Set during season 9. During a hunt, the boys meet a mysterious woman who cannot remember who she is or where she is from, but can hunt like a Winchester. It becomes clear that this woman could be the key to re-storing not only heaven but heavens most wanted angel as well. not the best description, but give the story a chance… my first supernatural fanfic. Also random note but I'm British so some Americanisms I will more than likely either miss or get wrong. Eventual Castiel/OC Read and Review. :)

Thick, thunderous rain beat down on the hood of the Impala as it tore through the derelict streets of a seemingly abandoned town, Dean and Sam had been tracking a single vampire through the countryside of Pierce County for the past week and finally had a solid lead on where the creature would be landing next. They had been taking some time out from angels and demons whilst Sam recovered from his ordeal with Gadriel and found a relatively bog standard case of vampirism that was sure to put the spring back in their step, or at least the drown their sorrows in the local bars.

"so, go over this one more time. That kid, the one from the skatepark, he's the fang?" Dean's brow knit together as he squinted through the lashings of water pouring down his windshield, visibility was shocking, but Dean figured that in a town like this there ain't much traffic after midnight.

"Yeah, in a town with a dwindling population, it almost looks like he's wiped out half, if not all of what was left" Sam sighed as he poured over his notes, his body still ached and he knew he wasn't 100%, but sitting at home watching crappy TV and choking down whatever fast food Dean could find that day, was not the answer. Hunting was the only medicine Sam ever knew, the only way to fix yourself was to save someone else, and so tonight, that was the Impala rumbled to a halt in front of an old ranch at the bottom of a long dirt track, a dark empty shack stood before them, barely held together but clinging to itself like a rotten carcass held together by ribbons of flesh. Wooden planks nailed to each other, a door swinging on one hinge, softly creaked in the night air, but even with that, the silence was foreboding. The rain had eased to a soft drizzle, puddles squelching under boot as Sam and Dean cautiously moved towards the shack, their guns in hand, cocked and had heard that this was the Vampire's nest, a single vampire was becoming the norm of late with many nests being destroyed during the reign of the Leviathan, and this one was setting up shop in rural towns and turning its inhabitants or simply feasting. Dean approached the door and pushed it to one side, immediately it fell off its final hinge and into Dean's arms. Shoving it to one side, Dean motioned for Sam to follow behind as he stepped over the threshold and walked through the decaying jaws of the shack, the walls oozed with mould, the wallpaper was sagged and torn creating piles of sludge on the floors where it had come to rest. Sam covered his nose, unable to stomach the putrid stench of rot and death that hung in the air.

"I think several somethings died here and it wasn't recent neither" Dean spoke on an inbreath, daring not to take his hand away from his face for too long. Sam nodded in agreement as they picked up the pace and searchd the empty hall and into what would have been the family room. Vintage furniture which once held value, was now strewn across the floor, marred, decayed and vandalised. This place had been many things in its time, a working ranch, a family home, a teenagers hide-out and now the nest of a vicious monster. It was time this old place be put to rest, along with whatever lurked in it's shadows. The glint of a faint light caught Sam's attention as he worked his way through the mess towards a door at the back of the room, it's frame glowed with promise as the boys each took a side and gave the nod, kicking it from it's hinges and bursting into the light.

The empty room glowed from the light of a single candle lit on a wooden table. "What the hell" Dean grumbled as he tore through the room, looking for a clue or even something to take his growing fury out on. "Is this a freaking joke?" he shouted as Sam searched the walls for a sigil or secret passage. He examined the candle on the table, measuring and calculating in his head before turning to Dean."This candle cannot have been lit for more than an hour or two at most" He pointed to the wick, still relatively fresh. "There is barely any wax collecting at the bottom, he must be here Dean, he must be somewhere in this place" Sam holstered his gun and looked above his head, placing a finger to his lips and pointing for Dean to look up. Faint footsteps padded above them, soft floorboards creaked and moaned under the weight of a hidden body. Sam breezed carefully through the lower ground of the shack and towards what was left of its stairs, many of which were missing leaving gaping black death traps as he dodged and weaved to it's higher level, as Sam reached the final step the stairs gave its final groan and crumbled to a heap, leaving Dean stranded below. "Sam!" he whispered "You go ahead, I'll try and find another way up! Just be careful" he warned before turning on his heel and rushing back through the old family room.

Sam stepped carefully onto the second floor, wary of not baring too much weight down on any one floorboard, just incase. The second floor had been more protected from the elements with some of the glass still remaining in windows, however nature had still tried to reclaim much of it's walls and floors. Thick cobweb still clung where it could and the dust was whipping through the air with every step that Sam took, he re-covered his mouth and nose, protecting his lungs from the dirt. The footsteps had ceased but he had remembered them coming from above the back room and so carefully he moved towards the door upstairs, reaching out he pushed through a veil of cobwebs and into a room. He had barely made it four steps before he felt a crushing weight throw him to the floor and felt his shoulder connect with the wood making an awful crunch. He rolled to his side just as a knife streaked through the air and into the wood where he had been laying. Still attempting to wipe the dirt and cobweb from his face, he clumsily threw a punch into the air but missed his target, feeling a boot connect with his stomach as he attempted to stand. With one final wipe he pulled the last of the dirt from his eyes to see his attacker.

A young woman stood before him, one of her brown boots pushing into his stomach and her piercing green eyes boring into his soul. "say goodnight you bloodsucking maggot' She hissed as she raised a large knife above her head, ready to bring down on Sam's throat. Sam tensed and pushed her boot off just as the knife came down, sending her tumbling to one side and her knife clattering across the floor to the opposite side of the room. Sam grunted as he clutched his injured shoulder and pulled himself to stand, grabbing his gun and aiming at the slight woman who now stood opposite him, brandishing her own pistol. "who are you?" Sam demanded, waving his gun in her direction. The woman looked Sam up and down, her features illuminated by the light from the upstairs windows. Sam figured she could not have been more than 30, her skin was dirty with grazes and small cuts dotted across her jaw and cheek presumably from their tussle. Her blonde hair, covered in muck and cobweb, had been pulled into a thick matted bun on top of her head and she wore simple combat trousers and a white vest which clearly were too big. Her green eyes glittered despite the large dark circles which surrounded them, and her lips were thin and pain tightened, she appeared as though she had not slept for days. "Are you okay?" Sam asked, concern gripping him. This was no vampire, this was a human, and a human in danger at that.

"What?" the woman asked, her mind fogged with fatigue and confusion. It had become clear to her now that this was no vampire, vampires would certainly not ask her about her welfare, and more than that, she was bleeding and no vampire would be able to stand and have a conversation with her without practically foaming at the mouth. "You're not a vampire, then what the hell are you?" she asked.

"I'm a… Sam Winchester. I'm a hunter" Sam tried to explain, he holstered his gun in an attempt to show solidarity."I won't hurt you" he held his hands above his head."Please just tell me your name" Sam tried.

The woman held her gun steadily pointed at Sam, she had not had the pleasure of many cordial meetings in the last few months and still found the idea of somebody being kind to her, off-putting at best. "I'm Eva" she started, unable to share any more information than that. "I don't know what I am" she choked out. Eva had no idea why she was telling this strange man this, but it was true, Eva could only remember the last 6 months of her life waking one morning in a field in the middle of campground and not understanding how she had got there. The only thing she had was a sleeping bag with a name sewn into it, 'Eva' ,and so that is what she decided she was called. There had been nobody to ask and nobody to tell and so she had began trekking her way across the country looking for answers, but so far all she had found was more questions, and monsters, so many monsters. The first time she had killed one had been on accident, it had been a wendigo out in the forest where she had been camping, but after, she felt as though she had found some purpose and had gone on to research the supernatural from case to case, hoping that one day somewhere along the craziness she would remember her old life and who the hell she was.

She had tried to explain this as best she could to the stranger, Sam, but couldn't bring herself to lower her gun, expecting at any moment he would rush her and spray a million bullets into her. She couldn't explain this fear that seemed to grip her constantly, but the man simply smiled at her. "I'm sorry to hear that Eva. How long have you been hunting this vampire" he asked softly.

about a month" Eva explained. "I tracked him all the here from 30 miles away, snook in upstairs and was waiting for him to come back up here when you came in" she assessed Sam and the injuries she had inflicted, he had a busted lip and was still clutching his shoulder. "sorry about that" she smiled weakly. "I kind of shoot first, ask questions later

"Yeah, I know the kind, me and my brother we-"Sam started before the realisation hit him. "did you say come back? Where is the vamp now Eva?" Sam's eyes widened.

"Downstairs".

Dean clambered over the old furniture and shoved his way past an old display cabinet as he forced his way into the kitchen, looking for a way to climb to the second floor to help his brother, hell, even a ladder would do at this point. Dean pulled a large cabinet and searched, unaware of the figure looming in the shadows, approaching silently from behind.

"Damn place is condemned" He grumbled aloud, throwing the rusty cabinet door to one side.

""Sorry" The voice chimed in from behind "I didn't get a chance to clean up" it sneered.

Dean whirled around quickly to find himself face to face with what looked to be a teenaged boy, his face inches from his own, he could smell the blood on his breath.

"I've been wondering how long it would take you to find me, Dean Winchester" the goading voice spoke. "I know there is another of your little friends upstairs as well, I was saving her as a little treat, an after dinner snack you might say" he laughed

"Yeah well, dinner time is over you filth" Dean launched himself towards the vampire with his knife ready to slice, but the vampire was quick to grab at his arm and slap the knife across the room, whirling dean around and leaning down to take a long smell of his neck.

""I can hear your pulse, I can smell your blood, I've been so excited for this moment Dean" The vampire opened his mouth to reveal rows of sharp teeth and was about to plunge them into Dean's neck. Dean gripped the vampire's arm, dragging him down with all his weight. Just as Dean felt the teeth begin to pierce his skin a large crash sounded from above and two bodies smashed through the flooring from above and straight down in front of Dean.

"ding dong" Eva grinned as she jumped up and charged at the vampire who had raised his neck from his feast on Dean. Dean toppled to one side and Sam rushed to his aid, checking he was alive. Meanwhile Eva wrestled with the vampire on the floor, punching at the creature before raising her knife one more time and bringing it straight down on the vamp's neck, severing his head from his body. Eva could feel the room spinning, she had taken far too many tumbles in the space of an hour and this job had really taken its toll on her. She rolled away from the mangled remains of the vampire and attempted to stand, she could see the two men ahead of her through blurred vision but as she reached out towards them, all went black.

"Er Sam" Dean looked to his brother as he stared at the unconscious body of the strange woman on the floor. "Whose the chick? he asked.

Sam combed his fingers through his air and smiled "I have absolutely no idea, but er, I think she's one of us now"
