'blah' means thoughts

Chapter Four – Prisoner of Azkaban Part Two

"Tell me about Peter Pettigrew," Harry demanded, interrupting the moment. He had his wand out, pointing at Remus.

"He was at school with us. We thought he was our friend," Remus answered.

"No. Pettigrew's dead. You killed him!" Harry pointed his wand at Sirius.

Remus stepped between the wand and Sirius. "No, he didn't. I thought so too until you mentioned seeing Pettigrew on the map."

"The map was lying then," Harry declared.

"The map never lies!" Severus hissed.

"Right. Pettigrew's alive, and he's right there!" Sirius pointed in Ron's direction.

"Me? He's mental!"

"Not you! Your rat!"

"Scabbers has been in my family for-"

"Twelve years. A curiously long life for a common garden rat. He's missing a toe, isn't he?" Sirius cut in.

"So what?" Ron asked, defensively.

Harry lowered his wand. "All they could find of Pettigrew was his-"

"Finger," Sirius cut in. "Dirty coward cut it off so everyone would think he was dead, and then he transformed into a rat.

"Show me," Harry said. Sirius grabbed at Scabbers, who Ron moved out of the way. "Give him to him, Ron."

"What are you trying to do to him?" Ron cried as Sirius grabbed Scabbers none too gently. "Scabbers! Leave him alone! Get off him! What are you doing?"
Remus and Sirius started flinging spells at the escaping rat, one of which actually made contact. The rat transformed into Peter Pettigrew. Severus's eyes widened at the sight of his supposedly dead friend. After getting over his shock, Severus's first thought was, 'Twelve years as a rat has not been kind to Peter.'

"Remus? Sirius? Severus? My old friends." Peter tried to run out of the room, but his way was blocked by Harry. "Harry, look at you. You look so much like you father, like James. We were the best of friends-"

Sirius grabbed Peter, pulled him off Harry (much to Harry's relief), and pushed him in the opposite direction of the door. "How dare you speak to Harry? How dare you talk about James in front of him?"

"You sold James and Lily to Voldemort, didn't you?" Remus had his wand pointed at Peter.

"I didn't mean to. The Dark Lord. You have no idea the weapons he possesses. I thought of Sirius. What would you have done? What would you have done?"

'Peter actually handed James and Lily over You-Know-Who. Amazing,' Severus thought.

"I would have died! I would have died rather than betray my friends!"

Sirius's outburst scared Peter so much it sent him scurrying under the busted piano and toward Harry. "Harry, James wouldn't have wanted me killed. Your dad, your dad would've spared me. He would've shown me mercy."

Severus and Remus grabbed Peter and pulled him off Harry. Severus, Remus, and Sirius all pointed their wands (well, Sirius was holding Harry's wand) at the cowering Peter as Severus exclaimed, "You should've realized, Peter, that if…Voldemort didn't kill you, then we would together!"

"No!" Harry called out.

Remus sighed. "Harry, this man-"

"I know what he is, but we'll take him to the castle," Harry cut Remus off.

Peter dropped to his knees. "Bless you, boy. Bless you."

Harry kicked at Peter. "Get off. I said we'll take you to the castle. After that, the Dementors can have you."

Severus had to smirk. 'The boy surely knows what the consequences of those actions are, and maybe, just maybe, things will change.'

"So, Snivellus, are you leaving before us?" Sirius asked.

'Then again, maybe not.' "I still don't trust you, Black, so you leave first."

Sirius looked like he was about to retort, but Remus cut in with, "Why don't you and Harry help Ron up the stairs, Sirius? Hermione will follow you three, and I'll make sure Peter doesn't get away. Severus, you can come up when you're ready."

That seemed to satisfy everyone. Sirius gave Harry his wand back, and Harry returned Hermione's wand. Then, Harry and Sirius helped Ron to his feet and up the stairs like Remus had suggested. Hermione followed Sirius, Ron, and Harry, and Remus made Peter follow (at wand point). Severus, however, made no move to follow the group. His thoughts were running wild.

'Hmm. So, Black never killed anyone, but that doesn't mean that he's not capable of it. I never would have believed that Peter could have had a hand in Lily's and James's deaths. I would never have believed that Peter was actually alive, even though Remus mentioned seeing him on the map. I guess he was trying to see Peter one more time when I came by…Merlin's Beard! Remus didn't take the last dose of the Wolfsbane potion!'

Severus broke into a run, however; he only got as far as the blood stained hallway before the transformation started. He tried to get a little further, but the changing prevented him from moving. Once the transformation was complete, however; Severus started running again. When he got to the bottom of the stairs, he heard a familiar sound – the distinct howl of a nearby werewolf. The howl spurred him to climb the stairs with immense speed. He leapt through the opening, landing in front of the three Gryffindor students in a traditional defense stance.

Remus roared at the strange werewolf and swiped at the group. Fortunately, he only left a scratch on Severus's side. At that point, a large black dog tackled Remus from the side. Severus recognized the dog as his nemesis, Sirius Black. Black struck a defensive posture in front of Severus and the students. Severus risked a glance back at the trio to make sure none of them were injured. He caught Hermione's eye, and she realized the werewolf in front of them was actually their Potions professor. She recognized the look of concern in his eyes as well as a glimpse of humanity.

Suddenly, Remus charged at Sirius, who followed suit. The ensuing dog fight was vicious with teeth flashing, jaws snapping, and paws flying. Remus managed to toss Sirius a few feet away and advance towards Severus, who was ready to defend the students. Out of nowhere, Sirius came up and bit Remus's left front leg, which caused the werewolf to chase him.

"Sirius!" Harry yelled as he began to chase the two canines. Hermione made a move as if she was going to follow Harry, but Severus turned his head and growled at her, which froze her in her tracks.

Severus motioned with his head at the students and then towards the castle. Hermione nodded and helped Ron follow Severus. He led them to the courtyard in front of the castle. Once there, Hermione took Ron inside.

Satisfied that the two students were taken care of, Severus took off to find Remus. There was only one chance he had to stop a rampaging Remus, and it might not even work! 'Since Remus is the one who delivered my bite, it's possible he may recognize me as kin. All I have to do is show him my left front leg.'

It took Severus half the night to find Remus, but he finally found him in the Forbidden Forest, nursing a few recent scratches. The second his scent reached Remus's nose Severus noticed that Remus went on the alert. Severus displayed a non-threatening attitude towards Remus, which caught Remus's attention. Remus relaxed slightly, but was unsure of Severus's intentions.

Severus slowly lifted his left front leg in Remus's direction. Remus inched forward and lowered his head to sniff the patch of light grey fur in front of him. The scent was the werewolf's mixed with his won. The scent screamed kin.

Severus motioned with his head for Remus to follow him, which he did. Severus was relieved that his plan worked. 'Now, keeping an eye on Remus should be easy.' Severus led his best friend to the Shrieking Shack. Remus slunk over to the opposite corner and lay down. Severus lay on his side with his hind legs against the floor in a relaxed position and his upper body positioned like the Sphinx of Egypt. Severus watched over Remus until dawn.

%%% THE NEXT AFTERNOON

Severus was walking towards Remus's office to see how he was fairing after last night's ordeal. They had found out that Peter was alive and that Black didn't have a hand in the murder of James and Lily. Severus was so lost in these revelations that he walked by Harry without so much as a passing glance. He just kept walking towards Remus's office.

However, he saw Remus walking towards the front doors. Severus caught up to his best friend. "Remus, what happened?"

Remus smiled sadly. "I resigned, Sev. It seems someone let slip the nature of my illness."

"It was probably Draco Malfoy. Smart little sod has a knack for catching wind of things that he's not supposed to know. Do you want me to question him?"

"It won't make a difference. The owls will still come."

"Oh."

A short pause passed before Remus changed topics. "I gave the map back to Harry."

"What? Why?"

"I think James would've wanted Harry to have it, and besides, I'm not his professor anymore, so why would I care whether he has the map or not?"

"Moony!"

Remus chuckled. "Relax, Shadowfang. Harry's got more common sense than James had." Remus smiled slightly. "Seriously, Sev. I'll miss you."

Severus wrapped his arms around his best friend. "And I'll miss you, Remus."

They broke the hug, and Severus watched his best friend walk out of the castle and out of his (daily) life forever.

THE END
