[after Lockhart reveals his ineptness at fighting the Dark Arts]
Ron: Is there anything you CAN do?
Gilderoy Lockhart: Yes, now you mention it. I'm rather gifted with Memory Charms. Otherwise, you see, all those wizards would have gone blabbing. And I'd never have sold another book.
Ron: Dad loves muggles. Thinks they're fascinating.
Tom Marvolo Riddle: Let's match the power of Lord Voldemort, Heir of Salazar Slytherin, against the famous Harry Potter.
Tom Marvolo Riddle: Haven't I told you? Killing Mudbloods doesn't matter to me any more. For many months now, my new target has been you.
[repeated line]
Hagrid: I shouldn't have told you that.
Gilderoy Lockhart: Professor Dumbledore has granted me permission to start this little dueling club, to train you all up, in case you ever need to defend yourselves, as I myself have done on countless occasions. For full details, see my published works.
The Sorting Hat: Bee in your bonnet, Potter?
Harry: I-I was- I was just wondering, if you put me in the right house?
The Sorting Hat: Yes, you were particularly difficult to place. But I stand by what I said last year: You would have done well in Slytherin.
Harry: You're wrong.
Gilderoy Lockhart: Harry, Harry, Harry. Can you possibly imagine a better way to serve detention, than by helping me to answer my fan mail?
Harry: Not really.
Gilderoy Lockhart: Fame is a fickle friend Harry. Celebrity is as celebrity does. Remember that.
Dobby: [Dobby stands between Harry and an advancing Lucius Malfoy] You shall not harm Harry Potter!
Lucius Malfoy: Avarda -
[Before he can finish, Dobby sends Malfoy flying with a wave of his hand]
Harry: [a rogue Bludger starts chasing Harry during the Quidditch match]
Ron: [Getting his wand out] I'll stop it!
Hermione: No! Even with a proper wand, it's too dangerous - you might hit Harry!
[Ron gets his wand out to levitate the sleeping draught cupcakes when Harry holds his hand out]
Harry: Ron, maybe I should do it?
[Ron looks at his wand]
Ron: [Resignedly] Yeah. Right.
[puts the wand away, as Harry gets his own wand out]
Draco Malfoy: My father did say this; it's been fifty years since the chamber has been opened. He wouldn't tell me who opened it, only that they were expelled. The last time the Chamber of Secrets was opened, a mudblood died. So it's only a matter of time before one of them is killed this time. As for me, I hope it's Granger.
Harry: You're running away? After all that stuff you did in your books?
Gilderoy Lockhart: Books can be misleading...
Harry: You wrote them!
Gilderoy Lockhart: My dear boy, do use your common sense! My books wouldn't have sold half as well if people didn't think *I'd* done all those things!
Filch: Well, take a good look lads. This night might well be the last you spend in this castle. Oh, dear, we are in trouble.
[about Crabbe and Goyle]
Ron: Maybe we could trick them into telling.
Hermione: Even *they* aren't that thick.
[Crabbe and Goyle eat the floating Sleeping Draught cupcakes]
Ron: How thick could you get?
Uncle Vernon: Oh no you don't, boy! You and that bloody pigeon aren't going anywhere!
[first lines]
[Hedwig wants to be let out of her cage]
Harry: I can't let you out, Hedwig! I'm not allowed to use magic outside of school. Besides, if Uncle Vernon...
Uncle Vernon: [yells] Harry Potter!
Harry: Now you've done it.
