Sorry it's been so long, but i'm moving and it's a pain in the ass. Plus writer's block, and it's been slow. But it's here! :)

"If my hunch is correct," said Dumbledore carefully. "And they usually are, he is the man responsible for your parents' deaths."

"W-What?" said Harry in disbelief. "I thought Lord Voldemort was killed my parents!"

"He did," said Lupin. "But only because your parents were betrayed. Up until today, until ten minutes ago, I-everyone-believed it was Sirius. Sirius Black. He was your parents' Secret-Keeper."

"Except he wasn't, was he?" said Dumbledore, and although his voice was calm it sent shivers down Harry's spine. "You were, weren't you, Peter?"

The small, balding man whose name was Peter made a choking noise. "I-I wasn't, I swear," he managed finally. "This is all a big misunderstanding, I would never, Remus, you know I wouldn't..."

He reached out to Lupin, who recoiled and pointed his wand even more firmly at Peter.

"I don't know, Peter," said Lupin. "Why would an innocent man spend eleven years as a rat?"

At this, Ron let out a low moan. Harry glanced at him to see his best friend staring at the man who used to be Scabbers in horror. "I let you sleep on my bed..." he whispered.

"You were kind," squeaked Peter, turning to Ron pleadingly. "You were kind for taking me in, your and your brothers, so kind, so kind..."

Ron stepped away from Peter so quickly he tripped back onto his bed. Peter turned to Harry, who recoiled.

"Sweet boy...you have your mother's eyes...I would never betray her, never..."

"Don't talk to him," hissed Lupin. Harry got the impression that if Dumbledore and McGonagall weren't in the room he would have just hexed Peter.

"I don't understand," said Harry. "Did Sca-did he ransack my room?"

"No!" cried Peter frantically. "No, no, I didn't, I swear. I didn't even see who did it, I was asleep, I swear..."

More than anything he'd said so far, this rang true.

"So...what's a Secret-Keeper?" ventured Harry.

"I will explain it to you later," replied Lupin. "Taking care of Pettigrew is more important."

"Now what, Professor?" asked McGonagall, turning to Dumbledore for guidance. "What do we do now?"

"Minerva, send an owl to the Ministry at once. Tell them to bring Aurors as soon as possible, and request that no dementors be brought."

McGonagall nodded and left the room.

"Professor," said Lupin, his voice suddenly strange and thick again. "Do you think this means...that after all these years...Sirius..."

"Sirius is, in all probability, innocent," said Dumbledore calmly.

This meant little to Harry. Professor Lupin, however, looked as though he wanted nothing more than to collapse onto Harry's bed. Ron gasped.

"S-Sirius...Sirius Black? The mass murderer?"

Peter whimpered. "Sirius isn't innocent, I've been hiding from him, in case he escaped..."

"Escaped from Azkaban, something no one else has ever managed?" said Dumbledore, and there was no mercy in that voice. "I find that difficult to believe."

Peter's round face crumpled. "I did not mean to...they were my friends, I loved James and Lily, I did..."

"You sold them out to Voldemort," said Dumbledore sharply. "There was no love in that."

Peter collapsed into tears, and Lupin, trusting Dumbledore to handle it, sat heavily onto Dean's bed.

"What does this mean?" said Harry quietly. "For...for me?"

Professor Lupin managed a weak smile. "It means...if all goes well, Sirius Black will be acquitted for the murders he was convicted of. He will be freed, and..."

"And?" prompted Harry.

"If all goes well, and he is still the same person after these eleven years, he may take you to live with him."

"L-Live with him?"

"Only if you want to. You see...Sirius is your godfather."

And suddenly, despite standing in the presence of the man who ohad betrayed his parents to Voledmort, Harry felt a sudden warmth spread in his chest and suppressed the strong urge to smile.
