• Daphne told Tris that Trelawney had predicted something bad for nearly everyone, and Tris dismissed the vague forecasts as ordinary misfortunes.
• Professor McGonagall began the Transfiguration lesson by introducing Animagi, a subject familiar to the class because she was one and they had seen her capture Peter.
• Professor McGonagall explained Animagi and demonstrated transforming into her animal form, then asked why the students seemed unusually unenthusiastic.

• Tris explained that his mental pressure had made the Hippogriffs bow, and Theodore asked how he had done it.

• The third-years entered Osgilia’s padded, spacious classroom and saw a setup that suggested they would finally receive practical lessons.

Professor Osgilia taught his class about Boggarts and introduced the Riddikulus Charm as a way to weaken them with laughter. He revealed a Boggart in a cabinet and invited a student to try the spell.

• Tris held back from teasing the embarrassed Draco as Neville took his place.

During Osgilia’s Boggart lesson, Tris let down his mental defenses and discovered that he feared a nuclear bomb, which he transformed into a balloon with Riddikulus. As Osgilia prepared to end class, Draco interrupted him.

• Osgilia found that the Boggart would not emerge while Tris kept his thoughts shielded, and asked whether he was using Occlumency.

Tris and Osgilia began a sparring match with Disarming Charms, and Osgilia tested the thirteen-year-old’s magical power and control. Tris used two wands and a modified shield to deflect Osgilia’s attack, then unleashed magical fire that Osgilia swallowed into a rift before Tris sent another Disarming Charm at him.

• Osgilia and Tris exchanged Disarming Charms, and Osgilia judged Tris’s magical power to be impressive but weaker than his own.

• Osgilia blocked Tris's Disarming Charm and counterattacked with nonverbal spells, but Tris cast rapidly with two wands while sustaining a tortoiseshell shield.

• After the classroom emptied, Osgilia shut the door and collapsed to the floor, panting.
• Draco asked Tris who had won, and Tris said neither had won because their stamina and magic had not been tested to exhaustion.

After Tris’s duel with Osgilia sparked Hogwarts students to try casting spells with two wands, Ron injured himself attempting the technique. Madam Pomfrey explained its dangers, while Osgilia continued to struggle with the same problem that Tris had overcome.

• Tris stopped sparring with Osgilia when no special mission appeared, and students across Hogwarts began practicing dual-wand magic.
• Ron tried casting spells with both hands at once and coughed up blood, so Tris and Harry carried him to the Hospital Wing.

• After Ron recovered, another Gryffindor student named Shutal was brought in vomiting blood while holding two wands.
• Osgilia practiced alone in the Defense Against Dark Magic classroom and wondered why his magic clashed when he sped up, unlike Tris’s.

After Gryffindor crushed Slytherin in Quidditch, Draco complained to Tris about Harry’s Firebolt and the prospect of Gryffindor winning a third consecutive cup. Tris dismissed the loss and considered watching the upcoming matches between Gryffindor, Hufflepuff, and Ravenclaw for entertainment.

• Draco threw down his Nimbus 2000 and One after Slytherin lost to Gryffindor, then complained to Tris.
