If you don't mind random strangers, Chrys is on the rescue team and would be willing to help him (if a little frustrated-reluctantly) get both his daughter and his Important Thing, if Asbel brought it up! He's a rookie gunner and not much of a combatant, but he can run and parkour out of a hot situation like nobody's business. He'll have the compound's layout and its secret passages memorized like the back of his hand, so it'd make searching faster, too.
