Disclaimer : This is just a shorter Fanfic to keep you guys entertained while I write my longer Marauders Fanfic. Also, this Fanfic is about the incident mostly known as, "the prank", if you are unfamiliar with it you can find some information about it on the Harry Potter Marauders Wiki. Also I know that Peter was one of the Marauders but I don't think he had much to do with this incident. I hope you enjoy my short fanfic! :)

SSSSS

It was Sirius's sixth year in Hogwarts, and all was very well. Him and his dorm mates had terrorized the Slytherin's once again, his best friend James was finally getting with Lily, and probably the best thing of all, Sirius, James, and Peter had become Animagi to help their friend Remus with his monthly transformations. It seemed that everything was the way it should be…

"James! Could you pass me the butter?" Sirius said, gesturing towards the stick of butter that was sitting in front of his best friend.

James passed him the butter, "You could clearly reach it from where you're sitting at the table you know!" James laughed, nudging him a bit.

Suddenly, a girl walked over to their table. Her long, reddish brown hair flew in the wind, and the way she walked could summon every single boy who went to Hogwarts.

"Hi Lily," Remus nodded to the girl and she nodded back, smiling.

"Hello," Peter squeaked and Lily nodded towards him as well. Then, her gaze landed on James. He bit his lip, clearly a bit uncomfortable.

"Hi James…" Lily said a bit awkwardly, sitting down at their table and quickly busying herself in a book. Why does she even bother reading, Sirius thought to himself.

Sirius started to get bored, watching James and Lily talk wasn't the best use of his time. So he stood up, saying bye to Peter and Remus.

"Well it seems that the deer has finally got the doe!" Remus joked before Sirius could leave.

"Oh deer, yes." he nodded, laughing a bit. Peter and Remus started laughing as well, but it seemed that Lily and James didn't hear, they were too deep in their conversation.

"Do you two wanna come with me?" Sirius asked but both of his friends shook their heads.

"I would but watching Prong's relationship is very deer to me." Remus said sarcastically which earned a lot of laughs from Sirius and Peter. Lily and James looked up from their conversation and both shared confused looks at the boys laughing.

"Catch ya guys later then!" Sirius said and walked away.

Sirius decided to go hang out outside, the weather was still nice and he decided to go and enjoy it before the nice warm weather turned cold with the upcoming Winter.

Sirius laid down in the grass and looked at the sky, he relished the warm breeze and the soft grass.

All that joy was taken away when he heard footsteps and a familiar voice calling his name, he jolted upwards, staring at the figure in front of him.

"Oh well lookie here, it's Snivilous." Sirius said sarcastically, standing up.

"I'm kind of over that nickname." Severus announced and took out his wand, it tip pointed at Sirius. "Also, why are you alone? Did your stupid friends abandon you?"

"Nope." Sirius growled, " They are eating lunch and I decided I wanted some alone time."he declared, "and I also wanted you to know that James got the girl you like, Lily."

"You act like I don't know that…" Severus scowled. He lifted his wand up, mouthing the words , Stupefy.

Sirius shot back, hitting the tree that was behind him. He stood up, quite winded. He stood up, "Expelliarmus!" he shouted. Severus's wand shot from his hand, and Sirius picked it up, throwing it down into a gully.

"It would've been funnier with your three idiodic friends," Severus growled, going to retrieve his wand.

Severus aimed a spell towards Sirius, but he blocked it with a countercharm.

"You know, I don't know why you hang out with Jame's pathetic excuse for a wizard…"

"I know you're just jealous he got Lily," Sirius growled, throwing another charm at his enemy.

"And then there's Peter, surprised how you would let him trail after you, he's just a chubby boy, with alot of dumbness in that fat head of his."

Sirius scoffed and flung back at a spell that Severus threw at him. He stood up, noticing blood on his school cloak.

"And then there's the last one," Severus said darkly, he quickly muttered expelliarmus under his breath. "Remus…"

Sirius gasped and launched another spell at him.

"There's something wrong with him, every month he leaves and comes back covered in scratches… And I'm going to find out what!"

The two boys started aggressively sending spells at each other, not stopping, until Sirius fell in the gully. He stood up coughing up water and he glared at Severus.

"YOU KNOW WHAT! YOU ARE THE BIGGEST JERK EVER! I'M HAPPY JAMES GOT LILY AND NOT YOU! AND ALSO DON'T YOU DARE TALK ABOUT MY FRIENDS LIKE THAT!"

Rage Burned in Severus's eyes.

"You know what!? I'll tell you where Remus goes every month! You wanna know! Do ya!"

Severus stared at Sirius in anticipation, Oh you really want to know! Sirius thought, Well you can have it!

"Ok, tonight, when the moon is at its fullest, you can go to the whomping willow, press on the smallest root to freeze the tree, and then go through the tunnel and you'll find what you're looking for…" Sirius growled.

I don't care what happens to that jerk, Sirius thought, running back towards the school, leaving Severus staring at the tree…

JJJJJ

"You told him what!" James bellowed, throwing his hands in the air in utter shock and anger. I can't believe he'd tell Severus that, Jame's thought…

"It's ok, it's not like he'll get killed." Sirius explained.

"What! He'll probably get killed!" James said, "And do you know how Remus will feel if he killed someone!" James began pacing. "He'll never forgive himself and it'll be your fault!"

Suddenly, the door to the dormitory opened and Remus walked in.

"Are you talking about me?" Remus walked into the room.

"No…"James shot a glare at Sirius and walked over to where Remus stood. "Come on, let's go hang out in the common room. Let's have some hot chocolate."

They both walked out of the room and walked down the spiral staircase that led to the cozy room where there were lots of beanbags, couches, and a fireplace which would calm even the most stressed wizard.

The two friends got seated on a couch, drinking the warm hot chocolate from their favorite mugs. Remus doesn't know what Sirius told Severus, James thought, sighing… But then, an idea came to his mind. What if he could find Severus and stop him before it was too late?

"Remus, I have to go, me and the others will come when it's almost the full moon."

Remus nodded, snuggling deeper into his blanket, and took a long sip of his hot chocolate.

Remus was safe as long as James could stop Severus, but what if I can't? He thought, suddenly overcome with worry. Well, I have to stop him, there's no other choice is there…

James ran through the hallways not stopping to greet any of his friends. Suddenly, Lily came into view, and James only stopped then.

"Hi … Lily -" he huffed, completely out of breath. Why do I have to be out of breath! He thought, I don't wanna embarrass myself!

"What are you doing?" she questioned, cocking her head a bit to show her confusion.

"Something… Something important, I'll tell you later." He said, but he wouldn't be telling Lily.

"Well it seems you got stuff to do," she said affectionately, kissing him on the cheek and strolling through the hallway, her reddish brown hair blowing behind her.

James whistled, but then noticed that he had been lollygagging, he checked his watch and noticed that he only had thirty minutes. Oh no!

He began running in the hallways so fast that he crashed in Regulus, they both toppled to the floor.

"Sorry! So sorry!" James huffed, getting up, and then helping Regulus up.

Normally, James would be mad at himself for crashing into someone, especially if he was their friend but he was actually grateful this time. In fact, Regulus was a close friend of Severus.

"Oh Regulus I'm so glad I ran into you!" James beamed and Regulus looked so very confused. "Have you seen Severus? I really need to talk to him."

"Oh, Severus, he was just muttering about the whomping willow earlier in the Slytherin Common Room earlier but I haven't seen him since… sorry…"

James cursed under his breath, he checked his watch again and noticed that he only had 22 more minutes. I don't think I'll be able to find him in time…

"Thanks anyways." James said quietly and began running again, desperate for some sign of Severus. He explored a lot of the castle, and then he glanced at his watch. Five minutes!

James yelled a curse word and began running faster than he ever had in his life. His lungs felt they would explode and his heart was beating so fast that he thought it would burst from his chest at any given moment.

Four minutes left!

James ran outside, stopping for a quick break to catch his breath, he spotted Snape in the distance, he was far but maybe if James ran fast enough he could stop him?

Three minutes left!

James was almost there, and Severus didn't look like a tiny speck any more. As much as he hated Snape, he knew he had to stop him. For Remus's sake, and so Snape wouldn't get killed.

Two minutes left!

"Snape!" James yelled at the top of his lungs, "Snape! Stop! Don't go in there!" James yelled even louder, so loud that he became dizzy a couple seconds later.

"Yeah! Make me!" Severus sneered and started walking towards the whomping willow…

RRRRR

Remus sat in the shrieking shack, his fever was so high that he felt he would pass out, and his body ached so bad that even sitting hurt. He rocked back and forth on the bed waiting for the full moon, it would only be a few minutes. He was worried because his friends hadn't come yet… Normally, they would accompany him to the shrieking shack, turning into animals once they got there… But where were they? He thought, he remembered James promising he would come…

Suddenly, the floor of the shack glowed and the moonlight spilled into the shack through the window, terror gripped him as sheer pain spread through his body as the transformation began.

His hands were curling into paws, long, sharp, nails, growing from them. Fur was appearing all over his body and his head began transforming into a wolf's head, he tried to fight the urge to transform, but he never could, his wolf mind started to take over… He tried so hard to keep his human mind, but with every second he would become less and less human.

The painful transformation was finally over, he jumped off from the bed, landing squarely on all four feet. He looked towards the ceiling and let out a long howl.

He began scratching at the wall, desperate to get out, but it didn't work and the effort just made the wood splinter.

Remus paced, occasionally howling in agony, or anger. He tried again, clawing the wall with all his strength but the wood ended up just scratching him, causing blood to start spilling from his leg. He whimpered, and began pacing again, making louder noises with every second.

Suddenly, a smell came to him. He opened his mouth to take in the scent, it was a human scent… and it was coming from the tunnels…

Remus trotted towards the stairs a bit reluctant to go down, he set one paw firmly on the first step and it made a creaking noise, he whimpered and his second step causing one of the steps to break, he tumbled down the stairs. His ribs were hurting so bad now and blood was pulsing from a wound in his side. He limped towards the tunnels, the smell was much stronger, a growl formed deep down in his throat, sounding like the rumble of a muggle car engine.

He limped down the tunnel and kept going until the scent was so strong that a drool was forming at the sides of his mouth.

There, at the end of the tunnel he saw two people, yelling at each other, suddenly both gasping when they looked in his direction. He began limping, faster, though it hurt ever so bad to do so.

"Werewolf!" one of the boys shrieked, "Remus is a werewolf, wait till Dumbledoore finds out!"

The other boy grabbed his arm, glaring at him. Remus was so close now, he stood up on his hind legs, opening his mouth and letting out a shrill sound.

"Moony, it's me, james…" One of the boys said something about it was familiar… Remus's human mind urged him not to hurt his best friend, he tried so hard not to but he lunged at James, knocking him to the ground, and blood started spilling from his arms.

"Snape! Get back right now!" James shouted, saying Stupefiey, and Remus was launched back, hitting the wall, he whimpered.

"Sorry Moony…" James said, casting a shield spell, him and the other boy backed out from the tunnel, and James closed it with a spell.

Remus howled in anguish, clawing so hard at the door that his nail ripped off, he whimpered, and didn't stop trying…

JJJJJ

"Can one of you explain what happened?" Dumbledore said, shooting a questioning look at all the kids seated in the room.

Lily, who was sitting next to James just shrugged and James stood up. Sirius shot him a pleading look but James shook his head, I'm not siding with you…

"Sirius told Severus to go to the shrieking shack so he could know what happened to Remus monthly -"

"What do you mean? What's going on?" Lily asked, clearly confused about what was going on.

"Remus is a werewolf…" James growled, his gaze directed towards Sirius and Severus. Sirius just looked at his feet, shifting them uncomfortably. I'll deal with him later, he thought, giving Sirius a glare.

"Awww, poor Remus!" Lily said sympathetically.

"Remus should be expelled sir!" Severus said, standing up abruptly.

"No, he will be staying at school as far as any of you are concerned." Dumbledoore said calmly as James breathed a sigh of relief, and he saw Sirius do the same. "You two must promise not to tell anyone about his condition. Understood?" Dumbledoore told Severus and Lily.

"Of course not!" Lily exclaimed then she looked at Severus who had doubt in his gaze.

"I mean, I don't know, I mean he's dangerous!" Severus announced. Lily shoved him hard in his side, and he growled.

"Fine…" He declared, clearly not happy with his own answer.

"Good." Dumbledoore said, standing up, "You all may leave now." he ushered the four kids out of the room and shut the door behind him.

Sirius walked up to James and James just stared past him, not wanting to talk.

"Um… James, can we talk please…"

"No Sirius, you made the stupidest choices today and I'm not really ready to talk to you yet." James began walking away.

"Come on! Remus should be the one mad at me, not you!"

"Well, you were a really bad friend and you could've got one of your classmates killed! How should I feel comfortable with you right now?"

Sirius sighed, looking a bit defeated, and at that moment James couldn't help having a twinge of sympathy towards his best friend…

The second morning came, James rushed to the hospital wing to see how Remus was doing. He was hoping to see that he was ok and that he would forgive Sirius, but when James walked into the quiet room where Remus lay, he suppressed a gasp of shock when he saw how badly wounded he was. The nurse had told him he had fractured his wrist and three of his ribs, and had countless scratches. Madame Pomfrey had told James he should probably let Remus rest but Remus insisted that James stay. So, for the entire day Jame's just sat on a chair next to Remus's bed, reading a Quidich magazine as his friend slept.

Knock, knock, knock.

James opened the door and saw Regulus standing in the doorway, and for a split second he thought it was Sirius, whom he would have closed the door on right away.

"Oh, it's you… What do you want?" James asked Sirius's brother.

"Have you seen Severous? Haven't seen him all day."

"Oh me? Not since -" he was cut off when Madame Pomfrey walked up to the two boys.

"Severus was in here a few hours ago, had a nasty bit of a shock that lad, I gave him some medicine for it so I reckon he's sleeping right now." the nurse told Regulus before leaving the room.

"Shock? What happened?" Regulus cocked his head and then stared past James and looked right where Remus was sleeping. "What happened to Remus!?"

"Nothing you should be concerned about, now run along." James said quickly, ushering him out of the room.

SSSSS

Sirius had been overcome by guilt ever since the incident. He didn't see James all day and was worried if maybe James didn't want to be his friend any more.

Sirius decided he would visit Remus in the hospital wing, maybe he could ask for an apology. He grabbed a large bar of chocolate to give him and started making his way to see Remus.

While on the way there he saw Lily, talking to one of her friends.

"Evans," Sirius nodded politely.

"Off to visit Remus aren't you," she said, not in her normal, friendly, playful voice, but in a darker voice…

"O-oh, yeah? Why? Wanna come?"

"I don't think he'll want to see you, and James wont be thrilled either…"

Sirius ignored her and finally got to the hospital wing, he flung the door open and smiled.

"Hey guys! I came to visit!" but he noticed that Remus was fast asleep and James was snoring quietly on a chair next to his bed.

"Oh…" he was about to walk out when Remus woke up. "Oh, um. Hi Remus! Thrilled to see me?" but there was none of Remus's normal affection in his eyes just anger, and sadness.

"Not at all…" he growled quietly and James woke up.

"Oh you're awake!" Then he looked towards Sirius and frowned.

"I came to visit. Do you have a problem with that?" Sirius asked, hurt.

"You know Remus didn't want you coming to visit," James said, standing up, standing in front of Remus's bed.

"I wanted to give him this and I'll be on my way…" Sirius explained, setting the large chocolate bar in Jame's hands and walking out the door. "I'll talk when you both are ready…"

RRRRR

Remus had been mad at Sirius, more than mad actually. Hurt…. He thought that Sirius was his friend but would a friend really do something like that?

James handed Remus a bar of chocolate with a note on it.

"From Sirius I'm guessing?" Remus said and James nodded, laying down on the edge of Remus's bed.

Remus picked up the chocolate and took the note of it, it read , Dear Remus, I'm so sorry for what happened. I was a terrible friend and I understand if you don't want to be my friend anymore… I got chocolate for you, I know it's your favorite :)

For a split second, Remus felt a flicker of hope, but only for a moment, Remus knew that Sirius might have not completely meant for this to happen, but it would take more for Remus to get his trust back in his former friend.

The End
