Spoiler Warning: There are spoilers ahead for Star Trek: Discovery Seasons 1-3, Star Trek: Picard, and other iterations of the franchise.
Star Trek: Discovery Season 3 came to an end this week. That Hope Is You, Part 2 was a solid episode with plenty of action, and despite the underwhelming nature of one of its plotlines, I think it did a good job wrapping things up.
Speaking of wrapping things up, that’s what we’re going to do today! We had twenty-two theories going into the finale, and while a handful live on and may return in Season 4 depending on the way things go, most were either outright debunked or the story went in such a direction as to leave them looking very unlikely. We did, however, get three confirmations (or at least partial confirmations) so we’ll look at those first!
Confirmed theory: Aurellio stood up to Osyraa.
Although Aurellio didn’t get as much screen time as I’d have liked to see, he did break away from Osyraa and the Emerald Chain. Aurellio had a mini character arc that ran over the final two episodes of the season in which his eyes were opened to Osyraa’s villainous nature, and allowed him his moment of opposition to her when he refused to allow his technology to be used to torture Book.
I stand by my previous comparison in which I said that Aurellio fills a role claimed by the likes of Albert Speer and others who worked for the Nazis during the 1930s and 1940s. Aurellio seems to have spent a lot of time focusing on his work in his lab, reaping the rewards of helping the Emerald Chain but without really allowing himself to see what the organisation and its leader were doing. His conversation with Stamets opened his eyes to this, and we saw that theme come to a head in the scene in sickbay.
Though Aurellio did briefly help out later on, giving Book the idea that he could use his empathic abilities to use the Spore Drive, Aurellio feels like an underused character, and I hope to see him return in Season 4. He could have joined up with the Federation, or even serve aboard Discovery.
Part-confirmed theory #1: Burnham became captain.
I successfully predicted that Burnham would become captain… but not how it would happen! So I’m calling this one part-confirmed instead of fully confirmed!
I had speculated that Burnham could assume the captaincy either because Saru would be killed, or because Saru would be promoted and become an Admiral if Admiral Vance were killed. Neither of these scenarios came to pass, and Saru was rather unceremoniously shuffled off the ship during the epilogue without getting so much as an opportunity to say goodbye to the crew. That was poor, and Saru deserved to be treated with more respect.
However, it allowed Burnham to get her promotion, something that Star Trek: Discovery has been aiming for since Season 1. Some of the issues with Burnham, both this season and in the past, stem from her insubordination. Now that she’s in command, that should no longer be anywhere near as big an issue, and as captain she should have a lot more freedom to approach problems and adventures her way – within the spirit of the rules, if not following them to the exact letter!
Part-confirmed theory#2: The Federation’s allies arrived to help fight the Emerald Chain.
I’m calling this one part-confirmed because only Ni’Var arrived to help the Federation when the Emerald Chain attacked. I had half-expected a bigger fleet, perhaps comprised of the Earth Defence Force, the raiders from Titan, the Trill, people from the Colony, people from Kwejian, and Nhan aboard the USS Tikhov. However, only Ni’Var made it to the party!
We don’t know what became of most of the others; Trill rejoined the Federation, but the rest weren’t even mentioned in the finale. The arrival of the Ni’Var fleet felt great – up there with other big last-minute arrivals in other battles in the franchise for sure. But by the end of the episode I did feel that the absence of some of the other friends and allies that Burnham and the crew had made was noticeable… and perhaps even a little sad.
So those theories were confirmed or partially-confirmed. Up next we have a handful of theories whose status was left unclear as of the end of That Hope Is You, Part 2. It’s possible some of these will return in Season 4, but it depends how the story of that season shapes up. If Season 4 goes in a completely different direction, perhaps some or all of these theories will simply fall by the wayside. We most likely won’t know for a while!
Status: Unknown #1: The Spore Drive will become Starfleet’s new method of faster-than-light propulsion.
The revelation that Book could use his empathic abilities to use the Spore Drive has, in theory, opened up the technology to being deployed across other Starfleet vessels. Early in Season 1 Stamets seemed to suggest that mycelial spores were not easy to acquire, so that may yet prove to be a limiting factor, but if that could be overcome there’s no real reason why the Spore Drive couldn’t be rolled out.
If empathic species like the natives of Kwejian can use the Spore Drive, it opens up even more possibilities. Betazoids spring to mind as an empathic species; perhaps they could become navigators too.
As this moment came in the final act of the season finale it didn’t get a chance to be paid off, so we won’t know the status of the Spore Drive until next season at the earliest. When Burnham was in command of the ship right at the end of the episode, her orders were to deliver dilithium to other planets, so perhaps we can infer from that that not every vessel will have its own Spore Drive. Regardless, the expansion of this technology would not only allow Discovery to have new and different adventures, but would also make it so other Star Trek series set in or after this time period could do so too.
Status: Unknown #2: The Dax symbiont is still alive.
On reflection, this theory should have been put on hiatus as soon as Discovery departed the Trill homeworld in Forget Me Not. But I stand by the reasoning behind it – Trill symbionts can be very long-lived, and we got at least a hint at Tal having been alive in the 25th Century via the appearance of a Picard-era uniform. Though Dax had already had several hosts by the time of Deep Space Nine, nothing in-universe would prevent their reappearance.
However, with the Trill having rejoined the Federation, perhaps there will be an opportunity to see or hear about Dax in Season 4.
Status: Unknown #3: Kovich is an agent of Section 31.
Kovich made only a very brief appearance in That Hope Is You, Part 2, so we didn’t get an opportunity to learn anything more about him. It was implied that he has a role in Starfleet security and/or intelligence based on his debrief of Georgiou and ability to access classified files. Combined with his morally ambiguous personality – which we see on full display when he doesn’t tell anyone about Georgiou’s impending health emergency – it doesn’t seem unreasonable to assume he could be an agent of Section 31… or even its leader.
Given Georgiou’s connection to the upcoming Section 31 series, and the time travel plot to get her there, perhaps the reason Kovich didn’t say anything is because he knew exactly what role he needed to play. Georgiou, as a leader in Section 31 centuries earlier, may have sent him a message through the organisation, telling him exactly what to do when she arrived. That would be a time-loop story that we could see in Season 4!
We know Kovich will be back, so perhaps we’ll learn more about him when he returns. I’ve heard other Trekkies speculating that he could be the Federation President – that would be an interesting revelation too.
Status: Unknown #4: The ban on time travel is being flouted – possibly by secretive elements within the Federation.
It was stated multiple times in Season 3 that there is a galaxy-wide ban on time travel, a ban which was brought in in the aftermath of the Temporal Wars. However, this never sat right with me for one simple reason. As I’ve said several times over the last few weeks: it’s not possible to un-invent an incredibly powerful, weaponisable technology.
Even if the ban on time travel had been adhered to prior to the Burn, it seems completely implausible that absolutely nobody would seek to revive time travel technology in the century that followed. The Emerald Chain are the main villainous faction we met in Season 3, and Osyraa seems like she would have put people like Aurellio to work on re-inventing the necessary technology. But even if the Emerald Chain were unable to use time travel, what about other factions like the Borg or the Dominion? And what about Starfleet itself, and Section 31?
Finally, assuming all of the factions mentioned have agreed to adhere to the ban, who’s enforcing it to make sure they all stick to their commitments? Communication across the galaxy is incredibly difficult, so how can any of the main factions be sure that their adversaries – or even rogue elements from within – aren’t trying to use time travel?
I find the whole idea of the ban impractical unless it can be properly explained how time travel was banned and how the ban is enforced. So I maintain that, despite what we saw all season long, there may be elements within the Federation working on covert time travel projects.
Status: Unknown #5: The ships at Federation HQ represent the majority of Starfleet’s remaining vessels. And they’re all 120+ years old.
When Discovery first arrived at Federation HQ in Die Trying, I theorised that the ships we saw might be all that remain of the once-mighty Starfleet. In addition, the devastating nature of the Burn may well have meant that building new ships would be difficult – and with very little dilithium to power them anyway, Starfleet may be forced to rely on a fleet of ageing vessels.
We saw no confirmation of this – and to Discovery’s crew, all the ships look futuristic and new! But we saw nothing to debunk it either, and while I don’t think we’ll see this point explicitly addressed any time soon, we may learn in Season 4 that the fleet is being rebuilt and expanded.
Status: Unknown #6: Tilly’s role as first officer.
I had theorised that Tilly would resign as first officer in the aftermath of the ship being captured. However, as of the end of the season it was left ambiguous as to what happened. Did Captain Burnham keep her on, or will she choose a new XO?
Tilly becoming first officer was a contentious point for some fans, and while I do understand why, I wasn’t upset by it personally. I’d be happy to see her remain in her post if that’s what the writers and producers have in mind, but equally I’d be happy to see a different character take on the role. Perhaps someone like Bryce, Rhys, or Nilsson could be promoted – and join the regular cast?
So those theories’ fates remain unknown. Will they be confirmed or debunked next season, or in some other future Star Trek story? It’s possible, but it’s equally possible that some of them will simply be ignored and their status never addressed.
Next we’ll look at a couple of theories which, while not explicitly debunked, are now certainly dead as the storylines they were part of have concluded.
Dead theory #1: Dr Issa is a descendant of Saru’s sister Siranna.
Dr Issa’s potential family connection to Saru was not addressed, and I think it’s highly unlikely it will be mentioned in Season 4. The reason for this theory was primarily production side, as the same actress (Hannah Spear) played the role of both Siranna in Season 2 and Dr Issa in Season 3. As interesting as it would have been for there to be a deeper connection between Saru, Dr Issa, and Su’Kal, the explanation for this may also be on the production side of things – it may have been easier to bring back an actress who was already fitted for the complicated Kelpien prosthetic makeup rather than casting someone wholly new.
Dead theory #2: Aurellio is married to Osyraa.
There seemed to be a hint that Aurellio was married to or in a relationship with Osyraa. Stamets noted that his partner, with whom he is said to have children, is Orion – and Osyraa seems to be Orion too. They also had a familiarity that seemed to go beyond employer and employee, as well as a history that Aurellio hinted at in his conversation with Stamets.
Osyraa attacked him in That Hope Is You, Part 2, but despite threatening to kill him, took no further aggressive action. However, now that she’s dead and the Emerald Chain has “fractured,” I doubt we’ll hear much at all about Osyraa in Season 4 even if Aurellio does return (as I hope he will).
So those two theories seem certain to be dead and not coming back, even though they were not out-and-out debunked.
Finally we come to the debunkings!
Debunked theory #1: One of the officers with Tilly will be killed.
At the end of There Is A Tide, Tilly gave the ominous order to her team that if anyone should be killed, the rest would keep going until they reached the bridge. Then in That Hope Is You, Part 2, the whole group were suffering from oxygen depletion as Osyraa tried to slowly suffocate them.
Owosekun was perhaps in greatest danger as she took their makeshift bomb to the nacelle, but she was saved at the last minute by a DOT 23 – who was in turn saved by Owosekun and Reno in the epilogue.
Ryn was the only major character on the heroes’ side who died across the whole season, and we can argue whether or not that’s a good thing at a later date. But in the context of this theory, everyone survived so the theory is debunked!
Debunked theory #2: The Burn will receive a different explanation.
At some point in the next few weeks or months I will take an in-depth look at the Burn – Season 3’s most controversial storyline. For now, however, suffice to say that this point was more a last-ditch hope than a theory, as I felt certain that if the Burn remained solely the fault of Su’Kal it would be underwhelming.
That explanation, which was first communicated in Su’Kal a couple of weeks ago, ended up being accurate. There was no deus ex machina in the season finale to re-explain what the Burn was and how it happened – and that’s probably a good thing overall. Though the Burn was – in my subjective opinion – a narrative that didn’t come to a satisfactory end, and one that has issues, a last-second deus ex machina would have been even worse!
Debunked theory #3: The Burn was the result of a superweapon.
After the rest of my pre-season theories about the Burn fell by the wayside, this was the final one that I considered to be even slightly possible. Going into the finale, the way it could’ve worked would either be that the Kih’eth (Su’Kal’s ship) was carrying a superweapon, or that Su’Kal himself had been modified somehow to become a superweapon. How or why this would’ve happened is not even relevant; it was just a way to explain the Burn beyond Su’Kal.
As mentioned above, though, the Burn turned out to be caused by Su’Kal and his connection to dilithium. In the context of the last few episodes this was a good thing, as a last-second turnaround would have been very difficult to pull off.
Debunked theory #4: There will be a resolution to the story of Calypso (the Short Treks episode).
Season 3 spent some of its runtime firmly establishing that the Short Treks episode Calypso hasn’t been forgotten and remains very much in play in the overall storyline of Discovery. However, despite several teases and moments that seemed to inch us closer to resolving the mysterious outlying episode, there was no resolution.
We have seen the creation of Zora – a merger of the Sphere data with Discovery’s own computer. We heard that some denizens of the galaxy call the Federation the “V’draysh,” which was the name Craft used in Calypso. The main unresolved point is how the USS Discovery came to be abandoned, and why, if it was abandoned, it was reset to its pre-refit configuration beforehand.
With Zora being intact thanks to Reno and Owosekun, we have all of the threads present in Calypso – but I can’t see how they’ll tie together just yet. Maybe Calypso is set in the far future – the 42nd Century not the 32nd. Maybe Discovery will travel back in time in Season 4 or Season 5 for some reason. Maybe Calypso will never be fully explained and will remain an outlier in the Star Trek canon; an episode connected to a storyline for Season 2 or Season 3 that simply never came to pass.
Debunked theory #5: A character from a past iteration of Star Trek – such as the Doctor from Star Trek: Voyager – will make an appearance.
This was my other big pre-season theory that remained in place for the duration. Though it did come true somewhat thanks to the return of the Guardian of Forever, we didn’t see any of the characters I theorised about – including Voyager’s Doctor – make a return.
However, although it was debunked in Season 3, this one will almost certainly be back for Season 4! When Star Trek: Picard brought back legacy characters, we knew in advance which main actors would be returning, and their presence became a big part of that show’s marketing push. Other legacy characters were recast and their presence was kept more of a secret. In short, what I’m saying is that if we are to see the return of the Doctor or some other past Star Trek character, perhaps their return will be signalled ahead of time in Season 4’s pre-release marketing. We’ll have to wait and see!
Debunked theory #6: Discovery Season 3 is taking place in an alternate timeline or parallel universe.
The Guardian of Forever confirmed back in Terra Firma, Part II that Burnham and the crew were in the Prime timeline – i.e. the main Star Trek timeline which runs from Enterprise to Picard. However, this theory also proposed that the season may be taking place in a timeline that was manipulated by time travel; that the Burn was not “meant” to happen.
Had time travel been involved, the resolution to the Burn and the season’s story may have been to go back in time – perhaps even using the Guardian of Forever – and stop Su’Kal from ever entering the Verubin Nebula, thus preventing the Burn entirely.
I don’t think this would have been a good storyline, as it would have essentially wiped out everything that happened in the season. A one-off episode like Yesterday’s Enterprise from The Next Generation or Voyager’s Year of Hell can get away with doing something like this, but a whole season being erased due to time travel would have felt hollow – even if Discovery’s crew remembered what happened.
Debunked theory #7: Saru is going to die.
Despite being in danger for much of the episode, Saru survived… only to be unceremoniously dumped in voiceover during the epilogue. It has been confirmed that Saru will be back for Season 4; what role he will play, and whether he will even be a major character are unknown.
Saru is a very interesting character. He was, for a time, Star Trek’s first alien captain, and I wish we’d seen more of what that meant. Saru is similar to Picard in many ways – he’s diplomatic, calm, and generally not one to break the rules and rush into a situation guns blazing. Burnham, in contrast, is much closer to Kirk or Janeway – more emotional, impulsive, and quicker to bend the rules.
Both types of captain can work very well, so that isn’t a criticism! If I had one wish from the season finale, it would have been to see Saru receive a proper goodbye from his shipmates.
Debunked theory #8: Admiral Vance is going to die.
When considering characters who could’ve been killed off, aside from the main crew of Discovery few deaths would have been as impactful as Vance’s. I didn’t want to see him killed, of course, because he’s been one of Star Trek’s most interesting flag officers. The role of Admiral has often been used within the franchise to set up an antagonist for our hero captains to rebel against. Vance is one of the good ones, and I’m glad he survived.
Hopefully he will continue in this role in Season 4, because there’s a lot of potential for some fun character moments.
Debunked theory #9: Saru, Burnham, or somebody else will use the Guardian of Forever to send the USS Discovery back in time.
This was primarily connected to my theory about a resolution to Calypso – which seems to require the USS Discovery being sent back in time. If the ban on time travel discussed above is truly in effect, the Guardian of Forever is the only way we know of to travel back in time, and having gone to the trouble of bringing the Guardian back, I wondered if it might serve more of a purpose than just sending Georgiou back in time.
It turned out that this was not the case, though I hope the Guardian of Forever will be visited again in some future episode or story.
Debunked theory #10: The dilithium planet will be destroyed.
This theory came about as a way that the “formulaic” end to the story could be subverted. Rather than the dilithium planet being a resource for the Federation to use to re-establish itself, its destruction would mean that the Burn’s impact would continue to be felt, and that the task of coming back together would be more difficult.
It would have also connected to my theory that the Spore Drive would be rolled out to more starships, becoming Starfleet’s new method of propulsion. The lack of dilithium would make that almost a necessity! I theorised that Su’Kal might’ve destroyed the dilithium planet via his telepathic abilities, but it could also have been destroyed by Osyraa or even by the Federation to prevent Osyraa from using it.
None of that came to pass, however, and the dilithium on the planet is being mined by the Federation and distributed to their worlds, colonies, and allies across the galaxy – a task that Burnham and the ship are assigned to in the final moments of That Hope Is You, Part 2.
Debunked theory #11: The “monster” is the real Su’kal.
The “monster’s” presence within Su’Kal’s holo-programme was not really given an explanation beyond it being part of an old Kelpien legend. Why his mother would have chosen to include a lifelike recreation of the “monster” within the programme is anyone’s guess!
I theorised that the character we met may not have been the real Su’Kal, and that the “monster” may have instead been Su’Kal, who had been badly mutated and burned by radiation. When Burnham briefly interacted with it, the “monster” seemed to behave in an almost-human way, and that was another reason I considered this a possibility.
Debunked theory #12: The “monster” is Dr Issa.
As above, I speculated that the “monster” may in fact be a real person – this time Su’Kal’s mother, Dr Issa.
In the end, it seems that the “monster” was simply a part of the programme. It provided a great reason within the story for Su’Kal and Saru to bond, as well as a way to give Su’Kal an arc of his own, overcoming his fears – represented by the “monster” – to break free of the programme. I’m not sure how much sense it makes for the “monster” to have been programmed when considering it from an in-universe point of view… but that’s more of a nitpick than anything.
So that’s it. A few theories remain unanswered, and may roll over to Season 4 – but it depends on what route the next season’s story will take. We won’t have any indication of that until we see a trailer or receive a significant announcement, but I’ll be keeping my ear to the ground to see what happens over the coming weeks and months.
When might we see Season 4? That’s perhaps the biggest question on the minds of Trekkies and Discovery fans! We know that pre-production began weeks ago, and that filming of some scenes has already commenced in Canada. Because the pandemic remains a significant disruptive force, it’s possible that filming will proceed at a slower pace than usual. June 2021 seems to be the target date for filming to finish, and if that happens then post-production work will begin in earnest this summer. Based on how long post-production took for Season 3, it seems incredibly unlikely that we’ll see the show before next year, and I would say that spring 2022 seems a reasonable guesstimate at this juncture.
With other live-action Star Trek projects similarly impacted, it doesn’t seem likely that we’ll see Picard, Strange New Worlds, or the Section 31 series this year either – but there’s hope for Lower Decks Season 2 and Prodigy to be broadcast before Christmas; both of those animated shows are already in production.
Stay tuned, because if and when we hear news of Season 4 or get a trailer I’ll be sure to break it down and perhaps see if any theories can be conjured up! I’ll also be doing a look back at some of my hits and misses from a theory point of view later this year, and a retrospective of the season overall sometime soon too. There will be plenty more Star Trek content to come on the website this year, so I hope you’ll come back to see some of that. Finally, I hope that you enjoyed following my theories and predictions this season. I had a lot of fun spending time in the Star Trek universe, diving deeply into some weird and wonderful ideas!
As I always say, these are just theories. I don’t have any “insider information” and I don’t pretend that any theory I postulate is going to come true. For me this has just been a bit of fun; a chance to take a deeper dive into some elements of Discovery and the Star Trek universe. I hope you haven’t taken any of my theories across Season 3 too seriously – no fan theory, no matter how plausible it seems, is worth getting upset, angry, or disappointed over. If we could all remember to take theories with a pinch of salt, perhaps there’d be a little less toxicity within certain fan communities.
