Hey there everybody. I'm a new writer to this site, this is my first story posted here and my first ever Supernatural fanfiction. I'm hoping like hell that people do read this and enjoy it, because I've been working super hard on this and love it so far!

DISCLAIMER: I do not own the characters of Supernatural. That means Sam, Dean, Bobby Singer or any other characters from the TV show are not my own, and I am merely using them for creative purposes. I have added two original female characters to counter with the Winchester boys, and these characters are totally original, along with the plot line, etc.

Anyway, if you read this, could you please leave a comment/review or something just so that I know someone is reading it and will therefore feel motivated to post. God, I'm super nervous here. Hope you people enjoy.

CHAPTER ONE.

Black.

It was the first word that registered in Kieryn's mind as she awoke. Everything was black. She rubbed at her eyes with closed fists, etching them open again as specks of light began to filter in through the small gaps between her squinted lids. The white luminance came in small, blurred circles, repeated in a long line above her, as far as her eye could see. Through the black that surrounded them, the lights shone out as though they were reaching for her, beckoning for her to follow.

Yet she couldn't move, could only watch as the lights danced above her in the black of the night, now as though they were taunting her, laughing at her.

A loud screech in the distance broke the silence that was engulfing her, awakening her senses along with it. Towards her sped two more specks of white light, growing larger and larger in diameter as they approached with incredulous speed. She could hear the revving of a car's engine, the protesting squeals of tyres along the tarseal road, the sounds growing louder with each prolonged moment until she knew it was too late.

Kieryn ducked her head in that instant, screwing her eyes closed and rocking herself forwards, bracing herself for the inevitable blow as the car would soon hit her side.

"STOP!" Sam screamed over the pulsing music, instinctively reaching over his elder brother in the drivers seat and yanking the steering wheel towards him. The car fled to the right immediately and Dean managed to slam the brake pedal downward before the hood of the car hit one of the tall lampposts lining the pathway. Dean turned the keys in the ignition hastily, causing to car engine to judder to a halt.

"What the hell, Sam?" He chided, gaping at his younger brother in the passenger seat who was hurrying to unclip his seat belt.

Sam merely ignored his brother's interrogating glare, flinging the car door open and racing over to the small frame that remained motionless in the centre of the road. Once he was within a metre of the figure, his pace slowed to a vigilant stroll and he crouched over onto one knee in front of it. He was certain now that it was a young woman, judging by the slenderness of her hunched over body and the straight, dark wisps of hair that shied her face from his view.

"Are you alright?" He asked cautiously, his voice soft and assuring so as not to alarm the girl with his sudden presence. He heard her jagged breathing slow to a more natural, consistent pace and waited as her head etched up, the girl's long strands of hair falling away from her face one by one until her widened eyes met with Sam's in a fearful glance.

Kieryn watched the man in front of her hesitantly, her bloodshot eyes widened with the innocence she possessed and the fear that was filing it's way into her brain. The man was tall, she knew that even despite the fact that he was crouched over. He was definitely young, too, for no lines creviced his handsome face. A chocolate brown mop of hair laid upon his head, his bangs falling into his eyes the slightest.

The sound of boots scuffing against the darkened pavement caused her gaze to falter from the man before her to the source of the interruption, her eyes falling upon another man who was approaching from behind the first man. His piercing gaze was fixed upon Kieryn as though he sensed that any second she may disappear right before him.

"Possessed?" Dean asked almost inaudibly as he etched closer to his younger brother, making sure to maintain his gaze locked upon the stranger in front of them. Dean knew from experience that though she looked totally innocent, she could be anything but that. He didn't want to go welcoming her with open arms only to have this whole meeting turn out to be a trap, or even just a nasty coincidence. Dean didn't run risks like that.

Sam shook his head, "I don't think so," he muttered, uncoiling his arm, stretching it out in front of himself toward the girl. Dean instinctively rushed forward, kicking his brother's arm away from the stranger rashly, gripping his gun in his back pocket.

"Christo." Dean uttered, and when the girl's blank expression turned to obvious confusion he sighed, but remained with his hand clutching his silver 45 behind his back.

Sam reached out once more, taking the girl's hand in his own and helping her stand shakily. From what he could see she didn't have any trouble with standing, giving him the relieving impression that she wasn't injured, only frightened.

"What's your name?" Dean demanded, not bothering to hide his lack of trust in the stranger. Trust had already nearly gotten he and his brother killed on numerous occasions and he wasn't willing to let that happen again. His grip on the gun handle tightened.

"Kieryn." She muttered, giving the second man a quick once over to accompany her reply. He was shorter than the other man, but of a larger build, his shoulders tensed wearily, his arm clutching something unknown to her behind his back. His short, sandy hair was spiked to a point and he wore a staunch, unyielding expression upon his face.

"Well, Kieryn, I'm Dean and this is my brother, Sam. Nice to meet you, but we've got to be off." With those words spoken, Dean grabbed his brother by the collar of his brown jacket, proceeding to lead him back toward the sleek black car parked on the footpath.

"Dean!" Sam shook away from the elder siblings hold, "we can't just leave her here!" Shoving past his brother, Sam beckoned to Kieryn, a reassuring smile fashioning his face. "Come on. We'll take you home."

Kieryn hesitated at first, wondering whether or not to trust the strange men who had discovered her. Kieryn lived in a small town, one where everybody knew each other and no one went unnoticed; but Kieryn was certain she'd never seen either of these men in her life.

Despite her brain telling her to run, far away, Kieryn followed the first man, whom to her new knowledge went by the name Sam. But once she stepped into the glaring blaze of a streetlamp's light stream, Sam let out a gasp, staggering away from her as though she had just shape shifted before him. Which she hadn't, of course. That was absurd.

Dean pushed his brother to the side immediately, snapped his 45 from his back pocket and aimed it at the girl, all in the matter of a second.

"You can't shoot her, Dean." Sam muttered urgently from behind him, "she could be innocent. We need to talk to her."

Kieryn stared at the barrel of the gun, only just registering that it was pointed directly toward her. Her heartbeat began to accelerate as she glanced down at her attire. Her breath hitched in her throat at the sight of the bloodied clothing that clung to her body, the dark red stains unmistakeable against the light grey of her singlet.

She looked back up at the two men frantically, scrambling to form words upon her lips, though no sound left her mouth. "I didn't-I-" She stuttered across the words, though no audible explanation followed them. "My… sister," she said finally, simply, "I need to find her."

Sam exchanged a weary glance with his brother, mentally arguing with him through merely the assertive look in his eye, before he reached out and grabbed Kieryn's arm, gently leading her toward Dean's Impala.

"Where do you live?" Sam asked once they were all seated inside the car, shooting a glance in the rear view mirror to catch a small glimpse of the girl seated silently in the back seat. She looked totally traumatized, her dark eyes upholding a blank, terrified gloom to them, surrounded in dark circles that seemed dug into the flesh of her pale face. He noticed now, in the blaze of the car's interior lighting, that her hair was a shade of natural auburn brown, tinged orange, reaching a few centre metres past her shoulders in straight wisps

"18 Salisbury Road." She replied quietly, letting her eyelids fall closed as her head rested back against the car's black leather interior. She was exhausted and cold, but for the most part, confused. The last thing she remembered was getting into bed at 9:30pm, and now here she was, in a car with two complete strangers, with no clue to how she ended up on the middle of that strange road in the first place.

Not to mention she was covered head to toe in someone else's blood.

Kieryn refused to let the idea that she had hurt someone enter her head. There had to be a reasonable explanation for all of this. Now she just needed to find out what that explanation was, so that she would never have to think about this night again. But before she could do that, she had to get home to her sister.

"You think she's responsible for the murders?" Dean hissed, sending his brother a sideways glance before refocusing his gaze on the road ahead.

"I don't know." Sam mumbled, truthfully, "she doesn't exactly look the type," with this he stole another glance in the rear view mirror, noticing her lids were now tightly closed and a content smile graced her lips. Sam couldn't at all picture such an innocent face yielding the capability of taking the life of another. She couldn't have been any older than 22, Sam concluded, after studying her calm face in the mirror for a few extra moments. "You thinking what I'm thinking?"

"I think I am, B2!" Dean grinned sarcastically, causing Sam to sigh in annoyance at his brother's immaturity during a serious matter.

"We need to find out where all that blood came from." He stated, deciding to ignore his brother's last remark.

"Talking to the witness would be a good start," Dean mused, making sure to speak quietly so as not to let their new companion overhear.

"Yeah," Sam agreed, though the uncertainty he held shone through with the word. "But first, I think we ought to go back to where we found her. See if we can pick up any trails."

Dean nodded slowly, processing through Sam's method. "Good plan. We'll check that out tonight, then question her in the morning," Dean beckoned behind him with a backward nod of his head, "I don't think we'd get much out of her tonight." With those words, Sam's gaze flicked back up to the rear view mirror to see the girl seemingly sound asleep, her mouth agape the slightest, her legs pulled up to her chest with her chin resting between her knees.

Dean's car swerved to the right to park along the curb outside a small, suburban looking home. It was a grand, double story house with white horizontal panelling running the entire length of the front walls, glowing an eerie yellow from the glare of a streetlight lining the curb.

Sam slid out of the passenger side, etching open Kieryn's door and hesitating before deciding against waking her. She appeared so peaceful in her sleep, and Sam didn't want to be the one to deprive her of that peace. He carefully reached over the petite girl, unlatching her seatbelt before scooping her limp frame into his arms.

Dean had already rung the doorbell by the time Sam made it up the short pathway to the front porch, where the front door was already being pulled ajar.

"This belong to you?" Sam asked with a small smile, watching as Kieryn's eyes flickered open and a look of sheer confusion crossed her features. Sam set her down on the ground hurriedly, crossing his arms over one another.

The girl in the doorway had wavy, honey blonde hair, a petite figure and stood a few centre metres taller than Kieryn. She appeared to be the older of the two, icy blues eyes possessing an air of maturity and knowledge her sister's did not. "Oh, thank God!" The girl behind the door exclaimed, wrapping her arms around Kieryn's small frame. A weary smile crept onto her face as she examined the two men before her over her sister's shoulder.

Dean smirked, raising his eyebrows, "actually, just call me-"

"Dean." Sam warned through clenched teeth, punching his brother in the shoulder roughly. Anyone could have easily mistaken the hit as a playful gesture, but Dean, being on the receiving end, felt the full force of Sam's punch and therefore knew the real intensity behind it.

Dean scowled, glaring at his brother for cutting his witty remark short.

The two girls pulled away from each other and a look of pure horror formed upon the older girl's features as she noticed for the first time the state of Kieryn's bloodied clothing. "Get inside." She mumbled, to her sister's ears only, and Kieryn obliged, sending Sam and Dean a small smile and an abrupt head nod before disappearing inside the house.

"I'm Sam." Sam introduced himself, ignoring the odd manner of the sister's reunion. He knew most people should freak out at the sight of their sister covered head to toe in blood, but the blonde remained completely calm. Too calm, for Sam's liking. "Dean," as he said this he beckoned toward Dean, who grinned instantly as the blonde's gaze fell upon him.

She returned the smile, pushing a lock of blonde hair behind her ear, "Emerson. You guys cops or something?"

Sam and Dean exchanged a comical glance before Dean replied, "something like that."

"We'd like to talk to your sister again in the morning, if that's alright." Sam did his best to sound sincere.

Emerson nodded, "of course. Whatever you guys need," with this, a lopsided smile graced her lips as she eyed the two men cautiously.

"Well, that was odd." Sam uttered as he and Dean departed the property.

"Yeah," Dean murmured, "a little too Stepford, don't you think?"

Sam snickered lightly, sliding his tall figure into the passenger seat of his brother's car, "you've used that line before, Dean. It's not funny anymore."

"Damn it." Dean muttered, twisting the keys in the ignition to allow the car to splutter to life, before pulling the car away from the curb and driving back in the direction they had came merely moments before.
