[Maybe it's not immediately obvious, what with everyone acting a little odd today, that something isn't quite right with Shiro. Well, there's the obvious changes-- white hair, a blatantly missing right arm-- but he seems a little sleepier, a little slower in his movements and attention. He hasn't been missing from the island long, but it's certainly been longer for him.
Everything in his head's all rattling around and uncentered; it's difficult for him to make sense of what's just happened, on top of receiving "his" memories of this place.
He hasn't lost any feelings, in this case, but-- well. He's overwhelmed. And he looks it, too. Usually he has a bit more of a poker face than this, but it's clear that whatever's happened to him was a lot. Even moreso that he keeps starting to walk in a particular direction and then stops, as if he isn't actually sure where he's going.]
