It's awfully off-putting to have someone say, 'YOU.' It's doubly off-putting when you don't know who they are. That means that, somehow, someone knows something about you - that somehow, you've got a reputation or something. And Kitty doesn't have any desire to have any sort of reputation, but she especially doesn't want one that makes someone go, 'YOU.' Maybe one that makes people go, 'Oh, wow, you're Kitty Jones, I never thought I'd meet you, if it's not imposing too much could we sit and talk a bit about right and wrong?' That'd be an all right reputation - one she wouldn't mind so much. But 'YOU' isn't good for anyone or anything.

So Kitty's grip loosens a bit, from confusion and alarm. Until she realizes, or maybe this kid is just saying that to throw you off-balance, and then she goes to grab him again. "Turn out your pockets," she blusters, trying to cover for the fact that she is off-balance.

(Does she know him? There's an odd something in the back of her mind, some little prickle of recognition...Have they run into each other in Kirkwall before?)
