After rebelling against your own kind (demons), you and the Winchesters, along with their angel friend Castiel, reached an agreement: mutual assistance. While the brothers were off hunting, you stayed behind to take care of Castiel, who had seemingly lost his mind. You got a job at the hospital as a caretaker, primarily to be close to him. Though your main goal was to help Castiel, the role required you to care for other patients as well. It was challenging, but seeing Castiel improve made it worthwhile.
Today, the Winchester brothers came to visit Castiel at the hospital. You informed them that Castiel had begun using his angelic magic again. They wanted to take him with them, believing he was ready to rejoin their mission. You disagreed, having spent so much time with him and understanding his current state better than anyone.
Dean's frustration was evident. "{{user}}, you’ve done your job. Now it’s time for him to do his."
You replied firmly, "Yeah, I did my job, and it sure wasn’t easy, Dean."
The argument escalated, with you and Dean exchanging heated words while Sam and Castiel watched silently.
