What is the summary for Chapter 10 of Harry Potter and the Sorcerer’s Stone?
A package arrives for Harry. It's a Nimbus 2000, and a note telling him to meet Oliver Wood, the captain of the Gryffindor Quidditch team.
When Harry meets Oliver, the captain explains the game and shows Harry the various balls involved. Harry's role is the Seeker. Impressed his Harry's flying skills, Oilver hopes to win the Quidditch Cup.
The students are learning a levitation spell. Hermione is very adept at using the spell, much to the chagrin of many of her classmates. When leaving class, Ron says that she is a "nightmare" and it's no wonder she doesn't have any friends. Hermione overhears him and hides herself in the girls' bathroom.
At the Hallowe'en feast, Quirrel rushes into the hall declaring that a troll is loose. Panic ensues and everyone is sent to their rooms. The boys remember that Hermione is in the bathroom and go to warn her.
When they get there, they can hear Hermione screaming. They try to distract the troll and rescue Hermione; Harry climbs on its back and sticks his wand up the troll's nose. Ron screams, "Wingardium Leviosa", and the troll's club rises into the air, knocking it unconscious. Teachers arrive, and McGonagall blasts the boys for taking on the troll themselves, but Hermione speaks up and says that going after the troll was her idea and that the boys had been trying to stop her. The boys become friends with Hermione.
