1x03 While Visions of Safta Danced in His Head

The Hunters themselves are being hunted by the Nazis --- starting all the way back from episode 1. The hunting Nazi is a young American white supremacist recruit. And in this episode, this American Nazi shadows the Black female FBI agent in order to find the Hunters, and he ends up killing one of (teenager) Jonah's friends (Jonah's friend pretends to be Jonah in order to save him).

In the first episode the morality of killing a Nazi is taken for granted --- they are Nazis after all, and they act like one-dimensional evil cartoons. The second episode was meant to be (though it felt unconvincing) an exploration of the psychological difficulty of killing them --- even Nazis are human beings after all. This episode is supposed to provide the emotional weight to overcome any misgivings the characters (or the viewers) feel about killing Nazis: the audience is meant to feel the evilness of the Nazis, as exemplified by the murder of Jonah's friend, who is shown in this episode to be exceedingly virtuous in an every-day sort of way. Since episode two did not quite succeed, this third episode ends up feeling a bit contrived and manipulative.
