"I didn't even go near the contact stuff," Genma protested, and sniffed at himself. There was maybe the faintest tang of sweat, his laundry detergent, deodorant. A slight tobacco scent, but he hadn't had a cigarette all day, and she hadn't complained about his smoking before unless he was actively doing so. "I was working in the lab, yeah, but I had a coat and gloves on, and I washed up afterwards."

Now he was worried himself. Had he spilled something on himself and not realized it? Or maybe one of the fume hoods had leaked. He cleared his throat and coughed experimentally, relieved to find no sensations that warned of inhalant poisoning. Although he supposed if he'd managed to get into something he had an immunity to... But even those gave him a reaction, they just didn't kill him.

"Are you sure you're okay?" Tsume looked worn out, injured, and pissed off. Probably a Very Bad combination, Genma decided. "I really don't think I got anything on myself, I mean Aoshi didn't smell anything, and he'd have told me if there was a problem. So I'm pretty sure I'm clean. But maybe I should go change and shower, just to be safe."
