The Halloween Apocalypse (TV story)

The Halloween Apocalypse, prefixed in various sources with either Flux or simply Chapter One, was the first episode of series 13 of Doctor Who, and formed the first chapter of the six-part serial Doctor Who: Flux.

This opening chapter introduced the Flux, a universe-breaking force which is bound for Earth, as well as Swarm, who escapes his confinement and "frees" his sister Azure from her earthly life. Dan Lewis also joins the TARDIS team, ending Yasmin Khan's largely unwritten solo travels with the Thirteenth Doctor.

The Doctor is revealed to have been pursuing Karvanista, the last living member of the Division, the order which erased her memories of having been the Timeless Child. This carries on from the revelations of 2020's The Timeless Children.

Synopsis
Halloween, 2021. A storm approaches. Something tears through space and time, undoing everything it touches. Who is the man who escapes his shackles? What about Dan got his captor's attention? Why have the Angels come? And what will remain of the Earth, when this night is done?

Story notes

 * When trying to release herself from the vocally locked handcuffs, the Doctor claims that her failure to open them might be to do with the fact that she was Scottish when she set them up, and proceeds to attempt a Scottish accent. According to the subtitles, she first tries to copy the voice of the Twelfth Doctor and then the Seventh Doctor.
