Harry looked in shocked terror at the man he had come to trust; never would he have thought Professor Lupin would be the traitor. To knowingly associate with Black after what he'd done to his parents...how could he? To his side Hermione started screaming at Lupin and then she revealed him to be a werewolf causing Harry to wince. They'd known for a long time that Lupin was a werewolf, but unless something dire happened they'd sworn to never mention it. Instead of looking angry though, Lupin looked completely and utterly disgusted with himself.
"How long have you known?" Lupin muttered and before anyone could answer Sirius cut in.
"Don't worry about them Remi, I've found him, let's kill him!" Sirius grinned and Remus nodded looking at Harry.
"First I have to make sure that Harry understands what's going on. He's suffered enough and he needs to understand what's actually going on." Remus insisted but instead of Sirius agreeing another voice filled the room.
"Black! I thought I'd find you here. Are you all ok?" Severus inquired looking at the group of teenagers huddled together in the corner.
"He hurt Neville." Hermione explained pointing to Neville who was bleeding from a wound in his leg.
"What about the rest of you?" Severus probed keeping his wand trained on Black.
"We'll be ok." Hermione assured and Severus nodded moving closer to the children only to feel someone shove him from behind causing him to fall. As his body hit the ground Severus felt pain shoot through his left wrist and almost smashed into the ground. He looked up and realized the children's eyes were wide. When he glanced back he felt his own eyes widen; standing behind him was Peter Pettigrew.
"Pettigrew?" Severus murmured and Sirius started chuckling.
"Very observent, Snivellus." Sirius sneered and Harry felt his blood boil.
He reached into Hermione's pocket and slid her wand out. He pointed it dead at Black and fired. At first it looked like the curse was going to send him flying backwards, but at the last minute a shield sprang in front of Sirius.
"Nice try, Potter, but you'll have to be faster than that." Pettigrew sneered and Severus started to crawl forward towards the kids.
"Crawling like a worm, Snivelly?" Pettigrew chuckled and made to move toward him only to feel a stinging hex catch him in the face. As he turned back, Severus was standing defensively between Potter and the Granger girl while Potter had a different wand in his hand and was glaring at him.
"Sirius, what are you doing? Make him stop." Remus demanded and Sirius turned toward him shaking his head no.
"I can't do that, Remus. You see I thought I could get you to listen when I got Peter to appear on the map. I thought Harry would be friends with the Weasley boy, so I was going to make Peter kill Scabbers and trade places. This would have given the illusion that Peter was the one I've been after this entire time. You can imagine my surprise when Weasley wasn't even close to being Harry's friend, but instead someone who barely even acknowledges that he exists. I always thought that Harry would be a James mini; Gryffindor, popular, into Quidditch, and very, very foolish to trust so easily. I guess that horcrux behind your scar though changed your personality more than I thought it could." Sirius smirked and looked in amusement as Harry hesitantly touched his scar.
"Horcrux? Behind my...what?" Harry questioned with a trembling voice, but when Sirius looked up Harry was laughing and the scar was completely gone.
"What?" Sirius boomed.
"Did you hear that?" Minerva demanded and Filius nodded back in agreement. "Everyone have their wands at the ready?" Albus questioned and at the nods of the others he motioned them all forward.
"And now, the famous Boy-Who-Lived is protecting the slimy git that we tortured as children." Sirius laughed and Remus felt his eyes hardened.
"That shows how much James really didn't trust you. His only mistake was that he trusted the little rat here. He made you secret keeper at the beginning to see how fast you would tell the others and then when you didn't he switched to Peter. We all knew it was one of you, possibly both, and so we refused to tell anyone what was really going on. After you almost got me to kill Severus, James suddenly found himself disliking you and feeling guilty for everything he'd said to Severus. There were traces of a potion in James's blood that was making him overly hostile towards Severus. Once the potion was gone James and Severus mended bridges, but kept up appearances around you. No one, not even Pettigrew, was connected enough to get a potion that was that potent. Not anyone that is except the heir to the House of Black. You were removed long ago as Harry's Godfather and he was given one that both Lily and James trusted. So if you even think of hurting my nephew...I'll murder you, Black." Remus snarled and stepped backwards toward the children to stand just in front of Harry.
"I guess I'll have to kill you first then." Sirius smirked and raised his wand when he was stunned from behind. A spell shot towards Pettigrew and he dodged yanking out his necklace and grabbing Sirius's wrist as they were both yanked away.
