Chapter 3

"Allison Jane Farrell, are you telling me that you just broke the one rule we set up for ourselves?" Addison asked her voice was tight as she stood from her bed.

"It was one night, Addie!" Allison exclaimed. "They're here on a job and we'll probably never even see them again after they leave."

"Allie, I'm glad you finally shook off the funk you've been in; but with another hunter? You couldn't have picked someone else in the bar?" Addison asked and Allison sighed as she ran her free hand through her hair.

"It's not my fault he was the first guy since Kyle to make me feel all weak in the knees," Allison said as she sank down on the bed and turned her eyes to the fading carpet on the floor of the room. Kyle Sharper had been the last guy Allison had any sort of 'more than friends' relationship with.

Three years earlier, he'd been killed because of her, and it still haunted her; especially since Kyle had accepted the life she led. It had taken him a week to wrap his head around things after she confided her family secret to him. Addison and Allison had left town for another job and she was certain that Kyle wanted nothing to do with her after that. Needless to say it had been the shock of her life when he showed up at their motel, flowers in hand and told her he loved her despite all the crazy and baggage she brought to the party.

He had quit his job and said he wanted to fight alongside them. Addison had even trained him in basic combat, but it hadn't been enough. They had been on a simple salt and burn job in Oklahoma, or so they thought. The spirit was a lot stronger than the trio had been expecting and when Allison and Kyle had gone to investigate the building during the evening, it had gotten the better of them. Allison barely made it out alive as she dragged Kyle's lifeless body outside. It had taken Allison two months to recover from her physical injuries and in a way she was still recovering from the emotional scars she carried. However, the hours she had been with Dean she hadn't felt so empty inside but Addison was there to remind her just how bad of an idea it was to get involved with someone like Dean.

"How did you figure out they were hunters?" Addison asked quietly, feeling guilty for making her sister feel like crap for having a little fun.

"Dean's got a protection tattoo on his chest," she said and Addison mentally cursed herself for not realizing the boys' profession sooner. She usually could spot another hunter a mile away, but for some reason he boys didn't give off the vibe to her.

"And you slept with him anyway?" Addison asked and Allison rolled her eyes.

"Look, we'll leave in the morning if you want and put as much distance between us and them as possible. We'll find another place to crash and look for a job." After a few beats of silence from her sister, Allison shook her head and started for the bathroom.

"Maybe we can give them a hand with the one they're working," Addison said and Allison stopped before she crossed the threshold of the bathroom door. She turned around and looked at her sister with a small frown.

"What?" she asked and Addison sighed as she stood from the bed and walked over to her sister.

"Do you know how long they've been on the case or what it's involving?" Addison asked and Allison shook her head negatively.

"We didn't really talk about it. We were sort of occupied," Allison said and Addison laughed, which made Allison blush.

"Alright," Addison said before she turned around and headed for the door.

"Where you going?" Allison asked with a frown and Addison looked over her shoulder as she opened their motel room door.

"Don't worry not far," Addison said before she left the room. She was only in her socks and pajamas, so, Allison knew she really wasn't going far. Shaking her head in mild confusion, Allison went into the bathroom and closed the door behind her.

Sam had just come out of the bathroom when there was a soft knock on the door. He sighed and tossed the towel he was using to dry his hair on one of the dinette chairs before he glanced at Dean who was still out for the count. He figured it was Allison and that she realized she had forgotten something in the room so she had came back. He moved in front of the door and opened it a crack like usual only to frown when he saw Addison standing on the other side of the door dressed in a gray tank top and light blue pajama bottoms with yellow smiling faces on them.

"If I promise to talk in a whisper, can I come in?" she asked and Sam nodded before he opened the door further and she walked inside. Addison shook the chill from her body thanks to the cool night air and turned around to crane her neck up to look Sam in the eye. "You know, you don't look like a hunter," she said and Sam's eyebrows rose as he looked down at the petite woman in front of him.

"What?" he asked and Addison smiled. Everyone seemed to be a fan of that word that night.

"Allie told me," she said. "Dean's protection tattoo gave him away because Allie and I have the same one." Sam's eyes widened even more as he took in her words and Addison laughed quietly. "Don't look so shocked. Allie and I may look sweet and innocent, but we kick ass."

"Don't take this the wrong way, but you don't come across as sweet and innocent," Sam said, a grin on his lips and Addison rolled her eyes.

"Okay, so, Allie comes off as sweet and innocent," she corrected with a grin of her own. "Anyway, I came over because I wanted to ask you about the case you and your brother are working."

"Why?" he asked and Allison crossed her arms over her chest.

"Could you guys use a few more eyes?" she asked and Sam sighed quietly as he looked down at the carpet. They'd been in town for two days and hadn't made any headway on the case, and as much as he hated to admit it; fresh eyes would probably help. "I'm going to take your silence and look of contemplation as a 'yes'," Addison said as she uncrossed her arms and Sam returned his eyes to her. "Allie and I will be over in the morning. Eight okay? We'll bring breakfast," she said and Sam could only nod as she pushed past him and went to the door. "Good night, again," she said before she left and Sam scoffed a laugh before he locked the door and turned off the light. Tomorrow was definitely going to be interesting.

There was a faint pounding the back of Dean's head as he slowly came to and the sun shining in his face thanks to the open curtains wasn't helping. He groaned quietly before he turned his head and looked at the alarm clock on the stand in between his and Sam's bed. It was a little past seven and he stretched his arms over his head before he sat up.

"Morning," Sam said from where sat at the small table by the window and Dean looked at his brother, squinting because of the light. Sam was sitting in front of his lap top and focused on the computer as he searched for something.

"You're up early," Dean said as he rubbed the sleep from his eyes.

"Couldn't really sleep," Sam said. "Did you enjoy yourself last night?" The memories of the previous night's activities came rushing back to Dean, and he smiled as he turned away from his brother and found his jeans still on the floor with his boxers tucked inside.

"You have no idea," Dean said as he snatched his boxers from yesterday and pulled them on as he stood up. "And, dude, she's -"

"A hunter, yeah, I know," Sam said and Dean frowned as he turned around and looked at his brother.

"I was going to say really flexible," he said and Sam scoffed and shook his head. "How did you know she was a hunter?"

"Addison stopped by last night after Allison went back to their room," Sam said. "You might want to get dressed; they'll be here around eight."

"Why?" Dean asked and Sam gestured towards the computer and the research he had spread out on the table.

"To give us a hand," Sam said and Dean's frown deepened.

"Seriously?" Dean asked and Sam nodded.

"Addison offered to help, and I took her up on it," Sam said. "We've hit a brick wall with this one, Dean, and fresh eyes won't hurt." Dean sighed before he ran his hand over the top of his head and went to his bag to get some fresh clothes to change into after his shower.

"Alright," Dean said. "I'm taking a shower and then going to get something to eat."

"Addison said they'll bring breakfast," Sam said and Dean smirked as he grabbed his clothes.

"I knew I liked her," Dean said before he went into the bathroom and Sam rolled his eyes once more and returned to his research. Dean was still in the shower when there was a knock on the door. Sam glanced at his watch and saw that it was quarter to eight, and he stood and went over to the door. He smiled when he saw a smiling Addison and a tired looking Allison standing on the other side of the door. Addison was holding a pastry box and Allison a tray with three coffee cups as she sipped on a cup in left hand.

"Good morning," Addison said as she walked into the room and past Sam. He laughed quietly as he followed her with his eyes before he looked at Allison.

"Someone put a quarter in her this morning, so, I hope you can handy the peppy," Allison said and Sam laughed as he closed the door. "We weren't sure how you guys took your coffee so we just ordered it black and grabbed handfuls of creamer and sugar packets," Allison said as she carefully put the tray on the table to avoid setting it on any of the printed photos Sam had scattered on the table that morning.

"Thank you," Sam said with a genuine smile as he looked down at Allison and she gave him a sleepy smile in return. Despite the slight outer alterations, they truly were identical and even if Addison's hair wasn't shorter and her eyebrow pierced he would be able to tell the difference. Allison's eyes seemed more haunted then Addison's, and at that moment reminded him almost painfully of the look he had caught in Dean's eyes on more than one occasion lately. When Allison frowned and looked away from him, he grabbed a cup of coffee from the carrier and sat it on the table before he took off the lid and grabbed a couple sugar packets Allison had pulled out of the pocket of the black jacket she was once again wearing.

"So, where's your brother?" Addison asked as she opened the pastry box and grabbed a glazed donut from inside before settling herself in the chair Sam had been sitting in and crossed one leg over the other.

"Right here," came Dean's voice and Addison looked towards the bathroom and smiled before she looked at her sister. Allison turned around and looked at Dean as he walked out of the bathroom, towel in hand as he ran it over the back of his short hair. He was dressed in dark jeans and a fitted gray t-shirt. He smiled at her and Allison smiled back before she looked away from him and took a drink of her coffee. Dean walked over to the nightstand and picked up the ankle sheath and knife before he put the towel down in its place. "Allie," he said and she returned her eyes to his and he held the sheath out to her. "You left this."

"Thanks," she said as she laughed lightly and grabbed the sheath with her free hand, purposefully brushing her fingers against his as she did so. He nodded and looked at the table.

"So, what's for breakfast?" he asked before he grabbed a cup of coffee and a donut from the box.

"You must have had fun last night," Addison said in Gaelic and Allison turned her eyes to her sister. "Since Dad gave that to you, you never go anywhere without it. So not like you to forget it somewhere." Sam and Dean looked at the woman as she spoke in a language they didn't know and then looked at Allison, whose cheeks were a bright shade of pink.

"We are not having this conversation now," Allison said quickly before she looked at Sam and Dean and forced a smile. "Sorry. Don't mind her too much, she's only slightly crazy." Addison laughed lightly before she grabbed her own coffee after stuffing the last bite of her donut in her mouth.

"What language were you just speaking?" Sam asked and Allison looked at him.

"Gaelic," Allison said and at their frown she laughed and explained further. "It's Irish. Our grandfather taught us when we were kids."

"Comes in handy when we need to talk about things in secret," Addison said, a grin in place.

"Addie," Allison warned as she kept her face towards Sam and Dean as she closed her eyes and shook her head.

"What? It's true. No one really knows it, and faces like the one you two are making always make me laugh," Addison said before chuckled and she took a drink of her coffee. Sam and Dean laughed and shared a look before they returned their eyes to the sisters.

"Okay, now that share time is over, let's get started," Allison said as she opened her eyes and looked up at Sam and Dean's smiling faces. "What are you guys working on?"

It was nearly one o'clock in the afternoon and Addison and Sam had gone to get lunch for the foursome while Dean and Allison remained behind. Dean was paging through one of the books Allison had grabbed out of their truck, but he wasn't finding anything that was helping them. All they really knew was that people were dying, violently, in their sleep. According to the coroners reports two of the victims had multiple broken bones and one's organs had basically turned to soup. Three people had already been killed, and a fourth while they were on the job. Sighing, Dean looked up from the book resting on the table in front of him and looked over at Allison who was settled on the sofa.

She was sitting with her back against the arm of the sofa with her legs in front of her and bent at the knees while another book rested in her lap. She had put on a pair of black square framed reading glasses when she started paging through the books she had gotten out of the truck. Dean had to admit with her long hair pulled up into a high ponytail, the fitted white button up she wore with the sleeves rolled up to her elbows, and the dark jeans she wore along with the glasses evoked all sorts of 'hot for teacher' thoughts in his head.

"You know, it's rude to stare," she said, never taking her eyes off the pages in front of her and startling Dean slightly before she turned her head and looked at him with a small smile on her face.

"I wasn't staring," he said defensively, but Allison's smile grew.

"Okay, you can tell yourself that," she said before she sat up and swung her legs over the side of the sofa. She left her shoes on the floor and walked, bare footed over to Dean. "I think I found something," she said as she put the book down on top of the one in front of him and pointed to the pages. "There's old Scandinavian folklore about a creature called a Mare."

"A female horse?" Dean asked with a frown and Allison scoffed a laugh.

"No, not a female horse," Allison said as she turned her head and looked at Dean with a smile before she looked back at the pages. "It's a creature that sits on a person's chest while they're sleeping and causes nightmares, and I think this one might be making the nightmares of its victims a little more real."

"Can it do that?" Dean asked and Allison sighed quietly as she stood fully and put her hands on her hips.

"I don't know, but after five hours of scouring through all my father's old books it's the best I can come up with," she said as she raised her right hand to her reading glasses and pulled the frames from her face.

"Okay, so, how do we find it and kill it?" he asked and Allison furrowed her brow as a look of contemplation crossed her features. Dean simply watched her as she stood there thinking. He had nothing since he had never even heard of the creature before. Just then, Sam and Addison walked back into the room take out bags in hand.

"Awesome," Addison said as she looked at her sister's face and both Dean and Sam looked at her as she closed the door. "Allie's got her thinking face on, that can only mean one thing; you guys figured out what it is."

"Maybe," Dean said as he glanced at Allison, who had turned away from the other three and had started pacing the room a bit at the foot of the beds. "She okay?" Dean asked, looking at Addison and Addison nodded.

"Yeah, she's fine," Addison said. "It's a habit she got from our dad. Pace and think. Funny thing is, she always comes up with an answer after-"

"All four victims, the day they died, hiked along one of the more difficult trails in the state park right?" Allison asked suddenly, cutting off Addison as she quickly turned around and looked at Sam knowing that he would have the answer for her.

"A minute," Addison whispered to herself as she opened the take out bag from the Chinese restaurant they had gone to and started taking out the containers.

"Yeah," Sam said slowly and Allison walked back over to the table.

"The Mare must live along the trail somewhere," she said and Sam frowned.

"The what?" Sam asked and Dean picked up the book Allison had put in front of him and handed it to his brother. Sam's eyes quickly scanned the pages in front of him and his frown only deepened. "You sure this is what it is?" Sam asked as he looked at Allison and she shrugged.

"It's the best thing I could come up with," she said. "It's really the only thing that makes sense, and like I told Dean maybe this one is making its victims' nightmares a little more real."

"Now that everyone is caught up to speed, again I ask; how do we find it and kill it?" Dean asked as he took the container Addison held out to him.

"Well, I've got the 'finding it' part covered," Allison said as she looked at Dean and he looked at her.

"How?" he asked.

"Easy," Allison said. "I'm going for a hike."

"Wait, what?" Addison asked and Allison looked at her sister. "I'm not letting you be bait."

"I trust them," Allison said in Gaelic and Addison frowned.

"Why?"

"Think back thirteen years, Addie," Allison said. "Remember the other hunter that saved Dad? Remember his two sons that sat with us while he took Dad to the hospital?" Addison's eyes widened as she glanced between Sam and Dean before returning her eyes to her sister. "I didn't figure it out until this morning when Sam thanked me for his coffee. His smile brought me back. It all clicked into place and I figured out why Dean was so familiar when I first met him."

"Okay, I don't know what you just said, but our names were definitely in there," Dean said and Allison looked at him. They looked at each other for a second, but before Allison could say anything Sam spoke.

"We don't know how to kill this thing yet, Allie," Sam said as he looked down at her. He knew she had said something about them, but he really didn't care about that right then. He was worried about Allison acting rashly.

"It's a type of goblin, so, one of two things should work; silver or fire," Allison said.

"And if it kills you before we stop it?" Dean asked, not liking her idea at all.

"That's a chance I'm willing to take," she said her eyes meeting his. "I trust you and I trust Sam; and I know I can trust Addie. I'm doing this." Dean sighed quietly at the resolution in her eyes. He knew that there was no way they were going to be able to talk her out of it.
