Continuity mistake: When Taffy, (aka, Echo) and her gang of thieves, blow up a wall that leads in to a high security building, huge amounts of debris lands in the hallway that they must walk on. As soon as they start to walk on that hallway, they become unhindered in their destination because there is not as much debris on the floor as we saw in the earlier shot.
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.
