Plot hole: In the episode "10,000 Steps," the parents from Amy's case say they adopted their first son Daniel when he was 3 because they thought they couldn't have biological children. Howeve,r the birth of their other son Seth proved that theory wrong. But Daniel is 13 and Seth is 12, so when Daniel was 3, Seth would have been 2 already.
Continuity mistake: Episode 6-3: Ignacio pulls his keys from his pocket and shakes them in front of Maxine's face to distract her. He pulls the keys out and shakes them, his key fob (looks like a mini Swiss army knife) is loose and hanging down. The camera moves, he is now shaking the keys by the fob, and the camera moves again, the fob is back in the original position.
