Still don't own Supernatural. Not suing would be appreciated. I have no money, I promise, so please just let me use the brilliant characters.

Thanks for the reviews. (this is my first, angsty, teen sam fic, so if I'm not doing it right, let me know) I also know that there hasn't been a lot of Dean, but that should be chaging within the next chapter or so.

Sam is 15, and Dean is 19

-/\-SN-/\-

The icy rain fell harder, slowed by the thick leaves overhead, but not enough to make a difference. All three were soaked through and wanted to finish the job and get home. Sam's jaw was set in anger as he silently counted down the minutes in his head, the minutes until he would be late for meeting with Matt.

John glanced back at his boys. Sam looked up at him, the boy's eyes hard and steely. The last few weeks hadn't been easy for John either, he didn't know how to talk to Sam anymore. Everything he said to his son was either responded with anger or indifference. Ever since his son had turned thirteen, they had stopped being able to talk to each other. Two long years with Dean having to be the buffer between them.

Sam stumbled over a rock and caught himself before he fell to the muddy ground. He angrily kicked the rock away and shoved his hands in his pocket. Dean fell back next to his brother.

"You doing okay?" He muttered.

Sam nodded and shivered a little. He almost told Dean about Matt's call, but knew it wouldn't change anything. He pushed under a low branch and jogged a few steps ahead of Dean.

They reached a small trail after thirty minutes of trudging through the forest. Sam glanced down at his watch, two minutes to meet Matt. John stopped and pulled his notes from his pocket. Dean stood close and looked over the documents with John, Sam stood a few feet back and leaned against a tree. His eyes were on the wet ground and his arms folded across his chest.

"Sam."

He looked up at his father.

"You ready?"

He nodded, still refusing to speak to his father.

"Let's go."

Sam pushed away from the tree and fell in step behind his brother and father. He tripped over a root and fell to the ground. He swore under his breath and pushed himself back to his feet. His eyes caught on something crumpled on the ground. His fingers trembled as he realized what he was reaching for. It was the Batman comic that he had seen Matt reading at lunch.

He picked up the sodden pages and carefully straightened them.

"Sam." John called from further down the trail.

Sam ran towards his family, the comic clutched in his hand. He met up with Dean and John where the rail widened out slightly. He realized he was close to the climbing tree and he suddenly knew that he had to meet Matt, it was important. He looked down at the comic in his hands as John and Dean looked over a map in an attempt to plan the best way to find this thing without being ambushed.

Sam took a few steps away, but nobody noticed. He glanced back and then ran into the woods.

"Sam!" He heard John yell, but he didn't slow.

Sam ducked under branches and stumbled over rocks as he sprinted through the forest. He stumbled into the clearing and saw the tree, an ancient oak with thick branches perfectly spaced for climbing.

"Matt?" His voice was drown out by the steady cadence of the rain.

He shivered as he scanned the dark forest for his friend. Sam was about to give up when he caught a dark figured huddled near the base of a tree. He ran towards Matt and knelt at his side. Matt was very pale and his eyes were closed.

"Matt?" Sam gently touched his shoulder.

Matt's eyes slowly opened and he looked over at Sam. "You came."

"Are you okay?"

He shook his head. Sam realized how hard Matt was shivering.

"Let's get you out of here." Sam tried to help Matt to his feet.

"No." He pushed Sam off. "You have to leave me."

"Why?"

"There's something wrong with me." Matt's voice broke. "I – I don't know what's happening."

"I can help you."

Matt looked into Sam's eyes. "Really?"

Sam nodded. "Let's go."

Matt stood with Sam's help. He was weak and could hardly stay on his feet. Sam put his arm under Matt's shoulders and helped him from the clearing.

Matt suddenly stopped and pulled himself away from Sam. "Run."

Sam turned. "What?"

Matt fell to his knees in pain. "You have to run, Sam. Please."

He froze, unsure what to do.

Matt curled in upon himself. "Sam. Help me." He gasped.

Sam took a step forward. Matt suddenly tensed. He yelled in pain and Sam froze. Sam watched as Matt changed. The boy grew more muscular, taller, stronger. There was something almost canine now about his appearance. His teeth sharpened and his fingernails turned to claws.

Sam took a step back and for the first time in years, wished for his dad to come back. Matt shot to his feet, his eyes locked on Sam.

"Matt, please. This isn't you." Sam spoke out of desperation. "I know you, you wouldn't hurt anyone."

Matt was the kid who couldn't hurt anything, even if he wanted to, the kid who noticed things that nobody else did, the kid who nobody noticed. He was no longer that boy. He'd kill his best friend, and that's exactly what he had in mind.

"Matt." The comic fell from his hand.

The beast, Matt, ran his tongue over his fangs and smiled. Sam didn't have time to react before Matt pounced at Sam. He felt claws in his shoulder and the sharp pain of them pulling through his skin.

A gunshot rang through the rain-soaked woods and Matt was gone. Sam pushed himself to his feet and ran in the opposite direction for the cover of the trees. A strong arm grabbed him and he turned to fight.

John pulled his son close. "Sam, are you all right?"

Sam looked up into his father's eyes. "We have to help him."

"We can't."

Sam pushed away. "This is all your fault."

Dean grabbed his brother's arm. "Sammy, are you okay?"

Sam pulled from Dean's grasp and turned back towards the clearing. If John and Dean weren't going to help Matt, then it was all up to Sam.

John was only steps behind his son as they ran into the clearing. The woods were eerily silent other than the steady rain. A low growl broke the silence and John grabbed Sam.

"Dean." John looked over his shoulder at his oldest.

Dean came into the clearing, his gun out.

Matt stepped from a shadow and Sam broke free of his father's grasp.
