Dean has always had non-brotherly feelings for Sam but never did anything about it because he thought Sam didn't have the same feelings for him. Little did Dean know Sam also had non-brotherly feelings for Dean and hadn't done anything about it because Sam thought that Dean didn't feel that way about him. After Dean became a demon, most (95%) of his human humanity disappeared, but 5% remained and Dean knew he had to do something or he would become 100% demon, which would probably mean that hunters would come after him, and some or all of them would be killed. Dean remembered Cuthbert Sinclair's place and decided to go there. Somehow (how?) Dean found out that Sam has non-brotherly feelings for him, so he decides if he (Dean) is going to be locked away at Cuthbert's place for maybe eternity he wants Sam there as well (of course this is the 95% demon talking). Dean goes to the bunker and gets all kinds of stuff that he knows that Sam would want, and a few things that he wants. Dean knows Cuthbert's place is magic so he knows they can stay there forever and they will never age and never get sick. Dean sets up Cuthbert's place so that Sam can't leave unless he has Dean with. Dean then goes about getting Sam. How does Dean get Sam; get him back to Cuthbert's place and how does Dean convince Sam about their feelings for each other

Dean could feel the demon in him demanding blood, demanding him to find anyone or anything and slaughter them in cold blood. He almost gave in, almost. Except for that tiny human part of him, that annoyed him like nothing else the one that kept telling him it was wrong, not to do it, that all of his victims were humans that didn't deserve to die at the hands of a demon. Sure, he killed demons and a few monsters here and there but it never seemed to satisfy him, not like the way a human's death did.

There was just something about watching a soul, a human soul, die in agony. The way the soul cried out in fear and distress was like crack to Dean's dark, twisted soul. He just kept going back for one more hit. He took a shot of his drink and felt it burn down his throat. Alcohol didn't affect him like it used to; it pissed him off a little, now the only way to take the edge off was to kill. He left money and walked out of the bar.

Dean was walking towards the Impala when he heard a scream. He followed the screams and saw a man trying to rape a woman. He went up to the man to get him off the woman. He didn't care about the woman's cry for help. The only reason she isn't about to be assaulted was that Dean needed to kill and instead of killing an innocent person he'd rather kill an asshole that deserved it. (That stupid conscience also didn't let him kill the woman, anyway.) Dean got so much into killing and tearing the man apart piece by piece that he kept going on even after the man had died. Dean was on cloud nine.

He heard a whimper and still in a blood rage he went to attack the source of the sound. He stopped his tracks when he heard a scream of terror. '

"Please don't hurt me, please!", the woman yelled out, trembling.

Dean stopped short when he saw his reflection from the terrified woman's eyes. His eyes were completely black. A demon was staring back at him. He used to kill demons and protect innocent people from them. Now he was one. That thought jolted him back to reality. He was about to kill an innocent woman.

"Run," Dean ordered, "Run!"

The woman came to her senses and ran; it took every bit of Dean's self-control not to go after her. Dean stayed in place staring at the mutilated corpse of the would-be rapist. Dean had felt the exact moment the man had died, the way his soul had tried to stay in its body but unable to. The way the soul screamed out in terror and anger. Dean had loved it but right now his human side had suppressed his demon side.

Dean finally was able to snap himself out of it when he heard sirens. He couldn't stay or he might lose control completely and kill the officers. Dean jogged up to the Impala and drove away from the opposite direction of the sirens.

OoOoOoOo

Dean drove for a long time not noticing where he was going until he noticed the "Welcome to Lebanon, Kansas" sign. Apparently, he was heading home, or what used to be his home. He wondered if Sam was in the Bunker at the moment, trying to track down Dean even though Dean had left him a note to leave him be. With Sammy being so stubborn, Dean doubted it.

Thinking about Sam always brought about his non-brotherly feelings towards his younger brother. Ever since Sam had turned fifteen Dean had always viewed Sam in a sexual light. He knew it was wrong but he couldn't help it. He hid them from his dad, Sam, and sometimes even tried to hide those feelings to himself; it never worked out, though. There were times when he wanted to confess his feelings to his brother but Dean knew that Sam would never look at him that way and he didn't want to lose his brother just because of his fucked up way of looking at his brother.

Dean pulled off the side of the road. What was the matter with him? He shouldn't be going towards Sam, he should be going the opposite direction. Right now his human side was still in control but what if he snapped when he saw Sam. He knew that he could never kill Sam but didn't mean that he couldn't hurt him in other ways. What if he couldn't control his urges and raped Sam?

He should be finding a place to hide for the rest of his damned existence. Hide where no one would find him and where he could do the least damage. That's what Cain did and it had worked out for him until Dean had decided to fuck up his world. He could find a way to buy a house or a little cabin in the woods or maybe…

Dean jolted up, "Magnus."

Dean turned around and headed towards Cuthbert Sinclair's hidden mansion. He didn't need to buy anything. There was already a magically protected, invisible mansion in the middle of nowhere that Dean could hide in. He could live his whole damned life in that mansion with no one the wiser. Dean would only leave when he truly needed to kill and maybe find some evil humans to send to Hell. After all, just earlier he had confirmed that it didn't need to be innocent people he had to kill to soothe the demon in him. It could be any random sick, evil mother fucker.

Yes, Dean had a plan and Dean was about to set in motion. He smiled as he drove down the highway; he could do this.
