[Jean is well aware of Ayato's reservations about being in the Autumn Segment. He's ready to do what he can to help him if it's needed so they can make it back safely. Even if the situation wouldn't look dangerous to him, he'd still act if Ayato panicked.

Jean's been on this quest before with a different person, so he knows what to expect, at least.]
