Star Trek: Discovery Season 4 – new trailer analysis

Spoiler Warning: There are spoilers ahead for Star Trek: Discovery Seasons 1-3 and the trailers for Season 4. Minor spoilers may also be present for other iterations of the Star Trek franchise.

As many folks had predicted, 2021’s New York Comic-Con saw a brand-new trailer for Star Trek: Discovery’s impending fourth season make its debut! The trailer was certainly jam-packed with action and plenty of teases, and gave us a tantalising glimpse of the “gravitational anomaly” that seems to be at the core of the main storyline. Though there will almost certainly be smaller sub-plots and one-off stories like last season, the trailer mostly focused on Captain Burnham and the crew’s attempts to tackle the unknown anomaly.

First of all, none of the theories that I posited a few months ago about the nature of the gravitational anomaly now seem to be anywhere close to plausible! I had a feeling that this would be the case; that Discovery would once again create something wholly new rather than rely on a phenomenon we’d seen in a past iteration of the franchise.

Discovery is coming back in just over a month!

Captain Burnham was heard in the trailer telling her crew that the anomaly was unlike anything the galaxy had ever seen, and that once they “enter” it, they will be literally going “where no one has gone before.” I appreciated the callback to the line heard over the opening titles of The Original Series and The Next Generation – it’s a line which encapsulates Star Trek’s spirit of exploration with a side of adventure, and to me the use of that phrase represents Discovery staking its claim to be the successor of those exploration-focused shows.

Between what Burnham and Stamets had to say about the newness and unknown nature of the anomaly, we can seemingly rule out any connection to things like the Nexus, a graviton ellipse, and Tyken’s rift – as well as anything else we’ve seen before in Star Trek. That isn’t to say there categorically will not be any connection to other Star Trek stories, but that the anomaly itself will be something altogether new.

A beautiful CGI shot of the anomaly.

As mentioned, we got a couple of glimpses of what seems to be the anomaly itself. The first time we saw it it seemed to resemble a black hole within a black hole within a black hole… a kind of recursive black hole phenomenon. Discovery’s second season showed off a great recreation of a black hole (that was actually a Talosian illusion) and while the anomaly seen at the beginning of the trailer was different, especially in terms of colour, the design is comparable.

The second time we saw the anomaly in the trailer it looked very different, as though a “rip” or “tear” in the fabric of the universe, surrounded by glowing light but appearing as a dark smear. Unlike the black hole-inspired visual effect seen near the beginning of the trailer, this second look at the anomaly didn’t feature the same light-bending effect, nor was anything inside the anomaly visible.

The USS Discovery approaches the anomaly.

Of the two depictions that seem to be of the anomaly – assuming that they are, in fact, both supposed to represent the phenomenon – the first black hole-esque look is, from purely an aesthetic standpoint, my favourite. It was more memorable and different, and the way the anomaly bent light around it seems more in line with its stated gravitational effects. The “dark smear” was fine – but it wasn’t particularly visually exciting, and could have represented any one of dozens of anomalies seen in past iterations of Star Trek.

There were some short sequences that could be taking place on the other side of the anomaly, depending on how we view things. There seemed to be glimpses of characters fighting with swords, a large explosion, a forest that looked a lot like Su’Kal’s holographic world, and a child in a forest that could all be taking place after the USS Discovery enters the anomaly. We’ve seen parallel universes and different dimensions in Star Trek on a number of occasions, and I wonder if this anomaly could be the gateway to a different dimension once again.

Could this be on the “other side?”

But that’s enough story speculation for now! We won’t know more about the gravitational anomaly until the season kicks off in just over a month’s time, so let’s take a look at some of the other imagery from the trailer to see what else we can discover.

Firstly, it looks as though Ni’Var – the new name for Vulcan since the reunification of Romulans and Vulcans – will indeed rejoin the Federation. A brief scene showed the Federation president – a character identified during the Comic-Con panel as a part-Cardassian, part-Bajoran, part-human character named Rillak – presenting the leader of Ni’Var with a folded Federation flag. This was something teased during the epilogue of Season 3, with Saru’s diplomatic initiatives seeming to bear fruit.

Captain Burnham looks on as the Federation President gives a flag to the leader of Ni’Var.

Speaking of Saru, after being unceremoniously shuffled out of the captain’s chair in that same epilogue sequence to make way for Michael Burnham, he was back in uniform in the new trailer. The first trailer only showed us a glimpse of Saru out of uniform, and there was confusion over the position he could have both aboard the ship and within the new story after taking a leave of absence and returning to Kaminar.

Saru’s role still isn’t clear – he seems to retain the rank of captain but hasn’t been restored to the captaincy of Discovery. He was also depicted wearing a different badge on his uniform alongside his combadge – I wonder if this might indicate a diplomatic role of some kind. Regardless, it’s great to see Saru back on the ship, and presumably he’ll be part of the crew. What role he will play in the ship’s command structure as an ex-captain is still not clear, though.

Saru is back in uniform – and is sporting a new badge!

I couldn’t identify every single alien race seen in the trailer, but there were quite a few! At Federation HQ we saw an Orion woman not wearing a Starfleet uniform; she could be a representative of the Emerald Chain – or whatever remains of it. There seemed to be Tellarite crew members aboard Discovery, as at least one was present during an away mission. Also featured prominently at Federation HQ was a Ferengi Starfleet captain.

I liked the Ferengi design; it felt familiar enough to be obvious, while at the same time taking advantage of improvements in prosthetic makeup that have been made since the Ferengi debuted. There was more detail in this Ferengi’s face and ears than we ever saw in the likes of Quark and others. That isn’t to say the older makeup and prosthetics were bad, just that there have been advancements in the thirty-five years since the Ferengi were originally created! After Season 3 teased us with glimpses of Cardassians, Andorians, and Lurians who ultimately played no role in the story, I’m not getting my hopes up that this new Ferengi character will play a major part in the story of the season – but you never know!

The Ferengi captain.

The existence of President Rillak seems to conclusively rule out the idea that the mysterious Kovich is in charge of the Federation. This had been a rumour or theory that some fans seemed to be quite attached to last time, but I was convinced for much of Season 3 that Kovich is in fact the head of Section 31 – or perhaps Starfleet security. We saw Kovich very briefly in the trailer, and previous statements from David Cronenberg – the famed director who plays the character – had already confirmed that he will be back in some capacity in Season 4.

Tilly appears to have been promoted to lieutenant, at least based on the emblem she’s wearing on her collar in the trailer. Whether that will happen off-screen isn’t clear, but it would be kind of neat after her arc in Season 3 to see her rewarded with a promotion. Tilly was originally Burnham’s choice for first officer, but with Saru back perhaps he’ll fill that role? Either way, it seems that Tilly will be returning to the sciences division and not wearing the red uniform of the command division – something that was ham-fistedly digitally edited in the Season 3 finale!

Tilly is back in science division blue.

Dr Gabrielle Burnham and the Qowat Milat are making a return as well, as we saw them involved in a couple of different scenes during the trailer. It wasn’t clear whether the scenes we saw were all taken from the same episode or not, so the Qowat Milat could be in more than one episode. It was great that Discovery found a way to connect with events from Picard Season 1 in this way, and I wonder if we’ll get any other callbacks to the events of Discovery’s sister show. Due to the pandemic and its associated disruptions, Picard Season 2 won’t arrive until after Discovery Season 4 – though the original plan was surely for things to be the other way around!

We got brief looks at Dr Culber, Adira, and Gray. Gray will supposedly be made visible this season after finally being seen by Dr Culber in the Season 3 finale. The short scenes featuring Adira and Gray in the trailer weren’t clear as to Gray’s visibility, and when Adira interacted with Tilly, Gray wasn’t present. But at the Comic-Con panel, Wilson Cruz teased that Gray will indeed become visible and that he may have a connection to the season’s main story in some way!

One of the most interesting shots from the teaser showed Michael Burnham pulling back a shroud over a reptilian-looking alien. This alien seems to be dead, but interestingly seemed to be noticeably larger than the humanoids we’re used to seeing in Star Trek. That could be a consequence of how this one scene was framed, but the idea of aliens – perhaps from inside the anomaly – being “more alien” in appearance is an interesting one in theory. I don’t believe we’ve seen this species before, though the dead alien’s reptilian-inspired look has superficial similarities to a few past Star Trek races.

Burnham with the dead alien.

There was a shot on a snowy planet that I was also taken by. I wonder if this might be a return to the Guardian of Forever’s new homeworld – the one seen in the two-part Season 3 episode Terra Firma. That’s just a gut feeling and it could be somewhere else entirely, but it would be interesting if Discovery didn’t just abandon the Guardian of Forever. If the crew are on a quest to understand a completely alien and unknown phenomenon, the Guardian could be a good place to start. Maybe it has encountered the anomaly before, or at least is aware of it and knows something about it?

Is this scene taking place on the Guardian of Forever’s planet?

Book and Grudge were back – thank goodness! David Ajala was such a wonderful addition to the cast, providing the Starfleet crew of Discovery with an outsider’s perspective while serving as a guide of sorts to the 32nd Century. And Grudge is beautiful, of course! Book’s ship also made a return. We caught a glimpse of Book in the Spore Cube – his telepathy allows him to serve as Discovery’s navigator alongside Stamets. This could be an interesting source of conflict; how will Stamets feel about someone else muscling in on his job? But at the same time the ability of Book to navigate the mycelial network opens up the Spore Drive’s potential. With multiple navigators available – perhaps millions of potential navigators if any Kweijian or anyone who’s telepathic can take on the role – the Spore Drive could finally be rolled out to other Starfleet vessels.

Whether that will actually happen in Season 4 or not is still an open question, but I think finding a way for the Spore Drive to be more than just a gimmick to be used occasionally by Discovery is a good direction for the series to take. With the show now set in the far future of the 32nd Century, it wouldn’t tread on anyone’s toes in terms of canon – and it would be a great way for Starfleet to mitigate the dilithium shortage and future-proof their fleet. I might write this one up as a full theory, so watch this space!

I couldn’t resist including Grudge!

The visual effect of the crew lifted out of their seats by the anomaly’s gravitational effects is stunning. We’re not really used to seeing artificial gravity failures in Star Trek. Aside from The Undiscovered Country, I can’t really call to mind a time where the failure of a starship’s artificial gravity was a significant story element. Even when ships are badly battered and at the point of destruction, artificial gravity usually continues to function! If Discovery uses this effect sparingly I think it could be very impactful in Season 4.

We saw several members of the cast – and a number of unidentified characters – involved in hand-to-hand violence. Some of this looked utterly barbaric, not at all the kind of thing we’d expect from Starfleet officers. At one point the Qowat Milat even seemed to be engaging a Starfleet officer. I wonder if this is all connected to the anomaly – perhaps things on the other side are more violent, like they are in the Mirror Universe, for example? Or perhaps the anomaly has different effects on people, driving some to become violent? Either way, there seemed to be a lot of that on show in the trailer, and some sort of explanation is required!

Captain Burnham looks on while Owosekun appears to be involved in a fight. This was just one of many examples of hand-to-hand violence seen in the trailer.

Though present, Admiral Vance didn’t have much to say in the trailer. I’m glad he’s coming back, though, as he was a great character in Season 3 as someone who embodied the values of Starfleet. We saw several scenes set at Federation HQ, which was of course Admiral Vance’s home base in Season 3. HQ seemed to look at least a little busier in the trailer than it had in Season 3; this could be a visual representation of the growth of the Federation as it begins to bring back wayward members and expand its fleet. The inclusion of President Rillak may mean Admiral Vance has less to do; both characters seem to occupy a similar role as superiors to Captain Burnham.

Speaking of Captain Burnham and President Rillak, a scene appeared to show Discovery’s captain receiving a stern telling-off from the Federation president. My suspicion is that this is something that happens early in the season prior to the discovery of the anomaly. That’s definitely just a gut feeling, but something about this conversation seemed to suggest the stakes weren’t quite so high. Perhaps Burnham did something in an early mission to earn the president’s ire, but the grave threat of the anomaly will force them to work together despite their differences of opinion and leadership styles.

President Rillak apparently doesn’t like Captain Burnham.

This sequence, out of everything we saw in the trailer, was my least-favourite. It felt like forced drama for the sake of forced drama, and the use of the word “bravery” when giving an officer a dressing-down was incredibly clumsy dialogue. It was a way to communicate to us as the audience that Burnham is brave and that she’s some kind of maverick who doesn’t always conform or do what authority figures tell her – but it just felt a little too forced. We know Burnham doesn’t always play by the rules having seen the way she operates over three seasons, and having a brand-new character dropped in to reinforce that point may not be the best use of the show’s time. I’ll reserve judgement until I’ve seen the full sequence in context, but in the trailer I didn’t like the way it came across.

So I think that’s all I have to say for now. Stay tuned because there are a couple of nascent theory ideas that I have based on the trailer, so it’s possible they could get the full write-up treatment in the days ahead. Discovery Season 4 is offering another “natural disaster” storyline after the Burn in Season 3, and that may not be to everyone’s taste. However, I confess to being genuinely curious to learn more about this anomaly. What is it? What danger does it really pose? Could it be a weapon rather than a natural occurrence? There are many, many questions running through my mind!

Whatever the ultimate cause of the anomaly, Season 4 looks like it’s on a good track. The trailer was action-packed and exciting, with ample interpersonal drama and an awful lot to unpack. I’ve tried to hit the main points here, but I’d encourage you to check out what other fans and publications have to say as they break down the trailer, as I’m sure there are points I missed or overlooked.

I’m really looking forward to Discovery Season 4 now, and with barely a month left there’s not long to wait. When the new season arrives I’ll be writing reviews of each episode and probably indulging in a spot of theory-crafting, just as I did during Season 3 last year. I hope you’ll stay tuned for that here on the website!

Star Trek: Discovery Season 4 will debut on Paramount+ in the United States on the 18th of November 2021, and on Netflix in the United Kingdom and elsewhere a day later. Star Trek: Discovery Seasons 1-3 are available to stream now.

Star Trek: Discovery theories – week 11

Spoiler Warning: There are spoilers ahead for Star Trek: Discovery Seasons 1-3, Star Trek: Picard, and other iterations of the franchise.

Su’kal was an interesting episode. It’s also one that, as I noted in my review, is hard to judge fairly before we know the ultimate outcomes of several of its key story points. I’m split on the revelation of the mentally challenged Kelpien Su’kal being the cause of the Burn – the biggest disaster in galactic history. While on the one hand it’s an interesting way to go, and one that is similar in some respects to older Star Trek stories, on the other hand it’s anticlimactic, coming in the eleventh week of the season. There’s a huge disparity between the small, terrified Su’kal and the Burn – an event which caused devastation on a galactic scale and destroyed the Federation. And there is a worrying message underneath the sci-fi trappings, one which risks further stigmatising mental illness and those with learning disabilities.

But that’s enough about that for now. Read my review if you want my full thoughts on Su’kal and what it brought to the table. We’re here for theories! And there’s a lot to get through this time. We got two confirmations, five debunkings, and there’s also one theory I’m choosing to retire. Let’s briefly look at each of these before hitting the main list.

Confirmed theory #1: The Emerald Chain will attempt to steal the USS Discovery and/or the Spore Drive.

Discovery held captive by Osyraa’s flagship.

Aside from the revelation that Su’kal caused the Burn, this was the biggest event in the episode. Osyraa – the Emerald Chain’s leader – showed up at the Verubin Nebula aboard her flagship and was able to very easily capture Discovery. How she came to know about the Spore Drive is unclear, as is how her ship magically became so powerful since its last meeting with Discovery. However, she not only attempted to capture Discovery and the Spore Drive this week, she succeeded.

Confirmed theory #2: The Emerald Chain will attack Federation HQ.

Osyraa set course for Federation HQ.

After capturing Discovery, Osyraa set out to her next objective – Federation HQ. Though this attack didn’t take the form I expected, Osyraa is headed there to take on Starfleet. Whether she will pull her forces away from Kaminar to join her as her flagship and Discovery travel to Starfleet HQ is not clear, but it would be a reasonable assumption. We will see exactly what happens next time, including how successful her attack is. But we can consider this theory confirmed.

Debunked theory #1: A time-travelling (or parallel universe) USS Discovery is at the centre of the nebula – and may be responsible for the Burn.

The USS Discovery.

As far as we can tell, only the Kelpien ship was in the Verubin Nebula. Given Su’kal’s connection to dilithium and the Burn, it certainly seems as though this is the way the story of the season is going. Additionally, the nebula looks very different from the one encountered by Craft in Calypso, meaning the chances of a crossover between that story and this one now seems remote.

It was an increasingly distant possibility, especially after the discovery of the Kelpien ship. The departure of Georgiou – who was the character I suggested may have taken Discovery back in time in the event that this theory was true – also decreased its probability. With only two episodes remaining, Discovery having already entered the nebula, and with an explanation for the Burn at least halfway explored, changing tack now to suddenly put the USS Discovery in the nebula would be difficult to pull off at best.

Debunked theory #2: A familiar starship is at the centre of the nebula – and may be responsible for the Burn.

The USS Cerritos from Star Trek: Lower Decks.

As above, it seems certain that the explanation for the Burn lies with Su’kal and the crashed Kelpien ship. Between continuing to explore these story threads and depicting the battle to retake Discovery from Osyraa, there is no time left in the remaining couple of episodes to suddenly drop in another familiar starship and give such an important moment the respect it needs.

As such, we can consider this debunked.

Debunked theory #3: The Red Angel suit is at the centre of the nebula – and may be responsible for the Burn.

The Red Angel.

As above, it’s the Kelpien ship in the nebula – and as far as we can tell, not much else. While the prospect of the Red Angel suit accidentally causing the Burn was a fascinating one, it may have been a bridge too far for Discovery in the end. As Saru and Culber remain behind to help Su’kal, and with everyone else off trying to retake the ship, there seems to be no place for the Red Angel in this storyline.

Debunked theory #4: The name “Burn” is derived from the name Burnham.

Michael Burnham did not cause the Burn!

This theory was intrinsically linked to the one above. As I noted the first time I discussed the Burn, it was odd, in a show that has always put Burnham front and centre, that there was a catastrophic event which happened to share part of her name. It seemed at least possible that there would prove to be a Burnham connection, just as there was with the Red Angel in Season 2. However, with the discovery of Su’kal and the Kelpien ship, it seems impossible for the story to go in a Burnham-centric direction this time, which is nice!

Debunked theory #5: Tilly is going to go rogue.

Tilly in the captain’s chair.

When Tilly became first officer, I was struck by one word in particular: “compliant.” That’s what Tilly thought Saru considered her to be, and I speculated that she may have ended up disobeying orders in a future story. However, it now seems clear that the reason Tilly was chosen was to be an inexperienced commander, making Osyraa’s victory and capture of Discovery more plausible. With Discovery under Osyraa’s control and Saru away on the Kelpien ship, it’s hard to see how this could pan out.

So those theories are considered debunked – even if, technically, we didn’t see 100% confirmation on all of them! Before we hit the main list I have one theory that I’m choosing to retire, and it’s connected to two theories above.

Retiring theory: Burnham’s Red Angel suit has been stolen.

Burnham with the suit on Hima in That Hope Is You.

With the Red Angel suit clearly not in the Verubin Nebula – and as far as I can tell given only two episodes remain, not connected to the story of the season at all – I’m retiring this theory. Burnham set the Red Angel suit to self-destruct after delivering the final Red Burst for Pike and Spock to see, and as we saw in the finale of Season 2 they got the message.

In order for someone to have been able to capture it, they would have had to know exactly when and where the suit would be, and if time travel has indeed been outlawed – as Admiral Vance told us – no one would be able to recover the suit. Thus we can assume its mission is complete and it was destroyed.

So that theory has been retired – and that brings this week’s theory massacre to an end! Now let’s jump into the list of theories I have as we approach the final two episodes of the season.

Number 1: The “monster” is the real Su’kal.

Is this the real Su’kal?

The “monster” which inhabits Su’kal’s holo-world is interesting. Why would his mother or the other Kelpiens programme such a creature? Yes it’s a legend from Kaminar, but to create a holographic monster in a programme designed for a child? They may not have had long to build the programme – which explains the basic nature of some of the other holograms – so why go to all the trouble of creating this one? And why doesn’t it flicker or glow in the same manner as the others, nor seem to have degraded over time?

My theory is that the so-called “monster” – which has a Kelpien appearance – is the real Su’kal; old, decrepit, and badly mutated by a lifetime of radiation exposure that can supposedly kill within hours. The “monster” did not behave like a hologram, did not appear like the other holograms, and when Burnham encountered it it seemed to regard her with an almost-human curiousity.

Add into the mix that Su’kal appears to be far too young to have been present when the Burn occurred – 120-125 years earlier – and I think we have a solid theory.

Number 2: The “monster” is Dr Issa.

The “monster.”

Another possibility for the true identity of the “monster” is Dr Issa, Su’kal’s mother. Though age is again a problem, if Kelpiens post-vahar’ai are especially long-lived she may have survived this long, but without the same level of protection from the radiation she may have mutated and been burned by it. The question of Dr Issa is interesting – was she just a basic plot device; a lure to drag Saru to the nebula? Or is there more to this character than a fraction of a distress call and her son?

The “monster” is one of the most interesting elements to come out of Su’kal, in my opinion, and there seem to be clues that all may not be as it seems. Obviously this theory and the one above can’t both be right – but even if neither are true, there could be more to the “monster” than we expect.

Number 3: Saru is going to die.

Saru in his human disguise.

This isn’t the first time I’ve theorised about a character’s death or departure this season – and so far no such event has come to pass! But as Burnham told us, Saru is “emotionally compromised” by the presence of Su’kal and Kelpiens, and is not thinking clearly. By the way, Burnham calling out someone else for jeopardising the mission and acting impulsively? That’s some top-tier hypocrisy right there!

But we’re off topic. Saru is torn between his almost paternal desire to help Su’kal and find out about Dr Issa and his duty to Discovery. He opted to remain behind aboard the Kelpien ship, and while I doubt he and Culber will simply succumb to radiation exposure, I’m beginning to wonder if this turnaround in his character from the level-headed captain to a risk-taker and mistake-maker will lead to him meeting an unjust end.

Perhaps this is the reason for the odd (and nonsensical within the story) decision to have Saru appear out of costume – to allow Doug Jones to have a more epic death scene? Time will tell.

Number 3A: Burnham will assume the captaincy of Discovery.

Burnham in temporary command of Discovery earlier in the season.

If Saru is killed – however that may come to pass – there will once again be a vacancy in the captain’s chair. Tilly as first officer always felt like a temporary thing, as indeed Saru himself explained when he offered her the role, and after losing the ship to Osyraa so easily there’s absolutely no way she could retain the captaincy – or even the XO position.

That would leave the captain’s chair empty with no obvious replacement. Senior officers such as Stamets or bridge crew like Nilsson or Bryce don’t seem plausible for story reasons, and with Discovery being such a Burnham-centric series, she feels like the only option. Well, unless the plan is to bring in yet another new character!

Number 4: Admiral Vance is going to be killed.

Admiral Vance.

With Osyraa targeting Starfleet, Admiral Vance is the man to lead the fight. I noted an air of finality in his words to Saru in Terra Firma, Part I, and while he has survived thus far, he’s about to face his biggest confrontation.

The conflict with Osyraa and the Emerald Chain has rumbled in the background for more than half of the season, but this is the moment where it has come to the fore. Osyraa already feels like a flat, one-dimensional villain, one who went from easily-beaten to overpowered in the span of a couple of episodes. One saving grace – from a narrative point of view, at least – for the Emerald Chain storyline would be to see a significant character killed.

It certainly could be Saru, as noted above. Or we could see a named secondary character like Detmer or Bryce killed. But Admiral Vance is someone we’ve spent a certain amount of time with this season, and if the writers saw fit to kill off a significant character – but not one of the main crew – he is pretty much the only available target whose death would feel impactful. In that sense, Vance could fill a role played by Admiral Cornwell in Season 2.

Number 4A: Saru will become an Admiral, and Burnham will become captain of Discovery.

Vance, Saru, and Burnham.

If Vance is killed and Saru survives, the question of leadership within Starfleet will arise. Though I would argue that Saru’s recent mistakes – including entrusting Discovery to a first-year ensign – count against him, for story reasons he may be offered a promotion. Earlier in the season he demonstrated his diplomatic skill – with Earth, Ni’Var, and so on – and is arguably well-placed to help the Federation rebuild and begin to come back together.

If he departs Discovery to head up Starfleet, the captaincy of the ship is once again open. And for the reasons listed above, Burnham seems to be the only real candidate.

As I’ve said in the past, Burnham assuming command feels like a goal Discovery has been trying to reach since Season 1. Perhaps this could be the moment it gets there.

Number 5: Tilly will resign as first officer and Burnham will return to the position.

Tilly regards the captain’s chair.

I think it’s a given that Tilly will not be first officer when the ship is retaken from Osyraa – and it will be, obviously. That’s part of the reason why these stories annoy me; I’ve seen enough “the heroes’ ship has been captured!” stories to know what comes next. But we’re off topic!

Rather than Saru or Vance forcibly demoting her, I think Tilly handing the position back is the most likely outcome. It feels as though her arc over these few episodes will be to recognise her own lack of experience and unsuitability for command. She may grow into that role in the future – and perhaps Captain Tilly will be a Star Trek series in a few years’ time! But right now she clearly isn’t the right fit.

If Saru survives and remains in command – which he very well may, it has to be said – that would open up the first officer’s position. Burnham is again the logical candidate, despite the broken trust between her and Saru. She advised him to remain with Su’kal, speaking honestly to him in that moment, and perhaps he will recognise that and reward her for it. Now that she seems to have put her doubts about her role in Starfleet aside, she would be a good first officer.

Number 6: Zora will help the crew retake the ship or protect them from Osyraa’s forces.

Saru talked with Zora in Forget Me Not.

Aside from a tie-in with Calypso, which is interesting in itself, I’m wondering why we’ve seen the Zora AI feature in the season so far. Is it just to connect to that Short Treks episode, or is there something more?

Zora is a combination of the Sphere data and Discovery’s computer, and one of its primary goals – which has been stated as recently as Terra Firma, Part I – is to protect the crew. With the ship having been attacked and conquered by Osyraa, will Zora simply let that slide? Will Zora trust the Sphere data to Osyraa, or will it/she fight back, helping the crew retake the ship?

I suspect it may be the latter, though perhaps Zora will take some persuading. If she is on the side of Tilly and the crew, she might help Burnham and Book get aboard, she might save lives, or even turn Discovery itself against the Emerald Chain, using things like artificial gravity and the environmental controls against Osyraa’s forces.

Number 7: Saru, Burnham, or somebody else will use the Guardian of Forever to send the USS Discovery back in time.

Georgiou used the Guardian of Forever to travel through time.

Assuming that the Red Angel suit is truly gone, and that no one is violating the ban on time travel, the Guardian of Forever is the only way to travel through time that we know of in the 32nd Century. While I can see no pressing need to send Discovery back in time at this juncture, if such a need arose, the Guardian of Forever is about the only option for doing so.

I wrote in my review of Su’kal that the route to the end of the season feels “formulaic” – defeat the Emerald Chain, save or neutralise Su’kal to prevent a reoccurrence of the Burn, and use the dilithium planet in the Verubin Nebula to power the Federation, giving it the (literal and figurative) fuel to bring wayward planets back into the fold. But perhaps I’m wrong – there could be major twists and turns in store.

At the beginning of the season, the main reason for Discovery travelling through time would have been to warn Starfleet about the Burn to prevent it from happening. That possibility still technically exists, but as we’ll discuss in a moment I don’t feel that would necessarily be the right way to go. However, even though I can’t foresee a reason why, it’s possible Discovery will need to go back in time, and the Guardian of Forever could help with that.

Number 8: Dr Issa is a descendant of Saru’s sister Siranna.

Dr Issa.

The actress who played Dr Issa, Hannah Spear, also played Saru’s sister Siranna in Short Treks and in Season 2. Why bring her back to play a different Kelpien – especially considering they look identical? My guess is that there is a familial connection there – Dr Issa may be a distant descendant of Siranna.

Though Saru was – for some reason – reluctant to share this information, the glowing patches seen on Dr Issa indicated pregnancy. Is this a trait all Kelpiens have? If so, why cover it up from the crew? Perhaps the answer is that the glowing patches are something only some Kelpiens have – such as those in Saru’s family. That could be how he knew what the glowing spots meant, and why he didn’t volunteer that information sooner.

I should note that it remains a distant possibility that Dr Issa and Siranna are meant to literally be the same character; that somehow, post vahar’ai Kelpiens live very long, or for some other as-yet-unknown reason. But I think a family connection is more likely.

Number 9: The dilithium planet will be destroyed.

The dilithium planet.

The dilithium planet reminded me at least a little of the Genesis planet in Star Trek III: The Search for Spock. That planet was similarly dangerous and unstable, and was ultimately destroyed. Could the dilithium planet in the Verubin Nebula share its fate?

The main reason why I consider this theory at least plausible is that it would be a major twist on the expected end to the season. Rather than the ridiculous amount of dilithium being used to restore the Federation, it would instead be destroyed, leaving the post-Burn galaxy still with limited travel options.

This in turn could set the stage for Discovery’s Spore Drive being duplicated and rolled out across the fleet – a theory we’ll look at in a moment.

Number 10: Discovery Season 3 is taking place in an alternate timeline or parallel universe.

The Enterprise-C in Yesterday’s Enterprise.

After the Guardian of Forever’s definitive statement on the issue in Terra Firma, it now seems all but certain that Discovery Season 3 is in the Prime universe – the same one as every Star Trek production from Enterprise to Picard. However, it’s still at least possible that, due to time travel or for some other reason, the Burn was not “supposed” to happen.

Thus the ultimate solution to the Burn and the storyline of the season may be to go back to before Su’kal’s ship entered the Verubin Nebula and prevent that from ever happening, wiping this timeline from existence and restoring the “true” timeline.

I don’t believe this would be a good way to go. As a one-off story, an episode set in a timeline that is ultimately overwritten can work. We can look at episodes like Timeless from Voyager or Yesterday’s Enterprise from The Next Generation. But to wipe away the vast majority of an entire season, including presumably characters like Book and Vance, just feels like too much. It would render much of what the crew did – like helping the peoples of Earth, Trill, and Ni’Var – meaningless, and while it would set up another “blank slate” in time for Season 4, I’d rather see Discovery build on this season’s successes. Even if Discovery and her crew remembered what happened, wiping it all out feels like a bad way to go – but one that’s still possible.

Number 11: The Burn was a superweapon – perhaps one the Federation or Section 31 built.

Is Su’kal the cause of the Burn? If so, is he the sole cause?

Is the reason for Su’kal’s power really just technobabble about radiation exposure in the womb? Or is there more to it than that?

We’ve seen in past Star Trek shows stories about genetic enhancements and shadowy organisations exploiting and weaponising the unique abilities of people. Could there be another dimension to Su’kal? Perhaps he quite literally is a weapon, one designed for this very purpose – to attack the Federation’s enemies (or the Federation) through a coordinated attack on dilithium.

Though it seems like Su’kal is indeed the source of the Burn, another source may be revealed, absolving him of blame. I noted that his “scream” did not actually cause a second Burn – even though characters feared it came close – so perhaps there’s something else at play here that we don’t yet know. That other factor could be this superweapon – and it may be designed to target the Federation’s enemies, like the Borg.

Number 12: There will be a resolution to the story of Calypso (the Short Treks episode).

Craft, the protagonist of Calypso.

The main point from Calypso which is still unresolved is how Discovery ended up in a nebula abandoned. And if, as has been hinted through the use of the term V’draysh, Calypso takes place sometime around the 32nd Century, how did the ship end up back in time?

The Verubin Nebula initially seemed to offer a partial explanation, but not only was Discovery not present there, the nebula itself is very different to the one inhabited by Zora, so that option seems to be off the table.

I have no clue how this circle will be squared – but it’s still possible that it will be, especially given how much progress we’ve seen toward unpicking the mysteries of Calypso this season.

Number 13: The Spore Drive will become Starfleet’s new method of faster-than-light propulsion.

Tilly and Stamets by the Spore Cube.

As mentioned, the end of the season from here could have already been telegraphed: retake the ship, save/neutralise Su’kal, and use the dilithium planet to bring the Federation back together. But that may not be the way the story ends.

As mentioned, the dilithium planet could be destroyed – perhaps to prevent another Burn, perhaps to save it from falling into Osyraa’s hands, or perhaps even accidentally either by Su’kal or someone else. If it’s gone or rendered unusable somehow, we’re back to the Spore Drive as a potential way to give Starfleet faster-than-light capabilities.

Doing so would finally find a use for Discovery’s most controversial piece of technology, and would potentially open up whole new regions of space for exploration. The Federation, despite having almost eight centuries to expand, appears to have mainly been an Alpha Quadrant power even before the Burn. Did they ever revisit the Delta Quadrant, for example? Did the Burn reach that far? Perhaps future Star Trek shows could be set in this time period and could follow the adventures of a new crew aboard a new Spore Drive-powered ship, exploring the galaxy. It would also set the stage for Season 4.

Number 14: A character from a past iteration of Star Trek – such as the Doctor from Star Trek: Voyager – will make an appearance.

Tom Paris with The Doctor in Star Trek: Voyager.

As time drags on with no appearances, I’m beginning to think that the only way this theory – which I posited before the season premiered – could come true is as a kind of epilogue or coda after the main storylines have concluded; perhaps even as a tease to the events of Season 4. It would certainly be difficult – but not impossible – to bring back a major character from Star Trek’s past at this juncture, given the complicated nature of the story overall. Given that there’s also no clear way that a returning character could have an impact on the story without that impact seeming to come from nowhere, perhaps we won’t see any significant character crossovers this season.

However, it remains a possibility. The Doctor is one character who fits the bill, but there are others who could reasonably have survived this long. And as I mentioned several times already, all it would take to bring back practically anyone is a technobabble explanation for how they were in stasis or travelled through time.

Having seen a tie-in with Picard via the appearance of the Qowat Milat, and the aforementioned Guardian of Forever return from The Original Series, it gives me hope that Discovery will find more ways to tie itself to the wider Star Trek franchise. A character crossover is a spectacular way of doing that, and as The Next Generation showed with episodes like Relics, the passage of centuries is no barrier to such a crossover in a sci-fi world. Until the credits roll on the season finale, I’ll keep advocating this theory!

Number 15: The ships at Federation HQ represent the majority of Starfleet’s remaining vessels. And they’re all 120+ years old.

A portion of the fleet docked at Federation HQ.

I’ve been suggesting for several weeks that the rump Federation may only have a handful of ships available – with scarce dilithium for fuel, there is no way to maintain a huge armada, even if the ships were undamaged. It also seems reasonable to assume that Starfleet’s shipbuilding facilites were damaged or destroyed in the Burn, and that building new ships has been difficult – if not impossible for the fractured organisation – ever since.

With Osyraa now on the warpath, we could finally see whether Starfleet has an ace up its sleeve. Are there more ships beyond those few docked at HQ (and the two Mr Sahil noted)? And those ships may very well be old – they seemed new and futuristic to Discovery’s crew, but that could all be pre-Burn technology, meaning that Osyraa has the upper hand if the Emerald Chain has developed new weapons and technologies. We saw in People of Earth that quantum torpedoes were still in use, for example. Does Osyraa have a more powerful fleet?

Number 16: The Dax symbiont is still alive.

Jadzia Dax in Deep Space Nine.

This one is looking increasingly unlikely, because the two locations where Dax could have appeared have both seemingly come and gone without them: most notably the Trill homeworld in Forget Me Not, but also Federation HQ in Die Trying. However, there are hints at a lifespan for Trill symbionts that may be exceptionally long, in which case Dax could very well still be alive in the 32nd Century.

Obviously we won’t see Ezri Dax (barring some bizarre time travel/stasis storyline) but the symbiont itself could have lived this long. When Adira “met” the Tal symbiont’s former hosts in Forget Me Not, one was wearing a Star Trek: Picard-era uniform, hinting that Tal may have lived 700+ years. There are production-side explanations for this Easter egg, and as stated the fact that two of the best opportunities so far to meet Dax have come and gone most likely means it won’t happen this season. But I’m sticking to my guns on this one: Dax is alive!

Number 17: The ban on time travel is being flouted – possibly by secretive elements within the Federation.

Kirk’s stolen Bird-of-Prey travels through time in The Voyage Home.

Admiral Vance clearly believes that the ban on time travel is intact and being followed. Kovich indicated that he does too – but I’m not sure how far I trust him. Is he an agent of Section 31?

It’s impossible to un-invent a powerful, useful, weaponisable technology, no matter how hard you try. Considering how crappy the 32nd Century seems to be, are we convinced that nobody at all is using time travel to try to give themselves an advantage? Not the Dominion? Not the Borg? Not Section 31? Seems unlikely to me, though for production-side reasons of wanting to keep the timeline intact and to avoid overcomplicating the plot we might be told this is true.

Number 18: Kovich is an agent of Section 31.

Who does Kovich work for?

Who is Kovich? He doesn’t wear a normal Starfleet uniform, and doesn’t appear to hold a Starfleet rank. Yet he wears a Starfleet combadge and is clearly a high-ranking intelligence officer as he undertook Georgiou’s debriefing and has access to classified files that pertain to time travel and parallel universes.

It is at least possible – if not outright likely – that this mysterious character works for Section 31. Since we now know he hasn’t just disappeared and may well be coming back, perhaps we’ll learn more about him. We know he has an interest in the Mirror Universe and Terran society, expressing almost an admiration for Georgiou and her way of doing things.

It seems less and less likely that Section 31 or Starfleet are connected to the Burn – but as noted above, it remains a possibility. Perhaps Kovich knows more about the Burn that he let on?

Number 19: We haven’t seen the last of Zareh.

Zareh in Far From Home – his only appearance to date.

After weeks of suggesting Zareh could return, I half-expected to see him beaming aboard Discovery with Osyraa’s forces. Though we didn’t see him in the first wave, he may yet prove to be among her troops, and if he is he may wish to seek revenge against Tilly and Saru for abandoning him. These kinds of characters have a tendency to pop back up, and although leaving him alone on the surface of the Colony back in Far From Home was described as a “death sentence,” the fact that we never saw him die means his fate is unclear. If he survived, would Osyraa even want him back? Maybe.

So that’s it. Despite losing a number of theories this week, we also added several new ones! They aren’t all going to be right, of course – perhaps none will be – but one thing is for sure: Su’kal shook things up in a major way after several weeks where the series made scant progress on its main storyline and attended to side-missions.

Despite what I’ve said about the road to the season finale seeming to be obvious, there are undoubtedly going to be at least some unexpected moments along the way. I’m hoping that will be the case, actually, because I love being surprised! I’m also not 100% convinced that Discovery has got the right story if I’m correct about the direction of travel. The journey may still be fun – as indeed Su’kal was for the most part – but it may end with a less-than-satisfying explanation for the season’s big arcs.

Let’s hope not, though!

Please remember that these theories are just a bit of fun. Some may seem plausible – or even highly likely – but that doesn’t mean that this is the way the story will unfold. I’m just a guy with a website, I’m not claiming to have any “insider information,” nor am I saying that the theories postulated above will come true. No fan theory is worth getting so invested in that the actual story becomes disappointing or upsetting. Personally, as much as I love feeling like I predicted something that later appeared on screen, I also truly love being surprised by Star Trek and other franchises. That doesn’t mean writers should make silly or arbitrary decisions purely for shock value, but it does mean that when a theory of mine falls flat on its face, far from getting upset I revel in that. If we could all remember to take fan theories with a healthy pinch of salt, maybe there’d be a little less toxicity in certain areas of the fandom.
