Dumbledore: People change in the maze. Oh, find the cup if you can. But be very wary; you could just lose yourselves along the way.
Luna Lovegood: I've never been to this part of the castle. Well, not awake. I sleepwalk, you see. That's why I wear shoes to bed.
Horace Slughorn: Thank you for the pineapple, you're quite right, it is my favorite - but how did you know? Tom Riddle - Age 16: Intuition.
Hermione Granger: He really is out there, isn't he? We've got to be able to defend ourselves. And if Umbridge refuses to teach us how, we need someone who will.
Sirius Black: This is my parent's house. I offered it to Dumbledore as headquarters for the Order. It's about the only useful thing I've been able to do.
Hermione Granger: That foul, evil old gargoyle! We're not learn how to defend ourselves, we're not learning how to pass our O.W.L.s. She's taking over the entire school!
Hermione Granger: [about the mass breakout from Azkaban] Dumbledore warned Fudge this would happen. He's going to get us all killed because he can't face the truth.
Albus Dumbledore: It was foolish of you to come here tonight, Tom. The Aurors are on their way. Lord Voldemort: By which time I shall be gone, and you... shall be dead!
Dumbledore: Only a person who wanted to find the Stone - find it, but not use it - would be able to get it. That is one of my more brilliant ideas. And between you and me, that is saying something.

Draco Malfoy: [picks up Neville's Rememberall] Did you see his face? Maybe if the fat lump had given this a squeeze, he'd have remembered to fall on his fat ass.
Caretaker Argus Filch: A pity they let the old punishments die. Was a time detention would find you hanging by your thumbs in the dungeons. God, I miss the screaming.
[first lines] Professor McGonagall: [as a cat] Mraow! Dumbledore: I should have known that you would be here, Professor McGonagall. [Professor McGonagall transfigures into her human self]

Harry: Its hard to believe it was just last Christmas that Harmony and I changed the world. And we didn't mean to and it didn't last long. You know a thing like that can't.
Harry: [to himself] And yeah, looking back, I maybe should've said something, told her I wasn't really a nipple - DETECTIVE, detective. Uhm, sorry...
[from trailer] Harry Hart: [Quoting William Horman] "Manners maketh man." Do you know what that means? Then let me teach you a lesson.
