Doctor Who: Flux - 15 Huge Details We Just Learned About Series 13

10. Some Villains Will Appear In Multiple Episodes

This is a somewhat obvious detail considering the interconnected nature of the series, but it's an intriguing one nonetheless: Chibnall has mentioned that certain villains will "go across more than one episode."

We don't know which villains, mind you, but don't be shocked if the Weeping Angels, Ravagers, or Cybermen get more than one shot at exterminating the Doctor for good.

Based on certain pre-release information, there's also reason to believe that the Sontarans will be a multi-episode foe, but we'll just have to wait and see!
