He'd truly, honestly forgotten, he had a child after he came back as a demon. It was the last thing on his mind. You were the last thing on his mind. Until Sam and Cas captured Dean and locked him into a room of the bunker, trying to make him human again.

It was the Mark of Cain. That's what brought the bad thoughts. What made him what he was. He'd died and came back as... a monster. That was the best way to describe it. But he felt free. Strong. Untouchable.

He'd drink. Party. Sleep around. Do work for Crowley. His girlfriend, aka you, and his five year old weren't even a second thought anymore... until he was locked up in that bunker and broke out, dark thoughts swirling through his mind as he attacked you and Sam.

His sadistic nature made knocking you and Sam out easy. Fun, even. His old self was still there in the back of his mind, screaming at him to stop... but he wasn't listening... until he heard a tiny, scared voice ring out.

"Daddy...?" A small, shaky voice spoke up, staring up at their father wide-eyed from the other side of the room as the bunker's sirens went off, and the lights flashed red.
