Sam Winchester woke up screaming for the fourth night in a row.

"What's wrong?" asked a tired Jessica, "Tell me about your dream."

"It's nothing, it just . . ." Sam said unconvincingly, "Nothing."

"Obviously it isn't 'just nothing' if it's been keeping you up for the past four nights," Jessica said bothered that her boyfriend wasn't letting her in. Sometimes she felt like there was a whole other side of him that he didn't want her to see.

Sam fought with himself inside his head on whether he should tell Jessica about his past or not. He wanted her to know, but he didn't want to put her in danger. Finally he gave in and told her deciding that if the dreams he was having were to come true it would be better for her to know.

"So wait . . . you have a brother?" Jessica asked confusedly.

"Yes, his name is Dean and he helps my dad to try and hunt down this . . . this thing that killed my mother," Sam answered.

"So what does this have to do with the nightmares you've been having?" She asked.

"Not nightmares, nightmare," He responded.

"So what's this nightmare?" Jessica asked.

"Well I come home one night, and I'm really exhausted from a trip I'd just taken, so I instantly lay down on the bed. I'm lying there and all of a sudden I feel something dripping on my forehead. I reach up and touch it with my fingers, when I look to see what it is its blood. I look up to the ceiling above my head and you're lying there, just like my mother . . ." Sam trailed off.

"And then what?" Jessica asked.

"Then you burst into flames and I start screaming. That's where I wake up," Sam answered sadly.

"Well don't worry, that isn't going to happen," Jessica said reassuringly. "You aren't going on any trips any time soon, so you can't come back from one to find me dead."

"You know, you're taking this surprisingly well," Sam noticed all of a sudden, "Are you sure you don't think I'm crazy or something?"

"I don't think you're crazy Sam," Jessica said in a serious tone. "I used to have a twin sister named Jennifer, when we were thirteen she started seeing things at night. Everyone just assumed she was imagining things and ignored her, but I saw them too. In the middle of the night when we were alone in our room a . . . I don't even know how to describe this thing . . ." She trailed off.

"Please try, I might be able to tell you what it is," Sam answered.

"How would you know?" Jessica asked interestedly.

"I used to go hunting with my dad and Dean, we've encountered a lot of horrible things," Sam replied.

"Oh . . . okay then I guess," Jessica replied calmly as she began to think back about this thing. "Well . . . it was tall, about nine feet; its head almost touched the ceiling. And it had these glowing purple eyes with no pupils, that was one of the scariest parts. And it had rows and rows of teeth, when it opened its mouth you could see that there were at least ten of them. Its body was dark blue and it was slimy with a tail, it had two webbed feet, but also two without webbing." Jessica paused shuddering at the thought of the creature.

"It would show up in our room every night, one second it wasn't there, the next it was standing by Jenny's bed. The first few times it just stood there and disappeared the same way it came at one in the morning. But then it started to whisper her name over and over for the whole hour it was there, 'Jenny . . . Jenny . . .' its voice was inhuman, it was like nails on a chalk board. After a while it began to tell her how it was going to kill her by scratching her throat open over and over with plenty of detail, and right before it left it would come over to my bed and whisper 'If you tell anyone I'll kill you too,' then disappear." Jessica said.

"So what happened to your sister?" Sam asked curiously.

"Well when she told our parents they didn't believe her, but after a while they discovered that she was truly terrified and believed what she was saying, so they took her to therapy. I never told anyone what I'd seen because I was too scared, in fact once the therapist brought me in for a session and asked if I saw it and I said no." Jessica was crying now.

"And then one night I was at a friend's sleepover and when I came home the next morning Jenny was dead, her throat scratched open. And the worst part is that everyone believed that she had done it to herself. They said it was just a sad story and that she was mentally unstable and when forced to sleep in a room alone she just snapped and started scratching at her throat. But I know that that's not what happened," Jessica finished.

Sam held her close trying to comfort her while she cried.

After several minutes she stopped crying and looked up at Sam, "Do you know what did it?" she asked hopefully.

"I'm sorry, but I don't," he replied, "But trust me I'll find it."

Half an hour later the couple woke up to the footsteps of someone in the living room.

"Follow me," Sam whispered to Jessica as he got out of bed and walked into the hallway.

When they got to the living room Sam saw a shadowy figure standing in front of him and instantly attacked. They fought for a couple minutes while Jessica stood in shock until she found the light switch and turned the light on.

"Dean?" Sam asked surprised.

"Yeah, now get off of me," Dean responded irritated.

After both of the men stood up Sam introduced Jessica and Dean to each other. Holy crap she's perfect, thought Dean, it just figures that Sam's already taken her.

"Just call me Jess," Jessica said kindly to her boyfriend' brother, "I'm just going to go throw some clothes on."

"Oh, no please don't," flirted Dean, "I like the Smurfs."

Dean turned to Sam and said, "If only there were two of her!"

Jessica instantly ran over to where Dean stood and bitch-slapped him across the face as hard as she could.

"What the hell was that for?" Dean asked.

"She used to have a twin," Sam answered pulling Jessica away from Dean and holding her hand.

"Oops," Dean responded embarrassedly.

A few moments of awkward silence went by before Sam asked, "So why are you here breaking into my apartment at four in the morning anyways?"

"Oh right," Dean responded, "I need to talk to you alone."

"Whatever you're going to say you can say in front of Jess," Sam said sternly.

"Ok," Dean said, "Dad's on a hunting trip, and he hasn't been home in a few days."

Shock spread across Sam's face.

"Wait you mean like with . . ." Jess, who was very new to this, trailed off.

"Yeah with ghosts and stuff," Sam replied.

"Wait you told her!" Dean said angrily.

"Yeah, and she's coming with us," Sam answered surprising both Dean and Jess.
