It hadn't really been all that long since Castiel had arrived here in the first place -- a few short hours. After a complete moment of panic and loss of control in front of Anna (who shouldn't have been alive, he reminded himself), he'd eventually pleaded off company. He'd found a room, a bedroom, and sat there for a long while, right up until he couldn't handle staring at the walls in vague detachment anymore.
And anyway, something inside his stomach felt very oddly, and he was fairly certain he was dying. Humans, so fragile. Castiel wasn't certain at all how to handle that this was something that he just was now. According to the stabbing feelings in his abdomen though, he probably wouldn't have to live with much of anything much longer.
It was all very distracting. Distracting enough where he actually missed the fact that someone nearly walked directly into him. Cas stared for a long moment before letting his gaze drift to the wall, ceiling, floor. Anything. Clearly this woman knew him, and he wasn't certain how that worked.
"I--" He frowned, took a perfunctory step back because personal space - we've talked about this, Cas. "Am unsure."
