Ginny Weasley: The Fat lady... she's gone!
Ron: Serves her right. She was a terrible singer...
Hermione: That's not funny, Ron!
Fred Weasley: Nice try Harry, but not good enough
Harry: Come on guys, I'm trying to get to Hogsmeade
Fred Weasley, George Weasley: We know
George Weasley: If you'll stop squirming, we have a better way...
Harry: Guys, come on...
Fred
Weasley: Awwh, bless him
George Weasley: Now Harry...
Fred Weasley, George Weasley: Come and join the big boys
Hermione: Beautiful day.
Ron: Gorgeous. Unless of course you've been ripped to pieces.
Harry: Ripped to pieces? What are you talking about?
Hermione: Ronald has lost his rat.
Ron: I haven't lost anything! Your cat killed him!
Hermione: Rubbish!
Ron: Harry, you've seen the way that blood thirsty beast of hers is always lurking about. And now Scabbers is gone!
Hermione: Well maybe you should learn to take better care of your pets!
Ron: Your cat killed him!
Hermione: Did not!
Ron: Did.
Hermione: Didn't.
Cornelius Fudge: As the Minister of Magic, it is my duty to inform you, Mr. Potter, that earlier this evening your uncle's sister was located a little south of Sheffield, circling a chimney stack. The Accidental Magic Reversal department was dispatched immediately, she has been properly punctured and her memory modified. She will have no recollection of the event whatsoever so
that's that and no harm done. Pea soup?
Harry: No, thank you. Minister?
Cornelius Fudge: Yes?
Harry: I don't understand.
Cornelius Fudge: Understand?
Harry: I broke the law. Underage wizards aren't allowed to use magic at home.
Cornelius Fudge: Come now
Harry, the Ministry doesn't send people to Azkaban for blowing up their aunts.
Professor Snape: Potter, what are you doing wandering the corridors at night?
Harry: Nothing... I was sleepwalking.
Professor Snape: How extraordinarily like your father you are Potter, he too was exceedingly arrogant, strutting about the castle.
Harry: My Dad didn't strut, and nor do I. Now, if you don't
mind, I'd appreciate it if you could lower your wand.
[Hermione looks at Ron's broken leg, and they flirt by mimicking Malfoy and Pansy Parkinson]
Hermione: Ow! That looks really painful.
Ron: It's sorta painful. They uh, they might... chop it.
Hermione: I'm sure Madame Pomfrey will fix it in a heartbeat.
Ron: It's too late, it's ruined. It'll have to be
chopped off.
Harry: [about the Marauder's Map] Professor, just so you know I don't think that map always works. Earlier it showed someone in the castle... someone I know to be dead.
Professor Lupin: Oh really, and who might that be?
Harry: Peter Pettigrew.
Professor Lupin: [looking stunned] That's not possible.
[the Fat Lady has finally let them into Gryffindor Tower; both Harry and Seamus are talking at the same time]
Harry: She's still doing it, after three years, I mean...
Seamus Finnegan: I can't believe she still does that...
Harry, Seamus Finnegan: [together] She can't even sing!
Mr. Arthur Weasley: Harry, there are some within the Ministry who would strongly discourage me from divulging what I'm about to reveal to you, but I think that you need to know the facts. You are in danger. Grave danger.
Harry: Has this anything to do with Sirius Black?
Mr. Arthur Weasley: What do you know about Sirius Black, Harry?
Harry: Only that he's escaped from Azkaban.
Mr. Arthur Weasley: Do you know why? Thirteen years ago, when you stopped...
Harry: - Voldemort...
Mr. Arthur Weasley: - don't say his name.
Harry: Sorry.
Mr. Arthur Weasley: When you stopped You-Know-Who, Black
lost everything. But to this day, he still remains a faithful servant. And his mind you are the only thing that stands in the way of You-Know-Who returning to power. And that is why he has escaped from Azkaban. To find you...
Harry: And kill me.
Mr. Arthur Weasley: Harry, I want you to swear to me that whatever you might hear, you won't go looking
for Black.
Harry: Mr. Weasley, why would I go looking for someone who wants to kill me?
Professor Lupin: Why do you look so miserable, Harry?
Harry: None of it made any difference. Pettigrew escaped.
Professor Lupin: Didn't make any difference? Harry, it made all the difference in the world! You helped discover the truth. You saved an innocent man from a terrible fate. It made a great deal of difference.
Harry: Tell me about Peter Pettigrew!
Professor Lupin: He was at school witth us, we thought he was our friend.
Harry: No, Pettigrew's dead.
[to Sirius]
Harry: You killed him.
Professor Lupin: No he didn't! I thought so too, until you mentioned seeing Pettigrew on the map.
Harry: The map was lying, then.
Sirius Black: The map never lies! Pettigrew's alive.
Harry: You were right, Hermione! It wasn't my dad I saw earlier! It was me! I saw myself conjuring the patronus before! I knew I could do it this time, because... well, because I'd already done it! Does that make sense?
Hermione: No! But I DON'T LIKE FLYING!
[screams as Buckbeak dives]
Harry: Now what?
Hermione: We save Sirius.
Harry: How?
Hermione: No idea.
