We watch "Death in Heaven" (Series 8, Episode 12) where the Doctor learns about Missy's plan (well... you couldn’t still expect to call her the MASTER could you? What with her lady parts and all...), Seb ‘squees’ yet is promptly disintegrated (see ya later Tenant stans), and Clara impersonates the Doctor (all I’m saying is a scarf woulda been nice). Whilst said cosplaying is occurring, the reanimated corpses of Danny Pink and Brigadier Lethbridge-Stewart save humanity from a fate worse than rotting in the ground. What? I’m an atheist... deal!
