Spoiler Warning: There are spoilers ahead for Star Trek: Discovery Seasons 1-4. Spoilers are also present for the following Star Trek productions: Picard Season 2, Voyager, Enterprise, and The Next Generation.
Species Ten-C was a good episode, and while there’s still a lot of story to get through if the season is going to wrap up everything by next week, we’re well on the way to stopping the DMA and saving Earth. This week saw the first major theory cull of the season, with a whopping nine debunked theories. As the season approaches its end, this was to be expected!
We’ve got a lot to get through this time as we whittle down the theory list going into the season finale, so let’s get started by looking at the theories that have been debunked.
Debunked theory #1:
Unknown Species 10-C is a faction from a past iteration of Star Trek.
We’d been moving away from this theory for weeks, and it had been looking increasingly unlikely as Captain Burnham and the crew approached their base of operations. As I said when I first considered the theory, it always felt like there was a good chance that Discovery would go down this route; it happened in Season 2 with Control and the Red Angel, and in Season 3 with the Burn. Tarka’s friend Oros also being a new character was a strong indication that Discovery wants to do its own thing, adding to the lore of Star Trek and expanding the franchise instead of returning to elements and factions from the past.
Still, it was fun to consider the different factions that might’ve been involved! There were some genuinely plausible candidates for creating something on the scale of the DMA – the Borg, the Kelvan Empire, and Enterprise’s Sphere-Builders, to name just three – and I had fun putting together my long list earlier in the season. Thinking about where some of these factions could be by the 32nd Century was also interesting.
At the end of the day, I’m not surprised that Discovery went in this direction. What I would say, though, is that now Unknown Species 10-C has been created, I hope Discovery doesn’t just ignore them in Season 5. The story took a long and winding route to reach this point, and it would be a shame if all we ever see of Unknown Species 10-C comes in two episodes at the end of the current season.
Debunked theory #2:
Unknown Species 10-C is extinct.
This theory would have scrapped the “figuring out how to communicate” angle that was a big part of this week’s episode, and would have replaced it with Captain Burnham and the crew perhaps having to discover how to use some very alien technology to shut down the DMA. When we learned more about Unknown Species 10-C, like their planet having suffered a catastrophe, I felt it was plausible that they were no longer around, with the DMA being a kind of Doomsday Machine-inspired device. There could have been interesting allegories for things like climate change and pollution from such a storyline.
Ultimately, of course, Discovery showed us that Unknown Species 10-C is alive and well, living their best life on three planets inside of their hyperfield. As the season enters its final act, I hope we get to learn much more about this unique civilisation.
Debunked theory #3:
The bones from Rosetta don’t belong to Unknown Species 10-C.
I speculated that the huge bones that the away team found in Rosetta may not actually be from Unknown Species 10-C themselves, and could be from domesticated animals or other creatures that lived on their homeworld. This would have potentially allowed for Unknown Species 10-C to surprise us with their appearance, possibly even being humanoid!
It didn’t turn out that way, though, and although the Unknown Species 10-C representative in Species Ten-C was partially obscured when they made contact with the USS Discovery, they seemed to be the right size and shape for the bones from Rosetta. Also, they used the pheromones that the away team discovered.
Debunked theory #4:
The hyperfield will be empty or abandoned.
This theory could have been connected to the one above, with Unknown Species 10-C being extinct. Or it could have stood on its own, with the hyperfield perhaps serving as a portal or wormhole to a different galaxy or even another dimension. Figuring out where Unknown Species 10-C had gone could have been part of such a story, and maybe Captain Burnham and the crew would have had to leap into the unknown in order to stop the DMA.
As it turned out, the hyperfield had three whole planets inside of it! There were presumably huge numbers of Unknown Species 10-C doing their thing, living their lives and making the hyperfield a thoroughly inhabited place!
Debunked theories #5-8:
Someone else made the DMA.
As of last week, I still had the Red Angel suits from Season 2, Oros, Dr Kovich, and President Rillak on my list of possible culprits, either being directly implicated with the DMA or at least being connected to it in some way. I think we can now strike all of them from the list!
Unknown Species 10-C have clearly never met a human, nor anyone else from within the Milky Way galaxy, as we saw from their inquisitiveness and their initial inability to recognise that the strange creatures they’d encountered were even sentient. If they’d discovered a Red Angel suit or met someone like President Rillak or Oros, Discovery’s initial first contact wouldn’t have unfolded in that way.
Finally, with Tarka now being set up as the villain of the season’s final act, there’s no way to add someone like Dr Kovich or President Rillak into the mix as well. Rillak, despite her Machiavellian qualities, now seems to be firmly established on this side of the story. I think there’s scope to spend more time with her, and perhaps even set up an antagonistic role for her in future, but it now seems certain that it won’t happen this season.
Debunked theory #9:
Captain Burnham will use the interdimensional transporter.
It’s still possible that Tarka will get his interdimensional transporter working – even if doing so comes at the expense of hurting Unknown Species 10-C. However, this theory was set up on the premise that Unknown Species 10-C may be from another dimension themselves, and that using Tarka’s device could be the only way to reach them. That is clearly not the case, so I think we can strike it from the list.
I’d like to see the Tarka-Oros storyline about their interdimensional transporter paid off before the season ends… somehow. It would feel a little hollow if all it turns out to be is a macguffin, something to motivate Tarka to pursue this increasingly unhinged plot to steal Unknown Species 10-C’s power-generating tech. But with only one episode remaining, there’s very little time left to do anything meaningful with this side of the story!
So those theories were debunked!
There are several other theories that are hanging by the thinnest of threads, but I’m going to leave them in place for now. Even if they don’t pan out this season, there’s still scope for some of them to be incorporated into Season 5.
We have a number of theories that are still firmly in play, though, so let’s jump into the list!
Theory #1:
Unknown Species 10-C is connected to a faction from Star Trek’s past.
Although Unknown Species 10-C turned out to be brand-new to the franchise, there’s still scope for them to have some kind of connection with a faction from Star Trek’s past. Most organic factions are probably ruled out thanks to the way Unknown Species 10-C reacted; they’ve clearly never encountered humans, Kelpiens, or Vulcans before! But they could have met someone like the Borg, for example, or the super-synths from Picard Season 1.
This theory is definitely running out of road with only one episode remaining, and if the season finale has to deal with Tarka and the DMA, perhaps we won’t actually get to learn very much at all about Unknown Species 10-C. However, I think a connection remains a possibility – even if it’s a shrinking one!
Theory #2:
Unknown Species 10-C is responsible for the galaxy’s dilithium supply running out.
It seems as though Unknown Species 10-C may not have been aware that the Milky Way is inhabited by sentient beings. If that’s the case, and they’ve somehow managed to be entirely unaware of everyone from the Andorians and Borg to the Xindi and Yridians, it’s possible that they’ve been exploiting the galaxy for resources for a very long time. Season 3 didn’t explain why dilithium was suddenly in short supply, so it could turn out that Unknown Species 10-C stripped away much of the galaxy’s supply in the years before the Burn.
Unknown Species 10-C could have even used a similar mining tool to the DMA to extract dilithium, sending it back to their hyperfield through wormholes. Again, time seems to be running out to explore this idea in much detail – but it would be a fun and interesting way to link the two 32nd Century seasons together!
Theory #3:
Book and Burnham will reconcile and get back together.
Book is in serious danger right now! Trapped aboard his ship with Tarka in control, it’s possible that he won’t survive the season. However, if he does survive I’d very much like to see him and Burnham get back together. The whole “relationship drama” angle was not Season 4’s best narrative choice, and there were other ways to get the main story arcs to this point without disrupting Book and Burnham’s relationship.
However, as of Species Ten-C, Book appears to have moved much closer to Burnham’s position of making peaceful first contact. Partly, it has to be said, this is out of necessity: Tarka’s plan would seemingly destroy the hyperfield, the USS Discovery, Unknown Species 10-C, and would still leave Earth and Ni’Var in danger. But even before the consequences of Tarka’s plan became apparent, Book had moved back in this direction. In Rubicon, we saw how he was willing to pause his plan and wait for diplomacy, so there’s scope for him to fully come back into the fold and reconcile with Burnham.
Though I don’t believe female characters in any way need to have a male character in their life, after Burnham had been on a rollercoaster with Ash Tyler in Season 2, giving her a settled relationship worked very well. It was a shame Discovery went down this road in the first place, but all the pieces seem to be in place for a satisfactory conclusion.
Theory #4:
Oros is alive – and we’ll see him soon!
The revelation that Tarka’s plan will actually end up killing everyone is a bit of a damp squib; an unnecessary twist that took the character from complex and understandable to out-and-out villain. However, because of the nuanced and interesting characterisation over the preceding few episodes, part of me is still rooting for some kind of reunion between Tarka and the long-lost Oros.
Perhaps Discovery will surprise us by showing Tarka’s plan succeed – he could activate his interdimensional transporter and disappear, leaving Captain Burnham to pick up the pieces. Or maybe a series that has talked big on middle grounds, compromises, and diplomacy will see Captain Burnham or President Rillak reach out to Tarka, offering him a different pathway to success.
Discovery teased us unnecessarily by keeping Oros’ identity a secret before showing us the character in quite a bit of depth. It would be a shame if Oros only exists in flashbacks; less a character than a narrative device to give Tarka’s quest a motivating factor.
Theory #5:
The interdimensional transporter works!
Connected to the theory above, if Tarka is to succeed in his goal of reaching Kayalise then his interdimensional transporter needs to work! He’s convinced that it does, and that the one Oros built at the prison camp also worked. If the two are to have any hope of reuniting, this crucial (and power-hungry) piece of technology is essential.
In narrative terms, the interdimensional transporter is a macguffin right now. But it has huge potential – perhaps opening up future Discovery or 32nd Century stories involving visits to parallel universes. This could even be the way that the outlying story of Calypso is brought into the fold. In short, there are many good reasons to demonstrate its success!
Theory #6:
The Guardian of Forever will make an appearance.
Earlier in the season I’d been speculating that Captain Burnham could turn to the Guardian of Forever for help with the DMA. That didn’t happen (she seems to have entirely forgotten about the Guardian’s existence) but there is still a way to bring the Guardian back into the story in a way that makes sense.
In short, Season 3 saw the Guardian send Georgiou to an alternate reality, so it stands to reason it could do the same for Tarka. The Guardian of Forever is one of the few ways that could allow everyone to get what they want: the DMA could be moved away from Earth and inhabited worlds, Unknown Species 10-C could continue to mine boronite, and Tarka could use the Guardian to travel to Kayalise. There’s also a remote possibility that the Guardian could be used to send the USS Discovery back in time as part of a tie-in with Calypso, but at this late stage in the season I don’t think we’ll get that.
Theory #7:
A major character will be killed off.
This would’ve made more sense earlier in the season, with the death of a major character potentially setting up the danger of the DMA and Unknown Species 10-C, but even at this late stage it could still be impactful. Right now, Tarka has to be top of the list for not surviving the finale. Somehow, Captain Burnham will have to stop him, and one reliable way to do that would be for him to be killed! This happened in Season 1 with Lorca, in Season 2 with Control, and in Season 3 with Osyraa, so Discovery has precedent for killing its villains.
However, there are other possibilities. Lieutenant Commander Bryce is very high on the list following his emotional goodbye with Saru a couple of episodes ago, and had warranted his own entry on the theory list for the past couple of weeks! Then we have Book and Reno, who are trapped with Tarka aboard Book’s ship. One or both of them could be killed, either accidentally or intentionally, during Tarka’s quest to reach Kayalise.
The departures of Gray and Tilly have the potential to shake up the cast as Discovery prepares for its fifth season, but both characters have just left the ship to do other things; they could return at any time and their friends know that they’re safe. A character death – if well-timed and pulled off with the right weight and emotion – can be incredibly impactful, not only to the characters they leave behind, but to us as the audience as well.
At points this season, I’ve felt that Discovery has given even its minor characters some pretty heavy plot armour. And if the aim was to communicate the stakes involved with the DMA and Unknown Species 10-C, a character death this late in the game would miss the mark. But there’s still time for a dramatic twist of this kind!
In ranked order of how likely I think they are to die in the season finale, we have the following characters: Tarka, Bryce, Reno, Tilly, and Booker.
So those theories saw movement this week.
We still have a number of theories left in play, with quite a few seeming increasingly unlikely to be included this season. However, it’s possible for the season to end with a cliffhanger, or for the final act of the season finale to set up something big for Season 5 that could include any of these story elements. I’ll recap the remaining theories here.
Theory #8:
We’ll learn more about who Dr Kovich is and what position he has within the Federation.
I have four theories about Dr Kovich that came to the fore in The Galactic Barrier. In that episode, Dr Kovich claimed to have “more important things” to do than accompany the USS Discovery to Unknown Species 10-C’s hyperfield. This prompted a lot of speculation – but with the last two episodes having ignored him altogether, this could be one of those Discovery lines that sounds exciting and interesting… but ultimately has no payoff of any kind.
Regardless, here are my Kovich theories summarised:
Theory #8-A:
Dr Kovich works for Section 31.
Section 31 is the off-the-books, black ops division of Starfleet Intelligence. They run morally questionable operations and even attempted to commit genocide against the Founders of the Dominion in Deep Space Nine. I originally pegged Dr Kovich as a Section 31 leader back in Season 3 for his treatment of Georgiou. He also seems to have a very wide range of skills and a lot of power: appointing Starfleet Academy instructors, having access to classified intelligence, and acting as a therapist or psychiatrist are all things we’ve seen him do.
Theory #8-B:
Dr Kovich is Vice President of the Federation.
We got confirmation a couple of episodes ago that President Rillak has an unnamed Vice President. This character was only mentioned briefly and their name wasn’t revealed, so it’s possible they’ll never be shown on screen and won’t matter to the story. However, it seems at least plausible that Dr Kovich is the Vice President; it could account for his powerful role within the Federation hierarchy and give him a reason to remain behind.
Theory #8-C:
Dr Kovich is a Q (or similar alien).
This would be a complete twist, but I wonder if the reason for Dr Kovich’s enigmatic nature is that he’s a member of the Q Continuum. It could be revealed that Dr Kovich is from an alien race and has been observing the Federation while trying to offer limited help and guidance – not dissimilar to how Q operated. This could explain why he seems to offer fairly limited help, at times, or sets up other characters to make breakthroughs with a little prompting.
Theory #8-D:
Dr Kovich is preparing a weapon of last resort to strike Unknown Species 10-C.
One reason why Dr Kovich may have remained at Federation HQ (regardless of what his job title is) could be to prepare a backup plan in case the USS Discovery’s mission fails. This could take the form of some kind of “weapon of last resort” which could be far more powerful than Tarka’s isolytic weapon. It could also make use of time travel, or even be a weaponised form of the Burn.
Theory #9:
Admiral Vance’s holo-message about Earth and Ni’Var was fake or has been tampered with.
As I said in my review, this is the one part of The Galactic Barrier that I wasn’t wild about. Earth being in trouble is a cliché, and one which really makes the ending of the season feel like an inevitability – with Earth, Titan, Ni’Var, and the rest of the Sol and Vulcan systems in danger, it’s unfathomable that the DMA won’t be stopped in time. But I digress!
If there are other plans afoot at Federation HQ then it’s plausible to think that someone either faked or tampered with Admiral Vance’s holo-message, meaning that the information Captain Burnham and the crew received wasn’t correct. It could lead to an attempt at a dramatic finale, with Captain Burnham thinking she’s too late to have saved Earth… only to discover that Earth is fine because it was never in danger to begin with!
Theory #10:
The ban on time travel will be explained in more detail.
As mentioned above, there may be plans afoot within the Federation and Starfleet to strike Unknown Species 10-C, and a weaponised form of time travel could be a last-resort weapon that the Federation – and other galactic races – might consider using. If so, perhaps the ban on time travel that was introduced in Season 3 will be explained in more detail or expanded upon.
The ban made storytelling sense; it was a way to avoid questions about how the 32nd Century was so different to the far future glimpsed in past iterations of Star Trek, it prevented an easy fix to Georgiou’s health condition, and it prevented any of the main cast returning to the 23rd Century. But it also raised some issues for nitpicking Trekkies like us! The biggest one was how something like this could possibly be enforced; it isn’t possible to un-invent a powerful, weaponisable technology, and even if every single race in the galaxy agreed to the ban in theory, it seems like it would need an incredible level of oversight to enforce it. Finding out more about how the ban works is as much a hope as a theory in some respects, but I think it’s something Discovery should at least attempt to do!
Theory #11:
The Federation has flouted the ban on time travel (or is about to).
As above, it may be possible that the Federation is about to make a move using time travel to attack Unknown Species 10-C. If so, we may be about to learn that it isn’t the first time that they have failed to abide by the rules set out in the ban on time travel.
It doesn’t seem likely that the DMA is directly related to time travel, as I had previously suggested. But if time travel is about to come into play, we could learn more about the ban and the Federation’s relationship to it.
Theory #12:
Unknown Species 10-C built the Galactic Barrier.
Given their technological capabilities, it doesn’t seem impossible that Unknown Species 10-C constructed the Galactic Barrier – perhaps as a way to shield themselves from the races of the Milky Way, or perhaps to keep anyone from exploring too far and discovering their location. There are many reasons why a technologically advanced race might want to build something on this scale – and we could even learn that the harvested boronite is being used to fuel the Galactic Barrier itself.
One possible explanation for why Unknown Species 10-C might want to build something like the Galactic Barrier is to keep the Milky Way’s inhabitants in… but it could also be a shield designed to keep someone else out. That raises a very frightening question: what could be so powerful that a barrier is needed around the entire galaxy? And what could be so dangerous that being locked inside a galaxy with the Borg would be preferable?
With Unknown Species 10-C seemingly being very secretive, I think the idea of them building it to shield themselves is more likely… but there are definitely a lot of ways this theory could go!
Theory #13:
Someone else built the Galactic Barrier to keep Unknown Species 10-C out.
If the Galactic Barrier is an artificial construct, perhaps it was created by another race or faction as a shield against Unknown Species 10-C. It could be the case that Unknown Species 10-C has used DMA technology against the Milky Way in the distant past, and some other race or faction constructed the Galactic Barrier to keep them out. If Unknown Species 10-C are belligerent and interested in conquest, it might take something on a galactic scale to keep the Milky Way safe. A race like the Q could be responsible if that’s the case.
Obviously this theory and the one above can’t both be right! And it’s a distinct possibility that the Galactic Barrier element of the story was just a convenient macguffin to blind Starfleet to Unknown Species 10-C and prevent easy travel to their region of space, dragging out the story and prolonging attempts at communication so other narrative threads could play out.
If that’s the case, we may learn nothing about the Galactic Barrier in the season finale! However, I still think it’s interesting to consider the possibilities, and it could be fun to finally get some more detail on this lesser-known but significant aspect of the Star Trek galaxy.
Theory #14:
There will be a character crossover from a past iteration of Star Trek.
There are many ways to bring back a character from a past iteration of the franchise and incorporate them into the story of Season 4 – and there would be many potential benefits to doing so! I had initially proposed a version of this theory in the run-up to Season 3 that centred on the Doctor from Voyager – but with some creative technobabble, practically anyone could be included, despite the leap forward in time.
Choose To Live showed us the Abronians in cryo-sleep, and Stormy Weather saw the crew of Discovery use the transporter buffer to survive – just like Scotty had done in The Next Generation Season 6 episode Relics. Could these be hints at something to come?
It would also be possible for Captain Burnham to discover the logs or a holographic recording of a long-dead character – and while this would be less of a “crossover,” it could still be a ton of fun and great fan-service!
Theory #15:
Book will find Kyheem and Leto inside the hyperfield.
In Star Trek: Generations, Captain Picard encountered Captain Kirk inside the Nexus – despite Kirk being declared “dead” after the Enterprise-B encountered the energy ribbon almost eighty years earlier. Now that we know a little more about how the DMA operates, it seems at least faintly possible that, just like Captain Kirk, the inhabitants of Kwejian may not be as dead as they first appear.
This theory is, I freely admit, a bit of a long-shot. But the wormhole technology that we know the DMA uses seems to be capable of sending some of what it harvests or mines back to Unknown Species 10-C’s base of operations. Maybe that means that some of the people from Kwejian were transported there instead of being killed. Now that Book is inside the hyperfield, could a reunion of some kind be possible?
Theory #16:
Michael Burnham won’t remain captain of the USS Discovery.
It’s possible that Captain Burnham will have to go to extreme lengths to stop the DMA and/or Tarka, and while I doubt very much that she’ll be killed off, something major could happen in the season finale that sets the stage for her departure from the series.
The developing situation between Captain Burnham and Book could end up with her choosing to resign her commission or taking a new job within Starfleet. Her role as captain of Discovery forced her to choose her responsibility to the Federation over her relationship, and after she was almost forced to kill Book, it would be understandable if Captain Burnham never wanted to be put in that position ever again!
It wouldn’t be the first time Captain Burnham has been unsure of her place in Starfleet and what role she wants to have. We saw this in Season 3 as part of the background that set up her eventual ascent to the captaincy, and while it seems unlikely that it will come back into play in a big way, the situation with Book could be a catalyst for Captain Burnham wanting to have a simpler life either outside of Starfleet or, at the very least, out of the captain’s chair.
This would also continue a trend that Discovery has had across all four seasons thus far: the rotating captaincy of the ship. Each season has seen a new captain in command, and with Season 5 in the offing, it’s got to be at least possible that this trend will continue. I’m not really in favour of this, but it’s certainly interesting to consider. Because Captain Burnham has been the show’s protagonist since Season 1, it seems unlikely, and the overall arc of Discovery between Season 1 and Season 3 can be read as her redemption and ascent to the captaincy. But the show’s revolving door of captains may continue, and her conflict with Book and the difficult emotional situation it put her in could be the trigger to make this happen.
Theory #17:
Saru will be given the captaincy of the USS Voyager-J.
Saru’s future was briefly discussed before he offered to serve as Captain Burnham’s first officer in the episode Anomaly. He has already been offered a command of his own, so Starfleet clearly values his command abilities and experience. President Rillak was seen to be assessing Captain Burnham’s suitability for the captaincy of the USS Voyager-J in Kobayashi Maru… and she mentioned having a shortlist of candidates. Could Saru be on her list?
Several of the qualities that President Rillak said she was looking for in a potential captain seem to apply to Saru. He’s more level-headed, less likely to put himself in a dangerous situation, and more inclined to think of the big picture. He has a weakness when it comes to Kaminar, as we saw toward the end of Season 3, but generally speaking he isn’t someone who lets his emotions get the better of him. His wisdom and calm demeanour could be valuable in the captain’s chair of the Federation flagship. This could also set the stage for his departure from the show, or possibly even for a new show following his adventures aboard his new ship.
Theory #18:
Season 4 will connect with the Short Treks episode Calypso.
Zora’s status as a member of the crew was confirmed in But To Connect, and this followed her developing emotions and sentience earlier in the season. Zora is now much closer to her presentation in Calypso, potentially bringing the story of the Short Treks episode one step closer.
With just one episode remaining and a lot of other storylines to get through, this one feels less and less likely – but it could be an interesting cliffhanger ending if the ship had to be sent back in time!
Theory #19:
Some areas of the galaxy – such as the Delta Quadrant – avoided the worst effects of the Burn.
In But To Connect, President Rillak told us that the diplomatic summit she convened would bring together races from “all four” quadrants. Assuming she was referring to the familiar Alpha, Beta, Gamma, and Delta Quadrants that make up the Milky Way galaxy, this would count as our first mention of the Delta Quadrant in the 32nd Century. I didn’t spot any familiar Delta Quadrant races (or their emblems) amongst the assembled delegates, however!
I had previously speculated that the Burn may not have affected the entire galaxy equally, and that regions farthest away from the Verubin Nebula may have survived without much damage. I still think that this is a possibility – though whether Discovery will revisit the Burn in any depth, or visit the Delta Quadrant at all, remains unclear.
To see a full write-up of this theory, click or tap here.
Theory #20:
The crew will have to defend the Verubin Nebula.
This one is definitely hanging by a thread right now, at least in terms of Season 4! The story continues to unfold in a very different direction, largely ignoring the main story beats from Season 3. But the dilithium shortage has been mentioned more than once, and as things stand right now, the Federation is in control of the galaxy’s only significant dilithium supply. The Verubin Nebula is almost certainly going to be a target for somebody – even if Unknown Species 10-C don’t care about it.
It begins to stretch credulity to think that all of the belligerent factions and races present in the galaxy would become aware of the Federation controlling this impossibly valuable resource and wouldn’t want to take it for themselves. And while it may not happen now until after the DMA storyline has run its course, I think sooner or later someone is going to want to steal the Verubin Nebula and its dilithium. Maybe it will be at the end of Season 4, maybe it will be in Season 5… who knows?
Theory #21:
Tarka will create his own DMA.
In The Examples, we saw Tarka – aided by Stamets – building a scale model of the DMA. Now that his plan to destroy it and seize its controller has failed, perhaps he’ll attempt to recreate the device using the knowledge he acquired. If so, he could inadvertently create a new DMA. Or, through time travel shenanigans, Tarka could turn out to be the creator of the original DMA!
If Tarka isn’t able to find a power source for his interdimensional transporter on the far side of the Galactic Barrier, he may feel he has no choice but to try and recreate the DMA’s original power source.
Theory #22:
We haven’t seen the last of the Abronians.
I currently have four ideas for different ways that the Abronians – the non-humanoid race that Captain Burnham, Tilly, and the Qowat Milat helped save from cryo-sleep in the episode Choose To Live – could play a further role in Season 4. Time is ticking away… but it’s still possible!
Theory #22-A:
The Abronians’ homeworld was destroyed by the DMA.
After arriving at the Abronians’ cryo-ship, Captain Burnham found a stone carving that seemed to depict the destruction of the Abronians’ homeworld. This carving was only shown on screen briefly, but it seemed to show the planet being damaged or destroyed in a large explosion. Burnham credited the planet’s destruction to a “supernova,” and the story then raced ahead.
We’re running out of time with this one – and it could be that Captain Burnham’s initial observation was correct. But this would be one way to connect this side-story to the season’s main narrative arc.
Theory #22-B:
The Abronians’ homeworld was on the other side of the DMA.
One thing struck me as odd about the Abronians: the Federation was entirely unaware of them, despite the Abronian cryo-ship being relatively close to Federation space – such that Captain Burnham could reach it using Book’s ship in a short span of time. It’s possible that the Abronians had been asleep for millennia, unnoticed by the Federation and the wider galaxy for all that time. But it’s also at least possible that their cryo-ship is a newcomer to the area.
Having seen the destruction present on Unknown Species 10-C’s ex-homeworld, maybe the Abronians fell victim to the same devastating event if their original planet was in the same region of extragalactic space.
Theory #22-C:
The Abronians will return to help the Federation.
One of the themes of Discovery since Season 3 has been connection, including building connections between the Federation and other races and organisations. The Abronians were awoken from cryo-sleep thanks to the interventions of Captain Burnham and Tilly – at least in part – and they may seek to repay the Federation, or Captain Burnham personally, for that help.
We saw this play out last season with Ni’Var; in the season finale Ni’Var ships raced to the Federation’s aid as the Emerald Chain attacked. Perhaps the Abronians will likewise step up to help when the Federation needs allies.
Theory #22-D:
The Abronians’ moon-ship may be useful in a later story.
The cryo-ship used by the Abronians was huge, and appeared to have the mass of a planetoid or small moon. With Earth and Ni’Var now under threat and an evacuation necessary, perhaps the Federation will ask the Abronians to borrow their moon-ship. This could even be what Dr Kovich was planning to do and why he couldn’t join Discovery on the mission through the Galactic Barrier.
The moon-ship was fully operational thanks to the new dilithium that J’Vini “procured,” so it could be commandeered by Starfleet for the purposes of an evacuation. That would be one way to pay off what is, at the moment, a side-story.
Theory #23:
Kayalise is the Kelvin universe.
Oros didn’t make clear, in the flashback sequences we saw, exactly what Kayalise would be like. He only believed that it would be better than the prime universe, and talked about it in mythological, almost religious terms. That could mean something significant, or it could simply be Oros being poetic!
Tarka had previously suggested that the universe he hopes to escape to is one where the Burn didn’t happen and the Emerald Chain never rose to power. Because of the unique circumstances of the Burn, it seems at least possible that it didn’t occur in the Kelvin timeline – the one established by 2009’s Star Trek. We’ve already had at least one Kelvin reference in Discovery’s 32nd Century, confirming that the universe was known to exist and was reachable. With a fourth Kelvin film in early production, it’s possible that Kayalise is actually the Kelvin universe!
So that’s the main theory list!
We now have three production-side theories in play, so we’ll look at those too before we wrap things up.
Production-side theory #1:
There will be some kind of crossover with Star Trek: Picard Season 2.
This theory has arisen in large part because of the very odd scheduling of Picard Season 2 and Discovery Season 4, which will run alongside each other for three episodes. I wonder if that’s because some kind of crossover is on the agenda. With time travel playing a significant role in the story of Picard Season 2, it seems at least plausible to think that some kind of connection is possible!
This could be a complete over-reach, and the ultimate “explanation” for the weird scheduling may turn out to be nothing more than the random illogical spasms of the ineptly-managed Paramount+ and parent company Paramount Global. That would not surprise me in the slightest! But I really do find the scheduling odd.
The shorter seasons of today’s Star Trek shows means that there really isn’t any need for such a pile-up this spring. Discovery has thirteen episodes, Picard and Strange New Worlds have ten apiece – and even with Lower Decks and Prodigy still to come, there are more than enough weeks in 2022 for the entire Star Trek franchise to be evenly spread out. Why have four out of ten weeks with two episodes from two different shows, then a gap of several weeks later in the year where no new Star Trek is broadcast? It makes no sense – especially not on a streaming platform.
Finally, with the constipated international rollout of Paramount+ showing no signs of speeding up, it’s looking increasingly likely that Strange New Worlds will be broadcast in the United States weeks or months ahead of its international premiere. If both Picard Season 2 and Strange New Worlds were delayed by as little as 5 or 6 weeks, this might be able to be avoided – assuming the rollout of Paramount+ “by the end of Q2” happens as planned.
In short, it’s all very strange – but one possible explanation for the weird scheduling could be that there’s a crossover event planned sometime in the next three weeks!
Production-side theory #2:
Tilly’s departure will be permanent.
Mary Wiseman confirmed in an interview with Wil Wheaton on The Ready Room (Discovery’s social media aftershow) that Tilly will be seen again before the end of Season 4, and we glimpsed her in the trailer for the second half of the season as well. But that doesn’t mean she will return as a main character on the show going forward, and her departure in All Is Possible felt permanent. Despite that, I’ve seen quite a lot of folks online who don’t believe that Tilly is actually leaving the series – so I wanted to put it out there officially and say that, in my opinion anyway, she is.
Maybe those people know something that I don’t! As I always say, I don’t have any “insider information;” all of this is just speculation on my part. However, I feel that the manner of Tilly’s departure, the fact that she got that emotional sequence with Captain Burnham, a montage showing her leaving the ship, Adira seeming to take over several of her roles, and her departure feeling like the culmination of her arc going back to the latter part of Season 3 all come together to strongly indicate that she won’t be back as a major character. She may yet have a significant role to play in a future Season 4 episode, as has been suggested, but unless Discovery’s writers are really playing with our emotions I believe we’ve seen Tilly’s end as a main character on the show. She may come back in a future Starfleet Academy series, though… so watch this space!
Production-side theory #3:
Season 4 will end on a cliffhanger!
Star Trek has a long, well-established tradition of season-ending cliffhangers! There have been some truly shocking ones in the past, including The Best of Both Worlds in The Next Generation, Deep Space Nine’s Call To Arms, Equinox in Voyager… and many more! With the story of Unknown Species 10-C and the DMA slowly being unpicked, it could be the case that we’ll get a clean resolution – like we did at the end of Season 3. But it’s also possible, in my opinion, that Season 4 will end in similar fashion to Season 2 – on a major cliffhanger!
That could be because the Unknown Species 10-C story didn’t conclude, or a war with the mysterious faction is about to break out. But the Season 4 finale could also set up the beginnings of Season 5’s story, just like how the final moments of Season 1 saw Captain Pike’s Enterprise link up with the USS Discovery.
So that’s it!
We still have a long list of theories as we head into the season finale. Obviously most of them won’t pan out – there isn’t time in a single episode to pay off even half of those still on the list! But they all seem possible or plausible to me, and with a fifth season of Discovery having been confirmed, maybe we’ll see some of them return in 2023 when I start putting together my Season 5 theories!
I always like to end these theory lists by saying that I do this just for fun. I enjoy writing, I enjoy Star Trek, and spending more time in this world is an escape and an enjoyable distraction. But for some folks, fan theories can be frustrating or unenjoyable, especially if they get very attached to a plausible-sounding theory that ultimately doesn’t pan out. I have no “insider information” and I’m not trying to claim that anything suggested above can, will, or must be part of Discovery Season 4. I fully expect many of these theories to be debunked and for the season to go in wildly unpredictable directions!
