[Harry and Hermione enter the Shrieking Shack and find Ron in a room]
Harry:
Ron!
Hermione:
Ron, you're okay!
Harry:
The dog. Where is it?!
Ron:
Harry, it's a trap! [points to Sirius standing behind the door] He's the dog! He's an Animagus!
[Harry and Hermione look down on the floor and follow the paw prints to where Sirius is standing]
Hermione:
[protecting Harry behind her] If you want to kill Harry, you'll have to kill us too!
Sirius:
No. Only one will die tonight.
Harry:
Then it'll be you! [angrily rushes over to Sirius, holds him down, and threateningly points his wand at him]
Sirius:
[chuckles] Are you going to kill me, Harry?
Lupin:
[enters the room and disarms Harry's wand] Expelliarmus! [orders Harry to step aside] 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, Remus? [Lupin smiles, helps him get back up on his feet, and they hug] 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 really 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 but it was 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!
