Und noch ein paar Zitate:

Hermione Granger: You found it Neville, the room of requirement. It becomes available to anyone who really needs it.
Ron Weasley: Really, so if you really needed the toilet and you walked past?
Hermione Granger: Charming Ron, but yes that's right.

[Dumbledore has arrived at Harry's trial, which was moved up]
Cornelius Fudge: I don't think we informed you of the change in time.
Albus Dumbledore: By sheer luck, I arrived at the Ministry three hours early.

Severus Snape: [about his veritaserum] I have no other stocks. You have used it all interrogating students and used the last of it on Ms. Chang.

Ron Weasley: Hermione, you are truly the most wonderful person I have ever met and if I'm ever rude to you...
Hermione Granger: Then I'll know you've gone back to normal.

Dolores Umbridge: Wands away. There will be no need to talk.
Hermione Granger: No need to think is more likely

George Weasley: You know Fred, I always believed our future lay outside the realms of academic achievement.

Luna Lovegood: [petting a Thestral's beak] They're called Thestrals, they're really not bad but people avoid them because they're...
Harry Potter: …different...

Dolores Umbridge: Please, tell them I mean no harm.
Harry Potter: Sorry, Professor, but I must not tell lies.

Hermione Granger: Don't you know how Cho is feeling right now? Well, obviously, she's feeling sad, because of Cedric dying. Then she's feeling guilty for liking Harry, and worrying about what everyone else will say. And she probably can't work out her feelings towards Harry anyway, because he was the one who was with Cedric when he died.
Ron Weasley: One person can't feel all that at once, they'd explode.
Hermione Granger: Ron, just because you have the emotional range of a teaspoon!
