Gu Assassins - S1-E6
Continuity mistake: When we see the outcome of the fight between Jenny and Zan, Zan's very last move is a low spinning sweep kick. When Jenny lands, we see she has a cut above her left eyebrow, but nothing particularly significant. However in her next shot she's a crimson mask with that wound wider, blood that gushed down that cheek. (00:34:40)
Gu Assassins - S1-E6
Other mistake: The clock behind McCullough signals 5:10, and he wishes "Good morning" to Zan. It's way too early for the sun to be up. (00:42:40)
Gu Assassins - S1-E6
Continuity mistake: When at the end of the episode Zan meets McCullough, he has the fingers of both hands entwined when shot from the front, but always just a solitary resting left hand in the reverse angle. (00:43:00)
Continuity mistake: In one shot (the one where the racist waitress slowly puts her hands on her hips), the sausage platter is turned differently than in the rest of the scene. The same mistake pops back later when father and son are confronted by the couple of white knights. (00:18:10)
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)
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 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)
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.
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.
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").
Paths Pt. 1 - S1-E9
Continuity mistake: When the man in Croatia 'drowns', in the closeup one cigar butt (at least one) is missing from the ashtray, and a pile of coins appears. (00:03:20)
Paths Pt. 2 - S1-E10
Plot hole: When Alec goes back in time to his family, there is no sign of his younger self before becoming a Wu Assassin.
