A brothers bond was hard to break. Maybe they both kept secrets to protect each other. Sam wasn't willing to confess his sins and have Dean sacrifice himself for his own decisions. Dean use to be the one who arose the self-sacrificial routines. Now Sam had to protect him, not only from the truth, but from destiny itself. Evil was something that was growing in him according to Azazel. He didn't know where that line was drawn, where it would self-molded into destruction. He should be expecting the worse, and steer himself from all relationships. Even Buffy. He would of concluded that mission if she wasn't on Satan's list of souls to collect annually.
They were developing their own lives. It was different this time, cause Dean had his own, too. He never would imagine house ownership would fall into that category, but he was proud Dean invested in something longer-term - aside from hunting. Even a haunted house, which he could comprehend why Dean would find it amusing to invest in a home plagued by paranormal entities, still was a drastic change from a life that shies from normalcy. There was nothing more he wanted then a normal life. They both deserved a vacation from road traveling from town to town.
Cleveland, Ohio had potential. He could imagine himself living here, and the fact it was on a Hellmouth meant he could still fight evil and stay in one place. Now that he has been introduced to hundreds of slayers, he figured the weight of the world no longer laid on his shoulders. Even if there was something wrong with Sam, it didn't mean he couldn't try to gain something with Buffy. It wasn't like the slayer hadn't had her share of semi-evil men. Angel was a good example.
A shower of images rummaged through his mind. Hellhounds particularly, that caused him to frown at the idea of a relationship with a slayer again. She was a dead woman, and so far he couldn't sway the demons to break her contract or take his soul as a replacement. He had a feeling Azazel had something to do with this. Maybe if he found him he could convince him to release Buffy's contract. He couldn't bare to watch the woman he loved die and suffer eternity in the hell pits.
He lost too many people to demons and he wasn't about to lose another. It was easy around Buffy, which was something he didn't even share with Jessica. He always had to hide his past from her, and that had been difficult when she brought up questions on his family. Buffy he could be completely honest with her. He told her about his father, Azazel, and his brother. Every detail of his life, except the fact he could be going evil. He still was considering if that was true or a trick for him to join Azazel's army of freaks. He wanted answers, but he couldn't risk a moment alone of Azazel. He seen what he was capable of. If he were to strike he needed to do it discreetly.
Sam scrutinized his brother's expression, reading past the expressions and already knowing where this was going. A haunted house, indeed. Dean would never purchase a house without doing his background on it. Giggling children didn't sound threatening, and he'd imagined they were more of prankster ghosts then oppose the kind that had a thirst for blood. If those light bulbs kept bursting he may no longer have two eyes. He kept his arm shielded in front of his face, in case of any other accidents.
"Do you even need to ask that question, Sam? C'mon, man. You're getting rusty." He barely stared at his brother the moment another light busted in the kitchen. "Tell me why again you're living in a haunted house?" That would certainly scare off company. He couldn't imagine Dean bring any chicks in here without them fleeing out the front door the first five minutes.
