Plot hole: Kate in the Batcave says with absolute certainty "Alice doesn't know that Bruce Wayne is Batman. Whoever stole the gun, knew that Bruce had to have the suit to test it on." Both statements are leaps in logic with no foundation. Alice knows that Kate is Batwoman, and that Bruce's office is her center of operation (she even shines a bat-signal there!). It would be perfectly logical to assume that she made the connection. The testing bit is simply a non-sequitur; plenty of weapons can be made and tested on armor which fits the specifications, real or inferred, of a particular target, without being in possession of the item as a whole.

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: Jimmy was willing to give Cathy $10k in cash for her troubles and to help her out. She wanted to sell drugs instead of getting his charity. Now he's having a problem fronting her the same amount of money worth of drugs. He's saying his dealer will hurt him if he doesn't pay him back. Makes no sense how he had $10k to give her and now he needs her to pay back the $10k front of product he gave her. What happened to his $10k worth of charity? Why can't he use that to pay it off?
