Ron: I'm Ron by the way, Ron Weasley.
Harry: I'm Harry. Harry Potter.
Ron: So ... so it's true! I mean, do you really have the ... the ...
Harry: The what?
Ron: [in a hushed tone] The scar?
[Harry shows him the scar on his forehead]
Ron: Mental that one, I'm telling you.
[After seeing Ron's queen destroy Harry's knight]
Hermione: That's totally barbaric!
Ron: That's wizard's chess.
Ron: You're a little scary sometimes, you know that. Brilliant. But scary.
Hermione: Ron, you don't suppose this is going to be like real wizard's chess, do you?
Ron: Yes Hermione, I think this is going to be exactly like wizard's chess.
Ron: It's you that has to go on, Harry. I know it. Not me. Not Hermione. You!
Harry: I think if he had the chance, he would have killed me tonight.
Ron: And to think, I've been worrying about my potions final.
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 worst, EXPELLED!
Ron: She needs to sort out her priorities!
