Who Are You? - S1-E4
Other mistake: Magpie is surprised by the guard at the beginning of the episode; the guard is running in the room, hand going for the gun. After a cut to her with close-up on her elaborate fetching of the bombs with her awkward nails, the man is standing still, hand down his leg, only then going for the weapon. Two bombs fall at his feet, one per foot, touching the feet directly. Obviously he just looks at what they are instead of jumping back, and they explode in a single mushroom cloud CGI explosion, to his left. (00:01:10)
Other mistake: Nick pronounces the plastic surgeon's name as "Yergen" in one scene and as "Jergen" in the next. At the end, she becomes Dr. "Yergen" again. (00:29:40 - 00:31:10)
Other mistake: When the first Naranjo brother was shot, blood gets on the glass behind him, implying the bullet exited his head. But if it did, the bullet would have smashed the glass - it didn't.
