AU-

Sam did his best to limp all the way from his room to the kitchen.

Sams throat was dry. He needed water. Damn, he needed a bath. It was yet another day of torment, but now he was growing used to it. He knew he couldn't get out of this trap, he knew he would have to stay his whole life long with a guy whose face was like Dean but he was not like Dean from the heart. A guy who was a monster himself called his brother monster. Sam stopped mid way at that thought. Who was he referring to the guy who was a monster himself as? Was it Dean or He?

Sam shook his head to remove the thoughts.

Whatever it was, he just wanted to have a bath. Changing into new clothes, Sam went to Bobby.

"Hi."Sam said bluntly.

"Oh, hey son. Where is..?"Bobby said as he looked up to see only sam and no Dean.

"i don't know."

Bobby nodded and Sam remained still. Observing a long awkward silence, Sam thought what if Bobby could help him out. He did try, but he needed more help.

"bobby?"

Bobby knew exactly what Sam would ask him. Who doesn't want relief from someone who was being cruel?

"No, son, nothing I'm blank. I think it's better if you start to ask Castiel for help."

As on cue, a flapping of wings sound told them Cass had come there.

"Sam."

"Cass, i need your-"

"So does Dean in the other world."

"Other...Cass take me."

"i can't"

That depressed Sam. He so wanted to go back. He was sick of staying with a guy impersonating - no wrongly impersonating- his brother

"Why can't you?"

"Because everything is not in my control, Sam"

Sam glared at Cass.

"But that does not stop me from helping you." Cass when said this Sam felt a tinge of hope inside him.

"What?"Sam asked, getting up from the seat and walking upto Castiel.

"You can trap Zachriach and force him to take you back. You can deal with him saying you will say yes to Lucifer. I will wipe your memory about it and his too about the same." Cass replied.

"Okay..that sounds good. lets get started." Sam rushed to the door but stopped when cass came in front of him,"There is one problem though." Sam sighed at this.

"The other Sam has to be inside a salt circle at the same time Zachriach thinks to swap you both. And if he isn't there. Well, you'll be just stuck in this world. Forever."

It seemed as if Sams breath stopped. But then he said, "Why don't you inform, Dean that?"

"It is difficult for me to come from the other world to here, it is against the rules, interfering with other angel's plans can kill me!"

Sam sighed at that.

He wanted to apologize to him but the angel was so pissed that he disappeared.

"Angel's a help. Come on, Sam, get started before Dean comes along."

SUPERNATURAL

Sam was drawing a sign behind the door, when Dean came in, his jacket slung over his hand, and a beer in his hand.

"What do you think you are doing?" He demanded.

Damn, Sam thought. He had to get rid of Dean, and that meant a combat, well it might be the last. It might be worth it.

Sam threw punch at Dean's face, as the elder Winchester's beer and jacket dropped down and he backed away in pain, "What the hell?" Sam knew this would turn out bloody, but he just kept going. Sam bent down and picked up the beer and smashed it at Dean's head. He fell down on his knees. He tried to get up, but Sam grabbed his arm and twisted it hard, till a breaking sound came along with a scream. Sam didn't want to do it, but he knew this wasn't Dean. Sam got ready for one last punch at his face, when Zachriach came from the back.

"Did you miss me?"

Sam turned to see Zachriach. zachraich looked at Dean with a disgusted look. With a snap of his fingers, the elder fake Winchester disappeared.

The angel turned back to Sam.

"So, Sammy, lets get on the business, shall we?" Zachriach said.

Sam patiently framed in his mind what to say and then began. "I want you to make me a deal. Its not about the souls, but, it can save many send me back to my own world."

"What do you benefit?"

"My yes for Lucifer, and i will convince Dean to say yes to Michael."

"You will do that?"

"yes."

"How can i believe you?"

"Don't. Your loss."

Zachriach let out a grunt. "Fine. I will send you back. But you know that the other Sam has to be inside a salt circle at the same time. Or else you stay over here, forever."

Sam nodded,"Yes."

"How have you managed that?"

"I am a Winchester. I can do anything."

Zachraich nodded.

REAL WORLD-

Dean paced around. Worried, he had just lost Zachriach and the worst nightmare was what he witnessed. He kept wondering what might be happening to his little brother when a bad thought stroke him. What if Sam doesn't survive that?What if that changes Sam's way of visualizing Dean as his brother?

No..That can't happen..Sam knows exactly how to differentiate, Dean told himself. But come on that was his little brother there.

FLASHBACK

"Dee?"

Dean looked up as he heard his name being called out in such a baby manner, but he smiled as he knew who it would be. "Yes, Sammyboy?"

"Dee, what is the color of a dragon?"

"What?" Dean asked as he sat up straight in bed.

"Yesh..I 'ean dragon.. Huuuggge.." Sam lengthened his arms trying yo show Dean how he huge, but in the process...he fell down.

Sam looked up. His brown looking straight into Dean's. Sam's eyes were big and innocent, but dean knew exactly how innocent his little brother was. The nine year old elder Winchester, couldn't resist a smile, but he forgot what came next. The brown eyes filled up in tears, and soon the silence was broken by the younger Winchester's crying.

"Oh, Sammy. Come here." Dean picked Sam up and put him in his lap and hugged him tight. Sam's face got dug into Dean's stomach and he could barely cry now. He struggled to break free and look at his elder brother's face.

"No. No, I'm not letting you go."

"Ee! Emm' o!" Sam tried to speak.

"You know, Sammy? I kind of never understood your baby language." Dean said sarcastically. Suddenly, Dean felt Sam relax and not struggle anymore. He pulled him apart to see if he was sleeping, but instead he got a small fist smacking him in the face.

"You i'iot!" Sammy yelled. Dean grabbed his hand and for one minute forgot that it was Sam and not some attacker. He twisted the little arm and received a pained scream from Sam.

"Oh Damn! Sammy I-" Dean started to apologize but Sam got down from his lap and went to a corner holding his hand.

Dean walked behind his little brother and stopped the moment he stopped in front of the T.V.

Sam climbed up on the rocking chair and sat there, his knees on his chest, and face dug in between the knees. he looked like a small kitten.

Dean pulled his face up. He saw the little boy's face was tear streaked and eyes puffy and red. Dean glanced at the hand and saw a red area.

"Sammy? I am sorry, i didn't mean to do it. You know I fight at school and it just got my habit, I forgot that you were my lil brother. I promise I would never hurt you again. Sorry."

Sam stopped crying. He tilted his face and bit his bottom lip. Dean knew exactly what that look was. Sammy was thinking deeply.

"Itsh k, Dee. I know you wo' hurmme. i know you di' 'ean it." Sam said at last.

Dean smiled and looked at the little hand, "Lets get this patched up?"

Sam nodded and Dean picked him up and went.

END OF THE FLASHBACK

Dean smiled at that memory. It was one of those that he loved. But that now that reminded that what Sam might be going through if he remembers this. Dean had promised to never hurt him. Forget about hurting, he was torturing the poor guy. Dean made up his mind. He had to do something. And he would get Sammy back no matter what.
