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.
