27. "The Time of Angels"/"Flesh and Stone" - Amy becomes infected when a Weeping Angel imprints on her mind. How is she cured?
From Quiz "Doctor Who" - Series 5
Answer:
The Weeping Angels are erased from time
Receiving a message from River Song, the Doctor and Amy have to head to the planet Alfava Metraxis to find her and the recently-crashed Byzantium spacecraft. As it turns out, a Weeping Angel has been stored in the cargo bay, and the leaking radiation will only make it stronger. In fact, its strength is enough to allow the Weeping Angel to emerge from a video loop, without a physical form, and when Amy looks into its eyes it imprints on her brain. Things only worsen when the Doctor, River Song, and Amy head into a labyrinth to find it populated almost entirely by Weeping Angels; it takes inverting gravity and heading into the Byzantium through an exit hole to get any distance, and even then they find themselves trapped. In the control room, after opening a path into a forested oxygen factory, the Doctor finds that Amy is infected with the image of a Weeping Angel and must keep her eyes closed, and a crack in the wall-- identical to the one from Amy's bedroom-- is leaking time energy. All of this proves troubling, and the Doctor can only save Amy and River using teleportation and shifts in gravity, forcing the Angels to fall into the time crack and get erased from time. This, fortunately, seals the crack...for now. After the adventure, Amy and the Doctor go back to Amy's present day and she reveals that she plans to get married in the morning. The Doctor, however, finds that her wedding date is also the date of a major time explosion.
