everything at the wall in an attempt to make things seem even more dramatic. As I’ve said on several occasions this season when discussing certain narrative choices, Discovery is already a series that brings plenty of drama to the table – trying to take it from a ten to an eleven can sometimes fall flat, and a few of these extreme close-ups definitely strayed very close to the line.

Was there any need for so many close-up shots?

Book saw some significant character development this week after several episodes in which he felt very static. Although Tarka’s motivation for continuing to pursue the DMA’s power source feels pretty well-established by this point in the story, I’ve been finding it increasingly difficult to reconcile Book’s presence on this side of the story in the aftermath of the failure of the isolytic weapon back in Rubicon. We hadn’t seen or heard enough from Book since that dramatic event to signal that he’s still on board with the next phase of Tarka’s plan – and this week he actually seems to have moved much closer to Burnham’s position.

Book’s cause is noble: he wants to stop the DMA from hurting anyone else in the way it destroyed his home and hurt him. And seen in that context, his decision to get on board with Tarka’s weapon plan was understandable. In Rubicon, Book indicated he would be willing to stand down for a short time to give diplomacy a chance to play out, and in the aftermath of the failure of the weapon, it wasn’t clear at all why he continued to follow Tarka. I’m still not exactly sure how he arrived at this point – was he motivated by fear of repercussions for the use of the weapon? Did he still believe it would be possible to destroy it after Tarka failed once? If so, is he now no longer willing to let Captain Burnham try for a diplomatic solution first?

Book in Species Ten-C.

These points were glossed over in Species Ten-C, but we finally got some movement from Book, arguably bringing him back into the fold as one of the “good guys.” It emerged that Tarka’s plan would destroy the DMA, destroy Earth, and destroy the hyperfield containing Unknown Species 10-C and the USS Discovery – so Book didn’t really have a choice! Again, this is Discovery pushing the story to extremes, and it feels as though Book coming back to the light is more of a necessity than a choice at this point. Still, it worked, and for the first time in several episodes I felt like I could relate to Book as a fully-rounded character again, not just a plot device caught up in the narrative wake of other characters with more volition.

There’s even a message in Book’s story, if we look a little deeper. The idea that grief can lead someone to a very dark place was already something we’d seen explored a little with Book earlier in the season, but now we can add into the mix themes of manipulation, of being lied to, and of getting involved with someone untrustworthy. It was initially grief that saw Book teaming up with Tarka, but he also had the noble objective of wanting to prevent others from having to experience that same level of grief. Unfortunately for Book, he relied on someone who turned out to be unworthy of his trust – and that’s how he ended up in this particular predicament.

Grief led Book down a dark path.

Reno saw her best scenes of the entire season on this side of the story, too. We’ll have to try to excuse the lousy “kidnapping” plot last week, because as weak and difficult to explain as that may have been, it ended up going somewhere significant. It didn’t necessarily have to be Reno as the one to reach out to Book – basically anyone on board the ship could’ve done so – but it was interesting to see her in this situation. Her words managed to reach him in a way that even Captain Burnham hadn’t been able to, and the sequences between the two of them worked exceptionally well.

Reno has often been used as a light-hearted character, bringing moments of deadpan comic relief that could lead to brighter moments in otherwise dark stories. This time, her role harkened back to her introduction in Season 2 – which was also referenced this week – when we first encountered her trapped aboard a crashed starship. A more serious performance from a comedic character carried a surprising amount of weight, and perhaps it’s because we know how Reno usually behaves and speaks that her words to Book meant a lot.

This was Reno’s best episode of the season.

For at least the past three episodes, Discovery seems to have been building up to a conclusion which is going to say something like: “if only Tarka and Book had told Captain Burnham what they were doing! It should have been possible for everyone to get what they want through diplomacy and communication!” and I don’t think that’s changed. It isn’t exactly formulaic, and there are still big questions about what Unknown Species 10-C will do and how Captain Burnham will respond to try to cool things down in the time that remains. But one way or another, the story’s going to get to that place.

As we approach the end of the season, feeling like we know roughly where the story is going to go was to be expected, I guess! And on its own merits, Species Ten-C was a good episode, one of the better offerings from Season 4 for certain. Whether it has moved things along far enough for the season finale to wrap up all of the remaining narrative threads is an open question, one we’ll have to wait until next week to get an answer for.

Book’s ship escaped the USS Discovery and entered the hyperfield.

Although I had some nitpicks within the story, overall I had a good time this week. Species Ten-C told a very “Star Trek” story, with perhaps some inspiration from the film Arrival in there too! Meeting a brand-new alien race and learning how to communicate is something truly interesting, and my biggest complaint is that I would have liked to have seen more of it – for the season to have reached this point a couple of episodes ago so we could have spent longer with Captain Burnham, Saru, President Rillak, and Dr Hirai as they worked on figuring out how to use a complex arrangement of lights and pheromones to communicate. It was nice to see some significant movement from Book, too, after several uninteresting or flat episodes on that side of the story.

Did Season 4 need to turn Tarka into a villain? I think that could be a question for a longer essay once the season has wrapped up! I could certainly entertain the argument that the Unknown Species 10-C story – one of misunderstanding, communication, and first contact – was strong enough to carry both this episode and the bulk of the season without requiring this kind of last-minute character twist. Between the DMA and the smaller character moments – some of which, as noted last week, haven’t been as thoroughly explored as they could have been – maybe it would have been better overall to find a different way to include Tarka. But we’ll talk about that more in the weeks ahead, perhaps.

For now, there’s only one episode remaining! This time next week it’ll be all over… or will it? Could a cliffhanger ending be on the cards?

Star Trek: Discovery theories – week 8

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

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

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

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

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

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

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

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

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

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

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

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

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

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

So those theories were confirmed and debunked.

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

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

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

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

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

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

Isolynium – a key component of Tarka’s weapon.

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

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

Tarka and Book.

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

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

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

R.I.P.

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

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

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

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

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

Theory #4:
Nhan works for Section 31.

Nhan.

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

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

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

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

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

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

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

Burnham and Book in All In.

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

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

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

“It’s alive!”
Frankenstein (1932)

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

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

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

Could it be the Borg?

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

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

How about Species 8472?

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

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

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

President Rillak, leader of the United Federation of Planets.

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

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

President Rillak with Captain Burnham on Ni’Var.

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

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

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

Captain Burnham.

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

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

Burnham in The Examples.

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

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

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

The Guardian of Forever as it originally appeared.

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

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

Theory #12:
Tarka will create his own DMA.

Tarka and Stamets with their DMA model.

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

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

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

Stamets, Tarka, and Saru with the DMA model.

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

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

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

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

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

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

So those theories are new or saw movement this week.

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

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

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

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

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

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

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

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

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

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

Star Trek has had some wonderful crossovers in the past.

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

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

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

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

Zora dancing with Craft in Calypso.

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

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

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

Spock’s funeral in The Wrath of Khan.

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

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

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

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

The dilithium planet is vital to the Federation.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Captain Burnham believes this image depicts a “supernova.”

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

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

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

Abronian stasis pods.

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

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

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

A deceased Abronian.

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

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

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

“That’s no moon…”

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

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

So that’s the main theory list.

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

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

Tilly’s departure feels permanent.

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

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

So that’s it!

Owosekun in the combat arena in All In.

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

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

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

Star Trek: Discovery theories – week 7

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

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

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

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

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

Dr Kovich.

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

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

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

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

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

Retired theory #2:
Zora will go rogue.

Zora with Captain Burnham in Stormy Weather.

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

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

Zora in But To Connect.

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

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

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

Kol, a 23rd Century Klingon leader.

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

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

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

Captain Burnham in But To Connect.

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

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

So those theories are done!

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

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

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

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

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

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

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

The USS Kelvin, namesake of the Kelvin timeline.

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

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

Kirk and Spock in the Kelvin timeline.

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

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

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

Tarka and Stamets made a model DMA.

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

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

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

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

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

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

Book and Burnham earlier in the season.

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

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

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

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

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

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

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

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

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

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

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

Theory #7:
Some areas of the galaxy – such as the Delta Quadrant – avoided the worst effects of the Burn.

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

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

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

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

Star Trek has had some wonderful crossovers in the past.

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

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

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

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

President Rillak.

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

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

President Rillak and Captain Burnham.

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

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

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

Theory #10:
Season 4 will connect with the Short Treks episode Calypso.

Zora dancing with Craft in Calypso.

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

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

So those theories are new or saw movement last week.

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

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

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

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

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

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

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

Shaxs’ funeral in Lower Decks.

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

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

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

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

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

Having reintroduced the Guardian of Forever in Season 3, I wouldn’t be at all surprised to see Discovery return to the Guardian’s planet in Season 4. Because Captain Burnham and the crew still don’t know much about the DMA or Unknown Species 10-C, it would make sense to at least ask the Guardian for help – maybe it has encountered this phenomenon or the people who made it before.

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

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

The dilithium planet is vital to the Federation.

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

It would begin to stretch credulity to think that everyone in the known galaxy would see the Federation rebuilding and having access to dilithium and not want to find out for themselves what’s going on. Once the Verubin Nebula’s existence becomes known, even if the Federation promises to share its bounty with all comers, it seems very likely that someone would want to take control of the dilithium supply for themselves. This could even be the objective Unknown Species 10-C have – they may be looking for a way to control the Verubin Nebula and its supply of dilithium.

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

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

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

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

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

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

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

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

Theory #17:
Michael Burnham won’t remain captain of Discovery.

Captain Burnham in The Examples.

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

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

Captain Burnham on the bridge in Stormy Weather.

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

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

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

Captain Saru.

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

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

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

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

In Star Trek: Generations, Captain Picard encountered Captain Kirk inside the Nexus – despite Kirk being declared “dead” after the Enterprise-B encountered the energy ribbon almost eighty years earlier. The DMA’s similarly mysterious nature raises the faint possibility that at least some of those it appears to have “killed” may not be as dead as they first appear.

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

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

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

Theory #20a:
The Abronians’ homeworld was destroyed by the DMA.

Captain Burnham believes this image depicts a “supernova.”

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

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

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

Abronian stasis pods.

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

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

Theory #20c:
The Abronians will return to help the Federation later in the season.

A deceased Abronian.

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

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

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

“That’s no moon…”

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

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

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

A Red Angel suit from Season 2.

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

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

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

Stamets, Tarka, and Saru with the DMA model.

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

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

The DMA.

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

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

So that’s the main theory list.

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

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

Tilly’s departure feels permanent.

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

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

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

Is a fifth season going to happen?

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

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

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

So that’s it.

Discovery will return in five weeks’ time.

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

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

Star Trek: Discovery Season 4 is currently on hiatus and will return on the 10th of February. The first half of Season 4 is available to stream now on Paramount+ in the United States, Scandinavia, Latin America, and Australia. The show is on Pluto TV in the UK, France, Germany, Italy, and other parts of Western Europe at 9pm on Fridays and Saturdays. Individual episodes or the full season can be purchased on iTunes, Amazon Video, YouTube, and possibly other platforms in the UK, parts of Europe, and select other countries. The Star Trek franchise – including Discovery and all other properties mentioned above – is the copyright of ViacomCBS.

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

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

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

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

The opening shot of the episode.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Both actors played their roles exceptionally well.

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

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

General Ndoye represented Earth and Titan at the diplomatic summit.

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

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

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

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

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

Tarka and Book formed an unlikely alliance.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Burnham casting her vote.

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

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

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

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

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

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

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

Star Trek: Discovery theories – week 5

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

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

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

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

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

Stamets and Culber in The Examples.

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

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

Confirmed theory:
The DMA is a super-weapon.

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

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

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

So those theories were debunked and confirmed.

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

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

The USS Discovery in Calypso.

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

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

There are still significant hurdles to overcome if the story of Calypso is to be wrapped up in Season 4, though. Obviously we have the timeframe issue: will the USS Discovery be sent back in time, be abandoned, or is Calypso taking place centuries in the future? Then we have the USS Discovery itself – it’s been retrofitted since arriving in the 32nd Century, and now looks very different to how it did in Calypso. Despite all that, however, a connection is one step closer today than it was last week.

Theory #2:
Zora will go rogue.

Zora.

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

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

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

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

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

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

The DMA as seen in Anomaly.

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

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

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

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

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

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

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

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

Could the Borg have built the DMA?

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

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

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

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

President Rillak in Kobayashi Maru.

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

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

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

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

Dr Kovich in The Examples.

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

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

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

Captain Burnham in Anomaly.

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

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

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

Stamets, Tarka, and Saru with the DMA model.

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

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

Tarka and Stamets working on their model.

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

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

So those theories are new or saw movement this week.

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

Theory #10:
We haven’t seen the last of the Abronians.

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

Theory #10a:
The Abronians’ homeworld was destroyed by the DMA.

Captain Burnham believes this image depicts a “supernova.”

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

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

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

Abronian stasis pods.

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

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

Theory #10c:
The Abronians will return to help the Federation later in the season.

A deceased Abronian.

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

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

Theory #10d:
The Abronians’ moon-ship may be useful in a later story.

“That’s no moon…”

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

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

Theory #11:
Book will find Kyheem and Leto inside the DMA.

Book and Kyheem in Season 3.

In Star Trek: Generations, Captain Picard encountered Captain Kirk inside the Nexus – despite Kirk being declared “dead” after the Enterprise-B encountered the energy ribbon almost eighty years earlier. We don’t know what the DMA is yet; one of my very early pre-season theories involved the Nexus, but that seems to be debunked already! However, the anomaly’s mysterious nature raises the faint possibility that at least some of those it appears to have “killed” may not be as dead as they first appear.

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

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

The USS Voyager-J.

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

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

Theory #13:
A major character will be killed.

A Starfleet coffin seen in Deep Space Nine.

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

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

Spock’s funeral in The Wrath of Khan.

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

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

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

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

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

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

There were several great crossovers during The Next Generation era.

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

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

Theory #15:
Michael Burnham won’t remain captain of Discovery.

Burnham in the captain’s chair.

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

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

Captain Burnham in The Examples.

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

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

Theory #16:
The ban on time travel will be explained in more detail.

HMS Bounty was able to travel back in time.

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

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

Theory #17:
The Federation has flouted the ban on time travel.

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

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

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

Theory #18:
The crew will have to defend the Verubin Nebula.

The dilithium planet is vital to the Federation.

The Federation is still in a weakened state, nowhere near as powerful as it once was. The Verubin Nebula is thus a very tempting target for anyone looking to gain an edge in a galaxy where dilithium is still in short supply. As the only known significant dilithium supply, whoever controls the Verubin Nebula will have a massive tactical advantage.

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

Another view of the planet in the Verubin Nebula.

Season 4 has presented Captain Burnham and the crew with a scientific puzzle: the DMA. But that doesn’t mean there won’t be villains in play, and Discovery has introduced us to several compelling and interesting villains over its first three seasons.

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

Theory #19:
Captain Burnham and the crew will encounter the Klingons.

General Martok, a 24th Century Klingon leader.

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

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

Theory #20:
Some areas of the galaxy – such as the Delta Quadrant – avoided the worst effects of the Burn.

Stamets with a holographic galaxy map in The Examples.

Season 4 touched briefly on the Burn with Su’Kal and Saru in Kobayashi Maru, and may now seek to put last season’s story to bed so it can wrangle with the DMA instead. But one thing I’d be curious to see is the true extent of the disaster – did it reach all four quadrants of the galaxy equally, or did its effects fade out after a certain point? Michael Burnham discovered that the Burn had a point of origin, and that it radiated out from that point like ripples on the surface of water. Ripples eventually diminish, fading away the further they travel, and perhaps that’s true of the Burn as well. There could be whole areas of the galaxy that didn’t even notice the Burn – and maybe the ship and crew will visit one such region.

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

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

The Guardian of Forever first appeared in The Original Series.

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

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

So that’s the main theory list.

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

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

Tilly’s departure feels permanent.

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

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

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

Is a fifth season going to happen?

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

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

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

So that’s it.

What adventure awaits the crew later this week?

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

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

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

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

Star Trek: Discovery review – Season 4, Episode 4: All Is Possible

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

Last week we saw Captain Burnham and the crew largely leave the gravitational anomaly behind as Discovery told three distinct stories. The main thrust of the season still involves the DMA – as the anomaly is now being called – so it was interesting to see that All Is Possible once again shelved that story to take us on another pair of side-missions.

Unfortunately Discovery’s fourth season is still unavailable to large numbers of Trekkies. Fans from Puerto Rico to Tokyo still have no (official) way to enjoy the series, and this self-defeating corporate nonsense is something I’m going to continue to call out at every opportunity. The rollout of Paramount+ internationally next year means nothing to millions of fans in Asia, Africa, and other regions when ViacomCBS believes they don’t exist.

The USS Discovery at the beginning of the episode.

Though there were secondary and tertiary plotlines in All Is Possible, there’s one massive thing that we have to talk about first and foremost: the departure of Lieutenant Tilly. I have to be honest: I did not see this coming – at least, not this early in the season. We’re four episodes into a thirteen-episode season, and Tilly’s arc has already seemingly concluded. Though I had begun to make predictions last week about Tilly’s fate after she’d been seeming so out of sorts, I figured her departure – if indeed that’s what her arc was building towards – wouldn’t have happened until nearer the end of the season.

When All Is Possible kicked off and it became apparent that we were getting a Tilly-focused story, particularly another “Tilly tries something new” story, I was worried that the episode was going to feel a bit samey after she’d played such a big role last week. And although it now makes sense in light of her departure, I’m still left wondering if it was the right decision to schedule these two stories one after the other. We had some stirrings and indications from Tilly in episodes 1 and 2 that she was feeling this way, but because that story has now effectively run its course it feels if not rushed then at least unnecessarily condensed and perhaps poorly scheduled.

This was a huge episode for Tilly – and for Discovery.

The big question, of course, is whether Tilly’s exit will be permanent. It certainly felt permanent in All Is Possible; she even got the send-off from the crew that I argued Saru had missed at the end of Season 3. I don’t usually comment on cast interviews or The Ready Room (Discovery’s social media after-show) in these reviews, but when Mary Wiseman was interviewed this week after All Is Possible had aired she said that we’d see Tilly again before the end of the season. Good news on that front, at least!

That doesn’t mean that Tilly will remain a series regular, though, and her new role at Starfleet Academy has removed her from the ship and thus presumably the bulk of the season’s remaining episodes and storylines. And if the show is renewed for a fifth season – something which is surprisingly still unconfirmed – presumably Tilly won’t be back in a starring role. I think that’s a shame in a way; she was a fun character and after three seasons was beginning to grow in confidence and settle into her role. Or so it felt.

Mary Wiseman spoke with Wil Wheaton on The Ready Room after All Is Possible aired.

On the production side of things, it’s my suspicion that the show’s writers and producers didn’t really know what to do with Tilly or where to take the character. The addition of Adira to the regular cast was a double-edged sword for Tilly because they occupy a very similar role. In Seasons 1 and 2 in particular, we’d see Tilly working in the engineering bay with Stamets. Now Adira fills that role – and because of their deeper connection with Stamets, arguably fills it better. In Seasons 1 and 2, Tilly was the “baby” of the crew; young, fresh-faced, eager to please, worried about making mistakes, and keen to do her part. Adira once again has taken over that character space.

Tilly’s growth across Seasons 1, 2, and 3 was wonderful to see, and when we compare her to characters like Harry Kim – who essentially remained in a similar space for all of Voyager’s seven-year run – we can see the advantages of serialised storytelling. But Tilly’s growth as a character appears to have come at the expense of her roles on the ship, and the addition of Adira may well be the proverbial last straw. We can kind of see the snowglobe scene through this lens – Tilly was passing the metaphorical torch to Adira in that moment.

Tilly gave her snowglobe to Adira.

We can’t ignore the rumours of a Starfleet Academy series when discussing Tilly’s fate and future. Alex Kurtzman, who’s in charge of the overall Star Trek franchise for ViacomCBS, hinted that such a series is in the early stages of being worked on, and in more ways than one the Tilly side of All Is Possible feels almost like a backdoor pilot for such a show. We got to see Tilly both as a teacher and a leader across these sequences, laying the groundwork not simply for her departure from Discovery, but setting up her new role as well. Could all of that mean that the potential Starfleet Academy series would feature Tilly in some capacity?

I thought Mary Wiseman’s comment in The Ready Room that Tilly’s confidence had been knocked by the events of Season 3 was particularly interesting, too. Tilly had seen herself as being on a pathway that led her from the Academy to the captain’s chair, but when she got a taste of what being in command was like, she found herself out of her depth as she lost the ship to the Emerald Chain. I think a lot of us can relate to feeling overwhelmed by a difficult situation, or feeling the weight of responsibility and struggling with it. Perhaps, as Wiseman suggests, Tilly came to believe that command was not right for her.

Tilly came to believe that she was on the wrong path.

If that’s true, whose fault is it? There was a lot of talk during Season 3 that Saru’s decision to appoint Tilly as acting first officer was the wrong one, and while I defended that story point at the time, when seen through this new lens perhaps we could argue that Saru pushed Tilly to take on that role too quickly. He’s been a good friend to her, and has advocated for her when others might overlook her – as we saw last week, for instance – but might his friendship with Tilly have blinded him, at least somewhat, to her inexperience and limitations? Perhaps.

Tilly held her own when the Emerald Chain captured the ship, and ultimately played a huge role in retaking Discovery and defeating the villainous faction once and for all. But of course it makes sense that those events would completely bowl her over. She was in command of Discovery for a few hours at most, then lost the ship to the Emerald Chain with relative ease. As someone who’d hoped to one day have her own command, those events are going to take a toll, and it’s natural that she’d question her career path in light of what happened. We can empathise with Tilly, putting ourselves in a comparable situation.

Tilly had hoped to one day command her own ship.

It was sweet to see Tilly reunite with Captain Burnham, albeit briefly, before confirming her decision and departing the ship, and the choice of Tilly’s cabin for this conversation harkened back to the early part of Season 1 where we saw them together in that room on multiple occasions. Tilly had already made her decision, it seemed, before Burnham even sat down. Yet it was still nice to see her talking it out with her captain – and friend – before finally confirming that this is what she was going to do. The moments between Mary Wiseman and Sonequa Martin-Green added a lot to this story.

One person who was missing from Tilly’s story, though, was Stamets. Not only had Tilly and Stamets worked together since the beginning of the series, but earlier in the episode Tilly had expressed concern about “abandoning” him to go on the Academy mission – yet by the end of the episode she was content to leave him all alone with the problem of the DMA while she took on a new role. I think we could still have arrived at this point; I’m not saying Tilly needed to stay behind for Stamets’ sake or anything. But just as it was sweet to see her with Burnham talking things out, I think we could have also enjoyed a quiet scene between Tilly and Stamets in which she at least said her goodbyes. As it is, we saw Stamets incredibly briefly as Tilly left the ship, but that was it.

Stamets was noticeably absent from Tilly’s story.

This is the second story in a row from which Stamets has been absent after he missed Gray’s incorporation last week. I confess I’m not exactly sure what’s going on there – whether it’s simply a case of writing/editing (Stamets actor Anthony Rapp confirmed on social media that at least one of his scenes this week had been cut) or whether there’s some other reason for the lack of Stamets in some of these stories. He has a deep connection with Adira, which made his absence from that story last week feel very odd, but he also has a friendship with Tilly – so again, his absence from her story aside from one mention right at the beginning makes it feel like there was something missing; someone else she needed to talk to before departing.

One thing that wasn’t made clear is this: what exactly is Tilly going to teach? I presume it must be something scientific; she can’t be lecturing on subjects like command, surely? Starfleet Academy has usually been presented as something akin to both a military officers’ training college and a civilian university – with different teachers for different subjects. Tilly has a scientific background, so presumably she’d teach something in that department. Or maybe Federation history… since she’s 1,000 years older than all of the cadets! Perhaps this is something we’ll see more of either later in the season or in that potential Starfleet Academy show.

Will we soon see Tilly back on our screens in another Star Trek series?

We haven’t even talked about Tilly’s mission! She and Adira led a small group of cadets on what was supposed to be a training mission – but in true Star Trek style, things didn’t go to plan. I confess at first that I felt sure the whole thing was either a setup or a simulation, especially because of the involvement of the mysterious Kovich. However, it doesn’t seem like that was the case; Tilly’s shuttle really did crash-land on an icy moon, and the monsters she and the cadets had to escape from were real.

It wasn’t clear how much time had passed since the season premiere, when we were first told that there would be a new intake of cadets, so we don’t really know how long these cadets have been together. However, I felt that some of the tension between them was a little forced. The whole point of Starfleet Academy, especially in a post-Burn galaxy, is to work together and pull in the same direction, yet we had exaggerated moments of drama and tension between the cadets that just didn’t feel natural even in that context.

Adira and Tilly with the trio of cadets.

Even if many people in the galaxy harbour prejudices or preconceptions about other races and people from beyond their homeworlds, why would anyone who felt that way apply to join Starfleet? Surely we should be seeing if not “the best of the best” then at least folks who are superficially willing to work together; it kind of felt like the cadets were from some semi-scripted reality TV show, the kind that deliberately chooses the most belligerent contestants with clashing personalities. In that sense, I didn’t really like any of the cadets.

They had to start from a place that would allow them to come together, and in particular that would allow Tilly to be the catalyst for their coming together, and I get that. But it just felt like Discovery, not for the first time, had taken things to an unnecessary extreme in order to accomodate this storyline, putting up one-dimensional characters who behave unnaturally solely for the sake of presenting Tilly with an obstacle and a point of contrast. The young actors who played the cadets did very well with the material they had, but their characters were written rather poorly, in my view, and none came across as feeling either like a natural character nor someone we’d expect to find at Starfleet Academy.

Cadets Harral (left) and Gorev didn’t get along at first.

The puzzle that lay before Tilly and her crew felt like it came right out of The Next Generation’s era, and I’m absolutely there for that kind of story! After the shuttle crash the group was unable to stay aboard, instead needing to climb out of the crash site to use their communicators – but were unable to use their technology. This angle definitely added a lot to the story, forcing Tilly and everyone else to think outside the box rather than being able to fall back on phasers, tricorders, and the like. Again, this feels like a story that could’ve come from any of the 24th Century Star Trek shows and was a great throwback to the franchise’s past.

On a personal note, I have to confess that I’m sad to see Tilly go. If the move is permanent, as it seems to be at this stage, her absence from Discovery will be noticeable going forward, even if Adira steps up to fill the void she leaves behind. I liked Tilly as a character so much that one of my cats is named Tilly (if you want to see a couple of photos of her, follow me on Twitter!). Tilly didn’t just fill that “young and eager” role that characters like Harry Kim, Nog, Hoshi Sato, and Wesley Crusher had in past iterations of the franchise. She was always more than just a character archetype. Tilly was strong in her own way, brilliant in her own way, and funny to boot.

Tilly’s departure is a bittersweet moment.

Across the show’s first three seasons we saw Tilly as a scientist and engineer, working with Stamets on the Spore Drive. We saw her as a friend to Michael Burnham and Saru in particular. We saw her passionate about helping the jahSepp in the mycelial network, and how she came to the aid of Po in the Short Treks episode Runaway. She grew and developed from an anxious cadet into a true Starfleet officer – and while she will undoubtedly make an excellent teacher to a new generation of cadets, her departure is a sad one. She may yet have a role to play either this season or in Star Trek’s future, and I look forward to that. But for now, it seems as though Discovery is moving on without her. And I’m sure I’m not the only one who feels a stab of sadness as a result.

Just like Discovery plans to do we’ll leave Tilly behind and move on to take a look at the rest of the episode. There was a secondary storyline that involved Captain Burnham, Saru, President Rillak, and Ni’Var’s leader T’Rina. We talked last week about contrivances and forced drama, and in this story I’m afraid we did get some of that for the second week in a row. At what was supposed to be the final moment of negotiations to bring Ni’Var back into the Federation, the Ni’Var delegation dropped a diplomatic bombshell that appeared to sabotage the entire thing.

The negotiations on Ni’Var.

Both the timing of this and the way it was pretty easily resolved feel rather contrived – and it begins to stretch credulity to think that neither the Federation nor Ni’Var negotiators could’ve come up with Captain Burnham’s “independent committee” solution on their own. It seems like the perfect compromise, allowing Ni’Var the backdoor they needed without compromising the Federation’s unity. Captain Burnham wasn’t the only person capable of proposing such a solution, and while her status as a citizen of Ni’Var and the Federation makes her well-qualified to serve, I have to ask if she’s the only citizen of Ni’Var who’s also in Starfleet at this point. It seems quite plausible that there are others, and thus her claim to be “uniquely” capable of coming up with this solution might be stretching the truth somewhat.

All that being said, these negotiations reminded me very much of the negotiations that my country, the UK, has been taking part in for much of the past five years. I don’t know whether this story was intentionally written as an allegory for Brexit, but it certainly felt like it had elements of that, and to my surprise it was handled in what felt like a mature way. Brexit, much like certain American political issues, divides opinion sharply, and it would be very easy for a story like this one to come down firmly on one side of the fence, presenting one side as morally right and the other as morally wrong. All Is Possible didn’t do that, and instead tried to find a way to cut through the political machinations of both sides before ultimately settling on a compromise.

Captain Burnham’s compromise can be read as a metaphor for our current divided political climate.

If we ever needed Star Trek to shine a light on contemporary issues through its sci-fi lens, we need it at the moment! There are so many divisive political topics, including Brexit, all across the world. What we’ve seen over the past decade or more are moves away from the political centre ground toward the extremes of left-wing and right-wing politics. The art of the political compromise has been lost in too many cases, and that’s a driving force for further division. Finding ways to compromise and to maturely understand that it isn’t always possible to have everything your own way is something politicians of all ideologies – and their supporters – need to understand, and Discovery delivered this message in a simple yet meaningful way.

It wasn’t the perfect story, as I’ve tried to explain. It had its contrivances that definitely felt forced. But at the same time, any British or European person can tell you that, having watched years of Brexit negotiations, such things aren’t as unrealistic as they might seem. Diplomats for both sides have, at times, seemed to be negotiating in bad faith, waiting to spring the next trap or throw in a new uncompromising proposal at the last minute. It’s a wonder that the Brexit negotiations got as far as they did, all things considered!

President T’Rina was happy with the proposed compromise.

So perhaps calling this story “contrived” was too harsh in light of what we’ve seen in the real world! Though I maintain it’s a story with some imperfections, it was an interesting one nevertheless. Star Trek has tackled many political issues in its long history, from nuclear proliferation to the teaching of religion in schools, but this is one of the first stories to really feature politicians and diplomacy as a key part of the narrative, with nakedly political considerations having to be taken into account by our heroes. That alone makes it a very interesting story.

It was wonderful to welcome Ni’Var back into the Federation after seeing how many worlds had quit the organisation last season. It definitely feels as though the Federation is now making significant strides in reforming; Ni’Var is the first of the “original” member worlds to rejoin as far as we know. Perhaps we’ll see Earth do the same one day soon? It would be a shame if Discovery left that particular storyline unresolved, especially after we saw how isolationist Earth had become in Season 3.

Ni’Var has rejoined the Federation!

President Rillak once again showed her almost Machiavellian political style; her willingness to lie and use truly underhanded tactics to get her way without revealing the extent of her meddling. By sidelining Admiral Vance and bringing in Captain Burnham and Saru, she was able to execute a hidden plan to bring Ni’Var back into the fold and negate their last-second demand. It was, all things considered, a brilliant tactical move on her part – and re-emphasises her uncompromising nature and willingness to bend or even break the rules to advance the Federation’s best interests.

Despite what appeared to be a détente between Captain Burnham and President Rillak toward the end of the episode, I hope Discovery’s captain keeps her wits about her. If we’ve learned anything about President Rillak over these four episodes, it’s that she sees everything and everyone around her as means to an end. Working with Captain Burnham was, in this instance, advantageous to her – but Rillak will throw Burnham into the fire, and Discovery along with her, if she believes it will help her cause or advance what she considers to be the best interests of the Federation.

Captain Burnham would be well-advised to beware of President Rillak… no matter how superficially friendly she’s currently being.

We haven’t seen President Rillak do anything completely immoral or “evil” just yet. And Discovery may choose to keep this nuanced presentation going all season long. I kind of hope that’s the case, because right now I’m loving President Rillak’s “ends justify the means” approach to governing. Chelah Horsdal plays the character expertly. But Rillak is the kind of character with whom a major confrontation feels increasingly inevitable – her moral ambiguity and Captain Burnham’s moral certainty feel like they’re on a collision course.

There was a third storyline this week that involved Book and Dr Culber. As with Stamets, Book found a new but fun pairing with Culber and I hope they revisit this character pairing in future; it would be great to see them socialising or doing something else outside of a therapy setting. There seemed to be a hint that Dr Culber might need help processing his own trauma – perhaps from his time trapped in the mycelial network – in future, and if so maybe Book could have a role to play there.

Dr Culber may need some help of his own one day.

The programmable matter that Dr Culber and Book turned into sand reminded me a lot of the sequence from Lower Decks Season 1 where a character is in the process of “ascending.” Maybe that was unintentional, and tonally these sequences could not be further apart! But it was interesting to see nevertheless – or perhaps I’m grasping at straws as I desperately hope for the producers of Star Trek to do more to bind the franchise together!

Grief and loss have been themes that Discovery hasn’t shied away from, but they’ve come to the fore this season. Book and Tilly’s stories both connect to this theme as they’re both experiencing different kinds of loss. In a sense, everyone aboard Discovery is in Book’s shoes – they’ve all lost everyone they ever knew apart from each other, albeit in very different ways. And we’ve seen different ways of coping with that loss. Book seems to have made a small breakthrough this week, and I hope we see that process continue.

Book spent this week’s episode in counselling.

Captain Burnham, in Season 3, seemed to rebel against the confines of Starfleet for a time. At first I called this a character regression, as I felt it risked dragging her back to her early Season 1 portrayal. But thinking about it again, through this lens of loss and grief, I think we can see that Burnham is processing the loss of her friends, her family, and the world she had to leave behind. She did so at first by seeking freedom, then later by reconnecting with her mother and reaffirming her relationship with Starfleet. In Tilly’s case, she couldn’t make that renewed commitment and has chosen to walk a new path. Book’s destination is still unknown as he’s still processing his own loss and grief – and I’m glad. What Book has gone through is almost unfathomable, and it wouldn’t feel right if this element of his story and characterisation were resolved too soon.

So that was All Is Possible. Tilly’s departure is by far the biggest thing to come out of the episode, and while there were some minor gripes with the way both Tilly and Burnham’s stories unfolded, ultimately they end up feeling like little more than nitpicks in what was a solid, thoroughly enjoyable episode. I’m glad to see Discovery sidestepping the main serialised story and being bold enough to give us these semi-standalone episodes. I have no doubt that some elements will come back into play later in the season, but for the most part what we got is a self-contained story – albeit one with huge implications for the series going forward.

Onward to new adventures.

Unlike when Nhan and Georgiou left last season, I’m not scrambling around wondering who will replace Tilly. That question has already been answered: Adira. However, her departure does potentially open up another space for a new crew member – and with noteworthy absences in departments like security and tactical, perhaps we could be set for someone new to be promoted. Gray is perhaps the most readily apparent choice, but there are great cases to be made for Detmer or Owosekun to get bigger roles on the bridge, as well as for the return of Nhan, or even for a new character to be introduced.

A few scattered final thoughts: is Kovich the head of Starfleet Academy now? Has he always been in that position? I don’t recall him being referred to as “doctor” last season, but he could be some kind of professor holding a PhD. That’s an interesting take on the character! At first I wondered if he was responsible for the shuttle going off-course… it seems like something he might do! Beginning the episode with a traditional captain’s log was awesome, and another great callback to past iterations of the franchise. I believe this was the first time we heard a 32nd Century stardate, too.

Kovich made his first appearance of the season.

It was neat to see the Season 3-style uniforms being used for some secondary characters. Season 3 of The Next Generation and the film Generations both showed that there’s a kind of transition period when uniforms are being changed over where not everyone has the new variants, and that seems to still be true in the 32nd Century. I was a little worried when Admiral Vance seemed to have been shuffled out of the story in favour of President Rillak – but it makes perfect sense. Vance isn’t a politician and wouldn’t be capable of doing the kind of things we saw Rillak doing this week. Nor would I want to see Vance go down that road. Finally, is there a blossoming romance between T’Rina and Saru? I certainly felt the show was hinting at something to come!

Although it was bittersweet to say goodbye to Tilly, All Is Possible was a good episode all around. It didn’t feel overcrowded, which episodes with multiple competing storylines sometimes can, it had some well-made visual effects particularly on Tilly’s away mission, and though the politicking was somewhat contrived in one respect it was still genuinely interesting to see Star Trek trying something different. I think for me, All Is Possible is the high point of Season 4 so far.
