We’d been feeling a little lost in Flux, but thankfully this week we’re watching series 13 episode 1, "The Halloween Apocalypse"! This is where it all began, so we’ll finally have all the context we’ve been missing. Just who are Swarm and Azure Ravagers? Does a mysterious Hat Man live on Mars, or in Liverpool? How many Sontarans does it take to control a sector? Is Bel the Doctor’s mom or whatever? Thankfully, at least one of these questions is finally answered. For the others, we’ll get them next time I’m sure!
