Supernatural

Sam was running as fast as he could. He wasn't sure what he was running from. All he knew was whatever was chasing did not want him to live.

Sam finally stopped in front of an abandoned house. He shut the door so nothing would come in and backed away. Just then something or someone grabbed him from behind throwing him to the wall. He was facing this person, but it was so dark that he couldn't make out the shadow.

Then the stranger pulled out a knife striking down with all its might in to Sam's chest as he gasped.

Sam shot up from his sleeping position sweating. Dean was looking over at him from the restroom while brushing his teeth.

"I heard groans. Was it a happy dream or a bad dream?" Dean smirked.

"Bad." _

Dean and Sam seemed to have the week off because nothing strange has happened in a couple of days. They were at a bar in Kansas: Dean was having some drinks while Sam tried looking for a case just so he can get his mind off the dream. When he gave up on the research he just closed his laptop and rubbed his eyes.
It was then he felt a light pull. He looked around trying to see where that was coming from. He saw from across the bar that the doors shut with a shadowy figure leaving.

Sam's eyes got wide. Dean noticed his brother looked like he saw a ghost, well he's seen them plenty of times, but you know what I mean. Dean walked away from the girl he was flirting with and over to his brother.

"What do you see?"

"It's what I feel. Something's wrong."

"Let's check it out."

As they were in the ally they didn't see anything.

"Are you feeling okay? Was it that dream that's getting to you?"

"I don't know anymore. I felt something leading me here though."

"Maybe we should ask Bobby. He'll know what to do."

The boys made it all the way to Bobby's with nothing strange happening. Bobby had no clue how to solve their problem.

"Maybe you're just imaging things, Sam," Bobby said trying to convince him things were fine.

"Maybe, but it was a strong pull."

"You've been saying a name in your sleep lately," Dean threw in.

"Why didn't you tell me?"

"I didn't think the dream got to you."

"What was it?"

"Emmalynn or Emma. Even Em."

Bobby's eyes got a little big at that name, but Sam and Dean didn't seem to notice.

"I don't even know an Emma."

"Apparently you do. Was it a one night stand?" Dean smirked.

"Dean this isn't funny. Every time I dream about her she tries to kill me."

"So it was a one night stand. Sammy, you dog," Dean was not showing an ounce of seriousness; which started to frustrate Sam.

"Do you know what she looks like?" Bobby asked trying to prevent a fight.

"No, all I see is a black shadow."

"Could it be a shadow demon? Like a Daeva?" Dean asked trying to get serious again.

"No I don't think they have personal name. Besides it wasn't like an actual shadow killing me. It was just a dark figure that stabbed me."

"Well we can't do anything about it until we get more clues. We can talk about this in the morning," Bobby turned and left to go to sleep.

Sam fell asleep at the desk with his laptop on being the only light. He was still trying to figure out what was killing him in his sleep. He was the only one in the room when a noise awoke him. Sam blinked a few times looking around. He stood up closing the laptop when he heard another noise.

Sam started to get a little uneasy, "Dean?" he called out, but no reply. Anxiety filled Sam as he walked toward the entrance the hallway. Still, nothing was there.

Just as things seem perfectly fine Sam turned and saw a figure in front of him. Not being able to speak, the figure right hooked him and dragged him back in the room. Sam was then shoved back a few feet past the window where moonlight was seeping through. The figure stepped toward Sam and went passed the light giving Sam a second to make out some features.

He saw her dark wavy hair and very similar facial features to a creature he once knew.

"Ruby?"

The figure stopped in her tracks, "Who the hell is Ruby?" she spat out with anger.

Sam then in an instant grabbed a random book off the desk and threw it at her which she blocked away with her hand. She charged at him with a tackle pushing him on the desk. She then lifted her leg to stomp him in the stomach. He took her leg and threw it to her left side making her spin.

When she got her balance back, she leaped at him starting to punch him in the face with everything she had. Sam grabbed her by the hips and pushed her off.

"Who are you?" He yelled.

"A pissed off girl that's who!" She left hooked him but Sam grabbed her arm and stopped her. He turned her around to where his arms were wrapped around her as she struggled to get out.

"I don't know who you are."

"At this point, I wouldn't want to know me either," She jumped up head butting Sam in the chin, releasing her.

"The way I look at it Sammy, one of us is going down. Since I already have it's your turn!" She pulled out a knife from her jacket. She ran to him but he smacked the knife out of her hand. The girl grabbed his shirt and pulled him to the side and let her left foot out so she would trip him.

A loud thud was made when Sam hit the floor. The girl got on top of him with the knife in her hand, raising it high over her head. The moonlight hit her eyes and Sam a good look at the one causing his death. Her eyes were different from Ruby. It was a different shape and they were much darker.

Sam saw something in that girl. Something you don't see in a lot of killers eyes when they're about to murder someone. He saw sympathy and pain. Is she hesitating?

A manly hand grabbed the mystery girl's arm. As she looked to who it was another hand made into a face clocked her. She was out cold. Sam looked up and saw his brother standing over both of them.

"I guess we found your one night stand," Dean said sarcastically.

Sam and Dean tied up the girl to a chair under the Devil's Trap sign. The girl was starting to come out of a daze.

"Hey, hey wake up, bitch!" Dean ordered.

As she woke up she started to look around. When her eyes fell upon the symbol above her she stared to chuckle.

"A Devil's Trap, is that what you guys think I am; a demon?"

"You tell me. How did you get in here?"

"I snuck in, dumbass," she spat out.

"Why are you trying to kill my brother?"

"Ask him that. I'm pretty sure he remembers."

"I'm asking you."

"Look this doesn't concern you, Dean! Now how about you let me take an eye for an eye so I can kill your brother."

"How do you know our names?" Dean was now a little less angry, but way more serious.

"Well, me and you never met. Sam, on the other hand, we have."

"Look, I don't remember you," Sam was trying to get it through her head, "I don't remember a year and a half. So whatever I did I'm sorry."

"You're sorry? That's it? Well 'I'm sorry,' Sam, but that doesn't cover the fact that you killed me!"

The room was silent. Dean looked over to Sam whose face was completely oblivious.

"Don't act so baffled, Sam. Trust me I wasn't, afterwards," The girl said bitterly.

Sam started to explain an apology, "I would never—,"

"Hurt me? Kill me? Yeah, I thought the same thing too," she said with shame on her face.

"What's your name?" Dean asked.

"Emma, Emma Monte."

"Okay then, Emma, did you and Sam date or something?"

"I wouldn't call it dating. That would mean both partners would show some emotions!" she yelled to Sam.

"Alright," Sam said frustrated, "I had no soul!"

"You think? I'm proof of that statement!"

"No seriously, I had no soul. So the Sam you knew wasn't me."

"What the hell are you talking about?"

"I went to hell-," Emma interrupted, "You told me that much."

"I came back with no soul. Then a year and a half goes by and I get it back which makes me forget everything, including you."

Emma was a little confused but she understood, "You might have forgotten, Sam, but I still remember it. From the day I laid my eyes on you, to the night you shot a bullet between them."

Sam looked down; he didn't know what to think. Dean decide to break the tension, "So if you weren't dating, then what were you?"

"Let's just say I was Sam's private 'fun toy'," Emma said with sarcasm. Dean and Sam both got a face that said, "Whoa!"

"You mean you two-,' Dean pointed to her and Sam. Emma nodded, "Everywhere he went, I was riding shot gun. Not to brag, but him too," Sam started blush a little.

"We didn't do only that. I helped you on hunts," Emma added.

"You're a hunter?" Sam asked.

"Yeah, well was. I only did a few hunts when I was younger and then after I met you it became my life."

Another quite moment until Emma spoke, "Can you untie me now?"

"Are you going to try and kill us?" Dean smarted.

"Depends on if you piss me off."

"How about you tell us your little story and I'll cut the ropes."

"Fine! I'll tell you everything."
