The reveal scene from Prisoner of Azkaban

♡---Intro message---♡

a loud crash comes from the upper floors of the shrieking shack, Snape had been blasted away by Harry in seeming defense of Sirius, "Harry! what did you just do?" Ron cries out holding Scabbers in his arm, "You just attacked a teacher!" Hermonie says a bit flabbergasted, her mouth hanging open.

Harry then turns his wand onto Sirius speaking in a serious tone, "Tell me about Peter Pettigrew." Remus quickly cuts in standing in front of Sirius, "He was at school with us, we thought he was our friend." This awnser doesn't sit right with Harry as his grip tightens on the wand he stole from Hermione.

"No, Pettigrew is dead" his wand flicking once more onto Sirius, "You killed him." Sirus looks a bit hurt at the accusation, knowing that it was Peter who sold out the Potters not him, "No he didn't! I thought so too, until you mentioned seeing Pettigrew on the map." Remus butt's in offering defense for his friend, Harry counters with, "Then the map was lying" Sirius shakes his head, "The map never lies, Pettigrew is alive, and he's right there" He points to Ron's arms

"ME? that's mental!" The Ginger calling out the absurdity of his claim, to which Sirius groans and shakes his head in mild frustration, "Not you. Your rat!" Ron looks confused, "But this rat has been in my family for-" Sirus cuts him off with a guess "12 years?"

Sirius slowly takes steps toward Ron, "Curiously long life for a common garden rat! He's missing a toe isn't he?!" He accuses pointing at the Scabbers once more, "So what?" The Weasley questions, Harry however is putting the dots together in his head, lowering his wand a bit, "All they could find of Pettigrew was.."

Once again the man takes the opportunity to spell it out, "His finger! the dirty coward cut it off so that everyone would think he was dead!" He then turns to the rat in Ron's arms glaring at it, "And then he transformed into a rat."

"Show me." Harry demands, much to Sirius delight as he goes to grab Scabbers out of Ron's hands "Give it to him Ron" Harry was curious to see how Sirus would prove this rat was indeed Pettigrew.

Sirius finally gets a hold of Scabbers, much to Ron's despair, "What are you trying to do to him!?" He protests, "Scabbers! Leave him alone!" Hermonie holds Ron back a bit curious herself "Get off of him, what are you doing?" The rat scampers across the piano as magic is blasted at it by Sirius.

Each shot missing, until the rat reaches a hole to the outside of the bedroom everyone was in, the spell finally hitting its intended target, Causing Pettigrew Pettigrew to be revealed, taken out of his animigus form

As he is pulled out of the hole by Remus and Sirius, the trio looked stunned, as Peter tears himself out of the pairs hands running to Harry, pleading, "Your parents wouldn't have wanted this!"

Peter Pettigrew was grabbed by the shoulders and was thrown off Harry Potter by Sirius Black and Remus Lupin they point their wands at him having Pettigrew cornered.

"You should had realized Peter, that if Voldemort didn't kill you we would! together" Sirius spits while he and Remus stand over Pettigrew

they were about to attack but before Harry could yell "no" they heard a sound, Ron and Hermione look where Snape was, he was still knocked out
