Why do you think Karkaroff fled tonight? We both felt the Mark burn. We both knew he had returned. Karkaroff fears the Dark Lord’s vengeance. He betrayed too many of his fellow Death Eaters to be sure of a welcome back into the fold.”

He was going to admit that he had smuggled me from Azkaban.

There was complete silence now, except for Winky’s continued sobs. Then Dumbledore said, “And tonight...”
“I offered to carry the Triwizard Cup into the maze before dinner,” whispered Barty Crouch.
“Turned it into a Portkey. My master’s plan worked. He is returned to power and I will be honored by him beyond the dreams of wizards.”
