Star Trek: Discovery Season 4 – a wishlist

Spoiler Warning: There are spoilers ahead for Star Trek: Discovery Seasons 1-3 and the trailers and teasers for Season 4. Spoilers are also present for the following Star Trek productions: The Voyage Home, The Final Frontier, The Undiscovered Country, The Next Generation, First Contact, Voyager, Enterprise, and Picard.

Discovery’s fourth season is now less than a month away, so it’s time to look ahead. This time, though, I’m not going to be indulging in theory-crafting or even speculation… what we’re going to go through today are some of my wishes for the season. I did something similar last year in the run-up to Season 3, and if you want to see how my wishlist turned out you can find a follow-up piece I wrote after the season had aired by clicking or tapping here.

Season 3 did a reasonably good job at establishing the USS Discovery’s place in the 32nd Century, and though I have criticisms of several aspects of the Burn storyline, it was brought to a fairly conclusive end by the season finale. That should mean that the stage is set for a new story this time around, and on this occasion I’d like to lay out some of my personal preferences for Season 4 and how I’d like to see things unfold.

The obvious caveat applies: I have no “insider information” and I’m not trying to claim that anything on the list below will be included in Season 4. This is merely a wishlist from a fan of Star Trek… nothing more. Everything I’m about to say is also entirely subjective! If I don’t include a point you want to see, or something I talk about sounds like something you’d hate, that’s okay. The Star Trek fandom is expansive enough for fans with all kinds of different points of view; we don’t need to fight, especially not about hypotheticals!

With all of that out of the way, let’s get into my Discovery Season 4 wishlist.

Number 1: A proper role for ex-Captain Saru that makes sense.

Saru in the Season 4 trailer.

One of the things I didn’t like about the short Season 3 epilogue at the end of That Hope Is You, Part 2 was that Saru was unceremoniously shuffled off Discovery. In order to make way for Burnham’s ascent to the captain’s chair, Captain Saru had to leave his position on the ship, and a way was found to make this plausible by giving him a deeply emotional connection to Su’Kal.

As a story point, I actually don’t fault any of that. Saru had been feeling alone and isolated with no other Kelpiens around in the 32nd Century, and his desire to help Su’Kal led to them forming a close bond. I can quite believe that he’d want to take a leave of absence to visit Kaminar and to spend more time with Su’Kal, helping him integrate into society as best he can after so long on his own.

Su’Kal and Saru in Season 3.

But unfortunately the rushed epilogue didn’t do justice to this story point, and quite frankly treated Saru with disrespect. Not since Dr Pulaski was dropped at the beginning of Season 3 of The Next Generation has a main character been handled so poorly, and I would have wanted – and expected – to see much more of a send-off for Saru. Not only had he been Discovery’s captain for all of Season 3, but he was a character we’d spent a lot of time with across Seasons 1 and 2 as well.

Season 4 will bring back Saru; he isn’t leaving the series as some folks had predicted, and I’m glad for that! But his role in Season 4 is unclear at best, and the biggest question I have is this: why does the USS Discovery need two captains on board?

Captain Saru was in command of the ship for a time.

In The Final Frontier and The Undiscovered Country, Kirk and Spock would serve on the same ship despite both holding the rank of captain, so it isn’t entirely without precedent in Starfleet for this situation to arise. In that case, though, Kirk had been demoted from the rank of Admiral, and in The Undiscovered Country in particular both officers held different positions: Kirk was in command of the Enterprise, Spock was in command of the overall mission to negotiate with the Klingons.

In short, I think the premiere of Season 4 (or whichever episode brings Saru back to the ship) needs to at least pay lip service to this point. Perhaps Saru could be given a title like “captain of the science department” in the same way as Scotty was “captain of engineering.” I wouldn’t want to see him demoted to the rank of commander – like poor Decker was in The Motion Picture! Presumably Captain Burnham has some degree of leeway when it comes to building her crew, so perhaps she’ll ask Saru to serve in a temporary role. Regardless, I hope Discovery doesn’t just ignore this point.

Number 2: Go into more detail about the ban on time travel.

The Enterprise-E approaching a temporal vortex.

The ban on time travel that was introduced in Season 3 was evidently intended to be a way for Discovery to avoid questions about how the Burn was able to happen, why Georgiou couldn’t simply return to her own time, and why the time-traveling Federation of the 29th and 30th Centuries that we’ve glimpsed in past Star Trek productions had ceased to exist. But the ban has created some storytelling issues in and of itself, and I would like Season 4 to at least try to address some of these.

Firstly, who enforces the ban? Admiral Vance seemed to imply that everyone in the galaxy – from the Emerald Chain to the Federation – simply goes along with it, but that doesn’t hold up to scrutiny. Yes, the Temporal War was certainly a bad thing. But as the war and its effects fade into memory, are we seriously supposed to believe that someone like Osyraa wouldn’t jump at the chance to use time travel to give herself and her faction an advantage? That’s to say nothing of factions like the Borg – are they signed up to the ban on time travel too?

Osyraa, head of the Emerald Chain in Season 3. She seems like someone who would use any weapon or technology at her disposal – regardless of any ban!

Even if the answer is “all pieces of time travel technology were destroyed,” that doesn’t really hold water either. It’s impossible to un-invent a powerful, weaponisable technology – as I said on several occasions during Season 3’s run! Even if everything were destroyed – something which seems like it would be impossible for every faction to prove – what’s to stop someone recreating it? The Emerald Chain had scientists like Aurellio at their disposal, and once the basic principles were understood it seems like rebuilding the technology would be a task within reach of anyone with the means and inclination.

Time travel was considered something so mundane in the 29th and 30th Centuries that its basic principles were taught in school across the Federation. Even if we discount early depictions of time travel (like the slingshot method seen in The Original Series), the fact that time travel is possible has been known to the Federation since the 22nd or 23rd Centuries at least, and even if we’re generous and say that time travel technology wasn’t “officially” invented until much later, the technology still existed for centuries prior to being banned.

The HMS Bounty was easily able to travel back in time by slingshotting around a star.

In today’s world, nuclear weapons are a comparable technology. If there were a worldwide ban on nuclear weapons, would we trust the likes of China or Russia to abide by it? Could we guarantee that every nuclear weapon was destroyed by our own governments, or might some covert hawkish faction seek to keep control of at least some of them as a contingency? In short, a ban on nuclear weapons is a noble ambition – but even in the aftermath of a nuclear war I can’t see it being workable. Even if such a ban were put in place, the weapons programmes of countries like North Korea prove that, with enough determination, anyone can recreate complex technology from scratch.

Perhaps there’s some kind of time travel arbiter that monitors the whole galaxy, and intervenes to prevent time travel from occurring. That would be one explanation. But it’s also possible that whatever this gravitational anomaly is is connected to time travel or the Temporal War – meaning Captain Burnham and the crew could be about to dive headfirst into a time travel story!

Number 3: Standalone episodes and smaller storylines to offset the main season-long arc.

The Season 3 two-parter Terra Firma was largely a standalone story.

Discovery used this formula to great effect in Season 3, which came after Seasons 1 and 2 had both leaned very heavily into serialised storytelling. I very much hope that Season 4 will continue in the same vein, because having smaller stories, character arcs, and fully standalone episodes added so much depth to the series.

We already know of one potential side-story: Adira and Gray, and in particular Gray’s quest to become corporeal again. That story has a lot of potential, and it’s actually one of the things I’m most looking forward to about Season 4. Hopefully there can be more side-stories like this, looking at other characters and taking some of our heroes to different and unexpected places.

Gray and Adira in Season 3.

Strange New Worlds has promised a return to a more episodic style of storytelling. I don’t expect that Discovery will go all-in on episodic television in the same way, not least because we already know that they have the mystery of the gravitational anomaly to solve. But I hope that, along the way, we get some detours and unconnected stories that take Captain Burnham and the ship to different places – literally and thematically.

This would be a great way for the series to show off characters who didn’t get as much to do last season, or who we haven’t spent much time with at all. Season 3 brought us an interesting story involving helm officer Keyla Detmer, and while that story wasn’t perfect it was great to spend time with a secondary character in far more detail than Discovery had ever done before. Which brings us to my next point…

Number 4: Make use of the show’s full cast – including secondary and recurring characters.

Some of the bridge crew at the end of Season 3.

As mentioned, Season 3 began this process. We got to spend more time away from Michael Burnham than Discovery had dared do in Seasons 1 or 2, and some of the episodes which placed Saru, Booker, and even Georgiou at their centre worked exceptionally well. I’d love Discovery to continue down this road, perhaps spending time with characters like Stamets – he didn’t get as much to do in Season 3 as some of the others.

With Georgiou departing for an unknown destination last year, there’s potentially space for another main cast member. We could see someone like Bryce, Rhys, or Nilsson promoted – or a character like Willa, Admiral Vance’s aide-de-camp from Season 3, join the crew. In some ways I’d like to see a new character, perhaps a 32nd Century Starfleet officer. Booker provides the crew with the viewpoint of a 32nd Century native, but he also has a different role as an outsider who isn’t a member of Starfleet. Bringing a new officer who’s native to this era aboard the ship could be an excellent move, one which could provide a lot of storytelling potential.

Detmer got her own storyline last season.

At the same time, giving more characters moments in the spotlight and their own arcs is something worth doing. We learned more about people like Owosekun, Detmer, and even Tilly in Season 3 than we ever had before, and continuing this trend by ensuring more characters get some degree of exploration is absolutely something I’d want to see.

In a season that will run for 13 episodes there’s obviously a limit; a ceiling on the number of characters and storylines that the series can fit. With that understood it obviously won’t be possible for everyone to get a fully-rounded character arc, their own storyline, and a spotlight episode putting them front-and-centre! But choosing some characters to give that amount of attention to is still important, and even those characters who don’t get a full story or their own episode this time can still have more to do than sit at their station and say “yes ma’am!”

Number 5: Bring back Nhan!

Could Nhan make a comeback?

Saru wasn’t the only character who left the USS Discovery and whose story feels incomplete. Nhan actress Rachael Ancheril was promoted to Discovery’s main cast at the beginning of Season 3 only to be shuffled off the show after only a few episodes. Nhan – the first Barzan main character in Star Trek’s history – was left behind to be the guardian of the USS Tikhov following a disaster that claimed the lives of the ship’s crew.

The Tikhov’s mission was an interesting one – it serves as a seed vault for the Federation, storing samples of plants from across the Federation and beyond. From the point of view of Nhan potentially reuniting with Burnham and the crew, though, the Tikhov was rotated between Federation member worlds, with representatives from each taking responsibility for the ship for a set period of time. Nhan seemed to suggest that she saw her mission as keeping the ship safe until the end of the Barzans’ tenure, after which it’s safe to assume the ship would be delivered to a new commander.

Nham hugs Burnham immediately before remaining behind on the USS Tikhov.

It wasn’t stated on screen how long each planet’s turn to look after the ship lasts, but that’s actually a good thing! It could be that each member world has to care for the ship for a year or two, or that it was almost the end of Barzan II’s tenure as guardians of the Tikhov – either of which could mean Nhan is almost done and could return to duty.

It was a shame that Nhan was dropped, and I don’t know if there were production-side reasons for the decision. It feels rather arbitrary, and while Nhan wouldn’t necessarily have had a huge role to play in the latter part of Season 3 she was a fun character and someone the show could and should bring back. The USS Discovery doesn’t have a permanent security or tactical officer – at least not among the main characters. Nhan could fill that role going forward, and it seems as if the ship could use a dedicated security officer based on all the scrapes that they get into!

Nhan watches the USS Discovery depart.

Nhan was also a character who provided a contrast to Michael Burnham. Where Burnham could go on emotional rollercoaster rides, Nhan was mostly stoic. And where Burnham had a loose interpretation of the rules and regulations, Nhan appeared steadfast in her dedication to Starfleet’s way of doing things.

As a character from an under-explored race, Nhan could do for the Barzans what Saru has done for the Kelpiens – showing us their history and culture in more detail. The Barzans only appeared a couple of times in Star Trek prior to Discovery, but there’s a chance for a connection with The Next Generation or to explain how they came to join the Federation – and perhaps why they chose to remain a Federation member even after the withdrawal of Earth and Ni’Var. Which brings us to the next point…

Number 6: Give us a broader look at the state of the galaxy in the 32nd Century.

Season 3 focused primarily on two factions: the rump Federation and the Emerald Chain. Earth, Ni’Var, and Kwejian also appeared, though the first two are ex-Federation members. We know that the Burn decimated “the galaxy” and saw many Federation members quit the organisation, but that was 125 years ago – a lot can have happened since.

Though we briefly saw Cardassians, Lurians, and a few other familiar races, we know nothing about many others. What became of the Klingon Empire? The Dominion? The Borg? Was the Burn truly galactic in scope, reaching all four quadrants in equally destructive fashion – or could some parts of the galaxy have escaped some or all of the Burn’s impact?

Are the Borg still around in the 32nd Century?

Admiral Vance told us that 38 member worlds remained in the Federation – with Earth and Ni’Var being two of the most prominent members to leave. But if the Federation had over 350 member worlds at its peak, more than 80% have quit the organisation – or been conquered, destroyed, or had some other fate befall them. Barzan II appears to remain a Federation member, as does Kaminar. It’s possible based on the Season 4 trailer that Ni’Var will rejoin the organisation – but what of the others? Who’s left in the Federation? Who quit? Who joined after the 24th Century that we might recall from past iterations of Star Trek?

Prior to the Burn, did the development of warp or transwarp speeds allow the Federation to travel further and settle other parts of the galaxy, perhaps? Could races like the Ocampa and Talaxians have joined the Federation in the Delta Quadrant, for example?

In short, the 32nd Century is a vast sandbox for the producers and writers to play in! So far we’ve only seen a tiny little corner of that sandbox – so I hope Season 4 can broaden the view and show us a bigger picture of the state of the galaxy and its factions.

Number 7: More Admiral Vance!

Admiral Vance in Season 3.

In Season 3, Admiral Vance embodied the very best of Starfleet’s values. Even though he was dealt a very bad hand in the aftermath of the Burn, he remained loyal not only to the Federation and Starfleet, but to the ideals the organisations have always stood for. Even when negotiating with Osyraa – a powerful adversary – Vance refused to compromise on his convictions.

The arrival of Rillak – a new character who will serve as the Federation’s president – could mean that Admiral Vance is sidelined. If Burnham is reporting directly to the President it seems like she’ll be going over Vance’s head, or at least around him. I guess I’m just concerned that Discovery doesn’t really have space for two “big boss” characters, and that Vance may lose out to Rillak in terms of stories and screen time.

President Rillak could occupy a very similar narrative role to Vance.

It’s possible that Rillak is being set up in a deliberately antagonistic way, and that the decision was taken to keep Vance as a more sympathetic character. I didn’t really like Rillak’s interaction with Captain Burnham in the recent Season 4 trailer, but at the same time what she had to say wasn’t too far removed from what Vance had to say at a couple of points in Season 3. He could take a tougher line with Burnham and Saru when he needed to without coming across as one of Star Trek’s typical “evil admirals!”

Actor Oded Fehr brings Vance to life and gives him a real gravitas, and there’s scope to learn more about who Vance is and what makes him tick. Vance told us he has a wife and child; perhaps we could meet them and see how he is when he’s off-duty in a more casual setting.

When Osyraa and the Emerald Chain were plotting their attack on Federation HQ in Season 3 I was genuinely worried for Admiral Vance! The Emerald Chain attack didn’t kill him off – fortunately – so he lives to fight another day! I know we’ll see him in some capacity in Season 4, but I hope he gets more to do than just chair a few meetings.

Number 8: Kill off a main character.

Who could it be?

Speaking of characters who felt at risk, Season 3 only saw the character of Ryn killed off. Ryn was a fun character for sure, and his death was very sad, but at several key moments where Discovery could have been a little bolder at swinging the proverbial axe, main characters appeared to be safe thanks to their plot armour.

The character I felt most embodied this side of Season 3 was Owosekun. In the season finale it seemed as though she was about to make the ultimate sacrifice – setting off a bomb in a low-oxygen environment – but the Sphere Data-powered DOT robots saved her life at the last minute. There were other characters in that group, including Tilly, Detmer, Bryce, and Rhys, who likewise could’ve been killed off in the season finale.

All of these characters survived last season’s finale.

I’m not arguing for any one specific character to be immediately killed off, and as I like all of the main characters for their own unique reasons any death would be a tragedy! But some stories work better or feel more impactful when the heroes lose a friend, and the Season 3 finale would have undeniably had a lot more emotional weight if someone hadn’t made it to the end.

So Season 4, here’s your challenge: kill off a main character! Let’s not repeat what happened to Nhan and Georgiou, being shuffled off the ship to some other destination. And let’s not set up a story where everyone is in danger only to have them all miraculously saved at the end. Instead let’s actually kill off a major character at the right point in the story. Doing so would raise the stakes dramatically and hammer home that whatever threat Captain Burnham and the crew are facing is genuinely deadly.

Number 9: A character crossover from a past iteration of Star Trek.

The Doctor from Voyager.

This isn’t the first time I’ve suggested this idea! But as Lower Decks has shown on several occasions, bringing back a character from Star Trek’s past can be a lot of fun – and emotional for longstanding Trekkies. Last season I suggested Voyager’s Doctor – or rather, a backup copy of him from the Season 4 episode Living Witness – as a potential character crossover, as the chances of him being alive in the 32nd Century seemed higher than most!

Given Star Trek’s technobabble, however, an excuse could be found to bring back practically anyone. Characters from Enterprise, Deep Space Nine, or even Picard could all appear in some form – through stasis or cryogenic suspension, in synthetic bodies, as holograms, trapped in transporter beams, frozen solid under the surface of an ice planet… and so on! With a little creativity, Discovery Season 4 could find a way to bring back pretty much anybody, and doing so would be absolutely wonderful.

Scotty appeared in Season 6 of The Next Generation thanks to sci-fi magic!

Aside from Voyager’s Doctor, I could suggest Enterprise’s Temporal Agent Daniels, Picard’s Soji or Deep Space Nine’s Dax symbiont as contenders for characters who could potentially have survived to the 32nd Century through “natural” means. Soji, as a character in a series running alongside Discovery, would be a fascinating choice – but at the same time I could understand if the producers don’t want to go down that route for fear of affecting or restricting future Picard stories.

If I were to fantasise I might suggest a character like Riker or Chekov. Even if they were only seen as holograms or in a recorded message I think including a “classic” character like that would mean so much to fans. We saw something comparable to this in Season 3’s Unification III, where a hologram of Spock was briefly shown. But to bring back actors like Jonathan Frakes or Walter Koenig to record even just a short message that Captain Burnham could discover would be amazing.

Number 10: Make some kind of reference to anything from Lower Decks!

Lower Decks Season 2 has just finished its run.

Lower Decks has now got two seasons under its belt, and although there were some teething problems at first caused by the lack of an international broadcast during Season 1, the show has definitely hit its stride. It would be absolutely amazing for Discovery Season 4 to so much as name-drop an event, character, or location from Lower Decks, even if it was just a throwaway line that had no bearing on the plot.

This isn’t just about fan service, either. At present, Star Trek’s shows are all split up, occupying different places and completely different time-frames. There will be a connection between Discovery and Strange New Worlds when the latter premieres next year, but there’s no chance for a significant crossover. Name-drops and references are the next best thing, and a way for the Star Trek franchise to remain connected.

Ensigns Tendi, Rutherford, Mariner, and Boimler.

Having wholly standalone shows doesn’t make a lot of sense to me. It’s certainly true that Lower Decks and Discovery are very different in terms of style, tone, and subject matter – but as two parts of a larger franchise it doesn’t hurt to find ways to connect them. For fans it’s a nice “Easter egg,” but for casual viewers these kinds of connections can be the deciding factor in choosing to check out another show!

As Star Trek fans, we need as many people engaged with as much of Star Trek as possible – it’s the only way the franchise will survive into the future. Having different shows that appeal to different audiences is a great idea in many ways; it casts a broad net and should, in theory, bring in many more viewers and subscribers. But the next step is converting fans of one series to fans of the franchise as a whole – and if there are connections between the shows, even small ones, that’ll encourage at least some viewers to try other Star Trek shows. So if Discovery Season 4 could acknowledge Lower Decks in some way, I think that would be fantastic.

Number 11: Continue the theme of rebuilding – but at a reasonable pace.

Ni’Var seems to have rejoined the Federation.

Season 3 introduced us to the galaxy a century after the Burn. This event devastated the Federation and known space, and clearly saw a major power shift with factions like the Emerald Chain gaining strength. The Burn as a storyline may be resolved, but the galaxy can’t simply be “reset” to how it used to be. An event so devastating will take a long time to recover from. Ni’Var rejoining the Federation is a great first step, but I hope Season 4 doesn’t try to rush these things.

With the gravitational anomaly seeming to be the main focus of Season 4’s story, rebuilding the Federation may take a back seat. However, I’d like to see at least some progress in this area, as it could be one of the major sources of hope and optimism in the story of the post-Burn galaxy. With the dilithium cache from the Verubin Nebula under their control, the Federation is finally in a position to rebuild what has been lost over the past century or more – and from a narrative point of view, bringing wayward planets and races together is a story worth telling.

Independent Earth in Season 3.

At the same time, the story needs to acknowledge the severity of the Burn and strike the right balance when it comes to optimistically putting the pieces back together. Trying to rush this – or worse, trying to pretend that it all happened off-screen – would lead to a truly unsatisfying and unrealistic narrative.

Season 4 can’t simply pretend that the Burn is over and done with and completely move on to new stories. Even though the Burn was clearly intended as the main story of a single season, its massive implications and effects can’t be confined to Season 3 of Discovery. Any other Star Trek stories set in the 32nd Century – and beyond – will need to acknowledge the lingering effects of the Burn, and something as significant as rebuilding the Federation and bringing hope back to worlds that had lost it can’t simply be done off-screen so Captain Burnham and the crew can race away to their next big adventure.

So that’s it. A few of my hopes and wishes for the imminent fourth season of Star Trek: Discovery.

Grudge in the Season 4 trailer!

I don’t think I’d have chosen to go for another “galaxy-ending” apocalyptic threat if I’d been in charge of planning the story of Discovery Season 4. After the Klingon war in Season 1, Control and the Red Angel in Season 2, and the Burn, the collapsed Federation, and the Emerald Chain in Season 3 I would have liked to have seen Captain Burnham and the crew catch a break! Not every season has to be about the imminent destruction of the universe; stories which are smaller in scale can be just as dramatic and just as impactful when done right.

Regardless, this is the direction Discovery seems intent on going, and I’m interested to see what the gravitational anomaly is all about. I’m hopeful that Season 4 can deliver some fun, exciting, dramatic, and interesting Star Trek stories with Captain Burnham in command, and I’m very much looking forward to the new season. Even if none of my wishes are meant to be, Season 4 will undoubtedly still have plenty to offer.

Star Trek: Discovery Season 4 will premiere on Paramount+ in the United States on the 18th of November 2021. An international broadcast will follow on Netflix on the 19th of November 2021.

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 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.

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 – eight “gravitational anomaly” theories

Spoiler Warning: There are spoilers ahead for Star Trek: Discovery Seasons 1-3 and the teaser trailer for Season 4. Further spoilers are present for the following: Star Trek: Picard Season 1, Star Trek: The Next Generation, Star Trek: Generations, Star Trek: Voyager, and Star Trek: Enterprise.

Star Trek’s First Contact Day virtual event has given us an awful lot to digest! We got teasers for Picard Season 2, Lower Decks Season 2, Discovery Season 4, and more details about Prodigy. If you missed the event, I wrote up my impressions of everything we saw, and you can find that article by clicking or tapping here.

This time, I want to look at the teaser for Discovery’s impending fourth season in more depth, and in particular start making some guesses about what may be going on! The teaser was barely ninety seconds long, and with the show at least six months away it may be futile to speculate about pretty much anything! But that hasn’t stopped me in the past, so let’s jump in!

Sonequa Martin-Green plays Captain Michael Burnham in Discovery, and introduced the Season 4 teaser during the First Contact Day event.

My usual disclaimer applies: I don’t have any “insider information.” I’m not offering up these suggestions saying any are unequivocally true. This is nothing more than speculation from a fan – and a chance to spend some more time talking about Star Trek, which I absolutely adore.

In the run-up to Season 3 last year, I spent a lot of time speculating about the event that ultimately turned out to be the Burn. When we first heard its name I put together a list theorising a number of possible connections to past iterations of Star Trek – but as you know by now, none came to pass!

Michael Burnham in Season 3, trying to figure out what caused the Burn.

Discovery has had an on-off relationship with Star Trek’s broader canon. Season 1 sidestepped a lot of things, redesigning the Klingons, visiting the Mirror Universe years before Kirk’s first crossing, and fighting a major war. Season 2 tied itself much closer to canon, bringing in Captain Pike, Spock, and revisiting Talos IV. Season 3 shot forward into the future, and told a story that touched on past iterations of the franchise at points, but had an overall narrative that stood on its own two feet.

In short, trying to guess whether Season 4’s main storyline will be related to something we’ve seen in the past or not is a crapshoot. Maybe it will be, maybe it won’t. Regardless, if it’s going to be something brand-new then naturally the details become impossible to predict! So in this list I’m going to look at eight possibilities from Star Trek’s past that could explain what we saw in the teaser.

A determined-looking (and armoured) Burnham in the Season 4 teaser.

First of all, let’s explain what exactly we saw! Stamets described a “gravitational anomaly” that’s at least five light-years in diameter. This anomaly appears to be incredibly destructive, and if Burnham is correct, it’s appearing and disappearing at random. As a result, it could potentially strike any Federation or non-Federation world or starship without warning.

Assuming that this anomaly is the main problem facing Captain Burnham and her crew in Season 4, I’ve got a few ideas for what it could be, or what it may be related to. I quite like the idea of Discovery sticking with the “natural disaster” concept from Season 3. It worked well last time, and presenting the crew with a puzzle, mystery, or challenge that’s more scientific in nature than military could be wonderful to see. As long as such a storyline manages to avoid feeling either repetitive or anticlimactic, I think it works in principle.

Stamets in the Season 4 teaser. He told us about the “gravitational anomaly.”

One final point of note is that, due to disruption caused by the pandemic, Discovery Season 4 began filming back in November, well before Season 3 had finished airing – and crucially, before the creative team had time to process any feedback they were getting about the season’s themes and storylines. As a result of that, it may be the case that Season 4 doesn’t make as many changes from Season 3 as some fans would have wanted to see. But once again, that’s speculation on my part!

So let’s consider this “gravitational anomaly,” then. What could it be? What have we seen in past iterations of Star Trek that could potentially be involved? Will there be any tie-ins to other ongoing series, such as Picard, or will the show set up something we’ll see return in a future project, such as Strange New Worlds? Let’s jump into the list and see if we can make some reasonable guesses!

Number 1: The Nexus

The Nexus approaching the planet Veridian III.

When I first saw the teaser, my mind immediately went to the Nexus, the energy ribbon seen in Star Trek: Generations. The Nexus was large, more than large enough to engulf an entire planet, and while it may not have been light-years in diameter when we saw it in that film, it’s possible it grew… somehow! The Nexus was incredibly destructive, causing the destruction of two transport ships and seriously damaging the Enterprise-B, not unlike some of the damage suffered by the USS Discovery in the teaser.

There are two crucial points which made me think of the Nexus, though. The first is that the energy ribbon was said to contain a “gravimetric field,” which sounds an awful lot like Stamets’ “gravitational anomaly.” Both seem to be connected to gravity, and as we saw in the teaser, the USS Discovery appears to lose its artificial gravity at one point.

The Enterprise-B trying to manoeuvre inside the Nexus.

The second point I consider key to the Nexus being a possibility is that we already know it’s something that recurs. The Nexus returns to the Milky Way galaxy every 39.1 years (according to Data in Generations) and unless something major happened in the intervening centuries, this force of nature should still be present, periodically crossing through the galaxy.

At a couple of points in the teaser we saw members of Discovery’s crew looking dazed and confused, not unlike how Soran and Guinan appeared after being transported out of the Nexus by the crew of the Enterprise-B. Perhaps we can infer from their demeanours that they’re not quite sure where they are or what just happened – maybe that means they’ve just spent time inside the Nexus’ paradise-like realm.

Though the stated size of the anomaly relative to what we saw in Generations may count against it, I like the idea of revisiting the Nexus. Would Discovery bring aboard a Soran-like villain, someone hell-bent on getting to “paradise?” Maybe!

Number 2: The super-synths from Picard Season 1

The super-synths in Picard Season 1.

It’s absolutely true that I also suggested the super-synths could’ve been the cause of last season’s disaster! But that doesn’t mean I’m done suggesting ways for this unnamed faction to reappear in Star Trek, especially considering that the teaser for Picard Season 2 suggested that series is moving away from them.

At the end of Picard Season 1, we learned that there is a race of super-synths that exist somewhere out in deep space – perhaps many thousands of light-years away from the Milky Way galaxy. They offered to come to the aid of any synths that ask for their help, though whether this offer was genuine or not was not clear – as indeed was very little about the faction!

Jean-Luc Picard managed to prevent the arrival of the super-synths, along with Soji.

Soji and Sutra, two of the synths from Coppelius, attempted to make contact with the super-synths, but despite opening a beacon and a portal to their base, Soji was ultimately convinced to shut it down and cut off her attempt to communicate. We thus learned precious little about who the super-synths are or what their objectives may be. They seemed menacing, and may harbour an anti-organic hatred that could make them diametrically opposed to the Federation.

We know that, in principle, this faction can open portals in space to allow for travel far faster than warp drive. Perhaps getting too close to one of their portals causes the kind of damage seen to the USS Discovery, and their portals may appear to be “gravitational anomalies” when detected on sensors. The super-synths clearly have a powerful understanding of gravity, such that they were literally able to move stars and create a stable eight-star octonary system. It’s thus at least possible that they use gravity or gravitational anomalies as some kind of weapon.

One thing that Picard Season 1 left unresolved was the fate of the super-synths. Having been contacted, were they now aware of the Milky Way and the Federation? Might they be hell-bent on attacking the Federation? If their offer of help wasn’t genuine, might they arrive to attack the synths who live in the Milky Way? There are a lot of unknowns, but it’s at least plausible that they could be involved. As I’ve said numerous times, finding a way for Picard and Discovery to work together, using similar themes, factions, or even characters would be fantastic and something truly worth doing. This may not be the way it happens… but it could be!

Number 3: A graviton ellipse

The USS Voyager once encountered a graviton ellipse.

The Voyager Season 6 episode One Small Step introduced the graviton ellipse, a fast-moving anomaly that can travel through subspace, normal space, and even other dimensions. The ellipse was drawn to electromagnetic energy – such as that emitted by spacecraft! One ellipse appeared in the Sol system in 2032, during an early manned mission to Mars, and “swallowed” the Ares IV ship. It later attempted to do the same to the USS Voyager.

The graviton ellipse was smaller than five light-years across, so again we have to contend with size. But there are points in its favour! Firstly, the ellipse was specifically drawn to spacecraft and other future technology. Though we didn’t see it attempt to “eat” anything on a planet’s surface, it stands to reason that similar technologies used in power generation may emit the same kind of electromagnetic radiation that an ellipse would be drawn to.

The Delta Flyer inside a graviton ellipse.

Secondly, the ellipse moved essentially at random, disappearing into subspace to reappear many thousands of light-years away. One single ellipse was known to have visited both the Alpha and Delta Quadrants. This seems to fit with what we know of Discovery’s “gravitational anomaly” – specifically the part Captain Burnham told us about its random, unpredictable appearances.

Finally, the graviton ellipse was known to cause damage to spacecraft, draining their power, as well as gravity-related disturbances in space. An encounter with an ellipse may not have destroyed Ares IV or the Delta Flyer, but they were known to be very difficult to escape from.

The drawbacks of this option are that graviton ellipses were relatively well-understood as early as the 24th Century, and with Discovery Season 4 set over 800 years later, it stands to reason that the Federation would be well-equipped to at least know what they’re up against if an ellipse seemed to be in the vicinity. Secondly, there was no indication that the ellipse would stay in one area, causing widespread damage in the way Discovery’s fourth season teaser suggested. Despite those negative points, however, I think it’s at least a possibility. Perhaps post-Burn technology has drawn an ellipse to Federation space, or it’s even possible that someone has found a way to weaponise one to attack the Federation.

Number 4: The Sphere-Builders from Enterprise

A Delphic Expanse sphere.

Discovery’s third season had a couple of interesting references to Enterprise, specifically the “Temporal Cold War” arc. One faction involved in the Temporal Cold War were the so-called Sphere-Builders: extradimensional beings who were attempting to convert part of the Milky Way galaxy to match their native realm so they could colonise it.

Though the time-travelling agent Daniels told Captain Archer that the Sphere-Builders were definitively defeated in the 26th Century, Daniels was from a time period before Discovery Season 4 is set, so he may not have been aware of any future involvement they had in galactic affairs!

Captain Archer looks at a projection of spheres in the Delphic Expanse.

The Sphere-Builders, as their name implies, built spheres. These moon-sized objects were spread throughout a region of space known as the Delphic Expanse, and emitted huge amounts of gravimetric energy, causing the entire region to become unstable and peppered with anomalies.

The spheres were also able to cloak, concealing them from 22nd Century human and Vulcan ships. The region of space a single sphere could affect was huge, and in the mid-22nd Century there was a large network of them, perhaps consisting of over 75 individual spheres. A hidden anomaly-generating piece of technology with a connection to the Temporal Wars? That sounds like something that could cause the problems afflicting Captain Burnham’s ship as seen in the teaser!

If a rogue sphere were on the loose, if the Sphere-Builders were returning, or if a single sphere had been left in the Milky Way, forgotten about since the 22nd or 26th Centuries, it stands to reason based on what we know of them that it could be the cause of the “gravitational anomaly.” This concept is potentially interesting; a leftover “doomsday weapon” unattended for centuries could make for a fun story. It would also be great to see a tie-in with Enterprise!

Number 5: Tyken’s Rift

Data explains how a Tyken’s Rift works to the crew of the Enterprise-D.

A Tyken’s Rift was mentioned in the Picard Season 1 episode Nepenthe, but before that one had been seen in more detail in The Next Generation fourth season episode Night Terrors. It was described as a rare spatial anomaly, one capable of encompassing entire star systems.

Unlike some of the other entries on this list, size isn’t a problem for a Tyken’s Rift! If a whole binary star system (i.e. a system with two stars) was able to fit inside, it’s more than possible such an anomaly could be five light-years in diameter!

A Tyken’s Rift was mentioned by Kestra Troi-Riker in Picard Season 1 last year.

The Enterprise-D wasn’t badly damaged by its encounter with the rift, but it was trapped inside and unable to escape. The Tyken’s Rift was also said to drain power, trapping ships inside. Perhaps the damage to the USS Discovery was not caused by the anomaly itself, but by pushing the ship past its limits trying to escape?

The drawback to a Tyken’s Rift being the cause of Discovery’s anomaly is twofold. Firstly, aside from a slow but steady power drain it didn’t seem to be harmful, and we saw nothing in Night Terrors to suggest this anomaly could or would cause catastrophic damage to a ship. And secondly, the Tyken’s Rift that the Enterprise-D encountered appeared to be stationary. It was even included on stellar maps, so it would be easily avoided.

I don’t think either of these points totally rule it out, and as one of the relatively few named anomalies in Star Trek that are massive enough, it seems fair to still include a Tyken’s Rift as a possibility.

Number 6: Species 8472 and Fluidic Space

A member of Species 8472.

One of Voyager’s most interesting adversaries was Species 8472, known only by their Borg designation! This powerful extradimensional faction were able to outwit even the Borg, fighting a very successful war against them for a time.

Species 8472 were native to a realm filled with an organic compound. Voyager’s crew named this region “fluidic space,” and it seemed as though Species 8472 based much of their technology on this organic material, including their spacecraft.

The USS Voyager being pulled toward a fluidic space portal.

The Borg became aware of fluidic space some time in the mid-late 24th Century, and attempted to travel there and assimilate it. But Species 8472 proved resistant to assimilation, and waged a war on the Borg, eventually travelling through to normal space to continue the fight. The intervention of the USS Voyager gave the Borg an advantage, but it seemed shortly thereafter as though the war ground to a stalemate.

Species 8472 made one further incursion, but after an agreement with the USS Voyager, agreed to return to their own dimension, content that the Federation proved no threat. However, that was 800 years ago! A lot can change, and perhaps Species 8472 have decided to make a return.

This would change the “natural disaster” concept, making it perhaps a precursor to invasion. Whether that would be good or not depends on how well it was executed – as well as your personal preferences for storylines! Given what we know of Species 8472 and their technology, I think it’s at least possible they could be the cause. Perhaps Stamets’ anomaly is some kind of gateway to fluidic space.

Number 7: The Borg

Borg drones seen in First Contact.

On the other side of the war with Species 8472 were the Borg! I also suggested Star Trek’s iconic cybernetic villains as a possible cause of the Burn last season, and despite seeing some ex-Borg in Picard Season 1, we haven’t really seen the faction proper in Star Trek since Enterprise Season 2 in 2003. Perhaps now is the right time?

Borg technology outpaced the Federation in the 24th Century by a considerable margin, and I’ve seen nothing to suggest that wouldn’t continue to be the case. The anomaly Stamets and Burnham discussed in the teaser may well be a natural phenomenon, but if it turns out to be a weapon, I can think of few other factions capable of creating and wielding one so massively powerful. Other Borg technology, such as their transwarp network, was known to have gravitational effects as well, so perhaps that’s another sliver of evidence.

The Borg were known to possess powerful technology.

This doesn’t really fit with the Borg’s usual modus operandi, and that is certainly a mark against it! But then again, the Borg are very adaptable, and travelling back in time several centuries is not exactly standard procedure for assimilating a planet either, yet that’s what they tried to do in First Contact! The gravitational anomaly could be the opening salvo of an attack; the artillery barrage to soften up the Federation before the Borg drones rush in to assimilate the survivors. The Borg certainly seem capable of doing something like this, and with the Federation having been on the back foot for more than a century as a result of the Burn, the Borg may have been using that time to build up and prepare for a large-scale invasion attempt.

We don’t know for sure if the Borg are still around in the 32nd Century, or if they still hope to one day conquer and assimilate the Federation. After more than 800 years, anything could have happened to them! However, it’s plausible that they still exist in similar form to how we last saw them.

The anomaly seemingly “attacking” both Federation and non-Federation targets could be indicative of an intelligence at work behind it. Space is huge after all, and the chances of it hitting a target as small as a starship, starbase, or planet regularly seems unlikely without some kind of explanation. Is it a force of nature drawn to energy, like the graviton ellipse mentioned above? Or is it a Borg weapon deliberately targeting Starfleet? The latter may seem unlikely, but it’s not impossible!

Number 8: The Burn

The Burn.

I certainly hope that Discovery Season 4 doesn’t just drop the Burn and proceed as though it never happened. After the cataclysm caused huge disruption to the Federation and the wider galaxy for over a century, I think we need to see a lot more of the consequences of that event before we even consider a “reset” of the Federation!

Perhaps what this anomaly will be is some kind of “mini-Burn,” affecting a smaller area. It could be a ripple effect of the original event, or otherwise connected to it in some way. Hopefully it won’t be caused by poor Su’Kal, who’s been through enough over the last 125 years! Though the Burn was presented as a unique event, perhaps it had lingering effects that are only just becoming known.

Su’Kal caused the Burn.

Season 4 needs to walk a line between acknowledging the events of Season 3 without dwelling on them the whole time. I understand that the writers and producers have other stories to tell in the 32nd Century beyond the Burn, but given how catastrophic it was I feel strongly that we need to see at least some of its lingering impact. Connecting the Burn to this new problem would create a degree of separation, allowing the season to go in new directions but without dropping the massive event entirely.

The Burn was a disaster which “caused dilithium to become inert,” and which caused active warp cores to explode. It wasn’t known to have gravitational effects, instead being some kind of shockwave that travelled through subspace. That could certainly count against it!

However, if this event were connected to the Burn in some other way, rather than being a direct result of Su’Kal’s outburst, perhaps it could be explained. I couldn’t even guess how such a connection could be made; it would be some kind of technobabble connecting the anomaly to dilithium and/or subspace. But it could be done, and it could be made to fit!

So that’s it. Eight very early theories about Discovery Season 4 and the mysterious “gravitational anomaly!”

Yes, Season 4 is scheduled to premiere this year!

As mentioned at the beginning, I quite like the idea of the series going down a “natural disaster” route, allowing the crew to solve a puzzle and unravel a mystery, rather than simply pitting them against a Federation-threatening adversary. Perhaps that will be what ultimately happens, but I think it’s at least possible we’re seeing some kind of attack or weapon as well. Time will tell!

The teaser was action-packed, and the new season looks to be in great shape. I think that there are possible downsides to another “huge galactic disaster” storyline so soon after resolving the Burn, in that it risks feeling tacked-on, derivative, or even anticlimactic if it’s an event smaller in scale. But despite that, if this anomaly is going to be one of the main storylines in Season 4, there’s a huge amount of potential.

Star Trek’s past didn’t provide the key to understanding the Burn last season. Will something we’ve seen before come into play in Season 4? Maybe!

Star Trek: Discovery Season 4 will debut on Paramount+ in the United States, and on Netflix in the United Kingdom and elsewhere, sometime later this year.
