DISCLAIMER- I do not own any of the character that are in this, except for the characters that I create myself.

Severus Snape had an ambitious desire to discover where the teenage Remus Lupin went every full moon. He had just received knowledge from Sirius Black that if he touched a knot on the Whomping Willow, that would petrify it and there was a secret passage under it. Perhaps it had something to do with the reason the werewolf looked pale after every full moon and would usually miss classes for a day or two afterwards. Severus had no idea that Lupin was a werewolf, but he was just about to find out.

He was sitting in Potions class, listening to Slughorn aimlessly describe a blood-replenishing potion that they would be making that class, since it was double potions. It was sixth year so thankfully the dunderheads had been weaned out but to Severus's dismay, Potter and Black were in it. So was Lupin and Lily, but Lupin wasn't here, presumably "sick". He shot a quick smile towards Lily, but it remained unreturned for she reviled him for what he accidentally called her last year; a mudblood. Severus regretted it as soon as it slipped out of his mouth, yet even he couldn't forgive himself. He had lost the only person who truly cared about him and without Lily, he was no one. To make matters worse, the fiery red-head was succumbing to the charm of James. Severus completely hated James. The only thing that the glasses-wearing, messy-haired boy was good for was to inflict pain upon him.

Slughorn kept on rambling on and on about the blood replenishing potions, causing Severus to become bored. He was way too smart for this basic first-year knowledge and he craved more challenging material. He wanted a career as a potions master, a quaint and quiet career that would allow him to work at his own pace. He sighed with loneliness, he was the only person in this class that would be working without a partner. The dunderheads in his house dropped out of this course as soon as they could, meaning that they could focus more on working for the dark lord. Severus was tempted to join the dark lord, no one ever cared about him; except for his mother and Lily, but they were only two people. The rest of the people at Hogwarts wanted nothing to do with the greasy-haired kid.

It wouldn't really matter if Severus worked by himself- he probably could do better than anyone in this class combined. Even if there was a lot of people. Severus knew that he could easily outsmart these people. Looking around, Severus noticed that Slughorn was wrapping up, meaning that everyone would start working together. He did a quick headcount and Severus realized that there was an even number of people in the class, given the fact that Remus was missing. Sighing, Severus realized that he would not be working alone, left to his own devices. He saw everyone else pair off and realized that Lily was left without a partner. Sirius had persuaded James to work with him.

Sighing, Severus walked over to Lily Evans, where her face was quickly becoming the colour of her hair. She did not want to work with Snivellus. As far as she was concerned, their friendship was completely over and she wanted nothing to do with the greasy haired kid. Little did she know that Severus was the complete opposite, he wanted to fix his damaged relationship with the beautiful, green-eyed girl. "I guess I'll cut up the ingredients and you put them in the cauldron, since you're the best at that," Lily sighed, wanting to work with her best friend Emmeline Vance, but she was working with Marlene McKinnon.

"I'll do that," Severus replied, nodding his head as he started to boil the water in the cauldron. He wanted Lily to forgive him, to allow him to be her friend once again, just like their first year at Hogwarts. Back then, they were extremely close, not letting the inter-house rivalries get in between them. Yet Severus's interest in the Dark Arts allowed their strong bond to falter and shatter apart as the two former friends slowly became enemies.

Lily nodded her head, ignorant to the fact that Severus was trying to ameliorate things in between them. She also didn't know that Severus was doing something extremely risky that could lead to his death that night. She didn't know that the greasy-haired boy was planning on following Remus to the shrieking shack. Heck, she didn't even know that the sandy-haired boy was a werewolf, despite the two of them being quite close. After ditching Severus, Lily became quite close to Remus, yet she didn't know that he was a werewolf.

Eventually the two former friends finished the potion. Severus took the honours of bottling it and placing it upon Slughorn's desk. Lily took the time to clean up, a little annoyed at the fact that Snape wasn't cleaning. He did most of the brewing so I guess it's only fair for me to clean up. Even though if I were working with someone else, they would be helping out. Especially Remus. Had the two of us been together, we would have been a dynamic duo, possibly better than Snape could ever be. What am I thinking? Snape's like a teenage potions master. Too bad he's turned to the dark side. He would have made a great healer, Lily thought to herself, her eyes bearing into the obsidian eyes of Snape.

Soon enough, class was over and everyone began to head their separate ways. Snape was excited for it to be the last class of the day, he was going to find out where Remus would disappear off to every night of the full moon and figure out why he did it. Thanks to Sirius- Black, he would be able to find out why Remus would disappear and tell Dumbledore. Surely, if Remus were any danger to Hogwarts, Dumbledore would expell Remus, right?

After sitting in the Slytherin common room for what seemed like hours, Severus looked at the clock on the wall. It was eight thirty and the full moon would begin to rise soon. Putting down the potions text that he was angrily reading (it had way too many errors for Snape's liking), Snape went up to his dormitories to prepare where an unpleasant surprise was awaiting him. "Hey Snape," called Mulciber.

"Hey Mulciber, I need to get ready. I'm going on a walk tonight," Severus whispered, not wanting anything to do with what the future-death eater. He was clearly planning something and Severus didn't want anything do do with it.

"Oh, where you going?" Avery asked, his beady blue eyes flashing with excitement.

"Nowhere, I just need to clear my head."

"Oh, did that mudblood you worked with in potions cause someone to get a little heart-broken. We all know you used to fancy her, chances are you still fancy her. She's a filthy mudblood. You have better friends in us!" complained Mulciber who had probably learned about Severus's partnership with Lily in potions from someone else. Perhaps he had learned from the Marauders himself, but Severus remembered that his 'girlfriend', who was in potions, had most likely told him.

Severus grunted something inaudible and walked out of the dormitories into the Slytherin common room. Seeing no one he wished to recognize, he headed out of the dungeons. His mind was unusually calm as he walked up staircases, ran down hallways, and disturbed several painting. He encountered a group of first-year Gryffindors when he began to approach the Great Hall and sent them a look that could make Dumbledore wet himself. Ten points from Gryffindor, Snape thought to himself, Curfew is in half-an-hour. The three of them ran off, nearly screaming. Smirking, Severus continued on his way and reached into his pocket for his wand, which was still there. The greasy-haired boy sighed in relief as he ran out of the front doors of the school. Even if he weren't going to the whomping willow, Snape was severely in need of fresh air.

The quiet November evening had a peculiar smell to it, something like blood and Severus thought he could hear something similar to the screams of a human. He ignored this, blaming it on the insanity that lurked within. Having an abusive father and no friends really did a lot of damage to someone. No one, not even the strongest witch or wizard could deal with it for extended periods of time. His beat up shoes squelched against the moist grass- it had rained earlier that day. Severus felt truly at peace out here.

The moon was almost risen and Severus could almost see it trying to peek its head out of the clouds. Distracted by the sounds of his shoes, Severus didn't realize when he had reached the whomping willow until it was almost too late. Mentally cursing himself, he ran off to find a stick. In the distance, he thought he could hear someone who sounded a lot like James. Blaming that as well on the insanity, Severus found the perfect willow-poking stick. He found the knob on the thrashing tree, barely dodging a rogue branch that had the intent to knock him out. Once that knob was poked, the willow stopped thrashing and Severus easily found the hidden passage.

The passage itself was cool and damp, causing Severus to shiver, despite him wearing his winters robes. It probably had to do with the fact that the greasy-haired kid was nearly starved to death while he was at home and found that he was unable to eat large portions of food at Hogwarts, even after three months. His stomach was simply unable to adjust to the larger portions of food.

He heard screaming again and was beginning to think that the screams were real. In the background he was beginning to hear James's voice. He did not want James to see him and attempt to get the greasy-haired kid in trouble. Every Slytherin knew that Dumbledore clearly favoured his own former house, Gryffindor, and would take a Gryffindors side over a Slytherins, even if the Slytherin had done nothing wrong. Dumbledore would probably assign Severus detention with Filch for a month.

Hearing the voice of one of his worst enemies, Severus kept on running forward. He did not want James to ruin this for him. He entered a building that had blood on the walls. Fearing for the worst, Snape pulled out his wand. He could be a hero and maybe he wouldn't be bullied again. Maybe Lily would be his friend once again. Maybe the Marauders would leave him alone. "Let them go," said Severus, firmly and boldly as he stared at a grimy window which showed the moon.

His eyes were met by an amber pair.

He could smell the presence of a human and there were many emotions that lingered with the scent. Bravery. Fear. Heroism.

Perhaps the strongest emotion that he could smell was hope.

It didn't matter to him, all he wanted was more human blood, enough to sustain him for one more moon.

He had a particular thirst for the blood, he wanted more and more of it.

The werewolf noticed that the sense of fear was getting stronger and stronger.

The human muttered out something that summoned him, made his taste for blood grow stronger with each passing second.

Following the scent, his eyes lingered on an obsidian pair.

He attacked.

James could hear screams as he ran to the shrieking shack. They did not belong to Remus, nor did they belong to anyone he knew. He had ran ahead of the other Marauders; previously that day, Sirius had told him that he had told Snivellus how to get into the Shrieking Shack. Fearing the safety of the werewolf -he knew Snivellus would tell the entire school about Moony's secret-, he transformed into Prongs, who had a faster running speed. He ran and ran and the screams kept on getting louder and louder. The howls of the werewolf seemed to be getting more prominent, as if the werewolf had found a target.

Once Prongs had reached the Shrieking shack, he knew something wasn't right. He transformed into James and draped his invisibility cloak over him, thankful that the werewolf couldn't see through it, something they had tested out the previous year. The thought of Snivellus slipped his mind and he ran around the Shrieking Shack. He knew that Moony couldn't tell the difference between friend and foe and he knew that Snivellus had probably encountered Moony.

He heard a human scream, someone begging to be killed.

Something definitely wasn't right.

That voice belonged to the one and only Severus Snape.

Despite the greasy-haired boy being his sworn enemy, James knew that leaving Snivellus here would lead to his expulsion. Possibly the expulsion of all the Marauders.

In an attempt to distract the werewolf, James pulled out his wand and muttered, "Petrificus Totalus," and immediately the werewolf grew stiff, unable to move. Using that to his advantage, James ran to the greasy-haired boy. What he saw almost made him vomit right onto the floor in the kitchen of the Shrieking Shack.

Severus's normally greasy hair was slicked back with crimson blood, there was a gash on the side of his face which was bleeding slowly but steadily. There was a huge tear in the abdomen in the robes of Snape and that was profusely bleeding. He noticed how underweight the boy was, he clearly wasn't eating enough. Where his sleeves were rolled up, there was a huge gash followed by paled white scars, followed by some fresh scars. Snivellus has a self-harm addiction, James thought to himself, finally realizing how badly his bullying impacted the boy. He didn't know Snivellus was addicted to hurting himself.

"Please...leave...me...here...to...die...don't...want...to...be...a...were...wolf," Snape gasped, hoping that James would take the message and leave him where he was.

James ignored Snape and picked up the boy, carrying him in a cradle carry. He had to go to Madame Pomfrey. James ran out of the Shrieking Shack, carrying Snape, ignoring the cries of pain and protest that Severus was making. Once he was a suitable distance away from Moony, he took off the invisibility cloak and faintly heard the voices of Peter and Sirius. Casting a quick Lumos, to brighten things up, he gently took off Severus's cloak and was about to take off the shirt when Severus screamed and begged, "Don't...take...off...the...shirt...there...are...scars...my...dad...whipped...me...with...a...belt...too...many...scars..."

James's heart broke into multiple pieces. He had never had a glimpse into abuse and never wanted to. His parents had never failed to express their love to him and he thought that's the way all families were, except for Sirius. He didn't know Snape's family was like this either. He ignored Severus's pleads and took off his shirt, which had a hole in the abdomen and he staunched the flow of blood with it, ripping the cloak of the boy into a few pieces. He gently used that to hold the shirt in place while he waited for Peter and Sirius. The two of them could help with Snivell-Severus.

Finally, they arrived. "I need your help carrying Severus back. Moony bit him. I'm sorry, I didn't get to him in time," James cried, letting a single tear fall down his face. Had Severus never been attacked by Moony, he would have continued bullying Snape, not knowing what the Slytherin was going through at home.

Sirius immediately went pale, realizing that it was his fault that Snape was bitten. He knew that James never cried. To make James cry, something serious had to happen. He realized that there was more to Snape than what meets the eye. Clearly James had to have figured something out about the Slytherin that no one except Lily knew. He reached into his bag and pulled out some silver powder and some essence of dittany. "These will seal the wound, without these, the wound will never heal and bleed continuously until he died. I kept these on hand in case one of us ever got bitten," Sirius announced.

"That means...he'll become a werewolf..." Peter whimpered, wanting nothing more than to run away and go back to bed. The rat animagus stayed brave and continued staying where he was, despite feeling like he was going to vomit all over his best friends.

Severus screamed as they put the combination of elements onto his cuts from Remus, screaming louder as the two elements caused the cuts to seal up immediately. James picked up Snape who whimpered in pain and they headed up to the hospital wing, unaware of the consequences that followed their actions.

Hey, I hope you all enjoyed this! I know I've been wanting to read a fanfiction like this for a long time and I couldn't find one. That made me decide to write one myself.

Next, the Marauders confront Sirius about his actions and a little bit of Snape angst.
