Castiel thought that Kratos had made an effort to inform the rest of the patients that surgery was a viable, if dangerous, option. Apparently Lust hadn't seen those notes for herself, and while it certainly made him curious, he suspected that she wasn't searching for a cure for herself. He remembered how much of a toll those symptoms had taken (were still taking, in fact), and he couldn't see any of that on her face.

But just like that, she had invited him along. No discussion had been necessary, and Castiel preferred it that way. Maybe because neither of them had any need for human manners or customs, it was easier to cut to the chase.

"I will," he said after a pause, and before long he'd gotten into a rhythm with the crutches in order to follow her. It was going to be slow-going, but Lust was going to have to accept that.

"We need to keep on straight down this hall," he offered, because she'd seemed uncertain of where she was going earlier.
