The Next Doctor The Doctor lands his TARDIS in London on Christmas Eve, 1851. Overhearing cries for help, he encounters a man calling himself "The Doctor" and his companion Rosita, attempting to capture a Cybershade. The Cybershade escapes the trio. The Doctor, in talking to the man, comes to believe he may be a future incarnation of himself, who is suffering from amnesia. The man, dubbed the Next Doctor, takes the Doctor to a nearby house of a recently deceased reverend, believing him tied to a series of disappearances around London and the Cybershade. Inside, they discover a pair of Cybermen data-storage infostamps, which the Next Doctor recalls holding the night that he lost his memories. The two are attacked by Cybermen and the Doctor attempts to fight them off with a cutlass, but the Next Doctor kills them using electrical discharge from the infostamps.
