I've had this idea in my head for a while now, and I've only just started to write. This is a flashback, so it's not all going to be like this. Jenny is 14 in this chapter.

1995

Broomfield, Colorado

The rain had been falling for at least a few hours now, heavily, but not so that you couldn't see what was ahead. The whole street was practically deserted apart from the random car that came by rarely and a teenage girl walking quickly in the darkness.

Jennifer – or as she preferred, Jenny – was out past her curfew, and she was going to get in trouble. Not that it bothered her very much, however her foster parents wouldn't take kindly to her being out again late at night. Eleven was hardly late in her opinion. She had done all nighters before easily, but she didn't want to keep it up. She needed to break the habit before she got into real trouble.

Rummaging though the pockets in her jeans as she walked, she looked for her keys, hoping that they would be in bed, and then she could claim she was only a little bit late... or at least not pay attention to the sound of the front door opening. Oh who was she kidding? She was totally screwed this time. She was going to get grounded for sure... and then she wouldn't have fun explaining to Jimmy and Nicole how she couldn't hang out for a while.

Jenny pulled a hand through her soaking hair. Droplets of water fell down the back of her neck making her shiver. She wished she'd bought an umbrella or something. It probably would have made more sense to start walking home before it got too heavy, but her friends really did have a way to keep her out. They promised her a good time, and she'd had one. She really hoped that she wouldn't get in trouble, because the next time Jimmy said he would try and get some more alcohol from his cousin. And Nicole would meet up with Blake to get some more crack cause' their stash was running pretty low.

Jenny knew that what they did was wrong, but she couldn't care enough. She'd met Jimmy and Nicole when her foster parents had made her go to some group to talk about her "feelings". She'd hated it, and so did they. So they snuck out halfway through and decided to have their own group thing. ...Yeah

They were all going to the same high school now, so they could still hang out as often, and it was – in their words – awesome.

Finally getting to the front door, Jenny pushed her hand back through her sleeve that was almost covering all her skin, trying to keep her hand warm from the cold. She pushed the key in the lock and opened the door.

The hallway was in darkness. The whole house seemed to be. There were no lights on upstairs or in the living room either. Kate and Justin – her foster parents – were probably in bed by now. She glanced at the clock which was illuminated because of a street light outside and it was about ten past eleven. Maybe they'd got an early night?

No, there wasn't a reason why they would be in bed that early. It was a Saturday night. They would most likely be watching some evening TV. Something was really off, and she didn't know why or what. It just seemed weird.

Jenny slipped out of her shoes, leaving them by the door. Another habit of her's was not putting her shoes away. Well, there didn't seem to be anyone around to tell her to take them upstairs...

When she walked into the living room, something really didn't seem right. It was too quiet. The TV was on, but it wasn't on any channel. In fact, their cable box was off, leaving the black and white static on the screen. She slowly walked towards it, curiously watching the screen. The time in the corner counting down from five minutes came to the last few seconds and the screen went black, leaving only the reflection of her drowned face in the blank screen.

She reached forwards slowly and pressed the off button, making the red light turn off on the front. Now there was silence.

But not completely.

In the kitchen she could hear a muffled dripping noise - as if the taps in the sink hadn't been screwed back properly. Kate never left the taps like that...

Something was really, really wrong. But Jenny couldn't just ignore it. She had to go in and see what was going on. What was going on?

She stepped through, somehow being possessed to make as little noise as she could. If her foster parents really were asleep and she was just being paranoid she had to make sure she didn't wake them just because she was a little suspicious.

When she got in the kitchen, however, she knew Kate and Justin weren't in their beds.

She stopped breathing. Something wasn't just wrong. It was absolutely horrific. It wasn't the dripping of the sink she had heard. It was the dripping of the blood from the kitchen counters to the floor. A pool of blood trailed down the side. Justin. His eyes were shut and he was facing the ceiling, unmoving. His throat had been slit.

Someone must have forced a window or the back door. But why? They'd left the TV. What about Kate?

Kate. Jenny wiped away the silent tears that had formed on her face. She was not a crier, and she wouldn't make a sound.

She took a steadying breath, trying to get control of herself. She closed her eyes, not wanting to see Justin anymore... how could he just be... gone?

The floorboards creaked upstairs. Jenny's eyes snapped open, wide. Whoever had done it was still there – that was her first thought. Either that or it was Kate. Would Kate be hiding from fear thinking they were still there? Surely she had heard something... Jenny didn't know anything about what had happened, and she knew she needed to go look. But she was scared. Scared about what she would find upstairs... She needed a weapon.

Edging around, trying to stay as far away from Justin as she could, she slipped her hand into the cutlery drawer and silently slipped out a silver knife. They had always had silver cutlery, not that it would make much different. A butter knife. Great. But she couldn't think straight. She just needed to know that she would be able to put up some kind of fight if anyone was still around.

Jenny moved slowly, trying to make as little noise as possible. She was dripping onto the carpet, but she couldn't take her coat off. She couldn't let her guard down. She peeked around each corner downstairs. There was nothing there. The only option now was to go upstairs and check it out.

She got up the stairs and got onto the landing as quietly as she could, holding her breath. Her heart pounded in her chest and she could feel it in her throat, a constant drumming, so fast. She clutched the butter knife in her right hand, holding it by her side so tight her nails dug into her skin as her fingers were wrapped around it.

Bathroom. Empty. Her room. Empty.

Only one room left.

One last room...

Kate.

Jenny held up the knife as terror crossed her face. Kate was lying on the floor with her throat cut open, just like Justin's had been downstairs. A second pool of blood had gathered on the carpet. She couldn't scream, not now. Standing over Kate's body was a girl. A teenage girl.

It was Jenny.

An exact replica of Jenny was standing in the middle of the room holding a knife. The only difference between them was the knives they were holding, and how one looked so unbelievably happy, while the real Jenny was overloading with emotions.

Was this some kind of sick joke?

Real Jenny stood there for a split second. Whatever that thing was, it had to die. Some unknown strength rose up inside her with overwhelming anger and pain. She ran forward, holding up the butter knife, ready to attack whatever that thing was.

Fake Jenny was ready, too. She held her knife forwards, swiping it across real Jenny's arm making her cry out in pain, but she kept going. Fake Jenny tried to get to her throat, holding the knife up to her neck, but Jenny caught her with her other hand and tried to pull her off. Both pairs of identical hands were either trying to attack or defend.

Stepping backwards, real Jenny tried to get away, no longer trying to attack anymore. She just needed to get out of there without dying. But fake Jenny came closer and backed her against the wall.

"You should have seen their faces." She whispered to her as she had her up against the not-so-white wall. "They thought it was you."

Real Jenny stared her in the eyes – her own eyes. Jenny hadn't killed them, but she knew that their last thoughts would have been that it was. The last thing that crossed their minds was how their foster daughter had killed them.

Some daughter she'd turned out to be. She didn't kill them, but she might as well have to Kate and Justin.

Fake Jenny had been too happy to realise that real Jenny had turned the knife around in her hand. The silver knife touched her skin and she cried out in pain, hissing. The butter knife seemed to hurt her just by touching her. Silver was how to hurt it?

Jenny looked down at the knife in her hands. She had the power to end this, now. She ran forwards, ready to strike again and plunged the knife into her stomach. Fake Jenny howled and hissed, placing her hands on her wounds.

"You bitch!" she yelled, holding up her own weapon again.

Real Jenny was faster this time, though, and cut the hand holding the knife making her drop it instantly. Then she pushed her over and she fell backwards. Jenny pushed the butter knife through to her identical heart. She pulled out the knife again and repeated it numerous times. Tears rolled down her cheeks as she kept pulling out the knife and pushing it back in, over and over again.

Fake Jenny died eight stabs ago, but Jenny kept going until the knife slipped through her fingers and she just cried. Jenny wasn't a crier.

Sobbing uncontrollably, she crawled over to Kate's body. She was dead. If Jenny had been there, she might have been able to stop whatever it was before it killed her and Justin. They'd both died... they'd just gone while Jenny was out drinking and laughing with her friends. She wouldn't be able to be with them now... she wouldn't be able to be with them again.

Jenny had to go.

Standing up, she backed out of the room. Her vision, blurry, as she tried to get a grip on herself and find her room down the hall. Money... clothes... valuables. The important stuff she would keep with her. The rest would have to stay. When the authorities got there, she would be announced as dead with Kate and Justin. That's how it was. She would never be able to explain this. Never. She had to get out of there. Leave... run... not looking back.

Jenny stumbled down the stairs, in too much emotional pain to care about the cut on her arm. She could fix that up later. Where would she go?

Running down the street, it was still raining. Lighter now, but still wet. She stepped in a large puddle by accident, soaking one of her feet, but she couldn't care less. She kept turning back, paranoid and scared. When she had been out there only twenty minutes ago she had been worried about getting home. Now, it was getting away that was what was worrying her.

Distantly she heard a voice yelling, but she didn't dare listen. Running. Listening to the pounding of her heart still not slowing. She couldn't stop. She couldn't ever stop...

"JENNY!" the voice yelled again, and she heard it was her name this time. She barely recognised the voice. All she could hear properly was the sound of her heavy breathing.

You should have seen their faces, she remembered. They thought it was you.

A black car. A black car was coming down towards her. She could barely see it over her blurred vision with the rain and her tears.

"JENNY!" the guy in the front yelled at her again.

Jenny was still running. I can't stop! She wanted to yell, but couldn't find her voice, and she was still trying to breathe. The car came up beside her. She knew who it was, and she couldn't be anymore grateful.

She finally slowed, unable to keep running anymore. "Uncle John." She only just managed to say, trying to catch her breath. Her short blonde hair was flat with rain water, a few stray hairs sticking to her cheeks.

"Get in." he ordered, gently, tilting his head towards the back. She could see Dean in the back. She remembered Dean. He watched her, sympathetically as she slowly opened the door and slid into the seat next to him.

Her eyes burned with more tears when she thought again over about what had just happened. So much blood...

"Remember me?" said Dean.

"Dean." Jenny said breathlessly. Of course she remembered him. She would have been happy if things were different.

"And Sam."

Sam, who was in the front seat, was watching her sadly. She couldn't remember Sam, but she knew those eyes – those puppy eyes.

"Justin and Kate..." Jenny whispered, trembling, trying to slide the wet hair out of her face, getting some blood on her cheek and in her hair. "Something killed them." Another tear fell. "Uncle John... it looked like me."

John and Dean exchanged looks.

"Shape-shifter." said Dean. They hadn't been quick enough. It had gone to Jenny and her foster family.

Jenny faced down, panicking again. What would happen now? Where would she go? What would they do with her...? She had no clue what a shape-shifter was but she didn't care. All she knew was that something that looked like her had killed Justin and Kate. They were both dead. It might as well have been her.

"Jen... we didn't get there in time to stop it... I'm so sorry." said John.

Jenny didn't respond, gripping at her hair. She wanted it to go away... everything to just go away.

"Jenny." Dean put an arm around her shoulders, trying to comfort her.

She looked up at him and then began to sob. Dean pulled her closer to him getting covered in blood stains and rain water. She shivered as he held her tightly.

"Jenny." John reached over the seat and took her hand. "It's gunna be okay. We'll keep you safe."

Jenny nodded, keeping her eyes shut tightly as tears streamed down her cheeks, mixing with the blood. "I didn't know what else to do. Stabbed it... silver butter knife..." She whispered in-between sobs. "It's dead. It's dead uncle John..."

The car was moving again.

"Okay." He replied. "That's good, Jenny, now it won't hurt anyone else."

Jenny sobbed. "She said they... thought it was... me. But I-I I didn't do it, uncle John. I didn't kill them."

"Of course, you didn't." said Dean. "What you saw was a shape-shifter. Maybe it looked like you, but it wasn't anything like you."

She sniffed. "Don't know... where to go..."

"Yes, you do." said John. "You're coming with us."

Oh I am so mean to my characters! I'm not telling anyone how she knows the Winchester's if you can't figure it out. A lot more information will be revealed in the next chapters.

Please review! Burn me with your flames - I don't care. I just want to know if you hate/like it XP
