Most of the time, Lexie considers herself lucky (or something like it, anyway; it's not like she actually wishes ill on anyone) if she gets one patient during a clinic shift. Rare as that is, it's even more unexpected to find herself with one, or a potential one, before she even gets to the Compound. There's a half-second where, at the sight of Matt, she starts to smile, but then she takes in the whole picture, and immediately starts frowning in concern. For all she knows, it could be nothing, but it might not be, either, and at least she's well-suited for this sort of thing.

"Oh my God, Matt," she says, making her way to his side so she can fall into step beside him, at least while he's still walking. "Are you okay? What happened?"
