Alright, so here is a new story. It is an AU/continuation from Heart, episode 2.17 Sam is turned into a werewolf, and it doesn't go over well with his demon blood. Dean has to think in shades of grey, rather than the black and white that he had always known.

The Grey of Night

Chapter 1

Fade to Grey

Sam and Madison slept the day away, celebrating her release from the curse. They had cut the bloodline, and she had remained human for an entire night; it deserved Dean's kind of reward. As they slept, Sam had dreams; pleasant and otherwise. The other dreams were of Madison changing him, and the two of them leaving together to live as nomads; neither of them wanted to hurt other people. The good dreams replayed the scene of the day over, and over again.

Sam awoke from one of the less-than-pleasant dreams to a light snuffling noise, a low groan of pain. His dreams mixed in with the reality around him, leading him back to a dream he had previously seen; one where Madison changes him after the curse was broken. She would change while he was asleep and bite him gently, barely breaking the skin. She would then steal off into the night to await the transformation of her mate.

Sam was pulled from the half-dream when a prick of pain pierced the junction between neck and shoulder. His eyes snapped open to reveal Madison standing from her crouch, directly above him, her lips a deeper shade of red from blood. "Madison?" He croaked, jumping after her as she bolted for the window. Her eyes flashed a steely blue as she growled at him; not threatening him, pleading for him to stay there. "Madison!" He shouted as she jumped from the third story window. He watched as she flipped agilely down to the pavement, using various window ledges and drain pipes to avoid falling.

Sam ran back to dress; he had to tell Dean. He was pulling his shirt on when a blinding pain shattered his arm, shocking him off of his feet. He cried out as he fell, his right hand flying to clutch his screaming shoulder. He could feel nothing but swollen skin; the werewolf venom had already healed the bite, almost completely.

He struggled through his pockets, barely reaching his phone before another sharp spike of pain blinded him. Sam shakily opened the phone and managed to call his brother, his burning fingers pressing several wrong buttons on the way. "Sam?" his brother asked, wondering at his late-night call. "Dean!" Sam grunted through clenched teeth. "Get…Here now! Argh!" His left arm spasmed as another wracking bolt of pain shot through him, causing the phone to fly a good four feet away.

The pain had grown exponentially, piercing every inch of his body with blazing needles. His mind did not register the scuffling at the window, or the soft footfalls that approached him. He did feel as the feather-light touch of fingers brushed at his shoulder, just above the bite. Fire screamed through the spot, like pins-and-needles, only much worse. A whimper went unnoticed above him as he shouted out loud again, voicing his pain.

Madison had returned, her instincts telling her that something was wrong. She felt fire slide briefly up her back, freezing her mid-step. My mate. She thought single mindedly, turning from the man she had been stalking to race back to the building. She lunged at the brickwork, using cracks and windows as footholds to scale the wall of the apartment complex.

She slipped in the window, immediately catching the throbbing heartbeat of her Sam; her mate. She winced at his groans, the pain screeching deep within her, torturing age-old instincts to protect the mate at all costs. She knelt down beside him, brushing just above the faded bite with her fingers. She nearly clawed her own eyes out when he screamed in pain at her touch, scratching at her own arms as punishment.

She had done this; she had killed her mate. Her bite to make him join her, had gone wrong, and was killing him. There had been no danger when she bit him, being as gentle as her teeth allowed her; he had barely even bled. She had raced from the room to stop herself from eating him, his freed blood calling out to her senses. Her instincts denied them though, forcing her away from the one she loved.

Sam screamed again, making her tear out chunks of her hair in response. Her own physical pain felt less than her mental pain when he screamed. Her animalistic mind was destroying itself, tearing itself apart in its inability to protect her Sam, the only thing that she would ever choose above food.

Madison's own consciousness began to bleed through the animal's instincts, causing her to enter an elevated state of awareness. She could sense all around her, using the wolf's senses to give information to her awaking human mind. Sam's screams tore her up, that instinct still more powerful than any human mind could hope to be. She raced to the front room, and faced the wall opposite the door. Sam would call brother. She reasoned primitively, turning to attack the wall with her sharp nails.

BEDROOM HELP SAM

She slashed the words into the wall, the deep gouges clearly readable to anyone who stepped through the door. Madison sprinted back to the bedroom, spotting Sam's phone lying on the floor. She managed to pick it up without crushing it in her shaking hands, her mind barely comprehending the words on the screen. PHONEBOOK. She read slowly. That call Dean. She pressed the button below the word, and glared as the bright light opened a new page. She clawed at the down arrow, nearly breaking the phone as she scrambled for Dean's phone number. Finally she recognized the name, and pressed the green call button.

Madison dropped the phone to the floor, listening with enhanced hearing as it rang only once before Dean's voice called out, "Sam?! Where are you?" She could hear the frantic undertone; even hear Dean's heart beating through the phone. Sam's scream pulled her from her blood-induced haze. She snarled into the phone, the sound becoming a scream as she tried to form words.

Her teeth clenched together in pain at Sam's howls, she clenched her throat to form sounds that her teeth could not. "Gheeng! Hewp! Hram ghying!" She desperately hoped that the man could understand her, the words barely understandable to her own ears. "Madison? Madison, where is Sam?" Dean demanded. Sam's shouts were the only things preventing her from losing her mind as she could hear the frantic beating of his heart. "Aparkmenk!" She growled as her throat began to hurt from the strain that talking put on it. "The apartment? Madison, what is going on?" She heard the sound of the impala's engine picking up speed, Dean rushing now.

Madison had returned to Sam without answering, dragging the phone with her. She knew that Dean would be the only person able to help her mate, Sam's screams digging into her mind. Madison gasped, her head throbbing in pain, as she saw Sam's new development. His veins were appearing in his skin, black intruding upon the normally blue-invisible lines. His skin was spider-webbing with the veins, each tube larger than a hair's-breadth appearing in his skin.

Sam howled with renewed vigor as the lines clawed through his face, a deep network of roots spreading along his cheeks. They reached his eyes, which flew open to reveal yellow corneas and deep black veins running through them. His irises were an icy blue with a black pupil in the center. The pupil resembled a cat's, a vertical slit widening towards the middle. Madison stared in horror as the black consumed his entire eye, leaving just the iris among the pools of night.

His teeth tapered into points, blood leaking from his gums. Madison clenched her arms tight, her nails piercing her skin, once again. She ignored Dean's screams from the phone, demanding to know what was going on. A car door slammed down in the street, causing Madison to fly to the window. She saw Dean racing towards the building, and she flew to unlock the main door so that he could enter immediately.

She slashed at her wrists as another scream from Sam shattered part of her mind, her protective instinct killing her. She was worthless; she could not protect her mate. He would die because of her. She could not survive being such a failure. Her mind tore itself to ribbons, and she howled as she fell next to the flailing Sam, his pain clawing deeper than her nails ever could.

Dean smashed open the door and his eyes immediately flew to the clawed message on the wall. His feet carried him mindlessly to the bedroom, to find a bleeding Madison on the ground, howling at Sam's screams. He gasped as he took in his brother, the black veins stretching out across his long body. Madison's eyes flew to him as she heard him breathe, her eyes streaming with tears.

Sam's breathing stopped. The silence rang through the air louder than church bells. His thrashing had stopped, his eyes closed in sleep. His body was still littered with dark veins, however, preventing Dean from relaxing even the tiniest bit. Madison reached down to cup Sam's face gently, using the pads of her fingers to keep her nails away.

Sam's eyes flew open, and both Dean and Madison were hurled into the nearest wall. "Sam!" Dean cried as Madison howled. He looked and saw glass from a picture behind her splayed on the ground; some of it was obviously digging into her back. Dean returned his attention to his little brother, watching in awed horror at the sight before him.

Sam was fighting with himself. His left eye was entirely black, while his right eye was that of a typical werewolf's. His teeth were no longer pointed, but human. "No, stop!" His mouth cried out while his body thrashed, pinned in place by nothing. No, I will not tolerate werewolves in this body! An awful voice cried into their minds, Sam's black eye flashing in anger. His hand flew to his face, but froze before it could touch the eye. "Dean, help me!" Sam cried out as his hands were thrown away from him as they flew to attack his face.

Sam was hurled onto the bed, his hands and legs forced out onto the mattress. I said stop! The voice cried into their minds. "No, let me have my body back!" Sam shouted to no one.

"Sammy?" Dean asked, struggling against the invisible bonds holding him. He turned to look at Madison, who was staring blankly at the floor, blood dripping slowly from her back. Dean could see her breathing, so he was not worried about her being dead.

Sam managed to struggle into a semi-sitting position, his werewolf eye catching sight of Madison hanging limp against the wall. He smashed his fists into the bed as he cried, "Maddy!" and he flew onto his feet. He lunged at her, but was caught in mid-air by nothing. He shouted again as he was hurled to the ground, smacking his head against the wooden floor.

Sam's eyes flashed back to normal briefly, in which time Sam began chanting a familiar ritual. "Exorcizamus te, omnis immundus spiritus, omnis satanica potestas…" He twitched as his eyes flooded back to their unnatural configuration and his jaw snapped shut, cutting off the rest of the exorcism. Oh no you don't. I don't plan on leaving this body any time soon, and that little nursery rhyme won't do you any good, Sammy boy! Dean shivered as the demonic voice carried through the air like a black cloud. Now for some payback!

Madison began to scream. She jumped from lifeless wall-flower to wailing banshee in a matter of words. Sam howled at her pain, his wolf instincts flaring up against the demon's power. Madison's screams faded as Sam wrenched his body from the ground, snarling as he once again tried to claw his eyes own eyes out. This has got to stop… I thought. I then remembered an exorcism of sorts, used when a demon was too bonded to the body it was in. It's awful to think that Sam is bound this deeply to a demon, but it's worth a shot.

"Somnus te, omnis immundus spiritus, asmatis pro vinculum sententia professio ut is somes," I muttered quietly, focusing my entire attention on Sam and the words coming from my mouth. Sam's body twitched and then froze, his head swiveling towards me. My mouth was clapped shut, stopping the rest of the short incantation. Sam took up another one. "Exorcizamus te, omnis immundus spiritus, omnis satanica potestas-" The demon was too preoccupied with one of us to stop the other. I began chanting again the instant my mouth was free.

"Haud diutius vadum vos torqueo putus animus intus-" I froze as Sam's black eye began to change from black to yellow. My mouth stopped working, and I could no longer draw in breath; Sam was having the same problems. Madison dropped to the ground as Sam's face turned red, his werewolf eye fading into white with a yellow center. I am going to kill both of you. The demon's voice pounded through my skull. Madison crept towards him from behind, her eyes sharp and deadly.

I will destroy Sam and this werewolf in his mind, and then bleed you with his body. I am going to control this boy, and all of his glorious powers. It might even be useful to be a werewolf! I flinched at his words, not wanting my baby brother to be dead before me. I struggled against the invisible bonds, futilely attempting to pull air into my screaming lungs.

Madison chose that moment to break his hold. She jumped forward and landed on his back, slamming her teeth down into his shoulder. She bit deep and hard, wrapping her limbs around his body as tightly as she could. Sam gasped in a lungful of air as I did, the demon distracted by the intense pain that was now throbbing in its neck.

It hurled Madison into the wall, breaking the plaster. I'm going to kill you. The dark voice said, deadly quiet for once. Sam raised his hand towards Madison and began to clench his fist; Madison's eyes grew wide with pain. A soft crunching sound could be heard, and then she fell to the ground as a limp bag of bones. Blood trickled from her mouth, which caused Sam to begin shaking.

Dean stared in shock as Sam's fingernails grew long and sharp, gasping as his brother whirled around to face him. He stared at Sam's now icy blue eyes, vertical slits for irises, and his razor sharp teeth. I'ng going kill you!" He growled, raising his hand slowly to his face. His fist clenched, and a bright light blasted within him. Sam screamed, his back arching towards his clenched fist as light glared from his throat and eyes.

Sam collapsed back to his feet, gasping for breath, as the fist relaxed. It then clenched again, causing the light to explode from within him for a second time. Dean's brother was choking on nothing as he was lifted from the ground, his back arched in pain. You can't…kill me! You're…coming with…wolf! Dean rushed forwards as the demon's voice screamed in pain. Sam relaxed his hand and the light died, sending Sam crashing to the floor. Dean caught him and managed a controlled fall instead of a neck-breaking one.

"Sam. Sammy! Come on bro, wake up!" Dean slapped Sam gently while shaking him, trying to force his brother to wake up. Dean pressed his fingers to Sam's pulse point and breathed a sigh of relief when he caught a weak flutter. Dean grabbed his brother into a hug, awkward because of the younger man's position on the floor. "Aw man, Sammy! You had me worried that you wouldn't make it! Now you just have to wake up bud. Okay? Sammy, can you wake up for me?" Dean was never beyond pleading when it came to his brother.

Dean looked over Sam's battered body while he waited for the boy to reawaken. He noticed that the dark web of veins, that had littered his brother before, was now gone; the black faded back into dim blue with the removal of the demon. Dean wondered briefly how the demon had entered his brother in the first place.

Sam coughed lightly and opened his eyes, blurrily taking in the sight of his older brother cradling him in his arms. "Hey…De." He muttered quietly, his voice sounding like he hadn't spoken in weeks.

"Sam! You're up dude! Want to tell…" Dean trailed off as Sam's eyes opened the rest of the way, revealing shockingly pale blue irises with a vertical slid for a pupil. "Sammy, what is up? I thought that the demon killed the werewolf when it died?!"

"I dunno…Dean. I think that…it only killed the werewolf's mind. I can still hear…your blood pumping and…it sounds good. But it is like not eating candy, instead of a mindless hunger that overrules everything." Sam's voice grew steadily stronger as he spoke; realizing that what he was saying was true. He wanted to eat Dean, but it was in the way that a kid wants to eat Halloween candy; it looks really good, but it's resistible. He then noticed that Dean's and his were the only heartbeats in the room. He squirmed in his brothers arms until he could look behind him, to the broken form lying on the ground.

Before Sam could tell what he was doing, he was flying across the room to Madison, having forgotten entirely about Dean. She flipped face-up without Sam touching her, and his hands ghosted across her still body. He rested his hand above her heart, listening and feeling for any signs of life. He keened a high wail, a howl, as he accepted that she was dead, the death of his mate hitting his chest like a wrecking ball. The werewolf inside was dead, but his instincts were still there; he knew that Madison would have been the perfect mate, the perfect person for his supernatural life.

Dean opened his eyes to see Sam kneeling in front of him, his icy blue eyes trained on Dean's neck. "Pulse is good…" he then put a hand over Dean's eye, and then pulled it away after a few seconds. "Pupil response is fine; no concussion." It was then that Sam noticed his brother's watching gaze. "Oh, Dean. You're up. Um…I'm sorry." He said, scratching the back of his head.

"Sam…what just happened?" He asked, rubbing the sore spot on his head. He noticed Sam's glassy eyes and the red rimming them. Then he took in Madison's dead form on the ground, and put two and two together. Sam was dying on the inside; it was time for Dean to do some patching up. "I threw you-"

"You know what?" Dean cut him off. "I don't care." He continued lightly, sitting up slowly. "Are you okay, Sam? If you can walk fine, let's get Bobby down here."

"Dean…What about Mad…Madison? We can't just…leave her here." Dean broke down at the sight of his brother so hurt, not even able to hold up the façade to help him. "Do you want to bury her, or cremate her?" He asked gently, knowing how close Sam was to shattering into a million pieces. Sam took several minutes to clear himself up enough to answer. Dean didn't like the answer though.

"I could have saved her…Dean. If I had managed to use my power before the demon killed her…I could have saved her." Dean sighed as Sam collapsed into him, his heart-wrenching sobs wracking his entire body. "Sam…" Dean started, but he didn't know what to say. What do you say to someone who had the power to stop themselves from killing their loved one, but couldn't access that power until they were already dead? He just wrapped his arms tightly around his little brother, and let him cry.

Sam finally dried himself out, and he pulled back slowly. Dean kept contact with his arm though, knowing that Sam was never okay enough to be physically alone, on any level, after a huge crying jag like that. "We'll cremate her. I don't want any demons possessing her dead body." Dean nodded solemnly, standing up to help Sam to his feet. He started towards Madison's body, when it lifted itself off the ground. He turned to see Sam with his hand raised, and then he flipped it and beckoned towards himself. Madison's body floated quickly over to Sam, folding itself into his arms. "I'm never going to get used to that." Dean muttered to himself as he followed Sam out the door.

It was still dark by the time they had built up the funeral pyre, Sam using his new psychic powers to gather all the wood quickly. Sam said his final words to Madison, wishing her well in Heaven. He froze as he said the last part though, and turned to Dean. "Dean…what if she doesn't make it. To Heaven, I mean." Dean paused to think, trying to find a good answer for Sam about what happens to a werewolf. He had never thought about it before, always taking it as black and white; werewolves kill people, so they are evil. What if it isn't the werewolf's fault though, like Madison? What if they don't know what they're doing, and are willing to try to stop? Dean hated shades of grey, but he would have to learn to live with them. After all, his Sammy was a super-powered freak, but he wasn't evil. Dean could never kill his brother, for anything; he would always find a way to save him.

He thought long and hard about his answer, hoping that it would put Sam's mind to rest. "Sam, I think that she'll be fine. She may have been a werewolf, and a killer, but it wasn't a conscious decision. I think that, because she was willing to try to stop herself, and because she wasn't even conscious for the murders, that she can't be held responsible for committing them. And the werewolf thing, well…That's not her fault either. She didn't ask the guy to bite her.

"Sam, I am no judge, but she helped to save your life. If I were in charge, that right there would put her above anyone who hadn't saved another, regardless of what they had done in the past. I am positive that she'll be fine, Sam. She made it to heaven; if she didn't, then we are both so totally screwed." Dean smirked at the last line, causing Sam to chuckle lightly. Good, it worked. He thought, smiling at his brother's smile. "Thanks, Dean."

"Hey, no chick-flick moments." He replied, turning to walk away. His phone rang, and Bobby's voice came out from the other end. Sam listened to their conversation for several seconds before Dean noticed and asked, "Sam, can you hear what he's saying?" Sam nodded. Dean explained it to Bobby, who then began talking about how they should come straight to his house. Dean hung up and turned to Sam. "Alright, Snoopy. Let's get you to Charlie Brown's house so that he can check you out. I doubt that Bobby has ever dealt with a psychic werewolf before. This should be fun." Sam rolled his eyes at the heavy sarcasm in Dean's voice, turning to follow his brother into the night.

Hey, so let me know what everyone thought. Please review, I swear I'll reply. Love it, hate it?

BTW, I have two more stories up. Go check out my profile to see them. They're both supernatural, but one of them's a crossover with Twilight. I would love some input from that story, as that is the main one I'm working on right now. please go check em out!
