You're a parselmouth! Why didn't you tell us? I'm a what? You can talk to snakes! I know....

Ron: You're a parselmouth! Why didn't you tell us? Harry: I'm a what? Hermione: You can talk to snakes! Harry: I know. I mean, I accidentally set a python on my cousin Dudley at the zoo once. Once. But so what? I bet loads of people here can do it. Hermione: No, they can't! It's not a very common gift, Harry. This is bad. Harry: What's bad? If I hadn't told that snake not to attack Justin... Ron: Oh, that's what you said to it? Harry: You were there! You heard me! Ron: I head you speaking parseltongue. Snake language. Harry: I spoke a different language? But I didn't realize... how can speak a language without knowing I can? Hermione: I don't know, Harry, but it sounded like you were egging the snake on or something. Harry, listen to me. There's a reason the symbol of Slytherin house is a serpent. Salazar Slytherin was a parselmouth, he could talk to snakes too. Ron: Exactly! Now the whole school is gonna think you're his great-great-great-grandson or something. Harry: But I'm not! I can't be. Hermione: He lived a thousand years ago. For all we know, you could be.
