Blood, Sammy gone dark side part 2

Supernatural fan fic

Sam glared at his brother, slightly annoyed that dean had momentarily interrupted the symphony of screams. But he did again lighten Sams mood when he flinched after staring into his dark demon eyes. Dean didn't recognize what he was looking at. He saw his baby brother but the eyes belonged to someone else. Someone more sure of themselves, someone with more confidence and power.

Dean took a few steps back. He knew what his brother had done. He saw the evidence of it dripping down his chin to form a pool that slowly soaked itself into his T-shirt.

"Damn it Sammy, why?"

"Dean, Dean, Dean." Sam said slowly, taking a few short steps towards his brother. "How many times have I told you? Sammy is a chubby twelve year old. The names Sam."

Dean frowned, cocking his head slightly. Sam didn't sound right. There was an underlay to his voice. Almost like someone else was talking with him. He carefully slipped his hand into his back pocket and gripped the flask that resided there, Bobby's flask. Whipping it out (hehe) he splashed the holy water onto his brother.

Sam hisses and recoiled. Surprised at how the liquid burned him. He knew it was holy water. He could smell it. How, he had no idea but he was angered that his former brother had done that to him. He met deans eyes, his own flashing red in a moment of anger.

"I'm not possessed, Brother." He spat. " I have accepted this destiny. I need the demon blood and the demons need me. It only seems a fair trade."

"No. Sam... Just NO" Dean shook his head. "Don't do this. Don't let them take over. Sam lets just leave. Please. We can fight this together. We can get you help..."

"I don't need Your help." Sam stared down at his older sibling. He wanted to add more. Wanted to tell his brother how he had been holding him back, stopping him from reaching his full potential when he felt a tingling run up his spine.

He turned towards the far window to see a man in a black suit standing there, observing the scene. His salt and pepper hair stuck out at different angles, his worn T-shirt and jeans

"Lucifer..."
