Rupert Grint: Ron Weasley
Malfoy : Ah, come to see the show?
Hermione : [shouts] You! You foul, loathsome, evil little cockroach!
[Hermione raises her wand at Malfoy. He backs against the wall, whimpering]
Ron : Hermione, no! He's not worth it.
[Hermione lowers her wand and turns away. Malfoy starts laughing, she spins around and socks him in the nose]
Vincent Crabbe : Malfoy! Are you okay? Come on, let's go!
Malfoy : [running away] Quick! Not a word to anyone! Understood?
Hermione : That felt good.
Ron : Not good, brilliant!
Sirius Black : Sorry about the bite, I reckon that twinges a bit.
Ron : A bit? A bit? You almost tore my leg off!
Sirius Black : I *was* going for the rat. Normally, I have a very sweet disposition as a dog. In fact, more than once, James suggested that I make the change permanent. The tail I could live with. But the fleas? They're murder.
Ron : [looking at Lupin who has just turned into a werewolf] Nice doggie... nice doggie...
Ron : She's gone mental, Hermione has. I mean, not that she wasn't always mental, but now it's out in the open for everyone to see!
Hermione : Headmaster, you've got to stop them! They've got the wrong man!
Harry : It's true, sir! Sirius is innocent!
Ron : It's Scabbers who did it.
Dumbledore : Scabbers?
Ron : He's my rat, sir. Well he's not really a rat. Well, he was a rat, he was my brother Percy's rat, but then they gave him an owl, and I got...
Hermione : The *point* is, we know the truth. Please believe us.
Professor Trelawney : Your aura is pulsing! Are you in the beyond? I think you are!
Ron : Sure...
Professor Trelawney : Look at the cup, tell me what you see!
Ron : Oh yeah... well, Harry's got a sort of wonky cross... that's trials and suffering. And, uh, that there could be the sun, and that's happiness, so... you're gonna suffer... but you're gonna be happy about it...
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!
[a rock thrown from outside hits the mug on the table; Ron and Hermione turn their heads, startled]
Hagrid : What was that?
[Hermione picks up the rock thrown]
Harry : [a rock thrown from outside hits the back of his head] Ow!
[turns and looks out the window]
Ron : I'm warning you Hermione! Keep that bloody beast of yours away from Scabbers or I'll turn it into a tea cozy!
Hermione : It's a cat, Ronald! What do you expect? It's in his nature.
Ron : A cat? Is that what they told you? It looks more like a pig with hair if you ask me.
Hermione : That's rich, coming from the owner of that smelly old shoe brush. It's alright, Crookshanks. Just ignore the mean little boy.
Ron : Bloody hell!
Dumbledore : Mysterious thing, time. Powerful, and when meddled with, dangerous. Sirius Black is in the topmost cell of the dark tower. You know the laws, Miss Granger. You must not be seen, and you would do well, I feel, to return before this last chime. If not, the consequences are too ghastly to discuss. If you succeed tonight, more than one innocent life may be spared. Three turns, should do it, I think.
[He starts to exit, turns back]
Dumbledore : Oh, by the way. When in doubt, I find retracing my steps to be a wise place to begin. Good luck.
Ron : What the bloody hell was that all about?
Ron : [Hermione is walking towards the werewolf Lupin] Hermione... bad idea... bad idea...
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.
Ron : Hermione, when did you get here?
[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.
Ron : Let me get this strait. Sirius Black has escaped from Azkaban to come after you?
Harry : Yeah.
Hermione : But they'll catch Black, won't they? I mean, everyone's looking for him.
Ron : Sure. Except no one's ever broken out of Azkaban before, and he's a murderous raving lunatic.
Harry : Thanks, Ron.
[about the newspaper clipping Ron was showing Harry and Hermione]
George Weasley : Not flashing that clipping again, are you, Ron?
Ron : I haven't shown anyone!
Fred Weasley : No, not a soul! Unless you count Tom.
George Weasley : The day maid.
Fred Weasley : The night maid.
George Weasley : The cook.
Fred Weasley : That bloke who came to fix the toilet.
George Weasley : And that wizard from Belgium!
Harry : What happened to me?
Ron : Well, you sort of went rigid. We thought maybe you were having a fit or something.
Harry : And did either of you two, you know, pass out?
Ron : No... I felt weird though, like I'd never be cheerful again.
Harry : But someone was screaming... a woman...
Hermione : No one was screaming, Harry.
[the train has stopped]
Ron : There's something moving out there.
Ron : Neville, you're supposed to stroke it!
Ron : [as Harry lays unconcious] Looks a bit peaky, doesn't he?
Fred Weasley : Peaky? What'd you expect him to look like? He fell fifty feet.
George Weasley : Yeah, c'mon, Ron. We'll walk you off the Astronomy Tower and see how you come out looking.
Harry : Probably a right sight better than he normally does.
[he opens his eyes to see everyone is with him]
Hermione : Harry! How are you feeling?
Harry : [he slips on his glasses] Brilliant.
Fred Weasley : Gave us a right good scare, mate.
Harry : What happened?
Ron : You fell off your broom.
Harry : Really? I meant the match. Who won?
[silence, no one is answering]
Hermione : No one blames you, Harry. The Dementors aren't meant to come on the grounds. Dumbledore was furious. After he saved you, he sent them straight off.
Ron : There's something else you should know, Harry. Your Nimbus - when it blew away? - it sort of landed in the Whomping Willow. And well...
[he hands Harry his broken broom stick]
Harry : [in the Shrieking Shack with Hermione trying to find Ron] Ron!
[runs into room]
Hermione : Ron, you're okay!
Ron : Harry, it's a trap! And he's a dog, he's an Animagus!
[Harry and Hermione look at paw prints, which leads them to looking at Sirius Black]
Hermione : If you're going to kill Harry you'll have to kill us, too!
Vincent Crabbe : [as Harry, Ron, and Hermione arrive] Look who's here.
Malfoy : Ah, come to see the show?
Hermione : You! You foul, loathsome, evil little cockroach!
Ron : [Hermione points wand at Malfoy, who staggers backwards into tree, wincing] Hermione, no! He's not worth it!
Vincent Crabbe : [Hermione lowers wand, while Malfoy laughs, making Hermione punch him in the face] Malfoy! Are you okay? Let's go!
[Malfoy, Goyle, and Crabbe run away]
Vincent Crabbe : Quick!
Malfoy : Run!
[he, Goyle, and Crabbe mutter various things while running away]
Hermione : That felt good.
Ron : Not good, brilliant!
[looks at Harry]
Professor Lupin : [as Snape points his wand at Sirius's throat] Severus, don't be a fool...
Sirius Black : He can't help it, it's habit by now.
Professor Lupin : Sirius, be quiet.
Sirius Black : Be quiet yourself, Remus!
Professor Snape : Listen to you two, quarreling like an old married couple...
Sirius Black : [in a mocking voice] Why don't yo run along and play with your chemistry set?
[Snape pushes wand harder on Sirius's throat]
Professor Snape : I could do it, you know. But why deny the Dementors? They're so longing to see you... do I detect a flicker of fear? Ah, yes, the Dementor's Kiss. One can only imagine what that must be like to endure. It's said to be nearly unbearable to witness, but I'll do my best.
[Harry unnoticeably pulls Hermione's wand out of her pocket]
Sirius Black : Severus, please!
Professor Snape : After you.
[gestures Sirius toward door]
Harry : [to Snape] Expelliarmus!
[Snape flies backwards onto a bed, unconscious]
Ron : Harry! What did you just do?
Hermione : You attacked a teacher!
Harry : [to Lupin] Tell me about Peter Pettigrew!
Professor Lupin : He was at school with us! We thought he was our friend!
Harry : No, Pettigrew's dead!
[whirls around at Sirius]
Harry : You killed him!
Professor Lupin : [jumps in front of Sirius] No he didn't! I thought so, too until you mentioned seeing Pettigrew on the map!
Harry : The map was lying, then!
Sirius Black : That map never lies! Pettigrew's alive! And he's right there!
[points at Ron]
Ron : Me? He's mental!
Sirius Black : Not you! Your rat!
Ron : Scabbers has been in my family for...
Sirius Black : Twelve years! Curiously a long life for a rat! He's missing a toe, isn't he?
Ron : So what?
Harry : [about Ron's rat missing a toe and being Peter Pettigrew] All they could find left of Pettigrew was his...
Sirius Black : Finger! But then the coward cut it off so they would think he was dead! And then he transformed into a rat!
Harry : Show me.
[Sirius tries to take the rat from Ron, but Ron holds onto it]
Harry : Give it to him, Ron.
Ron : What are you trying to do to him?
[Sirius finally gets a hold of the rat]
Ron : Scabbers! Leave him alone!
[tries to run toward Sirius, but Hermione holds him back]
Ron : Get off him! What are you doing?
[Sirius drops the rat, which runs while Sirius finally transforms it into Peter Petitgrew]
Peter Pettigrew : [realizes he's not a rat anymore] Remus, S-Sirius? My old friends!
[runs toward the door, but Lupin and Sirius block him]
Peter Pettigrew : Harry, l-look at you!
[walks toward Harry]
Peter Pettigrew : You look so much like your father! Like James, we were best friends!
Sirius Black : How dare you speak to Harry!
[Pettigrew scowls and runs away from Sirius]
Sirius Black : How dare you talk about James in front of him!
Professor Lupin : You sold James and Lily to Voldemort, didn't you?
Peter Pettigrew : I didn't mean to! The Dark Lord. You have no idea the weapons he possesses! Ask yourself, Sirius! What would you have done? What would you have done?
Sirius Black : I would have died!
[Pettigrew crawls under piano]
Sirius Black : I would have died rather than betray my friends!
Peter Pettigrew : [runs over to Harry, whispering to him] Harry, James wouldn't have wanted me killed! Your dad... your dad would have spared me! He would shown me mercy...!
[Lupin and Sirius yank him off Harry]
Sirius Black : You should have realized, Peter, that if Voldemort wouldn't kill you we would!
[he and Lupin pull out their wands and point them and Pettigrew]
Sirius Black : Together!
Harry : No!
Professor Lupin : Harry, this man is...
Harry : I know what he is, but we'll take him to the castle.
Peter Pettigrew : Bless you boy, bless you!
[kneels to Harry]
Harry : Get off me! I said we'll take you to the castle. After that, the dementors can have you.
