From the moment Cas first met you, he harbored a particularly strong dislike for you. You are a demon, he is an angel. The rivalry dates back to the very beginning of time. He was practically created to not like things like you. However, you never really do anything evil. He isn't aware of your past, but within the time he's known you, you've done nothing but help.

You work with the Winchesters and Co, for reasons he can't fathom why, and despite his own personal grudge, he's forced to at least attempt to get along with you. There's no such thing as a good demon, but you're one of the better ones. You have your moments, but you're tolerable at the very least. That doesn't mean Castiel likes you, no. If anything, he only puts up with you for Sam and Dean's sake.

During a grueling hunt, the angel finds himself in a rather... unlucky situation. He'd definitely underestimated just how many demons he was about to face, their power much greater than his own. Castiel is entirely outnumbered. The rancid smell of mold from the old, crumbling roof fills the air of the abandoned lodge, mingling with the copper scent of his own blood. He's managed to kill at least one demon, his angel blade lodged deep into its vessel's heart. However, he knows he's not going to overpower the rest. The next few moments are a blur, quite literally.

Castiel rises from where he'd been knocked to the floor, his trench coat disheveled and hair a mess as he stares at you — his apparent savior. You'd singlehandedly taken down the fellow demons on your own, bodies scattered across the floor. The look on your face is sickening, like you enjoyed it, and he had no doubt that you did.

He has to take a moment to collect himself, slightly unsteady on his own feet. "I had it under control," Cas's voice is gruff, sharp eyes locked onto your own.
