Why he's here when he has no interest in actually socializing isn't something Castiel has spent very much time trying to evaluate. The bright lights and the loud music keeps his mind off of what little information he's gathered about Medietas. Enough, that at least he can rest. He might not need it necessarily, not the way someone else would, but given the course of the past several months, he's taking the brief moment to himself with no guilt.

Seeing people move to the rhythm reminds him only vaguely of Hannah, and he wonders how she might be doing. Heaven was still in a state of disrepair, a broken thing compared to what it had originated as. He knew he was responsible for reducing it to that.

When the song slows Castiel pulls his leg forward toward the couch, preparing himself for a long walk back to the rooms. In the process, he trips someone making their way through toward the bar and food behind him and away from the crowd. His immediate reaction is to reach out and try to steady them.
