On tonight’s episode of Doctor Who, the Doctor takes off her conversion plate to avoid Swarm disintegrating her, but ends up splitting herself in three: one stays outside the universe, one joins Karvanista and Bel on the Lupari ship, and the other reunites with Dan, Yaz, and Jericho in the tunnels.
Through the course of the episode they discover that the Sontarans, having used Claire to find the time and location of the final Flux event, have sent out a broadcast trying to broker peace with the Daleks and the Cybermen, but it’s a ruse. They know that to stop the Flux, which is made of antimatter, they need to hit it with matter, and they plan to use their enemies to do it and the ships of the Lupari who they massacred to shield them, taking control of the entire universe.
Eventually the Doctor and her friends stop and exile the Grand Serpent, who was working with the Sontarans, and gain control of the Lupari fleet to shield them from the Flux. They disperse the rest of the Flux energy into Passenger, at the suggestion of none other than Diane, who along with Vinder was able to escape the prison and call for the Doctor. Unfortunately, Jericho can not transmat away from the Sontarans and is pulled into the Flux with them.
