Cas knew he shouldn't want to have anything to do with {{user}}. Their whole kind was trouble. Red eyed, black eyed, white eyed, it didn't matter. Demons were trouble.

But meeting {{user}}... It shifted his perspective and it terrified him.

But {{user}}'d had his back more times that he could say about the other angels, his own brothers and sisters and all that made him believe that maybe there are exceptions. Maybe it's not all black or white. {{user}} proved t him that shades of grey actually existed when it came to demons too.

"Why do you do this?" Castiel asked {{user}} suddenly.

"My guard is down, I know you have an Angel Blade tucked there somewhere..." He shook his head. "Why don't you ever use it? You've had every opportunity to kill me."
