History Recap / DoctorWhoS39E6FluxChapterSixTheVanquishers

** After having exiled Vinder in the backstory, the Grand Serpent is [[SeakedRoomInTheMiddleOfNowhere left stranded on a tiny remote asteroid]] for the rest of his life, with no planets visible for light years in any direction.

* ImmortalsFearDeath: Implied when Time tells the Doctor she will catch up with her, and it's implied not in the long term either. And this time there will be no regeneration to give her another life.

** After having exiled Vinder in the backstory, the Grand Serpent is left stranded on a remote asteroid for the rest of his life, with no planets visible for light years in any direction.

* ContinuityNod: Time was previously established as a godlike sentient being called an Eternal in the ''[[Literature/DoctorWhoNewAdventures Doctor Who New Adventures]]'' novels and the embodiment of temporal events, then an ally of the Seventh Doctor after she chose him as her champion, but the character was never made officially canon. This episode reveals that Time really can think for itself and have jurisdiction over certain events.

* MyFriendsAndZoidberg: The Sontaran commander offers the hand of friendship to all their enemies... except those stupid inferior [[ArchEnemy Rutans]], who will be crushed under the heel of Sontaran boots.

** What is the Bizarrchitecture floating house that the Doctor has been seeing in visions? It's a representation of her lost memories, which she's been glimpsing thanks to the psychic link with Swarm.

* ExploitedImmunity: The Sontaran's plan; lure the Cybermen and Daleks to the place where the Flux will cause the most damage with a fake offer of mutually assured survival, then use the anti-Flux shielding seized from the Lupari fleet to protect themselves while the Flux rips apart 2 of their most hated enemies.

* AssholeVictim: Tecteun shows utter disregard for the universe and wanted to wipe it clean with a final wave of the Flux, and is implied to be a brainchild of the Division that stole a chunk of the Doctor's memories. She appears to be kind on the surface, but her agenda is repugnant, as the final Flux event would kill everything in the universe. When Swarm dissolves her with his power to scatter beings into temporal oblivion, Tecteun isn't missed.

* AwesomenessByAnalysis: Diane has been able to figure out an impressive amount about how Passenger systems work merely by being interacting with her surroundings while trapped inside one of them. This allows her and Vinder to escape from the one they're trapped in and send a distress signal to the Doctor, and her suggestion to use the infinite space inside one to contain the Flux ends up saving the rest of the universe.

* ExplodingLeash: Karvanista has a poison injector implanted in his brain that will kill him if he discusses his work with the Division with the Doctor.

* BookEnds: A scene near the end of the episode mirrors the one near the start of "The Halloween Apocalypse" that first introduced the audience to Dan and Diana: Dan is impersonating a tour guide at the Museum of Liverpool and giving a speech to some tourists, he gets interrupted by Diane and tries to ask her out for a coffee.

* SummonBiggerFish: When a squad of Sontarans confront Yaz, Dan, Jericho and Williamson in the tunnels, Yaz opens a door which Williamson has plastered with labels reading CERTAIN DEATH and DO NOT ENTER. Whatever's on the other side of the door manifests as a series of red tendrils that kills the Sontarans.

* FaceDeathWithDignity: Professor Jericho, facing imminent death by Flux, simply closes his eyes.

* PrimalFear: Swarm deduces that the Doctor's greatest fear is destruction.

* WhamEpisode: Though most of the episode's consequences are implied rather than explicitly focused on, the story- and the five that preceded it- have a ''huge'' impact on the universe. While the Flux is stopped, [[AvertedTrope there is no]] ResetButton to undo the events, meaning that a big chunk of the universe is implicitly ''gone'' for the time. Most, if not all, of the forces of the Daleks, Cybermen, and Sontarans have been wiped out by the final Flux event. ''Time itself'' is officially revealed to be sentient and potentially malicious, leading to it being restrained by the Temple of Atropos. And the Doctor has access to a watch containing the memories of all her lost incarnations, although for now she has stored it away in the TARDIS so she won't be tempted to open it. And then there's Time's warning that once again, the Doctor's death is near, and unlike the Tenth Doctor's portent of doom, it seems that 13's future death will be permanent.

* BittersweetEnding: Dan is rejected by Di as a result of her trauma but joins the TARDIS crew properly, and the Doctor apologises to Yaz for closing her out, but cries when nobody is looking. Also, while Earth is safe much, if not '''most''', of the universe has been destroyed with no ResetButton in sight.
