What Is And What Should Never Be.

A/N- Hey guys, sorry for the late update, my net's not being good with me. So..And thanks a lot for the reviews, favourites, and alerts. They mean a lot. Thanks! Enjoy! And yeah all wrong grammer and all are my faults. Don't blame a person. :)

Real world-

Two days. 48 hours. 2880 minutes. And-

Well that was too much for Dean Winchester's brain. He calculated the time Sam was away. Away with the evil Dean. This was pissing the elder brother. The talk with Bobby, well, that didn't turn out that sweet.

"But Bobby! Sammy has to come back! There is no way I am leaving him with that monster!" Dean yelled at the old man who wheeled to and fro between bookshelves trying to find a way to get the younger Winchester back.

"I am trying my best kid!" Bobby yelled back. Bobby hadn't slept since Sam was gone and asking Dean for a good night sleep was in vain.

"You—look Bobby, I need to have my brother back. He is all I have. And if he gets tortured by that bastard I will never forgive myself." Bobby looked up as Dean pleaded. Troubling Sam might be on Dean's routine but keeping him safe was his job. And it was Sam in the end for whom Dean was ready to give up anything and anyone. That's what had grabbed a portion in Bobby's heart the moment the two boys stood at the doorstep. Dean the over protective elder brother and Sam the shy and scrawny one hiding behind Dean's leg. Nothing had changed about their relationship. But well of course for Sam's behavior. He became more aggressive and more Dean- like. But hey! Hunting has its side effects.

"Dean I know you are worried sick but you think I am not? Sam's like my son and so are you. I will do anything to get him back, kid. Dontchya worry." Bobby came to Dean. Dean looked up and saw those father like eyes.

"I know, Bobby, its's just that….I am too tired..I'll get a shut eye."

Bobby knew that Dean didn't mean i-am-sleepy tired but he meant,"I am sick of this". Well Bobby couldn't blame them. It was really a hard life for the Winchester's. Come on, who gets motherless at the age of six months, get into hunting, lose their father and then the angels drag them into their chess game and use them as pawns? Bobby too engrossed in his thoughts, didn't see Sam come and grab a seat in front of him.

"Hey Bobby!" Bobby looked up in surprise,"Hey son!"

"What are you lookin' at?"

"Nothing"

The plain reply made Sam more eager to know what Bobby was ,looking at.

"Bobby can i help you out?"

"No kiddo. I am fine."

Sam looked around and then dragged a book that was Bobby eariler reading, to himself.

"I know you are not. You need my help. I will he-"

"NO Sam! I don't need your help!"

Sam looked at Bobby with those green puppy dog eyes, cracking Bobby's old heart.

"Look Sam, I am sorry, I shouldn't have said that. It's just that Dean's stressing me out. And I need sleep."

"Then sleep."

"Thanks son, but your brother will eat me alive if I try and sleep."

"Don't worry about that i will handle him." Sam said it with such confidence he knew none of it was coming to him when he was to confront his brother.

"Son, I know-"

"SON OF A BITCH!Where is my knife?! What is my revolver doing here?!"Dean yelled at the top of his voice.

Sam rushed to him.

"Hey Hey Dean.."

Dean turned to his brother. Fire flashing in his eyes. If looks could kill...

"Where-is-my-knife?!"

"I-Its in the bag." Sam managed to stutter out those four words. In other conditions he couldn't even have whispered.

"What the fucking hell is it doing there?! You know I like it under my pillow!"

"I thought you preferred your revolver now.. I am sorry Dean." Sam lowered his eyes.

Dean recalled that this wasn't the tough Sam. Not his Sam. Great. He just did an amazing job. That meant he had to...URGH..why him?!

"Look Sam I am sorry. I know i shouldn't have yelled at you. But...Umm.. listen I gotta tell you something, Sammy.."

Sammy...wow that felt so great to hear DEan say that to him again.

"What Dean...Is everything okay?"

"For a matter of fact - No"

"What? Why?"

"Sam i think you remember, when Dean was replaced by some good Dean? The good Dean is me Sam. I don't know how but my brother and you have exchanged places. And my brother is with that guy who tortured you Sam-"

Dean stopped as he saw a smile creep up Sam's lips.

"You are serious,Dean."

"Why wouldn't i? WHy-"

"I'M FREE FROM THAT MONSTER! YIPPEE!" Sam jumped up and down.

"Wait, you are happy?"

"Why wouldn't I? Course i am!"

"So wouldn't you go back?"

"Never."

Dean's worst fear came true. It felt as if someone had just punched him in the heart. Sam doesn't wanna go back. That mean's real- No that can't happen. Dean can't let Sam stuck with that monster.

Sam jumped and down and went out.

Dean flopped on the bed tears filling up his green eyes. He ran a hand through his hair and hug his face in his hands.

"C-cass?" Dean stuttered. Sobbing in his palms. "Cass? Listen up, wing guy, i need your help. Please open up your ears. Sam's in trouble. A big one. And i can't set it right. Cass help me man. If you don't help out, Sammy would kill himself. He's already gone through enough and this would be extreme. I may be hard on him at times, trouble him loads, say cruel words to him, fight with him, but still Sammy means a lot to me. Cass you are an angel, angles are supposed to know what a person are feeling...Mom told me, they-they find out what you are feeling, help you out of the problem, because that's what they do. Please Cass. I rarely pray and I need you to help me out. Please. Please. Please. Take care of Sammy. "

Dean looked up. Pale and tear streaked face. Bloodshot eyes searched for a guy in trench coat. But no luck.

Dean closed his eyes, and didn't know when he fell asleep.

AU-

Two days. One sprained wrist and eighteen cuts and many bruises. Well that's what was visible to Sam Winchester.

Bobby was not doing a crap about it, but he would try and tell Dean to stop. But Dean had a lot of ego. And Cass was not ready to help either.

Dean would be here any moment and Dean's phone was still not working. Dean's phone by mistake slipped in water, and well it wasn't good.

"It 'k kid?" Bobby asked.

"No. Bobby, it's not even close to okay."

Sam paced back and forth and Bobby felt sorry for the guy.

"Bobby, Dean will-"

"I AM BACK!" Dean announced.

"Damn damn Damn.." Sam cursed himself.

"My coffee, Bobby!"

"It's on the table Dean."

Dean expected Bobby to reply, but Sam did instead. Not saying a word Dean had his black coffee.

Just as he did he spat it out.

"IT"S COLD!" Dean yelled.

"I-"

"Sam..you.." Dean moved to him as Bobby wheeled out.

"Dean-"

"Don't Dean me!"

Dean pushed him on the bed. And punched him on the face.

"DEAN!"

Dean didn't stop and aimed for one more shot.

He kept on punching till something else caught his eye. His phone. Switched off. And wet.

"My phone." Dean said as he advanced to his mobile.

Sam started to walk back. When Dean threw the phone so hard on his face that Sam's nose bled. He doubled in pain. But Dean continued. He grabbed hold of Sam's wrist and yanked it behind his back smashing him in the wall.

"Dean please.."

"Dont' Dean me. You..You monster, i dont' know what to say to you."

Sam lost count of how many times he was smashed in the wall, punches, kneed in the stomach, or anything. But in the end. Sam knew his condition wasn't good. His nose was bleeding, he had a dislocated shoulder, black eye and god knows what else.

Dean had pushed him out. So, Sam was spending a night in one of Bobby's car.

He curled up in a ball and wept. Praying that his brother, real Dean, could come back.

"Cass? I know you and I aren't that good. But, please, Cass, help me out. I want my brother back. Explain me what's happening. Please Cass. PLease. I know i am a headache to Dean but i even know he wouldn't do this to me. Please Cass what's happening. You are supposed to help me figure out this problem. I might be Lucifer's vessel, but that doesn't stop you from helping me and Dean, does it? PLease. If not for me at least for Dean. I know he would break if he gets to know what's happening to me. I don't want that to happen to him. Please Castiel. Help me out. Take me through this.. PLease.."

At first Sam thought Cass might help him out that very moment but he was wrong. No wing flapping sound. No guy in trench coat. He was alone in the car. With himself and some good memories. Maybe that might take him through the night. Maybe. And maybe Dean might be okay tomorrow. That too was a maybe.

Sam closed his eyes and fell asleep thinking of the good times he and Dean had together.

A/N- sorry for the delay. Hope you like it. REVIEW REVIEW REVIEW!
