It doesn't escape her notice that he's looking at her, and it takes a lot of self control to not react in some way, but she does meet his gaze for a brief second, a silent warning in her expression not to comment on it. She isn't sure if he would or not, she doesn't know him well enough, but she feels the need to make sure he won't.

The fact they're joking around makes it easier, and she laughs at his comment, "Only mentally?" She quirks an eyebrow, amused that he's managed to wander into slightly dangerous territory by accident. Not that she'll mind either way as to what he answers, but - still.
