[He's not sure what hits him the most - if it's when their eyes meet directly again, or how he keeps his hand there, how the brush of his thumb sends shivers down his spine that all seem to convene into... something that isn't quite nervousness but almost feels like it, at the same time as it all is entirely too easy to fall into. But it all feels like it could threaten to bring him down in a way that Keith can't say he'd resist much.
Regardless, he's not sure he can find any words anyway, and doesn't try to speak when Shiro pauses to gather himself. Instead he moves his own hand to touch Shiro's wrist where his palm presses into Keith's shoulder. A reminder that it's okay, that he's here -- silent encouragement as much as it serves to maybe selfishly keep his touch there even a moment longer.]
