Chapter 11 - "Quidditch" - In which [Snape] takes [Harry]'s book, leading to [Harry] seeing [Snape]'s injured leg. Harry's first [Quidditch] match against [Slytherin] in which someone jinxes his broom but he catches the [Snitch] and wins anyway. [Hagrid] later lets a secret slip.
Halloween and the Troll
A group of [Hogwarts] teachers rushes in to find the [troll] knocked out, and [Hermione] lies about why the trio was going after it. [Professor McGonagall] takes [points] away from her, but awards points to [Harry] and [Ron] for saving her and knocking it out.
[Harry], [Ron], and [Hermione] walk back up to [Gryffindor Tower] in silence, and before heading to bed say a quick "thanks" to each other, sealing their friendship.
As time passes and the first [Quidditch] match approaches the weather cools, [Gryffindors] cheer and jeer [Harry] about the upcoming match, and [Hermione] loans [Harry] [Quidditch Through the Ages].
[Snape] spots [Harry] with [Quidditch Through the Ages] and nastily takes it from him and, [Harry] notices, limps away across the courtyard.
A restless [Harry] decides to try to find [Snape] and get his book back, but accidentally walks in on [Snape] and [Filch] binding Snape's injured leg and talking about the [three-headed dog], convincing [Harry] and [Ron] (but not [Hermione]) that he's trying to get into the [third-floor corridor].
Harry's First Quidditch Match
On the morning of his first [Quidditch] match, [Harry] sits at breakfast but is unable to eat anything out of nerves.
The [Gryffindor] and [Slytherin] [Quidditch] teams prepare for their first match - [Hermione], [Ron], and the [Gryffindor] boys settle into the stands, [Harry] listens to [Oliver Wood]'s speech, and [Madam Hooch] asks for a clean, fair game before blowing the whistle.
The first [Quidditch] match of the year begins: [Lee Jordan] calls the match, [Hagrid] arrives to sit with [Ron] and [Hermione], and [Harry]'s broomstick suddenly begins acting up. [Hermione], thinking it's [Snape]'s doing, sets his cloak on fire, and [Harry] recovers just in time to catch the [Snitch] in his mouth and win the match.
[Harry], [Hermione], and [Ron] sit in [Hagrid's hut] after the [Quidditch] match, celebrating [Gryffindor]'s victory and discussing [Snape], [Fluffy], and thanks to a slip-up from [Hagrid], [Nicholas Flamel].
