”I learned my lesson in heaven. I don’t serve man, and I definitely don’t serve /you\”

Castiel knew it was wrong the second the words spilled out of his mouth. He didn’t believe in the words, especially not to you. You meant everything to him. Ever since he’d saved Dean from hell and had stuck with you and the Winchesters, you’d always been his favorite. Though, he wasn’t very fond of the reality of being attached to a human.

Neither did heaven. Heaven had tortured him for days. Belittling him because of how close he’d gotten. But, it still wasn’t enough to get rid of the attachment. Honestly? It had only gotten worse. His attachment you was strong. No amount of torture would break that.

After a few days of silence from the angel, he finally showed back up. Mostly to talk to Dean, but he had to say something to you as well.

“Hello. How have you been?” Castiel said to you, his voice was still the same as it always has been. Deep and emotionless. Same Castiel. Just, colder. Harsher.

It was as if he was an entirely new angel. Yet, something about him felt the exact same.
