Not to detrail the theory but the discription is:
Desperately in need... of some... strangers's hand.
Does this refer more to the coming phone call, where the groups of survivors need help from a 'stranger' (the other group)?
Or is this referring to the
Randy/
Michael situation, where Michael needed a stranger's, Randy's, hand to get unstuck back at
the water works?
Or is
Burt going to get a hand transplant?
