Hey Gentlemen, I hope I can provide some insight. I have a couple of good friends, and coworkers whom are Mormon ( no, I don't subscribe to that faith), and from my understanding, they and their local temple, or chapter, have already established an egress plan in the event a situation arises. He's probably already allocated to a group as far as a resource goes, so even if you offered he may decline. It might be worth while to discuss your egress/or lack there of (while marinating op sec of course) with him and gather some Intel as to what his plans may be, you never know, maybe hes thought of something you haven't or vis-versa. Good luck with your endeavors regarding this matter, and I hope this helped.
