A/N: Set pre-series I think. Dean's a demon, not possessed, but he still loves Sam unconditionally. Some things just can't be burned out of a soul.

Summary: Dean won't let Sam get hurt and he won't let anyone separate them. Demon!Dean snippet.

I've Got You

"Dean, let him go. Please…don't hurt dad."

"He's in the way, Sam! He'll only try and get between us."

Sam's tear-filled eyes stared into his big brother's.

"Please, Dean…for me?"

Dean looked at Sam for a while, eventually, his features softened and he resumed stroking his thumb over Sam's cheek.

"Alright, Sammy. For you." Behind him, John stopped gasping, but was still held to the wall. "But if he comes after us, I can't promise anything, alright?"

Sam nodded and Dean turned to gaze hard at John.

"You hear that, old man? You come anywhere near me or Sam and you're dead before you hit the floor."

After making sure John understood the warning, Dean flung the hunter back, knocking him out. Sam jumped, but didn't yell, didn't open his eyes. Dean turned back to him.

"See, Sammy? Everything's okay. I'll never let anything hurt you."

Sam managed not to sob when he opened his mouth, staring into his brother's unearthly green eyes, looking at him with real love and trust.

"I know, Dean. I know."
