Chapter Summaries

Aaron concealed how he had attended two classes at once, but Hermione realized he had not used a Time-Turner and promised to keep his Thoughtform secret. At Hagrid’s Care of Magical Creatures lesson, the students met Hippogriffs, and Hagrid introduced Buckbeak.

• Hermione questioned Aaron about appearing in Arithmancy and another class at the same time, and he admitted he had been careless but refused to explain his Thoughtform.
• Hermione promised not to reveal Aaron’s secret and decided she would try to discover how it worked herself.

• Hagrid introduced Buckbeak and warned the students not to insult a Hippogriff before asking for a volunteer to approach it.

Hagrid taught the students how to approach Hippogriffs, but Draco insulted Buckbeak and was injured in its attack. Aaron had Abei secretly heal Draco enough to stabilize him, but Draco vowed to tell his father, leaving Hagrid worried about Buckbeak's fate.

• Harry bowed to Buckbeak, earned its acceptance, and flew around the grounds on its back.
• Aaron rode a Hippogriff without bowing because Abei's presence intimidated it, and Hagrid recognized the effect of magical-creature bloodline suppression.

• Aaron brought Abei to treat Draco's wound, but stopped the healing early and told Draco to appear injured so Madam Pomfrey would not become suspicious.
• Madam Pomfrey treated Draco, who threatened to tell his father, while Hagrid worried that Buckbeak would be punished.

After Draco recovered enough to return to class, Aaron helped Neville avoid poisoning his toad and was caught by Snape switching their potions. Snape then blackmailed Aaron into outshining Harry and the other Gryffindors in Lupin’s first Defense Against the Dark Arts lesson, using Dumbledore’s request to speak with Aaron as leverage.

Aaron learned why Sirius Black was believed to have betrayed Harry Potter’s parents and warned Draco, Crabbe, and Goyle not to tell Harry. He then accompanied Snape to observe Lupin’s first Defense Against the Dark Arts lesson, where the class prepared to face a Boggart.

Dumbledore and Snape discussed Aaron’s immense potential and whether he could be persuaded to oppose Voldemort, while Aaron remained unaware of their plans.
