"[describing to Dumbledore about his dream of Voldemort, Wormtail and Barty Crouch Jr.] It was in the summer, before school. In the dream, I was in a house. And Voldemort was there, only he wasn't quite human. And Wormtail was there too. And (so was) Mr. Crouch's son. [Dumbledore: Have there been others like this dream?] Yes."
