Dumbledore: It takes a great deal of bravery to stand up to your enemies, but a great deal more to stand up to your friends.
Draco Malfoy: Think my name's funny, do you? No need to ask yours. Red hair... And a hand-me-down robe. You must be a Weasley.
Albus Dumbledore: Ah, Bertie Bott's Every Flavor Beans. I was most unfortunate in my youth to come across a vomit flavoured one. I must say since then I have lost my liking for them. But I think... I might be safe... with a nice toffee. [He has a bean.] Alas. Earwax.
Minerva McGonagall: Do you think it is wise to trust Hagrid with something as important as this?
Albus Dumbledore: Ah, Professor, I would trust Hagrid with my life.
Dumbledore: Also, our caretaker, Mr. Filch, has asked me to remind you that the third-floor corridor on the right-hand side is out of bounds to everyone who does not wish to die a most painful death.
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.
Ron: I think we've had a bad influence on her.
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.
Draco Malfoy: It's true then, what they're saying on the train. Harry Potter has come to Hogwarts.
Seamus Finnigan: I'm half and half. Me dad's a muggle; Mam's a witch. Bit of a nasty shock for him when he found out.
Percy Weasley: And keep an eye on the staircases. They like to change.
Harry: I swear I don't know. One minute the glass was there and then it was gone. It was like magic.
Uncle Vernon: There's no such thing as magic!
Harry Potter: I'm sorry, but what's curious?
Olivander: I remember every wand I've ever sold, Mr.Potter. Every single one. It's curious that you should be destined for this wand, when its brother gave you that scar.
Ron: Mental that one, I'm telling you.
