"Well, with the way things work around here I'm sure it'll happen, and at the worst time," Sherlock smirked as he lifted his fork and took another bite of his food.

Still, as curmudgeonly as Sherlock was, he actually did like it when people didn't run away screaming from him--and that was before the scales thing. He immediately appreciated any kindness from other people (and at least people that weren't his brother.) He'd been bullied relentlessly and treated poorly for his abilities, and his rudeness and brutal honestly, so being treated kindly, even after being rude, was out of the ordinary for him.

"Good to meet you too." An actual, real smile. Pretty rare as such things went.
