Harry finds out that they will be learning to fly on broomsticks, but that Slytherin (and more importantly Draco) will be learning with them. At the lesson, Neville has an accident, and when Prof. Hooch goes to care for him, Malfoy steals something of Neville’s and taunts Harry into flying after him. As Harry swoops on the broom to catch the object, Prof, McGonagall catches him and takes him inside. She introduces him to a boy named Oliver Wood, and tells him that Harry would make a good Seeker in the game of Quidditch. At dinner, Harry is once again bullied by Malfoy, and Malfoy challenges him to a duel. Harry and Ron leave to meet around midnight, with Hermione following them, and they pick up Neville on the way. As they wait for Malfoy, Filch comes by looking for them. The students realize Malfoy has tricked them, and tipped off Filch. Running from Filch, they duck into a room, and discover a huge dog with 3 heads, right in front of them. They backtrack, and quickly return to their rooms. As they wonder about the 3-headed dog, Hermione shares her observation that the dog was sitting on top of a trapdoor. The dog is guarding something, and it is probably the package from Gringotts.
