'I've been through hell. Exams and revision have chased me through my free time and in result I have had a long period away from Fanfiction. I'm sorry for not updating sooner .

Here, in England, Kate and William and due to be married tomorrow :D can't wait! I have BBC 1 ready and waiting for me.

Hope you enjoy the story and I haven't forgot Moonie Magnolia, for all the help you have given me. Your stories are so inspiring and I hope that maybe one day I might be nearly as good as you I owe you so much for all the time you've lent to helping me make this story betty, and I'll try to write longer chapters '

Three hours later, with Sam locked down in Bobby's home-made panic room, they waited anxiously for the moment to strike, the moment when Sam would become a monster, a supernatural being with a craving for human flesh.

Dean felt heavy, weighed down by tall the emotions that were coursing through his body. One minute he was angry at what his brother was about to become, next he was sad, trembling for his baby brother. By the looks of it Bobby shared the same feeling, though he managed to keep a game face throughout.

Bobby finally noticed Dean had been staring at him and gave him a comforting pat on the shoulder.

: Don't worry son, Sam will be…" Bobby didn't know how to finish.

…SN…

Sam was also fighting a war between his emotions, though his mind was somewhere else. He was nervous, scared for what he was to become. The fact he couldn't do anything to stop it scared him witless, made him feel defeated, like he was dying.

"I never wanted to go out this way" He found himself saying out loud, not taking his eyes of the thick iron floor.

Dean stood just behind the peephole, keeping his game face throughout.

"Sam…"

"I should've been fighting, shot perhaps, but not this, anything but this…."

His brother stared, not blinking.

"Dean there's still time, shoot me"

"No Sam…"

"Dean, I don't want to become that thing, I'd rather be dead"

"No"

"Dean please! I can't do this…just shoot me!"

Dean shook his head.

"Bobby then!" Sam couldn't see the older man but somehow he could sense Bobby's presence.

"Bobby please..Dean won't but you can…please…"

Bobby sighed sadly, the kid didn't deserve this. Not one bit of it.

"I'm sorry Sam…"

"No you're not! You know it's the right thing to do yet you won't do it! Please Bobby, just..just do it…"

"Look son, I know you feel like giving up right now and I can understand that but believe me when I say you can get through this. I have a friend just outside Washington…his name's Luke. Had Lycanthrope since I can remember and he's still out there hunting, a wife and two kids too."

Sam shook his head in disbelief.

"No, I'd rather die"

Bobby gave up; the kid had been pretty stubborn since he was a toddler. His brother too.

"sam…listen, I'll help you man but just…please just try for me…" Dean pleaded, hopi nghis brother ould see sense, and realise that maybe there was hope.

…..SN…

Sam was going to reply but he was suddenly overcome with a feeling of acceleration. It was as if his body was on fire. He heard his breath quicken and with a sudden burst his senses exploded.

"Oh god…"

The room was no longer quiet. Noise swarmed the panic room, music, engines of cars, even dogs barking from at least a mile away, but what freaked Sam out most was the steady beating of a drum, or two of them.

"Sam!" Dean reached for the handle as he saw his baby brother squint in discomfort but Bobby laid his hand on his, telling him to stop.

….SN…..

The drum beats grew faster, and with upmost horror Sam realised that they weren't drums at all, but the sound of his Brother's and Bobby's hearts beating. His urge to be sick was overthrown by his backbone popping, causing him to double over. The pain that followed was unbelievable and had Sam crumbling onto the wall.

"Sammy!" Dean couldn't take it, his first instinct was to rush in there and take his baby brother's pain away. Once again he reached out for the iron latch,

"Dean Stop, let him be, there's nothing you can do for him now!"

Dean knew Bobby was right but how could he just stand there and watch his brother go though complete agony?

"Dean I know this must be hard, for you and your brother.." Bobby said glancing back at Sam who was still leaning up against the wall, groaning as his back bent over.

"But you must be strong, for yourself and for Sam" Dean looked at Bobby through tear filld eyes, and knowing he was right released his grasp of the latch and took a step back.

…..SN….

Sam could hear voices, but he didn't care what was being said, the pain had reached up into his head and god knows he screamed. He screamed so hard his throat became sore in seconds.

The pain grew, becoming stronger and spreading throughout his whole body like an infection. He tried to scream, but found he wasn't able to make a single noise. His eyes widened, not at the fact he could no longer scream, but the way his hands had changed shape: They were no longer the long, human hand he was used to, for they had thickened and instead of his own blunt nails there were three inch long claws ending on his fingers. He watched at the thickened pads (previously soft, human flesh) grew darker and became much firmer.

Dean didn't know how much more of this he could take; his brother had grown claws for god's sake! Every time to look at his bother through the small window built into the iron door all he could see was Sam in pain, while turning into the very thing they hunted.

So when Sam started screaming Dean found himself drained, mainly of hope for his little brother and the fact that if he watched anymore he would loose all sanity and race into the metal cage to fix his brother, make him all better again.

Thankfully Bobby was there, in a small way letting Dean know he wasn't alone, that some else watched over his brother too.

He looked to the older hunter, his eyes stinging painfully as he forced back freshly made tears.

"I-I don't think I can do this Bobby"

The bearded man gave him a pitiful look and nodded, his own eyes welling up, but when it came to crying Bobby was even better at hiding it than John.

"Don't worry son, we'll manage this, first times the worst." Remembering when he had witnessed Luke's first transformation. It hadn't been a pleasant sight.

…SN…..

Sam couldn't see. He had closed his eyes and found he didn't want to open them again, feared at what may have become of the rest of his body. The pain had eased a little but that didn't mean it still hurt like hell.

Suddenly a load crack was hurt and Sam collapsed to the ground, wincing as he did so. Finally, he opened his eyes, shocked as he witnessed his legs bend and re-nit into a new shape.

He watched in horror as his ankle grew away from the ball of his foot, his attention was then back to his foot where his toes had reshaped and become more paw-like. Each toe ended with a sharp claw suited to latching down into the ground and grabbing onto prey.

For a second Sam looked away, trying to catch a sight of his brother, but gasped when he felt an itching sensation make its way over his skin. He looked down at his abdomen and too his horror a coat of dark chocolate brown fu r had spread gown his whole body.

Then suddenly everything seemed to stop, as though time had come to a halt.

Just as Sam had thought it was all over his face became burning hot, as though it were on fire. He tried to scream but all that came out was a mix between his voice and the roar of an animal.

'oh god..' Sam thought as he felt his face change shape. His ears elongated and his teeth grew, from useless molars to long, impressive canines, just right for ripping and tearing into human flesh. He looked round to see a thick, bushy tail lying helplessly behind his legs.

'NOOOOOO!' Sam shouted in his mind again, as his newly grown muzzle did its final alteration and stopped growing. He wanted to shout but it came out as a loud bark instead, and then his sensitive sense of smell latched onto the one thing he craved for, prey.

….SN…..

"Bobby I…" Dean was far from okay. Sam didn't look like Sam anymore. Sam looked like a mix between man and wolf, the perfect hunter. The creature seemed angy and barked up at the ceiling, its white fangs showing off their size and sharpness.

"I think we should go now, that's not Sam anymore."

Dean looked at Bobby and nodded in agreement. That definitely wasn't his brother anymore. Sam didn't growl and he certainly didn't bark. Yet he wanted to try something.

"Sammy, you in there?" The wolf probably didn't even understand him, but it did turn its furry head to face the older brother. The sharpness of those yellow eyes sent a shiver down Dean's spine but he remained strong, for Sammy's sake.

"Sam…" The wolf just stared at him, tilting its head to the sight like an overgrown puppy.

"Dean I…."Bobby began.

"Wait a minute, I think he-" Dean's response was interrupted by a ferocious growl and all of a sudden the wolf leapt down on to all fours and ran at the door, snarling when the iron shield didn't budge.

'Definitely not Sam' Dean's mind reasoned.

"C'mon boy, let's go" Bobby began climbing the stair case. With his Shoulders hunched not looking back down at the brothers.

"See ya soon Sam…Just don't do tearing yourself up, okay?"

All he got in response was a threatening growl. He sighed as he wondered.

'What on earth were they going to do now?'
