15, any ethnicity, he/him, wary and young.

Joshua is a teenage boy found on the trail in Idaho, fleeing raiders who killed his trapper father. His mother died before the collapse. He is cautious, underfed, and speaks only when spoken to — until he doesn't. He rides with the group briefly, begins to open up to Liv, and dies protecting her from a grizzly bear at a creek crossing.
