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.

Professor Minerva McGonagall: Years ago, when Potter's parent's were marked for death, do you remember? They went into hiding. Few knew where they were. One who did was Sirius Black. And he told You-Know-Who!
Cornelius Fudge: Not only did Black lead You-Know-Who to the Potters that night, he also killed one of their friends, Peter Pettigrew.

Madame Rosmerta: Peter Pettigrew?
Professor Minerva McGonagall: Little lump of a boy, always following after Sirius Black.
Madame Rosmerta: Oh, I remember him. Never let James and Sirius out of his sight. But what happened?
Professor Minerva McGonagall: Well Peter Pettigrew tried to warn the Potters, and might

have managed to if he hadn't run into an old friend.
Madame Rosmerta: Mhm, Sirius Black.
Cornelius Fudge: Black was vicious. He didn't kill Pettigrew, he destroyed him. A finger. That's all that was left, a finger. Nothing else.
Professor Minerva McGonagall: Sirius Black may not have put his hands to the Potters, but he's the

reason they're dead.
Cornelius Fudge: And now he wants to finish what he started.

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.
