Chapter Summaries

William and Hermione investigated Barty Crouch’s death by reviewing memories and concluded that his son, Barty Crouch Jr., had survived by switching places with his mother. They left to tell Dumbledore and Minister Fudge, while William claimed he had evidence to prove their theory.

• William and Hermione used a Pensieve to review the hostages’ memories and discovered that Crouch had not been in the room during the kidnapping.
• William and Hermione considered whether Crouch had escaped earlier or been the kidnapper, but William rejected the idea that Crouch would free Death Eaters.
• William and Hermione reviewed memories of Crouch’s son’s trial and his parents’ visits to Azkaban, noticing that Mrs. Crouch acted strangely after seeing her son.
• William and Hermione deduced that Mrs. Crouch had switched places with her son, allowing Barty Crouch Jr. to escape while Crouch imprisoned his wife.
• William and Hermione concluded that Bertha had discovered the secret and that Crouch had erased her memory, then set off to tell Dumbledore and Minister Fudge.

William and Hermione argued that Barty Crouch had been murdered and that Barty Crouch Jr. was still alive, while Minister Fudge resisted their claims. William used Judy Crouch’s inability to summon Winky to show that another Crouch had inherited the family estate, leaving Fudge confronted with evidence that Barty Crouch Jr. survived.

• William brought Judy Crouch to the Headmaster’s Office and asked her to summon Winky, but she could not.
• William explained that Judy would have inherited the Crouch estate and Winky if Barty Crouch Jr. were dead, so her failure to summon Winky indicated that another Crouch had a stronger inheritance claim.
• Dumbledore praised William’s reasoning as Fudge fell silent.

After Barty Crouch Jr.’s survival was confirmed, Fudge ordered a search but refused to cancel the Third Task, while William and Hermione worried that Voldemort had found Crouch.

William realized that a House-elf may have taken Harry out of Hogwarts, leaving him unable to investigate Harry’s death while trapped in the time loop. He and Hermione sought Sir Cadogan for information about the Lady of the Lake, but his antics left William doubting the legends about King Arthur and Merlin.

• William persuaded Cedric to visit the Merpeople and summon Vivian, and Cedric jumped into the Black Lake with a Gillywater Potion.

• William realized Vivian had targeted the red and white dragons, using the Holy Grail as a distraction, and stopped her from taking both dragons.
• Dumbledore proposed another deal, and William revealed that the Goblin Gem Vivian had received was a fake made with Dumbledore's wand.
• Vivian agreed to trade a way out of Hogwarts for the real Goblin Gem and used her magic to transfer the bronze ring's connection from the castle to a trident.
• William caught the trident despite the burning pain, then gave Vivian the gem and told her she could remain trapped for another thousand years.
• Vivian warned William that he would need to bring her the red dragon in a future loop if he wanted to leave Hogwarts again, then drifted away with the gem.

William used the time loop to confront Voldemort, but reached the graveyard before Voldemort had completed his resurrection. He fought off Voldemort’s attack and left him fleeing, while Harry’s identity and Barty Crouch Jr.’s deception came to light.
