The Flux is Coming

The Flux is Coming... was a prelude to Doctor Who: Flux, teasing the titular Flux through an in-universe distress call from the Thirteenth Doctor. The story was also the first appearance of Dan Lewis as a companion, taking place after, but airing before, his coming aboard the TARDIS in the full-length television episode The Halloween Apocalypse. John Bishop's as-yet-unnamed character had earlier been revealed in an especially-shot minisode, Welcome to the TARDIS..., which aired after the credits of Revolution of the Daleks, taking place prior to his meeting the Thirteenth Doctor.
