Everyone believes they’re doing what they have to do, which sometimes means hurting others who are also trying to survive.

This episode fleshes out the world these characters inhabit, as well as the lives some of them have led. The key figure here is Isaac, the tracker who rescued Sara Holloway and her son Devin from certain death at the hands of the Mormon militia the Nauvoo Legion and their indigenous allies.

In this episode alone, for example, Sara, Isaac, Devin, and Two Moons trudge their way through blinding snows on horseback, until one goes lame and stomps Devin’s leg to smithereens in its distress after Isaac tries and fails to shoot it to death.
