The final chapter of Flux is packed with a little too much plot, but it boils down to stopping the Sontarans from double-crossing two fellow villains, and the Doctor escaping from Swarm and his plans to destroy all of space. To do that, she risks her very existence. She also gets a warning about the future.
Chapter four of Flux features the return of the Weeping Angels, who may have made a little girl disappear. It’s much more complicated than that, as Claire is back but not feeling like herself. A side story with Bel also shows how this year’s Big Bads are causing major damage.
The second chapter of “Flux” features the Sontarans, who are using time travel to beat England in the Crimean War and take over the Earth in the present day.
Yaz is sent to a mysterious temple that seems to be regulating time, but Swarm also returns to destroy it…and maybe worse.
