This Thursday, the fourth season finale of Star Trek: Discovery will finally arrive. Paramount+ has yet to release a trailer or preview images. We do know that Vance and Tilly will appear, as they were spotted in the mid-season trailer. Otherwise, we are left to our imaginations. Over the season we have been speculating and theorizing, which included a Voyager supposition, a Gilligan hypothesis, and a Cosmos thesis. But why stop there? With a number of mysteries and plotlines still going, there is room for even more speculation. Here are some spinning around our heads… and we know some may contradict others.
Book will be the key to getting through to Species 10-C
As a Kwejian, Cleveland “Book” Booker has shown an ability to connect empathically with certain planets and animals. The fundamental challenge demonstrated in the latest episode (“Species 10-C”) was finding a way to communicate with the powerful race behind the DMA. Progress has been made, but time is running out as the DMA is about to wipe out both Earth and Ni’Var. One possible way to reach them could be for Book to make a connection and get 10-C to fully understand what they have done and get them to shut off the DMA. This reaching out to 10-C could be how he stops Tarka, and redeems himself.
Book’s necklace will be important
In the first episode of the season, we saw a coming of age ritual which included taking sap from “the World Root” of Kwejian and combining it with “the blood of your family” into an amulet. After the ritual, you wear the amulet to “carry us and Kwejian with you.” In season four Book started wearing his amulet again for the first time in a long while. Communicating via molecules is important to Species 10-C, so perhaps there is something in the amulet that could help communicate with 10-C, and also help them understand what they have done. Perhaps with their immense power, 10-C could use this amulet and what it contains to help restore Kwejian in some way.
Rillak will stay with 10-C
Call this our Bailey conjecture, but one way to find common ground with 10-C will be for someone to stay behind to act as an ambassador for the galaxy. Who better than President Rillak, who is an accomplished diplomat and has dedicated herself all season to bringing the galaxy together to face this crisis. She made sure to hand over power to the (unseen) vice president before she headed through the Galactic Barrier with the Discovery crew, so she knew she might not be coming back.
Tarka will make it to Oros’ universe, but maybe not to Oros
In the second half of the season, the mad scientist Ruon Tarka has emerged as a major adversary, dragging Book into his plan to strike at the DMA and 10-C and going up against the plan for first contact. However, unlike villains from past seasons like Kor, Mirror Lorca, Control/Leland, and Osyraa, Tarka has been presented as a sympathetic figure with an understandable motivation who may not deserve to die. He seems to be acting out of grief over the loss of his only true friend Oros, and has become obsessed with reuniting, seeing the power of the DMA as his only way. Perhaps someone will finally be able to get him to see the error of his ways in the finale, pulling him back from the brink. But in the end, Species 10-C may be moved by his love for Oros, and send him to that other universe, unless Oros is already hanging out with Species 10-C somewhere in that hyperfield… what a twist that would be? In another possible twist (we’ll call the Burgess Meredith conundrum) Tarka doesn’t find that universe to be what he expected or doesn’t find Oros waiting for him. Perhaps he will end up utterly alone in a cold unforgiving alternate universe, as a penance for his total lack of caring about the consequences of his actions.
T’Rina + Saru = Love Molecule
Since first meeting in season three, there has been a spark between Saru and President T’Rina of Ni’Var. This storyline has blossomed throughout season four, with Saru getting help from his wingman Dr. Culber, and even some Vulcan dating advice from Captain Burnham. This will all come to fruition in the finale, with the pair expressing their feelings and even doing that thing Vulcans do with their fingers to express their love.
Someone on the Discovery is not going to make it
While there has been a lot of death and destruction this season, Book is the only character who has suffered any kind of personal loss. To keep the stakes high, someone is probably going to die. But characters like Burnham, Saru, Stamets, and Adira are almost certainly protected by plot armor. The same is likely true of the bridge crew, but then again, there is the new guy Christopher, who has been around enough to qualify as more than just a red shirt but not long enough to be a shock to the system. And of course, there are a few other named characters that wouldn’t be a major loss… but there would be riots if a single scale on Linus is harmed.
Dr. Hirai will have a snack
Linguistics expert Dr. Hirai has been an interesting addition to the latter part of the season. Even with his gruff demeanor, he means well, and he has been an important part of figuring out how to communicate with 10-C. And in every episode he has been in, he has been consistently snacking. So, like Michael Burnham saving the galaxy, inspirational speeches being made, and people hugging, this prediction seems like a no-brainer.
