Daine rises to her feet and backs away a little, giving them room to work. She could get out and resume searching, but she'd rather see that Andrew gets himself sorted, first. Anyway, it sounds like recombining won't fix his leg, and if he does need a little help getting anywhere, she could take a sturdier shape.
