Shiro is very proud of Team A (and the rest of you too, but he's competitive SO.) He's very good at directing a team full of people, if he took a turn as the observer. He's also tall and would have a very good view up on his perch. His patience might have gotten a little frazzled if the team messed around at all, but other than that, he thinks this is a great challenge for his group.
He was also great for the teamwork in the floor is lava challenge but probably got distracted by the ridiculousness of this one. He absolutely did not pretend to burn up when he fell in so it was like :| face sinking beneath the surface.
