Hermione: [after Hagrid gives Ron Scabbers back] I think you owe someone an apology.
Ron: Right. Next time I see Crookshanks, I'll let him know.
Hermione: [annoyed] I meant me!
Professor Snape: [taps the blank Marauder's Map with his wand] Reveal your secrets.
[writing appears on the map]
Professor Snape: Read it.
Harry: "Messrs. Mooney, Wormtail, Padfoot, and Prongs, offer their compliments to Professor Snape and..."
Professor Snape: Go on.
Harry: "... and request that he keep his abnormally large nose out of other people's business."
[about the Heir of Slytherin]
Hermione: I wonder who it could be?
Ron: [sarcastic puzzlement] Let's think... who do we know that thinks all Muggle-borns are scum?
Hermione: If you're talking about Malfoy...
Ron: Of course, Malfoy. You heard what he said. "You'll be next, Mudblood"!
Ron: Have you spoken to Hermione?
Harry: She should be out of hospital in a few days... when she stops coughing up fur balls.
Professor Snape: You were seen! By no less than seven Muggles! Do you have any idea how serious this is? You have risked the exposure of our world! Not to mention the damage you inflicted on Whomping Willow, that's been on these grounds since before you were born!
Ron: Honestly, Professor Snape, I think it did more damage to us.
Professor Snape: Silence! I assure you that were you in Slytherin and your fate rested with me, the both of you would be on the train home TONIGHT!
Lucius Malfoy: What's the use of being a disgrace to the name of wizard, if they don't even pay you well for it?
Arthur Weasley: We have a very different idea about what disgraces the name of wizard, Malfoy.
Lucius Malfoy: Clearly.
Hermione: Look at my face.
Ron: Look at your tail.
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!
Harry: Your bird, there was nothing I could do. He just caught fire.
Dumbledore: Oh, and about time too. He's been looking dreadful for days. Pity you had to see him on a burning day.
Weasley's wand causes devastation with the simplest spells. We'll be sending Potter to the hospital wing in a matchbox.Professor Snape
[to invisible Harry and Ron] If, er, anybody was looking for some stuff, then all they have to do is follow the spiders. Yep. That'd lead 'em right. That's all I have to say. Oh, and someone'll need ter feed Fang while I'm away.Hagrid
Ron, I should tell you, most Muggles aren't exactly accustomed to seeing a flying car.Harry
