Fire Chicken - S1-E3
Plot hole: Unable to locate "the bald chef", Uncle Six orders his men to bring him all the bald chefs of Chinatown. And they do! His goons round them all up, in a single sweep. They fit in a little van. So...in the whole San Francisco Chinatown, over 30,000 inhabitants, there are only literally a dozen bald (or balding or shaven, when you look at who they got) guys working in a kitchen.
Plot hole: CG is worried that if Kai phones her, he might blow her cover. Kai is no suspicious character and it's established that they know each other after the windshield errand. On the other hand, she engaged in a fight with several thugs and the very boss of the Triad who all have seen her, her cover should be pretty much blown already at that point. It's also quite funny how she made sure to meet with the Captain in secluded locations during long jogs, but then kept in her desk police files about the suspects! Some undercover cop.
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.
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.
