Sam walked into the dark motel room, the only light coming from the dim lamp in the corner. He immediately pulled his gun as he walked inside, seeing someone was standing in the middle of the room facing away from him. "Don't move." He warned, pointing his gun towards the shadow. They stopped and held up their arms. "Alright, turn around." He said, realising there was no immediate threat and moving to turn on the light. As he turned it on his arm dropped to his side, his mouth hanging open as Kate turned to face him.

"Hey Sam." She said casually.

"Kate.." He stared at her in complete shock for a minute before holding out a knife. "You know I've gotta check you're you." He told her quietly.

She smiled at him and pulled out a knife. "Let me save you the trouble." She ran the knife over her arm and put it down on the table. She then picked up a bottle of holy water, pouring it over the cut, smiling at him when nothing happened. He took a step towards her and pulled her into a tight hug, she barely hugged him back before pulling away. He looked over her carefully, something seemed different to him. She even looked different. Like her usual calm face seemed cold and hard.

They both turned to the door as Dean walked into the room, stopping dead in his tracks when he saw her. "Kate?" He looked over at Sam who nodded at him.

"Hey Dean." He walked over to her and pulled her into a hug, getting nothing more than a small pat on the back before she pulled away.

He looked over her, the shock still clear on his face. "Are you alright?"

"Never better."

Dean looked over at Sam who shrugged at him, looking as confused as he did. "How'd you manage to bust out?" He asked her curiously.

"I dunno." She answered simply.

"You wanna try that again?" Dean asked her. "This time without the lying."

She turned to stand in front of him, narrowing her eyes. "Who says I'm lying?"

"I do. I mean you obviously know something or the first words out of your mouth would have been to ask us how we got you out."

"Maybe I'm just so happy to see you it slipped my mind." She mumbled sarcastically.

"What was that?" He asked, raising his eyebrows.

"Nothing." They both looked up at her as her phone rang from her back pocket. She pulled it out and looked at it before shoving it into her jacket pocket. "I've gotta nip out. I'll be back later." She said flatly, walking between them and slamming the door on her way out.

"What.." Dean shook his head. "What the hell was that about?"

"Search me."

He looked at him seriously. "Something's not right."

"She's her Dean. I checked her, silver knife, holy water.."

"C'mon Sam, that wasn't Kate."

"Look, I know she was acting kinda weird-"

"Weird?" He raised his eyebrows. "I'd say major bitch is the way to go."

"Dean-"

"I mean, after a month in hell I expected a hug or at least a 'hey how ya doin', not her to be back ten minutes and then bail."

"Dean, I bet you she remembers it. She's probably still trying to work through it."

"Sam, you know that wasn't her."

"Or maybe it was.. and maybe she's just.. different." Dean looked away from him. That freaked him out even more. The only thing worse than some creature coming back as her was her coming back bad.

Kate came back a few hours later with blood on her shirt and jeans, and from what Dean could tell, it wasn't hers. "What the hell happened to you?" He demanded, looking her up and down quickly.

"Nothing important." She muttered. "Where's Sam?"

"Store." He said simply, turning away from her and continuing to shove his stuff into his bag. He turned quickly when he heard the sound of a gun being cocked behind him. He ducked to the side as Kate fired the gun, just managing to move enough for the bullet to him the wall right beside his face. "What the hell was that?!" He yelled. "You nearly shot me in the freaking head!"

She smiled slightly and shrugged. "My bad."

"Your bad?!" He looked at her, his mouth hanging open, suddenly feeling a sense of relief as they heard the Impala pull up outside. He could see it on her face, somewhere he could tell that she knew she was busted. He turned from the door back to her, being met with a hard punch to the face before she moved quickly to the door and left before Sam came in.

Sam walked into the room to find Dean with a hand to his face, attempting to stop the blood flowing from his nose. "What the hell happened to you?" He asked, quickly crossing the room to him.

"She tried to shoot me in the friggin' head Sam."

"What?" He handed him a couple of tissues to try and stop the blood.

"She pointed a gun at my head and fired." He said simply, pointing to the bullet still stuck in the wall.

"Why would she want to do that?"

"Because she's not her!" He yelled, walking towards the bathroom.

Sam sighed heavily. "We'll talk to her."

"You wanna talk to her? What part of she's trying to kill us don't you understand?!" His face softened slightly as he stood in the doorway and looked at him. "You know that's not her. I know you don't want to accept it but deep down you know, that's not your sister Sam."

Sam looked down and nodded. He did know it wasn't her. And Dean was right, truth was he just didn't want to accept it, but he knew that he'd have to. And that they would have to do something about it before someone, most likely one of them, got hurt.
