Amy: How can I remember them if they never existed?
Eleven: Because you’re special. That crack in your wall, all that time. The universe pouring into your head. You brought Rory back. You can bring them back too. You just remember. They’ll be there.
Amy: You won’t.
Eleven: You’ll have your family back. You won’t need your imaginary friend anymore. Amy Pond. Crying over me, eh? Guess what.
