One night, Harry and Krum are startled when a dishevelled Barty Crouch, Sr. emerges from the forest, mumbling nonsense and demanding to see Dumbledore. Harry runs for help, but when he returns with Dumbledore, they find Krum unconscious and Crouch missing. Harry learns more about the Crouches when he sees one of Dumbledore's memories in the Pensieve, a memory-storing tool. The memory shows Barty Crouch, Jr., a Death Eater, sentenced to Azkaban by his father for helping Bellatrix Lestrange torture Frank and Alice Longbottom, Neville's parents, into insanity.
The third and final tournament task involves navigating a labyrinth filled with magical obstacles. Harry and Cedric successfully help each other navigate the maze. They reach the Triwizard cup and agree to take hold of it simultaneously, making both of them winners. The Cup turns out to be a portkey that transports them to an old graveyard in Little Hangleton, where they see Pettigrew and a deformed Lord Voldemort. Pettigrew kills Cedric and ties Harry to the Riddle tombstone. He then uses a bone from Voldemort's father's grave, some of Harry's blood, and his own cut-off hand in a magical ritual that restores Lord Voldemort to a new body.
