Hermione Granger: Professor... I was wondering if you could tell us about the Chamber of Secrets.
Minerva McGonagall: Very well. You all know, of course... that Hogwarts was founded over a thousand years ago... by the four greatest witches and wizards of the age: Godric Gryffindor, Helga Hufflepuff... Rowena Ravenclaw and Salazar Slytherin. Now, three of the founders coexisted quite harmoniously. One did not.
Ron Weasley (to Harry): Three guesses who.
Minerva McGonagall: Salazar Slytherin wished to be more selective... about the students admitted to Hogwarts. He believed magical learning should be kept within all-magic families. In other words, pure-bloods. Unable to sway the others, he decided to leave the school. Now, according to legend... Slytherin had built a hidden chamber in this castle... known as the Chamber of Secrets. Though, shortly before departing, he sealed it... until that time when his own true Heir returned to the school. The Heir alone... would be able to open the Chamber... and unleash the horror within, and by so doing... purge the school of all those who... in Slytherin's view, were unworthy to study magic.
Hermione Granger: Muggle-borns.
Minerva McGonagall: Well. Naturally, the school has been searched many times. No such chamber has been found.
Hermione Granger: Professor? What exactly does legend tell us lies within the Chamber?
Minerva McGonagall: The Chamber is said to be home to something... that only the Heir of Slytherin can control. It is said to be the home... of a monster.
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.
