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!

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 – Was there a last-second change for Tilly?

Spoiler Warning: There are spoilers ahead for Star Trek: Discovery Season 3, including the finale.

Something interesting happened as I was going back over the Season 3 finale of Star Trek: Discovery, and it turns out I’m not the only person who noticed it. After the main storylines of That Hope Is You, Part 2 were over, we were launched into a short epilogue which tried to wrap up a few other plot points from across the season. At the end of this epilogue, Burnham was promoted by Admiral Vance and assumed command of the USS Discovery.

On what we assume is her first outing as captain, Burnham arrives on the bridge to be greeted by an honour guard made up of senior officers, bridge crew, and other characters from the season. Among them was, of course, Tilly. If you were eagle-eyed during her brief moment on screen you might’ve spotted that she’s apparently been promoted to the rank of lieutenant – a well-earned promotion after her efforts throughout all three seasons of the series, and not what this controversy is about!

Tilly in the epilogue.

Look at the close-up image of Tilly above. She, along with the rest of the crew, have been given new uniforms. These uniforms are grey with a coloured stripe on the right of the tunic (or jacket) denoting departments. Tilly’s is blue, which makes sense because she’s a science officer. But do you see something off about the blue stripe on her uniform?

I confess that I didn’t at first. When I watched That Hope Is You, Part 2 for the first and second times, and again when I went back to the episode to capture still-frames for my review and theory post I completely missed it. The excitement and emotion of this moment, coupled with Tilly only being on screen for a scant couple of seconds, meant I missed it entirely – but look closely. The coloured stripe is clearly the result of digital post-production work.

A closer look at the blue stripe.

Looking at it now it seems painfully obvious. It wouldn’t be Discovery’s first digital effect that missed the mark in Season 3 – remember when Mirror Burnham was stabbed in Terra Firma, Part II? But it raises two quite interesting questions: what colour was her uniform originally, and why was it changed at the last minute?

It’s possible that this literally was a last-second change; the low quality of the texture used for the blue stripe may mean it was something thrown together in a matter of days, and this makes me wonder if the change is indicative of Discovery switching things up while the season was already in motion.

This stabbing looked pretty bad earlier in the season.

By the season finale, Tilly was acting first officer aboard Discovery. With the departure of Saru, Burnham has assumed command on what seems to be a permanent basis – but who will be her XO? That wasn’t addressed, but given their close relationship I wouldn’t be shocked if Discovery originally intended for Burnham to retain Tilly in that post also on a permanent basis. The awkward blue stripe may have been covering up a red stripe on her uniform – red denoting the command division.

Tilly becoming first officer was not a popular point, as far as I can tell from my limited interactions with the Star Trek fan community. It didn’t bother me personally, though seen in the context of the season as a whole I’d argue that perhaps Burnham’s ascent to the captaincy didn’t need the bump in the road of disobeying orders and losing her role as XO. But considering that there was some degree of pushback from fans to Tilly’s role, could that explain this seemingly slapdash digital work?

Saru appointing Tilly temporary first officer in Unification III didn’t sit well with everyone.

There are no immediately obvious first officer candidates among Discovery’s cast, yet in Season 4 the ship will certainly need one. A new character could be introduced, of course, or a secondary character could be promoted. But it seems at least possible that the original plan was for Tilly to stay in that post. If those plans were changed, the question is why?

The reaction from viewers seems a good bet, but considering that this was not a huge story point in Season 3 it seems at least a little peculiar for the producers and writers to go out of their way to undo it in such an odd fashion so late in the season. But it’s also possible that the storyline of Season 4 requires either a new first officer or for Tilly to be in a scientific role.

There could also be a simpler explanation: Tilly was originally wearing blue, but the low lighting on the bridge (which has been an issue at points for Discovery since Season 1) made her uniform look too dark in the finished shot. Rather than lighten the entire sequence the creative team tried to digitally recolour part of her uniform. Tilly is standing in a shadowy part of the set, so that’s a possibility.

However, that should have been known well in advance, and if it were changed for that reason it leaves the open question of why the finished effect looks so amateurish! It almost looks as though whoever worked on this retouching of her uniform simply pasted a single flat colour across the whole uniform stripe. If there had been time, you’d think that someone would have insisted that the digital effects team fix it before the episode was broadcast.

So it’s a minor mystery. What happened with Tilly’s uniform, and is it connected in any way to the minor backlash from some viewers to her role as first officer? We may never know!
