Rubeus Hagrid: Who was Ron trying to curse, anyway?
Harry Potter: Malfoy. He called Hermione... Well, I don't know exactly what it means.
Hermione Granger: He called me a Mudblood.
Rubeus Hagrid: He did not.
Harry Potter: What's a Mudblood?
Hermione Granger: It means "dirty blood." Mudblood's a really foul name for someone who's Muggle-born. Someone with non-magic parents. Someone like me. It's not a term one usually hears in civilized conversation.
Rubeus Hagrid: See, the thing is, Harry, there are some wizards, like the Malfoy family... who think they're better than everyone else because they're pure-blood.
Harry Potter: That's horrible.
Ron Weasley: It's disgusting.
Rubeus Hagrid: And it's codswallop to boot. Dirty blood. Why, there isn't a wizard alive today that's not half-blood or less. More to the point, they've yet to think of a spell that our Hermione can't do. Come here. Don't you think on it, Hermione. Don't you think on it for one minute.
Draco Malfoy: You see, Weasley, unlike some, my father can afford the best.
Hermione Granger: At least no one on the Gryffindor team had to buy their way in. They got in on pure talent.
Draco Malfoy: No one asked your opinion, you filthy little Mudblood.
Ron Weasley: You'll pay for that one, Malfoy. Eat slugs!
Hermione Granger: You okay, Ron? Say something.
(Ron throws up slugs, Colin takes a photo)
Colin Creevey: Wow! Can you turn him around, Harry?
Lucius Malfoy: Mr. Potter. Lucius Malfoy. We meet at last. Forgive me. Your scar is legend. As, of course, is the wizard who gave it to you.
Harry Potter: Voldemort killed my parents. He was nothing more than a murderer.
Lucius Malfoy: You must be very brave to mention his name. Or very foolish.
Hermione Granger: Fear of a name only increases fear of the thing itself.
Arthur Weasley: Harry, you must know all about Muggles. Tell me, what exactly is the function of a rubber duck?
Dobby: Dobby has to protect Harry Potter. To warn him. Harry Potter must not go back... to Hogwarts School of Witchcraft and Wizardry this year. There is a plot, a plot to make most terrible things happen.
Dobby: Dobby has come to tell you... It is difficult, sir. Dobby wonders where to begin.
Harry Potter: Why don't you sit down?
Dobby: Sit down? Sit down? (starts crying hysterically)
Harry Potter: Dobby, I'm sorry. I didn't mean to offend you or anything.
Dobby: Offend Dobby? Dobby has heard of your greatness, sir... but never has he been asked to sit down by a wizard, like an equal.
Harry Potter: You can't have met many decent wizards then.
