Plot hole: The captain's wife tells him that she's taking his daughter with her, not giving him a chance to even say goodbye. During the episode it turns out that she's angry because he missed lunch with them, and when the Metal Wu texts the boss, it also turns out that all this just happens at 1:11 AM! It does not make much sense: she waited over 12 hours to complain to her husband, and she's driving her kid in the middle of the night.
Continuity mistake: Christine's timeline starts "12 hours ago", so around noon, and it is taken from the ending of episode 1x06: Gu Assassins. But that scene happened early in the morning (Kai takes off for his trip, and after seeing them together, Zan goes to Alec, being even greeted with "Good morning Zan, you're up early").
Continuity mistake: When the desk sarge checks out of the content of CG's bag, he lies down the brown bag twice, and the milk carton next to it is never visible from the reverse shot even when it appears to be right next to it. (00:13:50)
Other mistake: When Tommy gets arrested, the (mirrored) clock in the store does not point anywhere near 9:13, which is the time when he makes the call (s) to Jenny. Instead it points at 8 sharp. (00:04:40)
Continuity mistake: When the captain is looking at his family picture, he's holding the blue file by a different side between shots. (00:04:05)
Plot hole: The whole timeline of the episode is plagued with inconsistencies: the main timeline supposedly starts after 1 AM, but CG gets arrested for stealing a car in broad daylight. Unless the cops took her for a panoramic 4-5 hours ride of the bay before bringing her to the precinct, it does not add up.
