As I'm feeling generous have another chapter :)

Snape tossed away the cloak. "I found this at the base of the Whomping Willow." His eyes were glinting with silent victory. "You're wondering perhaps how I knew you were here? I stopped by your office tonight Lupin. You hadn't taken your potion so I kindly took a gobletfull along. And then I saw a map on your desk. Very interesting, it showed you running along a tunnel and I decided to follow. I knew you'd been helping your old friend get into the school and now here's the proof."

Lupin stepped forward holding up his hands. "Severus. You're making a mistake. Sirius is not here to kill Harry…"

"Two for Azkaban tonight." Snape hissed and then looked down at Hazel. "Well two and a half." He sneered. "I'm sure Dumbledore will be very interested to know what you've been up to Lupin. He thought you were safe. A tame werewolf."

"You fool." Lupin shook his head. "You're going to let a schoolboy grudge send an innocent man to Azkaban."

BANG. Thin black cords shot out of Snape's wand and wrapped around Lupin sending him falling to the ground. Sirius sprang forward but Snape turned his wand onto him, holding it right between Sirius's eyes. "Give me a reason. I dare you." Snape snarled.

But before either man could do anything but glare at each other with pure hatred Hazel slowly stood up and put herself in between Snape and Sirius. And then she smiled at the potion's master.

Snape glared at the girl. "Young lady I would suggest you mo…"

Harry watched as Snape's wand hand dropped to his side like it was a lead weight. Snape looked at Hazel with wide eyes as he turned like a marching soldier and sat down on the bed. Hazel walked over to stand in front of him and placed her hand on his head and mumbled something and Snape fell backwards, unconscious.

"What did you do?" Harry exclaimed.

Hazel looked at him with a grin. "He's fine. Just asleep." She looked around. "Perhaps we should move this along. It looks like Ron is having trouble keeping hold of Pettigrew."

Sirius nodded. "It's time we showed you. Boy give me Peter."

Ron shook his head. "Oh come off it. Are you seriously trying to tell us that you broke out of Azkaban to come after Scabbers? Even if Scabbers were Pettigrew, how could you know it was him?"

Lupin finished freeing himself from Snape's ropes and stood up. "He does have a point Sirius, how did you know?"

Sirius reached into his robes and pulled put the cutting from the Daily Prophet. "Fudge gave me this when he came to inspect the prison. I instantly recognised Peter. I mean how many times had I seen him transform? And the article said that the boy went to Hogwarts. Where Harry was."

Lupin nodded. "My God…" He looked between the picture and Scabbers. "His front paw…"

"What about it?" Ron asked.

"He's missing a toe." Lupin looked at Ron. "Didn't you hear Ron, the biggest part of Peter they could find was his finger."

Sirius nodded. "I had the coward cornered. He yelled for everyone to hear how I'd betrayed Lily and James and then he blasted the street with his wand behind his back, cut off his finger and transformed."

Ron scoffed. "Look there are a million reasons why Scabbers could be missing a toe. He probably got in a fight with another rat. He's been in my family for years."

"For twelves year to be exact. Don't you think that's a very long time for a common rat?" Hazel asked him.

"We've been taking good care of him." Ron answered weakly.

"He doesn't look very well now." Lupin commented. "I bet he's been getting sicker since he found out that Sirius escaped."

Ron shook his head. "He's been terroised by that mad cat." He pointed at Crookshanks who had once again curled up in Hazel's lap.

Hazel frowned. "This cat isn't mad. He's the most clever little pud pud there is." She scratched at Crookshanks ears.

Sirius nodded. "He's been helping us all year. He knew straight away what Peter was and what I was when he ran into me. It took a bit of time but I was able to communicate what I needed to him. He tried to bring the rat to me but when that failed he stole the passwords to Gryffindor Tower from a boys bedside table. But it seemed Peter got wind of what was going on because he once again tried to fake him own death. I guess he bit himself to leave blood on the sheets and make it seem like this cat had eaten him."

"And why would he feel the need to do that?" Harry snapped. "Because you're coming to finish the job. To kill him."

"Yes." Sirius said darkly.

"Then maybe I should wake Snape up and let him take you." Harry snarled.

Lupin shook his head. "No Harry. All this time we thought Sirius betrayed your parents and Peter tracked him down but it was the other way around. Peter betrayed your parents and Sirius tracked him down."

"THAT'S NOT TRUE! HE SAID BEFORE YOU GOT HERE. HE SAID HE WAS THEIR SECRET KEEPER AND HE KILLED THEM!" Harry shouted.

"Harry…" Sirius croaked. "I as good as killed them. I was supposed to be their Secret Keeper but I convinced Lily and James to switch last minute. I thought no one would suspect that pathetic, whimpering Peter would be their Secret Keeper and they'd come after me, the obvious choice." He sighed. "I'm to blame. I know that. I had arranged to check on Peter the night they died. When I saw his hiding place empty with no sign of a struggle I knew something was wrong and rushed to your parent's house. When I found the house in ruins and saw their bodies… I realised what Peter had done. What I'd done." He shook his head. "I was about to leave to find him when I heard Hazel crying in the rubble. I found her and took her to my old home, where I left her in the care of a House Elf called Kreacher and went straight out to track down Peter." Sirius explained.

"Enough of this." Lupin said. "There is one way to prove that Sirius is telling the truth. Ron give me that rat." He demanded.

Ron frowned. "What are you going to do to him if I give him to you?"

"Force him to show himself. If he is just a normal rat, it won't hurt him." Lupin said softly.

Ron looked hesitant before finally handing over Scabbers to Lupin. The rats eyes buldged from his head as he started squealing even more as Lupin held onto him.

"Ready Sirius?" Lupin asked.

Sirius got to his feet drawing his wand and nodded stiffly. "Together?" He said quietly.

"I think so." Lupin agreed.

Hazel got to her feet and drew her wand. Her eyes fixed on the rat.

Remus and Sirius both pointed their wands at the rat and suddenly there was a flash of white light and in it's place stood a short balding man with watering eyes which kept darting to the door and windows. "S-Sirius? R-R-Remus. My fr-friends. My old friends."

"Hello Peter. Long time no see." Lupin said pleasantly like it was a regular thing for rats to turn into old school friends. He reached out and grabbed Sirius's wand arm lowering it. "We've been having a little chat Peter. About what happened the night Lily and James died. You might have missed a few things with all the squeaking you were doing on the bed."

"You don't believe him do you Remus? He tried to kill me Remus." Peter cried out.

Lupin nodded. "So I've been told."

Peter whimpered. "He's going to try to kill me again!" He cried. "He killed Lily and James and now he's come to kill me. You have to help me Remus."

"No one is killing anyone until we've sorted a few things out." Remus said calmly.

"Sorted things out? I knew he'd come for me. I've been waiting for this day for twelve years." Peter babbled pointing a finger at Sirius.

Remus frowned. "You knew Sirius was going to break out of Azkaban when no one has done so before?" He asked.

Peter was sweating heavily now. "He-Who-Must-Not-Be-Named must have taught him some tricks. I bet he has dark powers we can only dream of." He backed away slightly, eyes still darting to the door and windows.

Sirius let out a bark like laugh. "Voldemort? Teach me tricks?" He sneered watching Peter visibly flinch at Voldemort's name. "What's the matter Peter scared to hear your old master's name? I don't blame you. His lot aren't very happy with you are they?" He asked darkly taking a step forward.

Peter stumbled back. "Don't know what you're talking about."

"You haven't been hiding from me for the last twelve years Peter. I heard quite a few things in Azkaban. Lot of Voldemort's big supporters in the same place as I was and they're not happy with you. They think the double crosser, double crossed them. After all who gave Lord Voledmort the information that led to his downfall. And not all of his followers went to Azkaban did they. Now they think you're dead but imagine what would happen to you if they found out you were alive."

Peter kept shaking his head mumbling things like 'ludicrous' and 'preposterous.' "If Lord Voldemort's followers are after me it's because I helped put away the spy Sirius Black."

Sirius growled. "How dare you?" He snarled. "Me? Voldemort's spy? When did I ever sneak around people more powerful than me? I should have known it was you from the start, I don't know why I didn't see it. After all you used to like big friends who could take care of you. It used to be me and Remus and… and James. I thought it was the perfect bluff. No one would expect pathetic weak Peter was the Potter's Secret Keeper. I was sure that Voldemort would come after me. It must have been the best day of your life when you told him you could hand him the Potters."

"Mad. You're completely mad." Peter mumbled. "Remus you can't believe him?"

"I'm struggling to understand why an innocent man would spend twelve years hiding as a rat?" Lupin questioned.

Peter spluttered. "Innocent but scared." He exclaimed.

Hermione slowly raised her hand like she was in class. "Er Professor Lupin may I ask a question?" She asked timidly.

Lupin nodded. "Of course."

"Well - Scabbers… I mean this man. He's been sleeping in Harry's dorm for three years and if he was working for Vol-Voldemort why hasn't he tried to hurt Harry?" Hermione asked.

"Yes. Thank you. You see Remus? I've never hurt a hair on Harry's head. Why would I?" Peter gasped.

"I'll tell you why." Hazel snarled taking a step forward. "Because you'd want to make sure Voldemort is at the top of the foodchain again. What use is it doing something that would risk your neck when your nice and safe and cozy. You've been biding your time, keeping your ear to the ground. I'm guessing that's why you picked a wizarding family."

Peter looked between Hazel and Remus. "You can't possibly believe this girl that Sirius has… has brainwashed against me."

"Excuse me. Mr Black… Sirius?" Hermione asked.

Sirius jumped his eyes wide obviously not used to being addressed so politely.

Hermione glanced around. "If you don't mind me asking… How did you break out of Azkaban if you didn't use Dark Magic?"

Sirius rubbed the back of his neck. "If I'm honest… I'm not sure how I did it."

Hazel sat back down on the bed, her head pounding and closed her eyes. She could feel herself floating away but she tried to swim back to the ground. But it was like a strong current in the ocean pulling her under and then she was gone.

"Believe me." Sirius pleaded with Harry. "Please, believe me. I would never betray Lily and James." His voice croaked.

Hazel opened her eyes and saw Harry nod his head before she was pulled under again.

"No." Peter wailed falling to his knees. "Sirius please… Remus, you wouldn't let him kill me?" He turned and crawled over to Ron. "Ron… You won't let them kill me? I was good pet wasn't I?" He reached for Ron.

Ron recoiled, a look of disgust on his face. "I let you sleep in my bed."

Peter turned to Harry. "Harry please. James wouldn't have wanted me killed. You know you look just like him. Like James."

"How dare you speak to Harry about James!" Sirius barked pulling Peter away from Harry and into a corner. "You sold Lily and James to Voldemort, do you deny it?"

Peter snivelled. "I didn't mean to. I wasn't brave like you, Remus or James. The Dark Lord… He has weapons you can't even dream of. I was forced…"

"DO NOT LIE!" Sirius bellowed. "YOU HAD BEEN PASSING ON INFORMATION TO VOLDEMORT FOR A YEAR BEFORE LILY AND JAMES WERE KILLED!"

"He was taking over everything. What was there to be gained from refusing him?" Peter argued covering his face with his hands.

Sirius frowned. "What was to be gained from fighting the most evil wizard of the century? Only innocent lives Peter." He exclaimed fury etched on his face.

"He would have killed me." Peter wailed.

"THEN YOU SHOULD HAVE DIED!" Sirius roared over Peter's cries. "DIED FOR YOUR FRIENDS! AS WE WOULD HAVE DONE FOR YOU!"

Remus and Sirius stood side by side their wands raised at Peter. "You should have realised Peter, that if Voldemort didn't kill you then we would. Goodbye Peter." Remus said softly.

"NO!" Harry yelled running forward to put himself between Peter and the wands. "You can't kill him. You can't."

"Harry this piece of filth is the reason you don't have parents. He would have seen you die just to save his own worthless skin. He doesn't deserve your mercy." Sirius shook his head.

Harry nodded. "I know but we'll take him up to the castle. Hand him over to the Dementors, he can go to Azkaban. Just… don't kill him." He pleaded.

Peter crawled over to Harry, grabbing at his robes. "Thank you. Thank you Harry… It's more than I deserve." He babbled.

Harry pulled away from him. "Get off me. I'm not doing this for you. My dad wouldn't have wanted his best friends to have become killers because of you."

There was complete silence as Harry's words sunk into the group.

"It's your decision Harry." Sirius said softly. "But think… Think about what he did?"

"He can go to Azkaban. If anyone deserves that place he does." Harry caught sight of Hazel unconscious on the bed. "Is she okay?"

Sirius turned around. "Not again Hazel." He hurried over to her, kneeling down beside the bed. "Hazel." He gently shook her shoulder. "Come on kid, come back to me."

Hazel gasped and opened her eyes grabbing the front of Sirius's robes. "Fire. Everything was on fire."

"Hazel, it's okay." Sirius gripped her shoulders. "It's okay."

Hazel looked at Sirius with tears in her eyes. "It was horrible." She whispered. "People… In the sky… Screaming… I can still hear the screaming."

Sirius pulled her in for a hug. "It's okay. You're safe."

Harry frowned taking a step closer. "Are you okay?" He asked Hazel concerned.

Hazel looked up at him through teary eyes. "Yeah." She wiped her eyes on her sleeve. "I'm okay." She sniffed. "Bad dream."

"How can you dream through all this?" Ron asked in confusion.

"It kind of just… happens." Hazel shrugged. "Since I was a little kid." She stood up and looked down at Peter. "What are we doing with him?" She sneered.

Harry looked at her. "Taking him up to the castle and handing him over to the Dementors."

Hazel stared at Harry for a long moment before slowly nodding her head with a sigh. "If that's what you want to do."

"Really?" Harry frowned. "I thought you'd be more for killing him?"

"Well yeah but whether you believe me or not you're my brother and I trust you." Hazel gave him a small smile.

Harry looked at Hazel properly. It really was like looking in a mirror at a female version of himself. Except for her eyes, her eyes were hazel instead of green. "You're really my sister, aren't you?"

Hazel nodded.

Lupin nodded. "Very well, stand aside Harry, Hazel."

Harry frowned. "What…"

"I'm just going to tie him up." Lupin explained.

"But if he transforms we kill him. Do you agree Harry, Hazel?" Sirius asked the siblings.

Both siblings nodded.

Lupin turned to Ron. "Now Ron, I cannot mend bones as well as Madam Pomfrey so I think it would be better if we just strapped up your leg until we get to the castle." He muttered a spell and a splint strapped up Ron's leg.

"I can help." Hazel stepped forward. "I'm not a healer but I have developed a little trick. It'll help with the pain." She explained.

Ron nodded. "Sure, I'll try anything."

Hazel walked over and placed her hand on his arm and focused, feeling his pain and drawing it away like she was drawing poison from a snakebite.

Ron gasped when she took her hand away. "Help with the pain? If I didn't know I'd broken my leg, I could probably dance a jig." He joked. "How did you do that?"

Hazel shrugged. "Just a trick I picked up." She answered.

"Neat trick." Ron nodded and went to stand up only to fall to the floor, his leg giving out underneath him.

"Yeah. I took your pain away but you're leg is still broken." Hazel helped him back onto the bed. "So how do we do this?"

"Hermione and I can help Ron." Harry offered.

"I'll bring Snape." Sirius glared at the unconscious man.

"Which leaves me to the rat." Hazel glared at a now bound Pettigrew who wimpered. "Mr Lupin, I do believe if I've kept up to date with the calander today is a full moon. Perhaps it would be best if you remained behind." She smiled kindly at Remus.

Professor Lupin. "You're right Hazel. In fact I would suggest you all move quickly as it shall not be long before I transform and I have not taken my potion this evening."

And with that said the group began their descent back through the tunnels and to Hogwarts. Crookshanks leading the way. Sirius levitating Snape in front of him. Hazel behind him somehow making Pettigrew walk in a stiff motion. Harry, Ron and Hermione bringing up the rear.

Find out what happens next soon. Hope you enjoyed this chapter :)
