Oh ho. Someone who agrees with Shigeki. Now that's rare.
While I honestly don't blame Sho for sticking with basic ethics here, I wouldn't go so far as to purposefully miss in a situation where the whole team would get pissed at me.
Or at least, if I were Sho, I'd tattle Shigeki for doing something that was objectively against the rules either way and baiting me into make such a decision so he could share more of flak. Which Sho didn't do.
EDIT: Whoops botched on a fact. been long since I last read that chapter. XP
