Harry: Ron!
Hermione: Ron. You're okay.
Harry: The dog. Where is it?
Ron: Harry, it's a trap. He's the dog. He's an Animagus.
Hermione: If you want to kill Harry, you have to kill us too!

Sirius: No. Only one will die tonight.
Harry: Then it'll be you!
Sirius: Are you going to kill me, Harry?
Lupin: Expelliarmus. Well, well, Sirius. Looking rather ragged, aren't we? Finally, the flesh reflects the madness within.
Sirius: Well, you'd know all about the madness within, wouldn't you ?I found him.
Lupin: I know.
Sirius: He's here.
Lupin: I understand.
Sirius: Let's kill him!
Hermione: No! I trusted you!And all this time, you've been his friend. He's a werewolf!That's why he's been missing classes.
Lupin: How long have you known ?Hermione: Since Professor Snape set the essay.
Lupin: Well, well, well, Hermione. You are the brightest witch of your age I've ever met.
Sirius: Enough talk, Remus!Come on, let's kill him.
Lupin: Wait!
Sirius: I did my waiting!Twelve years of it!In Azkaban!
Lupin: Very well. Kill him. But wait one more minute. Harry has the right to know why.
Harry: I know why. You betrayed my parents. You're the reason they're dead.
Lupin: No, Harry, it wasn't him. Somebody did betray your parents, somebody who, until quite recently, I believed to be dead!
Harry: Who was it, then ?
Sirius: Peter Pettigrew!And he's in this room!Right now!Come out, come out, Peter!Come out, come out and play!
Snape: Expelliarmus!Vengeance is sweet. How I hoped I'd be the one to catch you.
Lupin: Severus……
Snape: I told Dumbledore you were helping a friend into the castle. And now, here's the proof.
Sirius: Brilliant, Snape. You put your keen mind to the task and come to the wrong conclusion. If you'll excuse us. Remus and I have business to attend to.
Snape: Give me a reason. I beg you!
Lupin: Don't be a fool.
Sirius: He can't help it. It's habit.
Lupin: Be quiet.
Sirius: Be quiet yourself!
Snape: You two, quarrelling like an old married couple.
Sirius: Run along and play with your chemistry set!
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 ?Oh, yes. A dementors's kiss. One can only imagine what that must be like. It's said to be nearly unbearable to witness, but I'll do my best.
Lupin: Severus, please.
Snape: After you.
Harry: Expelliarmus!
Ron: Harry!What did you just do?
Hermione: You attacked a teacher!
Harry: Tell me about Peter.
Lupin: He was at school with us. We thought he was our friend!
Harry: No, Pettigrew's dead. You killed him!
Lupin: No, he didn't. I thought so too, until you mentioned Pettigrew on the map!
Harry: The map was lying, then.
Sirius: The map never lies!Pettigrew's alive!And he's right there!
Ron: Me? He's mental!
Sirius: Not you!Your rat!
Ron: Scabbers has been in my family for……
Sirius: Twelve years? Curiously long life for a common garden rat!He's missing a toe, isn't he?
Ron: So what?
Harry: All they could find of Pettigrew was his……
Sirius: Finger!Dirty coward cut it off so everyone would think he was dead!And then he transformed into a rat!
Harry: Snow me. Give it to him, Ron.
Ron: What are you trying to do to him? Scabbers!Leave him alone!Get off him!What sre you doing?
Pettigrew: Remus? Sirius. My old friends!Harry!Look at you. You look so much like your father. James. We were the best of friends.
Sirius: How dare you speak to Harry!How dare you talk about James in front of him.
Lupin: You sold James and Lily to Voldemort!
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: Died, rather than betray my friends!

Pettigrew: Harry, James wouldn't have wanted me killed!Your dad would have spared me! He would have shown me mercy!
Sirius: Should have realized if Voldemort didn't kill you, we would. Together!
Harry: No!
Lupin: Harry, this man……
Harry: I know what he is. But we'll take him to the castle.
Pettigrew: Bless you, boy. Bless you!
Harry: Get off!I said we'd take you to the castle. After that, the dementors can have you.

Sirius: It's beautiful, isn't it? I'll never forget the first time I walked through those doors. It'll be nice to do it again as a free man. That was a noble thing you did back there. He dosen't deserve it.
Harry: I didn't think my dad would have wanted his best friends to become killers. Besides, dead, the truth dies with him. Alive, you're free.
Sirius: I don't know if you know, Harry, but when you were born, James and Lily made me your godfather.
Harry: I know.
Sirius: I can understand if you choose to stay with your aunt and uncle, but if you ever wanted a different home……
Harry: What? Come and live with you.
Sirius: It's just a thought. I can understand if you don't want to.
