Harry: Good of you to get us out of trouble like that.
Ron: Mind you, we did save her life!
Harry: Mind you, she might not have needed saving if you hadn't insulted her.
Ron: What are friends for?
For your information Potter, Asphodel and Wormwood making a sleeping potion so powerful it is known as the draught of the living dead, a Beozar is a stone taken from the stomach of a goat and will save you from most poisons. As for Monkshood and Wolfsbane, they are the same plant which also goes by the name of Aconyte. Well, why aren't you all copying this down?Professor Severus Snape
Hermione: Look at you playing with your cards. Pathetic! We've got final exams coming up soon.
Ron: I'm ready! Ask me any questions.
Hermione: All right, what's the three most crucial ingredients in a Forgetfulness Potion?
Ron: I forgot.
Hermione: And what may I ask do you plan to do if this comes up in the final exam?
Ron: Copy off you?
Hermione: No, you won't! Besides, according to Professor McGonagall, we're to be given special quills bewitched with an anti-cheating spell.
Ron: That's insulting! It's as if they don't trust us!
Ron: Wingardium leviosa!
Hermione: Stop, stop stop! You're going to take someone's eye out. Besides, you're saying it wrong. It's Levi-OOO-sa, not Levio-SA
What happened in the dungeon between you and Professor Quirrell is a complete secret, so naturally, the whole school knows.Dumbledore
Harry: I swear I don't know. One second the glass was there and the next it was gone. It was like magic.
Uncle Vernon: There is no such thing as magic!
Hermione: Ron, you don't suppose this is going to be like . . real wizard's chess, do you?
[one of the giant white pawns crosses the board, and smashes the black pawn with a violent blow]
Ron: Yes, Hermione, I think this is going to be exactly like wizard's chess.
Hermione: You'll be okay, Harry. You're a great wizard. You really are.
Harry: Not as good as you.
Hermione: Me? Books and cleverness. There are more important things: friendship and bravery. And Harry, just be careful.
Hermione: Harry, no way! You heard what Madame Hooch said, besides, you don't even know how to fly!
[Harry ignores Hermione, giving Malfoy an evil look, he flies up. The class stare up at him]
Hermione: What an idiot!
Hermione: Stop moving, both of you. This is devil's snare! You have to relax. If you don't, it'll only kill you faster!
Ron: Kill us faster? Oh, now I can relax!
[explaining how to get past Fluffy] You just play a bit of music and he'll fall right to sleep... I shouldn't have told you that!Hagrid
Hermione: Now, if you two don't mind, I'm going to bed before either of you come up with another clever idea to get us killed. Or worse, expelled.
Ron: She needs to sort out her priorities
