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.

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.

Star Trek: Discovery Season 4 is available to stream now on Paramount+ in the United States, Scandinavia, Latin America, and Australia.

Star Trek: Discovery theories – weeks 1-2

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

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

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

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

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

Book in Discovery’s Spore Drive cube.

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

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

The USS Discovery makes a Spore Drive jump.

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

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

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

A new name has been spotted in the opening credits!

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

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

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

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

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

President Rillak in Kobayashi Maru.

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

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

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

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

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

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

Captain Burnham.

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

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

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

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

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

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

A holographic representation of Gray’s synthetic body.

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

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

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

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

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

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

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

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

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

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

Could the anomaly be similar to V’Ger?

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

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

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

The USS Voyager-J.

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

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

Captain Saru.

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

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

Theory #7: The gravitational anomaly is a superweapon.

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

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

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

Theory #7a: The Borg are responsible.

A Borg drone seen in The Next Generation.

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

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

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

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

Theory #7c: The Kelvan Empire is responsible.

Rojan, a representative of the Kelvan Empire.

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

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

A Sphere-Builder seen in Enterprise.

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

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

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

Theory #8: A major character will be killed.

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

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

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

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

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

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

Voyager’s Doctor is a contender!

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

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

Could Sutra still be alive in the 32nd Century?

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

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

Theory #10: Burnham may not remain in the captain’s chair.

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

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

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

Captain Burnham in Anomaly.

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

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

Theory #11: Kovich works for Section 31.

Kovich in Season 3.

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

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

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

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

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

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

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

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

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

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

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

The USS Discovery seen in Calypso.

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

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

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

The dilithium planet at the centre of the Verubin Nebula.

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

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

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

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

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

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

The Klingons have been part of Discovery since the beginning.

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

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

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

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

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

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

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

Carl – the Guardian of Forever’s new persona.

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

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

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

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