Rubeus Hagrid: If that dolt of a cousin of yours, Dudley, gives you any grief... you could always... threaten him... with a nice pair of ears to go with that tail of his.
Harry Potter: But Hagrid, we're not allowed to do magic away from Hogwarts. You know that.
Rubeus Hagrid: I do. But your cousin don't, do he?
Harry Potter: Hagrid, who gave you the dragon egg? What did he look like?
Rubeus Hagrid: I don't know, I never saw his face. He kept his hood up.
Harry Potter: The stranger, though, you and he must have talked.
Rubeus Hagrid: Well, he wanted to know what sort of creatures I looked after. I told him. I said, "After Fluffy, a dragon's gonna be no problem."
Harry Potter: And did he seem interested in Fluffy?
Rubeus Hagrid: Well, of course he was interested in Fluffy. How often do you come across a three-headed dog, even if you're in the trade? But I told him. I said, "The trick with any beast is to know how to calm him." Take Fluffy, for example. Just play him a bit of music and he falls straight to sleep. (the trio looks at each other) I shouldn't have told you that. Where are you going? Wait!
Rubeus Hagrid: Ron, Hermione, you'll come with me.
Ron Weasley: Okay.
Rubeus Hagrid: And, Harry, you'll go with Malfoy.
Draco Malfoy: Okay. Then I get Fang.
Rubeus Hagrid: Fine. Just so you know, he's a bloody coward.
Rubeus Hagrid: Now, you listen to me, all three of you. You're meddling in things that ought not to be meddled in. It's dangerous. What that dog is guarding is strictly between Professor Dumbledore and Nicholas Flamel.
Harry Potter: Nicholas Flamel?
Rubeus Hagrid: I shouldn't have said that. I should not have said that...
Harry Potter: He killed my parents, didn't he? The one who gave me this. You know, Hagrid. I know you do.
Rubeus Hagrid: First, and understand this Harry because it's very important: Not all wizards are good. Some of them go bad. A few years ago... there was a one wizard who went as bad as he can go. His name was V... His name was V...
Harry Potter: Maybe if you wrote it down?
Rubeus Hagrid: No, I can't spell it. All right, Voldemort.
Harry Potter: Voldemort?
Rubeus Hagrid: It was dark times, Harry. Dark times. Voldemort started to gather some followers. Brought them over to the Dark Side. Anyone that stood up to him ended up dead. Your parents fought against him. But nobody lived once he decided to kill them. Nobody, not one. Except you.
