Chapter 10

Dean looked at Allison who sat behind the wheel of the truck, gripping the steering wheel tightly. It was dark and the small Oklahoma town was quiet. Sam and Addison had stayed behind at the motel to check them in and get two rooms for the four of them. Addison had wanted to go along with Allison, but Dean insisted that he go with her especially since he now knew why Allison had been so upset a couple of days ago after she had gotten the phone call about the job.

He now knew a little bit about who Kyle was and who he had been to Allison, and in truth he was a little jealous but he also knew that his past was littered with women and he could only really remember the names of two. Until Allison they had been the only ones that meant anything to him, but they were distant memories now and he was concerned about the woman in front of him as she took slow deep breaths as she quietly readied herself to face the owner of the house they were parked in front of. The house had a porch light on and the large window was lit by light on the inside, but the curtains were closed and he couldn't see inside.

"Allie, you okay?" Dean asked quietly and Allison nodded as she finally let go of the steering wheel and unbuckled her seatbelt before she turned her eyes to Dean.

"Yeah, Dean, I'm okay," she said. "I'm just a little nervous."

"Don't be," Dean said. "I'll be right there with you." Allison smiled then and nodded before the two of them climbed out of the truck and headed up the walkway. Once they reached the door, Dean rang the doorbell while Allison stood at his side. He sent a look her way just as the door swung open. Dean turned his eyes ahead and saw an petite older woman with graying brown hair and aged eyes hidden behind a pair of glasses.

"Allison, you're here," she said softly before she pushed the screen door open and looked at Dean with a small frown as the two of them walked inside.

"Hell, Margaret," Allison said as Margaret closed the door. "This is my friend Dean. He and his brother, Sam, are . . . they do what Addie and I do and they've come to help us." Margaret nodded before she looked at Dean once more and settled her eyes back on Allison.

"Where is Addison?" Margaret asked.

"She and Sam went to the motel to get our rooms," Allison said. "It's late and I really didn't think that you'd want a whole bunch of people in the house." Margaret nodded again before she led them into the living room and gestured for them to sit down. Dean could feel the slight tension between the two women, but he acted as though he didn't.

"Would either of you like something to drink?" Margaret offered and Dean shook his head.

"No thank you, ma'am," Dean said and Margaret sat down on the arm chair across from the sofa Dean and Allison sat on. "Allison told us what you told her, but I do have a few questions."

"I'll try to answer them," Margaret said as she adjusted her glasses and looked between the two of them.

"Do you know how long it takes for this . . . sickness to run its course?" Dean asked and Margaret sighed.

"A week, I think," Margaret said. "Carl, Mable's husband, started feeling sick last Sunday after church. Mable thought it was a bug of some kind, but when he got worse the next day she took him to the hospital. By Friday he was in a coma and he died the day I called Allison."

"It is a week," Allison said and Dean looked at her. "She called Sunday morning." Dean nodded and looked back at Margaret who was yet again looking between the two of them with a curious expression on her face. "Who else has died from this mysterious sickness?"

"Three others and four more people are in the hospital," Margaret said. Dean and Allison continued with their questioning until they had all the information they were going to get out of Margaret. "I wish there was more I could tell you," Margaret said, thirty minutes after Dean and Allison arrived.

"You gave us enough to start with," Allison said as she and Dean stood from the sofa. "We'll let you know when we stop it." Margaret nodded as she too stood. The three of them walked to the front door, but Margaret reached out and grabbed Allison's arm. Allison stiffened and looked to her left, her light eyes meeting Margaret's brown.

"Can I talk to you a moment, Allison?" she asked and Dean turned around to look at the pair just as Margaret turned her eyes to him and lowered her hand from Allison's arm. "Alone," she said and Dean looked at Allison and she nodded at him to let him know it was okay.

"I'll wait in the truck," he said and Allison handed him the keys. With an encouraging look, he left the house and Allison sighed quietly as she turned around to face Margaret.

"I know you were dreading coming here, and I can't say that I blame you," Margaret said. "I wasn't very kind the last time we talked."

"You were grieving, Margaret, and Kyle died because of me," Allison said. "You were right to be angry." Margaret sighed at the young woman's expression and the guilt that had been eating at her for the last three years rose completely to the surface.

"Allison, it wasn't your fault that Kyle died," Margaret said and Allison frowned. "Kyle loved you, and he gave up everything to be with you because he loved you so much."

"I loved him too, and shouldn't have let him stay with us," Allison said. "I should have told him to go back home the second I opened the motel room door and saw him standing there."

"He wouldn't have listened, Allison," Margaret said with a small, sad smile on her face. "Believe me, I tried. Kyle chose to follow you. He chose to . . . to do what you do. It was no one's fault he died, and you nearly died yourself. I shouldn't have said what I did to you that day, and I'm sorry." Allison sighed quietly as tears lined her eyes and she was seriously getting tired of crying. It seemed like all she ever did was cry any more. Margaret pulled Allison into her arms and hugged her tight. Allison hugged her back just as tight. After several seconds, they pulled apart and Margaret and Allison laughed lightly as Allison wiped at her damp face.

"Thanks," Allison said. That was all Allison could come up with, but Margaret seemed to understand what she meant all the same. "I should get going. We had a long drive and if we're going to be any good tomorrow, we all need to get some sleep." Margaret nodded and the two said their good-byes before Allison left. Despite the chill in the air, Dean wasn't waiting inside the truck like she had been expecting. He was standing on the curb, leaning back against the truck with his hands in the pockets of his leather jacket as he looked towards the house. Allison drew her jacket around her and closed the distance between them. When she reached him, Dean stood straight and looked down at her.

"You okay?" he asked and she smiled at his concern.

"Yeah, I'm okay," she said. "That wasn't as bad as I thought it was going to be." Dean sighed quietly in relief before he pulled her close and kissed her forehead. Allison took a deep breath, breathing in Dean's scent as she closed her eyes and her body relaxed on instinct against his.

"You want me to drive?" he asked into her hair and she nodded as she pulled back.

"If you can handle her," she said with a smile and Dean smirked as spun the keys to the old truck in his right hand.

"Sweetheart, you know I can," he said and Allison rolled her eyes as he opened the passenger door for her and she climbed in.

She had been tense from the moment Margaret had called two days earlier and now that the moment she had been dreading had come and gone she was exhausted and she closed her eyes as she rested her forehead against the cool glass of the window. After Dean started up the truck, put it in gear, and started down the road, he reached over and encased Allison's left hand in his right. However, when she didn't respond he glanced at her only to smile as his eyes returned to the road. She was in the truck for not even five minutes and she was already asleep.

Addison sighed quietly as she sank down on to the curb of the sidewalk that lined the rooms of the motel they had checked into. The room had felt stuffy and confining after she had showered and tried to watch some mindless television. She couldn't relax because her mind was with her twin and her imagination was running a bit wild with what was happening while Allison and Dean were with Margaret. Addison had never officially met the older woman, she really had no desire to, but the conversation that they had shared was very unpleasant. She was pulling her coat around her body a little tighter when she heard a door open.

She looked over her right shoulder only to see Sam leaving his and Dean's room before he walked down the sidewalk and to a car waiting in the shadows. Addison frowned as she saw a young woman step into the limited light by the car. Sam and the woman were talking and Addison didn't like the smirk that graced the woman's lips. The way the light was shining on her face made her look almost sinister and a shiver ran up Addison's spine that wasn't from the cold. Quick to her feet, Addison marched as quietly as she could down the sidewalk and up to the whispering couple.

"Sam?" Addison questioned and she saw Sam's shoulders stiffen as the woman looked at her with a raised eyebrow. Sam turned around and looked at her. "Who's this?"

"She's the friend I was telling you about," Sam said and Addison's frowned returned.

"The one that's helping you track Lilith?" Addison asked before she looked back at the woman.

"Come on, Sam," the woman said, choosing to ignore Addison's question. Sam sighed and glanced at the other brunette before he looked back at Addison.

"I'll be back in a little while, Addie," Sam said as Addison's eyes returned to his, "and I need you to do me a favor."

"What?" she asked not liking the feeling his words brought. She wasn't sure what was going on, but she didn't like the vibe the woman gave off. It was familiar and . . . dark.

"You can't tell Dean, or Allie, that she was here," Sam said and Addison gave him a look.

"Why not?"

"They don't exactly get along and even though he's not so against her anymore, she's not his favorite person; and Allie will tell him she was here if you told her."

"That's a lame excuse, Sam. Tell me the real reason why you don't want your brother to know she was here," Addison said and Sam stepped closer to her, his hands rising to rest on her shoulders.

"Please, Addie," Sam said and she sighed as she glanced at the woman to see her smirking again and Addison shot her a quick glare before she pursed her lips and looked back at Sam.

"Fine, but I want to know what's going on," she said and Sam lowered his hands from her shoulders. He didn't say anything, only nodded, before he and the woman climbed into the car she had drove up in. As the car drove out of the motel lot, Addison wrapped her arms around her waist as a frown once again made its way across her face. Something wasn't right about that woman and the way Sam was acting. She could just feel it, and she didn't like it. She didn't like it one bit.

The following morning, Allison had gotten up early and climbed into the shower before Addison had even stirred. Dressed in a black pencil skirt and soft blue button up that would be covered by her fitted suit jacket, Allison was putting the finishing touches on her makeup and tightened the high ponytail she had pulled her hair into. When Dean had been attempting to carry her into the motel room, she had woken up and they put together a plan before parting for the night and going to bed. They were going to pose as CDC agents at the hospital while Sam and Addison were going to do the same, but talk to the families of the people that were either sick or that had already died.

"Allie, do I have to take my piercing out?" Addison questioned from the bathroom and Allison smiled as she walked towards the open bathroom door. Addison was dressed similarly to Allison only Addison was wearing black slacks and a dark red blouse. On her head was the very realistic dark brown shoulder blade length wig that Addison wore on occasion, especially when she hadn't been able to get her hair done. She was wearing it that morning to hide the blue streaks in her hair and if it wasn't for the piercing in her eyebrow one would think she was her sister. "It's bad enough that I'm wearing this wig, and it might close before I get the chance to put it back in."

"I think you'll be fine," Allison said. "I don't think anyone will really notice it if you comb your hair just right." Addison smiled at Allison before she picked up their hairbrush and a knock sounded at the door.

"That's probably Dean," Addison said and Allison nodded.

"Call if you find out anything," Allison said.

"I will, and you too, okay?" Addison asked and Allison nodded again.

"Yeah," Allison said as she started to turn away, but stopped and looked back at her sister. "This feels weird." Addison paused in her hair brushing and looked at Allison.

"What feels weird?"

"Leaving you behind and going to the hospital. I'm used to it being you at my side when we're doing the leg work," Allison said with a furrowed brow and Addison smiled.

"I know, right?" Addison asked and there was another knock on the door, a little firmer and louder than the first. Allison rolled her eyes while Addison laughed. "Good luck."

"Thanks," Allison said before she walked away from the bathroom door and grabbed her suit jacket from where she had draped it on the back of the chair at the table. She opened the door just as Dean raised his hand to knock again and she smiled at his scowl. "Morning," she said and Dean cleared his throat as he lowered his hand and adjusted his tie.

"Hey," he said. "Ready?" She held the door open with her foot as she pulled on her suit jacket.

"Almost, come in," she said and Dean put his hand on the door, allowing her to step away. He followed her inside and closed the door. "I just have to get my jacket and I'll be good to go."

Dean watched her walk over to the bed, the skirt hugging her hips and the black heels giving her added height and making her legs look long and lean. He was a little disappointed when the long dark coat hid her curves from his eyes, but when she turned around after grabbing her reading glasses from the bedside table. As he watched her put her glasses on, he smiled.

"What?" she asked as she glanced to the bathroom door, relieved to see that Addison was still tucked into the room. She hadn't told her sister about the shower confessions she had shared with Dean, and the look Dean was giving her would have led to questioning from her twin.

"Nothing, you're just . . . beautiful," he said still smiling and Allison blushed as she returned his smile with a small one of her own. "Let's go." Allison nodded and the pair left the room and headed towards the Impala.

Addison sighed quietly after she heard Allison and Dean leave the room before she looked at her reflection. She had stopped herself many times over the last twelve hours from telling Allison what had transpired with Sam the night before. Somehow, Sam had made it back before Dean and Allison and once again asked her not to say anything to Dean or Allison. When she asked if the woman had any leads on the demon she was supposedly helping him to find, he only told her that 'she was working on it.' She had also asked him what he had been doing with the woman, but he didn't answer and she made a decision then and there. Whatever feelings she knew she was starting to have for Sam, she was going to push them away.

Sam was a great guy, but she knew that something wasn't right. His desire for revenge against Lilith was understandable. She had held his brother's contract. She was the one who unleashed the Hellhounds on his brother. She was the one who was breaking seals and trying to set Lucifer free to start the apocalypse. Addison understood his motives completely because if she would have been in his shoes, she probably would have been just as blood thirsty. However, the secrets he was carrying wasn't something she wanted to get involved in. A knock sounded on the motel room door and she sighed as she turned away from the mirror and turned off the bathroom light before she made her way into the room. She just knew it was going to be a long day.

"And all their tests have come back negative?" Dean asked as he handed the medical files over to Allison who started to page through the file on top while Dean talked to the doctor in charge of the four patients currently in the hospital; all in various stages of the 'sickness.'

"That's what has us going in circles," the older doctor said as he ran a hand down his weathered and stress lined face. "We've ran every test possible, given them as many medication cocktails as we dare, but nothing seems to be working. It's like they're just going to sleep and dying. Nothing's wrong with any of them." Dean sighed quietly as he looked through the glass wall and at the patient who had been in the hospital the longest. Darren Solomon. He had slipped into a coma the day before, which meant they had less than forty-eight hours to try and stop whatever was happening and save everyone's lives.

"Is it okay if we take these? I'd like to review them with one of our partners that's currently talking to a few of the decedents' families," Allison said and the doctor nodded.

"Of course," he said.

"We'll be back, Doctor," Dean said as he pulled a card from the inner pocket of his suit jacket, "but if any of their conditions change or you find anything new, please call me." The doctor took Dean's car and nodded his head as he looked at it and then at Dean.

"I will, thank you," he said and Allison and Dean left the hospital. Dean was loosening his tie before they even reached the car and Allison was thinking over their conversation with the doctors. All of the victims that had died were over sixty, and the latest victim to sleep into a coma was in his mid fifties; however, the other three that were in the hospital were between Allison and Dean's age.

"Do you have any idea what this could be?" Allison asked as she glanced at Dean and he sighed as he pulled his tie from around his neck and stopped next to the Impala with Allison stopping right next to him, her hip resting against the car.

"Not really," Dean said as he stuffed his tie into his jacket pocket and Allison took a deep breath before she pushed her glasses up into her slicked back hair. "Hopefully, Addie and Sam are coming out better than we did. Maybe they can get a common thread between the victims."

"Maybe," Allison said. As far as they could tell they were along in the parking garage and after a quick glance around them, Dean put his hands on Allison's waist and pulled her close. She laughed lightly and silently wished her hands weren't full so she could wrap her arms around him in return. They smiled at each other and Dean's hands caressed her body over her clothes and Allison shivered slightly when she felt the heat of his gentle hands seep through her clothes. "We're on a job, Dean," she said quietly as she pulled her head back from his descending lips.

"True, but we got nothing right now and we can't really do anything until-," Dean's words were cut off by the ringing of his cell phone. He groaned as he pressed his forehead against her. Allison laughed again as his right hand left her waist and pulled his phone from his jacket before he raised his head and brought the phone to his ear. "Yeah?" he questioned, his green eyes focused on Allison's face. "We just finished up at the hospital, and didn't get much more information than we already know," he paused before he sighed and nodded his head though Addison or Sam couldn't see him. "All right, we'll meet you at the motel." He hung up and stepped back from Allison. "That was Sam, they think they might have a link."

"Great," Allison said before she turned away from Dean and walked around the hood of the Impala. They climbed into the car and were on their way back to the motel to meet their siblings.

"Looks like we beat them back," Dean said with a grin and Allison looked at him briefly before she rolled her eyes and got out of the car. "What?" he asked as he followed her out and she smiled at him.

"I know that grin, Dean Winchester, and no," she said through her smile before she started towards his and Sam's room.

"No what?" Dean questioned as he quickly followed her and pulled out the key to the motel room. They came to a stop outside the door and she looked at him with a raised eyebrow. Dean's grin was back as he slowly licked his lips and moved a little closer to her. "Okay, we won't go that far, but a little kissing never hurt anyone," he said as he discretely slid the key into the lock and turned it as he kissed Allison gently. The files were tucked into her left arm and she raised her free right hand up to the side of Dean's face as he pushed open the door and pulled her inside, slamming the door behind them. Allison giggled against his lips as he ripped the files from her grasp and tossed them on the table before he threw his left arm around her and crashed her body to his as their lips battled.

"Dean," a gravelly voice said, making Allison gasp as she pulled away from Dean, but Dean kept her close and hidden from the source of the voice as he looked over his right shoulder. Dean sighed heavily before he looked down at Allison and gave her a tight lipped smile.

"Don't worry, I know him," Dean said dryly before his grip loosened on the woman in his arms and he took her right hand with his left as he turned around to face the man in the trench coat that stood between the double beds. Allison looked at the man with a frown. His blue eyes settled on her, and a look of contemplation took over his features. "Cas, what the hell are you doing here?" Dean asked and the angel looked away from the brunette at Dean's side for a second before his eyes returned to Allison.

"You shouldn't be here," Castiel said quietly as he took a step around the bed, his eyes still focused on Allison. "It is too soon." Allison frowned as she looked away from Castiel to Dean who looked just as confused as she was.

"Cas?" Dean questioned and Castiel finally looked away from Allison and at Dean, a small frown on his face. "What are you talking about?"

"Nothing," Castiel said as he glanced at Allison. "It is not important."

"Okay," Dean said slowly. "What are you doing here?"

"You're wasting your time here. The cycle will end after the seventh death in the, and there is nothing you can do to stop it from happening. The source of the sickness is dormant and will not reactivate," Castiel said. The coldness in his tone didn't really surprise Allison, and she remained silent. Dean had told her the angels he had met were dicks, but that he had hope that Castiel was a little different. However, he didn't seem so different to Allison.

"What do you mean we can't stop it?" Allison asked as she let go of Dean's hand and stepped closer to the trench coat wearing angel. "We're just supposed to step back and let the people in the hospital die?"

"They're souls have been marked by dark and ancient magic," Castiel said, his steely eyes hard as he looked at her. "There is no way to reverse the spell." Dean's frown returned as he looked away from both Castiel and Allison and to the carpeted floor.

"Well, if we can't save them, then we can go after the witch that put the spell on them. Stop her from doing this again," Allison said.

"It is not that simple, Allison," Castiel said and Allison's retort died in throat as he said her name. They certainly hadn't been introduced, and the only reason she knew who he was because Dean had told her about him and Dean hadn't seen Castiel in weeks, so, he hadn't told him about her.

"It's Lilith, isn't it?" Dean suddenly asked, making both of them look at him. "This was a seal." Castiel's answer was a small nod in Dean's direction.

"Move on," Castiel said and Dean let out a frustrated sigh just as Sam and Addison walked in the room. Allison looked at Addison, whose smile slipped from her face when she saw the look on Allison's face. Allison heard a fluttering behind her and she turned around only to find Castiel gone and the four of them alone in the room.

"What the hell happened?" Sam asked and Dean scoffed before he shared a look with Allison and returned his eyes to his brother.

"You're going to want to sit down."
