The Agent Of Year Zero - S4-E14
Revealing mistake: During the scene when Mr. Lyle is talking to the General (butcher character), his glove that he wears on his hand is removed to make a point about his thumb having been cut off. In the next shot, we see Mr. Lyle walking around the desk and putting his glove back on, and you can see his thumb folded under his hand as if the actor was trying to hide it and did not realize it could been seen from the camera angle.
Revealing mistake: Throughout the entire series there is one staircase upstairs and two downstairs. And, they more than likely are not the same staircase because the two downstairs are on opposite ends of the house.

Also the background sounds from the club - the music, people talking, etc, are missing.

Star Crossed - S1-E6
Revealing mistake: About twenty minutes into the episode, Tru sits down next to Jen. Jen says, "I saw you in line in the cafeteria." Tru, with her hands at her sides, says, "Tru." Jen says, "Jen," and raises her hand to shake, at which point Tru reciprocates. But how did Jen know that Tru was introducing herself? After all, pretty much nobody else is named Tru, so in context it would have sounded like Tru was saying, "True," as in, "True; you did see me in the cafeteria."
