A/N: This is a story that has been running through my head for the past couple months. I started writing it in April or May and haven't touched on it very much since then for too many reasons that I am so not getting into right now. Anyways… I have been reading a lot of Supernatural fan fics lately, specifically serial killer AUs. Those just fascinate me for some odd reason. Just one more thing to add to the long list of problems I have. So this is going to be one of those serial killer AUs. I can't promise a regularly scheduled update, not like a normally do, because I plan on focusing more on Money Doesn't Buy Dignity, Together, and another new fic I'm writing. Thought I'd let y'all know and I hope you enjoy.

Disclaimer: I do not own anything Supernatural related, except whatever OC I place in the story,

Cats and Mouse

Prologue

She ran down the dark, deserted street; the only audible sound over the rain that continuously beat down hard on her was her heavy panting and wet, sloshy footsteps that she couldn't distinguish from her own or his, though the rain was more of an ice/snow mix, and covered the ground and street. She had no shoes on, so that might have narrowed down who the sounds were coming from.

The rain also made it seemingly impossible for her to tell how close or far away those running footsteps really were from her. She was afraid to look back to check, thinking that if she kept straight ahead, the more distance she could mentally put between them. He shouldn't have been close due to the trap she set for him a while back. She had been running for so long, or maybe it wasn't very long at all. She didn't know anymore. Though she did know she couldn't keep running for very much longer. With no shoes and barely any energy, she would have to find some place to hide, and soon.

A full grown, more like overgrown, athletic, extremely well built man like him would definitely catch up with her eventually. Especially with how tired she was getting. But being chased by him was way better than being chased by the other one who he was with.

He might not have been as big as the one currently chasing her, but he was quicker and more agile. If he had been the one chasing her from the jump, he would have definitely caught up with her by now. Point was, she needed to find somewhere to hide, and fast.

She turned a corner and slid on some of the sludge and ice on the sidewalk, letting out a quick, startled cry. Catching herself on her hands before she face planted into the muddy, icy, polluted concoction, she groaned in frustration as her body shook from the cold and sudden weight and pressure shift from her feet to her hands. She carefully shifted back from her hands to the balls of her feet, remaining in a crouched position. She inspected her hands and saw various cuts, some of which were bleeding slightly.

One more injury to add to the ever growing amount littering her body. She looked around at her surroundings again for anywhere she could hide, knowing that her body had had enough and needed to break, even if only for a moment. She spotted an alley just ahead of her, just on the right, and figured that she could run through and over to the next street and hopefully flag someone down. She hadn't seen anyone on the street she was on the whole time she had been running. She figured it was the part of town that closed up and was vacant of any people the same time every night.

She didn't waste any more time as she shot up and headed straight for the opening between the two buildings, but froze when she saw it was a dead end. The only thing there was a trash bin up against the wall furthest from her. It must have belonged to the building next door, seeing as though the only foot in the alley was right next to it. She knew the place was closed and that no one was there even though the street light above the door was on, so there was no use in wasting time and energy banging on the door.

There were also boxes directly in front of the door that were probably left there by some homeless guy. None of the things there were of any use to her and she knew she couldn't go any further. The chances of getting caught were too high. Not to mention the fact that whatever drugs they had injected into her system before she got away were slowly beginning to take their effect.

The trash bin up against the far wall began to blur in and out of focus and spin, causing vertigo to take her over. She stumbled to the side in her daze, and ended up stepping on a broken beer bottle, a large shard of glass lodging itself deep into her foot.

She bit her lip, to the point where the bitter, irony tang of blood slid across her tongue, in order to suppress a pained cry that wanted so desperately to worm its way past her lips. The fact that she had no idea where the giant man was made her more adamant at keeping quiet.

When she almost fell back into the wall closest to herm she didn't feel the rough, scratchy sensation of the brick buildings surrounding her. Instead, what she felt was cold, hard metal bars pressing into her back. The girl turned and realized she had fallen into a set of stairs leading up to a fire escape. She hadn't even seen the metal contraption when she ran into the small space, being so out of it when she did.

Her observation skills were still honed in on his footsteps, which were not far from her when she concentrated. At this, she didn't waste another second as she completely turned around and began her ascent up the metal ladder. She tried not to make an effort out of using her right foot, not wanting to lodge the glass any further in than it already was. The pain was phenomenal, but her will to survive was stronger than her need to rest, effectively numbing the pain to something bearable.

Once she arrived at the height of the metal contraception, she pulled the ladder up as high as it would go and slip underneath the safety rail and crawled into the farthest, darkest corner underneath a windowsill.

She attempted to open the window, but it appeared to have been locked. There was a hole in the glass in the corner closest to her where it looked like someone tried to break in, or out, and she stuck her hand through to the bend of her elbow, but the window was too wide and her arm couldn't reach the latch in the center. When she tried to pull her arm out, she realized that her plan wasn't very smart because as she struggled to get it out, the glass began to dig into her skin, so when her arm was all the way out, there was a long, gaping cut going up her forearm down to her wrist.

She clutched it to her arm to herself, trying to stop the bleeding as much as she could, and realized a few moments later that her slight misfortune was actually a blessing because the man chose that moment to turn the corner into the alleyway.

He stepped farther into the space until he was standing directly underneath the fire escape. The girl put the hand not covered in blood over her mouth to keep her panting and whimpers unheard.

The tall man had a gun in his hands that he would periodically squeeze the handle of, almost like a nervous tick. He walked over to the only door in the alley and jiggled the handle, soon realizing the place was closed and locked up tight, much like the girl assumed it was.

He went over to the trash bin, inspecting it to see if she had climbed inside. He was quick to open the lid, and groaned in disgust at the repulsive odor emitting from the bins contents. Rats, maggots, and roaches squirmed their way through any organic materials and the girl would have hurled at the sight if she wasn't sure the man below would find her.

There was a sudden warm, wet sensation on her left foot. She brushed it off as just rain or blood from her right foot, until it began to scurry farther up her leg, causing her to cry out and fling whatever it was into the boxes below. That caught the man's attention as he turned around to lock back to the rest of the alley and back out to the street. His eyes were calculative and searching; his breathing mute to his own ears as he tried to locate the source of the sound.

He walked back under the fire escape and over to the boxes. Crouching down, he looked over the wet, soggy cardboard before they moved and he pulled them aside and five rats ran out and past him, the movement not seeming to faze him in the slightest.

He was about to stand back up and walk out of the alley, before a little red speck caught his attention. The closer he looked, the more of them there were. He dabbed his index and middle fingers in a particularly large puddle and brought them closer into the light of his flashlight in order to better inspect.

The girl had to squeeze her eyes shut when the man brought his blood stained fingers to his lips, his tongue slipping past to lick up the crimson liquid. He pushed the fingers farther into his mouth and his eyes seemed to slide closed on their own accord as he let out a euphoric moan of pleasure. She thought she was going to be sick when he repeated the action by gathering more of the blood that had fallen down from her injuries.

"Sammy," a voice called from the mouth of the alley. When the girl looked up from her foot, she saw the other man who had been working with the one below her.

"Mm," he moaned a final time as he pulled his fingers out of his mouth in order to speak. "This is her blood Dean, I'd know it anywhere. She's hurt, but I don't know where she is," Sammy groaned, a mix between pain and ecstasy. "I need more D."

Dean walked farther into the small space until he was standing directly above Sammy and directly beneath the girl.

"I know little brother, and we'll find her. In the meantime, I need to get you out of this rain before you catch pneumonia. My job to watch after you. Come on," Dean helped Sam up and out of the alley to the onyx black car parked directly in front of the entrance.

Both men got in the car–Sam still had a blissed out look on his face, his mouth slightly agape as his eyes, pupils dilated to the point where his hazel irises were almost nonexistent, ran over the small, disgusting hole between the two buildings, searching once more for his prey –and drove away, the roar of the car's engine fading out the farther away they drove.

The girl let out a noise that was a mix between a sigh and a chocked off sob. She was so close to being caught, and she knew that if they did see her, she wouldn't have had the energy to fight or run. Now, she might actually live to see sunrise. That is, if she didn't bleed to death first.

She cautiously made her way back down the fire escape after having to try numerous times to get the thing to go back down, her hands barely holding on due to the bars being frigid and slippery. She noticed that is wasn't only frozen water and ice, because ice wasn't red.

Between the gash in her foot, on her arm, and all the other cuts and incisions the men, brothers, inflicted upon her body, she was losing more blood than previously anticipated. She was losing enough to get on the ladder and the ground beneath it.

It had already seeped through the once pure white dress that clung to her body, something the two men had put her in, the other one saying that she reminded him of someone he once knew who looked beautiful in white. The liquid covered her arms legs, smeared there from when she had fallen into the wall and huddled underneath the windowsill in order to be as small as possible to not be seen by either brother, holding her arm close to her body to try and stop the bleeding.

Now when she swayed from dizziness, she was unsure whether it was from the drugs in her system or blood loss. Did the drugs even work now that she had lost so much blood?

She stumbled towards the mouth of the alleyway, knowing that if she were to stop or fall she would not be able to get back up. She needed to keep going.

Soon, the sidewalk came back into view and she could see the traffic light at the corner, continuing on from green to yellow to red even though there were no cars coming from either direction.

Her legs were beginning to wobble and shake beneath her with every step she took, to the point where they could no longer support her at all. She fell to the ground and lie on her side, unable to stand or even think about standing, as she thought she wouldn't be.

She never figured she would die like this, but then again, who imagines how they will one day die? No one knows and things happen every day that make you question how it will all end for you when your time comes.

She tried to keep her eyes open for as long as she could, though her body protested, only wanting her to give in and let unconsciousness claim her as its own.

But something caught her attention, keeping her awake, even if only for a little while longer. It was a voice, a man's voice, and at first she thought it was one of the brothers coming back for her. The thought alone made her struggle to get up so she could run again with energy she didn't have, and her limbs proved that as they would not cooperate with the message her brain was attempting to send. She was just too tired.

But the closer the voice got to her, the more worried it sounded. It was gruff, but not as deep and commanding as the brothers. There was also a bright white light shining in her face, which was turned in the direction both voices were coming from. The light hurt her eyes and all she wanted was for the man to go away and take the light with him.

"No no, darlin'. You need to stay awake." The man's voice spoke softly to her. "Ellen, help me get her into the back."

It wasn't until a woman came into view that the girl realized she was even there. Her face was worried, but the girl thought she was beautiful with her long brown hair and warm eyes. Though the girl was slightly freaked out when the two came closer to her, the warmth in the woman's eyes told her she was safe.

"Get her other side," The man said.

"I got her." The woman, Ellen, replied as the two lifted the girl off the ground. Ellen's voice was comforting to the girl as well. It lulled her into unconsciousness once she was placed down on a soft surface.

The last thing the girl heard before the blessed darkness consumed her was the panicked voices of her saviors.

A/N: Like I said up top, I am working on a couple of things right now, so don't get upset if the posts for this are infrequent. Though this is something that I think is going to be fun because Supernatural serial killer AUs are getting to me right now. I just love them. I'm already working on the next part, so we'll see when this is updated. OK, so R&R. I really want to know what y'all think, as always. Thanks all!
