[Here's a voice you probably haven't heard in a minute- surprised enough by this day as it is, and even more so when the magenta light draws his attention and Keith turns to see Shiro there. It's a mix of relief, confusion and wondering if this is all in his head because he hasn't seen you in even longer than one would guess. And the sugary remnants on food on his clothes makes this all for a very odd experience.
He runs right your way, though, without another thought.]
