We watch "The Return of Doctor Mysterio" (Series 9, Episode 14) where the Doctor travels to post 1920s New York City circa 1994 in order to fix the time conundrum created when he doomed Amy and Rory to die in the past of their future selves due to their deaths being a fixed point-in-time... oi vey! Whilst hopeful doom-fixing was occurring, Nardole was repaired to companion status, overly trusting Grant was made into an overly Super... let’s say... Man, and Lucy gets visited by The Ghost... of present Christmas. Oh, didn’t we say this was another Christmas episode with no guest-of-the-pod-Denise? Our bad.
