One month before the final task, Harry and Krum are talking when they encounter Crouch, who appears to have gone insane, but manages to tell Harry to get Dumbledore. Leaving Krum with Crouch, Harry fetches Dumbledore but returns to find Krum stunned and Crouch gone. Harry returns to preparing for the final task, a hedge maze. Inside the maze, Harry is forced to incapacitate Krum, who has been bewitched, to save Cedric. Working together, the two reach the cup. They agree to touch it at the same time, and doing so, discover that it is a Portkey that transports them to a graveyard. There, Peter Pettigrew kills Cedric and uses Harry's blood (along with his own hand and Tom Riddle Sr.'s bone) to resurrect Lord Voldemort.
