Continuity mistake: In the beginning of this episode, you see some religious cult members drive in to town, in a bus, and go in to a grocery store. While inside this store, an auto mechanic named Jesse starts bothering one of the cult members and pushes him in to a store display, knocking the display over. The very next shot you see the store display is upright.
Trivia: In Epitaph II: The Return, Alpha asks Tony, "Why would someone do something so horrible to that face?" He was speaking about the tech on Tony's face, but it was also a reference to season 1 when Alpha sliced up Tony's face with a knife.
