Now there's interesting.
She might have known he was here, but ... knowing isn't seeing (or sensing, or smelling...). It isn't hard to notice the modifications to his appearance, either - two Tribes' colours together... Even with the alliance going as it had, the idea is almost as disconcerting as anything else.

Still, he's a fellow Leader, regardless (no, this isn't the time to wonder if she still is one) and one who she can respect as such - so he gets a long polite nod. "Not long ago, as far as I can tell," she says.
