Who will be the Survivors of the Flux and what will be left of them?
Two episodes down, with four to go, the BBC are still revealing titles of future chapters of Doctor Who: Flux. The penultimate episode of Series 13 will be Chapter Five: Survivors of the Flux. It’s airing on the 28th of November, and you can check out the official synopsis below:

Doctor Who: Flux – Chapter Five: Survivors of the Flux
As the forces of evil mass, the Doctor, Yaz and Dan face perilous journeys and seemingly insurmountable obstacles in their quest for survival.
Unsurprisingly, as the episodes get closer to the end of the story, the descriptions become vaguer. And after the Lopari, the Sontarans, the Weeping Angels, what could possibly be next? And how far have the Ravagers’ plans to reign in Hell advanced? Well, the synopsis for Survivors of the Flux hints that the impossible has happened; the Ravagers have won, and the Flux has destroyed most of the universe. The plural use of ‘journeys’ also suggests that, as with War of the Sontarans, the Doctor, Yaz, and Dan will be split up with their own paths to follow. Meanwhile, we don’t know the exact timeslot for Chapter Five yet, but we can assume it will be start sometime between six o’clock and half six, as with the installments so far.

Doctor Who: Flux continues this Sunday at 6.30pm on BBC One, and on BBC America in the US, with Chapter Three: Once, Upon Time
“Time is beginning to run wild”. On a planet that shouldn’t exist, in the aftermath of apocalypse, the Doctor, Dan, Yaz and Vinder face a battle to survive.
