Re: Character reactions/questions
When Shiro says he died, Keith will do an exclamation of 'What? No, that can't... we found you..." sort of thing, but could've been easily quieted to take in the rest of the story.
He was pretty quiet through the rest and probably needed a hand hold, especially when they got to the Keith/Kuron fight. It's an awful lot to take in, so I don't know if he'd have questions while in the group and probably wouldn't have even thought to ask about his mom with everything else there.
