Castiel wasn't feeling he'd found his place, he felt he'd been pulled from an urgent function and it didn't please him. He was stuck now worrying over little details that didn't matter or he didn't understand (usually both). His job was possible for him but he didn't see the point of it. He also had no idea about showmanship. He was blunt. He said what he saw and that's all. His "act" should have been a disaster but it would be saved over and over by the fact he was accurate. 100% of the time. It was surprising what people would forgive when he gave them just what they wanted after all- to hear something of themselves.
Outside of his job he had little to do. He investigated while they were there, how they were trapped, to no avail. He spoke to those he met but they didn't have answered either. He read the few books he could get his hands on and fiddled with his radio. He looked in vain for people he knew. For Sam and Dean. He would keep looking. Wouldn't stop until their possible lifespans were over and then maybe still. He hoped it wouldn't take that long. He was in their world now, his time in Heaven done again for now, and they were all he knew of this place so far.
Castiel wasn't looking for friends, for more responsibility, but he wasn't hiding away either. He was doing all he needed to do to understand his new situation. He couldn't do that alone in his trailer. He thought about finding the kitchen and asking if help was needed there. He had learned enough about the time he was in to understand that food was scarce and though he had very little experience of it he was determined to find some way to help those trapped with him.
The man coming the other way looked to be deep in thought but he was someone who Castiel hadn't spoken to, or seen, before. He made a point to try and check in with everyone there and so he had been making himself do what he tended to avoid and approach the stranger. "Are you newly arrived?" he asked, his tone mildly curious.
