Arc 28The Tournament and the Time Loop
William uncovered Barty Crouch Jr.’s escape and the truth behind the apparent deaths during the Third Task, then used repeated loops to investigate Merlin and bargain with Vivian. He followed the disguised Harry to Voldemort’s hideout, where Voldemort escaped after William confronted him.
- William and Hermione uncovered that Barty Crouch Jr. had escaped Azkaban by switching places with his mother, but Fudge dismissed their evidence until Judy Crouch’s inability to summon Winky supported their deduction.
- During the Third Task, Cedric found Krum using the Cruciatus Curse on Ron, and the boys appeared to kill each other with deadly spells.
- The Ministry declared Harry and Krum dead, while William learned from Dumbledore that Voldemort had summoned the Death Eaters and was told to investigate without making Voldemort’s return his goal.
- William used the time loop to study magic and experiment, including making Lucius fall in love with Arthur Weasley, while Hermione helped him test the Opal Necklace.
- William and Hermione questioned Sir Cadogan and learned that Merlin had defeated Morgan le Fay, survived, and vanished, leading William to recognize the dragons as the ones from the tournament.
- William bargained with Vivian for a way to leave Hogwarts, released the white dragon, and stopped her from taking both dragons before trading her a real Goblin Gem for a trident linked to his loop magic.
- William followed Winky to a graveyard, where Krum’s disguise fell away and revealed Harry, exposing that Barty Crouch Jr. had switched the boys and staged their deaths.
- Wormtail attacked William, but William subdued him and confronted Voldemort in his frail body, and Voldemort destroyed his own body to escape and vowed to kill William after returning.
