Continuity mistake: Season 1, episode9, "Spy in the House of Love." As Dominic and Echo are fighting, Dominic performs a spinning kick which sends Echo into the air and down onto a table. The table breaks apart and Echo rolls off of a large piece of the table. There is a quick shot showing Dominic looking down at her, and then the shot returns to Echo with her head on that large piece of table.
Continuity mistake: Season 1, episode 8, "Needs." As Echo is holding a gun on Topher, in his room, the lights come back on, and Topher turns off his glow stick and throws it to the floor. Echo and Topher continue talking for a bit, and the next time the shot to the floor returns, the glow stick is not there.
Continuity mistake: "Season 1, Episode 7: Echoes." Topher is in front of his desk talking on the phone, while a kinetic moving toy is moving on his desk. Ms. Dewitt quits jumping on a trampoline and climbs over the railing. Take notice that as she climbs over the railing, the toy is no longer moving. However, when she starts to talk to Boyd on the phone and she and Topher are standing in front of the desk, the toy starts to move like it was first doing. Also, in that same scene, watch Boyd play a complicated piano piece without hardly using his fingers.
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.
