Arc 9The Loop and the Summer House
William completed his time-loop training, killed the Basilisk, and returned to the moment of the Quidditch match before winning Ravenclaw the House Cup. He settled into a summer home with Hermione and Anne, trained Hermione, and prepared to begin his Animagus transformation while Anne received her Hogwarts letter.
- William investigated the forbidden area during the time loop, learned Ancient Runes, Apparition, and Occlumency, and repeatedly tested himself through dangerous challenges.
- Harry and Ron died in the trapdoor chamber, and William followed Harry as Voldemort revealed himself, killed him, and fled after Harry swallowed the Philosopher’s Stone.
- An eagle emerged from William’s ring and carried him through a whirlpool, ending the loop and returning him to the Quidditch match.
- William concealed the Basilisk in fog, blinded and killed it with a rune-enhanced sword, then argued with Snape over the venom as Dumbledore drove Voldemort away.
- William helped Ravenclaw win the Quidditch Cup and House Cup, finished his exams, and traveled home as Lucius Malfoy plotted to plant Tom Riddle’s diary on one of Arthur Weasley’s children.
- William brought Hermione, Anne, and Bobocha to his renovated summer home, Bag End, where Luna Lovegood soon became a regular visitor and took Hermione and Anne to see unicorns.
- William encouraged Hermione’s cooking, trained her in spellcasting and combat, and told her he would soon begin his Animagus transformation.
- Hermione agreed to stay with William during the transformation, and Anne arrived with her Hogwarts acceptance letter, which William laughed over after reading Dumbledore’s revisions.
