Exams and Other Worries
[Hermione] tries to discuss her [History of Magic] exam with [Ron], and [Harry] wonders about the twinges in his [scar]. Suddenly, though, he realizes that in order to get his [dragon] egg, [Hagrid] must have told the stranger about [Fluffy].
[Harry] confronts [Hagrid] about how he got his [dragon] egg, and [Hagrid] unwittingly tells them the same thing he told the stranger who gave him the egg: how to get past [Fluffy]. The trio then bolts for the castle.
Trying to find [Professor Dumbledore], [Harry], [Ron], and [Hermione] instead learn he is gone and confront [Professor McGonagall] about the [Philosopher's Stone]. She, however, is unconcerned and sends them back outside.
[Harry], [Ron], and [Hermione] resolve to guard the [third-floor corridor] and [Snape] for themselves, but [Hermione]'s attempt to guard the [staff room] is thwarted by [Snape] and [Ron] and [Harry] are caught outside the [third-floor corridor] by an angered [McGonagall].
Going After the Stone
Realizing that the enemy will be going after the [Philosopher's Stone] that night, [Harry] resolves to go after it himself, and [Hermione] and [Ron] resolve to go with him.
Getting ready to run after the [Philosopher's Stone], [Harry], [Ron], and [Hermione] are stopped by [Neville], and [Hermione] reluctantly performs [Petrificus Totalus] to get him out of their way.
The trio quietly walks to the [third-floor corridor], thwarting [Peeves] on the way, and find it already opened.
[Harry] and then [Hermione] play the [flute] to put [Fluffy] to sleep, and they and [Ron] drop through the trap door at the dog's feet.
Caught in [Devil's Snare], [Ron] starts to panic, [Hermione] realizes she needs a fire, and [Harry] and [Ron] remind her she can produce one. She lights a flame and the plant recoils, dropping them all to safety.
[Harry] leads [Hermione] and [Ron] into a room with three brooms and hundreds of [flying keys]. Together they corner and capture the correct key and use it to get through the next door.
