Continuity mistake: In her rooftop fight with Tommy, Batwoman opens with a batarang, then sends him face down kicking him from behind. They wrestle some, and the railgun goes off once. In a wide shot when she punches him in the midsection a few times while he is trapped in an armlock, you can see the gun on the ground. He had it in hand in the previous shot and is still in his possession later. (00:35:00)
Continuity mistake: In the lobby, Mary advances towards an injured woman she diagnoses from meters away. Seen from the front, she is holding her phone in the right hand. In the back view though, she has it in her left hand. The phone switches hand again when she commands the paramedics to go check her again. (00:32:45)
Continuity mistake: After some awkwardness in the elevator, Kate arrives at the party. Walks to the left and she comes across a blonde wearing blue pants and top. The woman holds her drink in her left hand, which becomes the right in the reverse shot. (00:20:30)
Continuity mistake: Tommy makes his unceremonious exit, and Kate spots Reagan. During the sequence with her, the same couple (she wears a reddish dress and has black hair in a ponytail) appears by the stretcher and then a few meters behind, even further behind when the camera is on Sophie reacting to her "There you are." (00:39:10)
Who Are You? - S1-E4
Continuity mistake: After the title screen, Sophie is reviewing Batwoman footage. First shot and two agents, one with a hat and one with blonde hair in a bun, walk behind her, right to left, met by another agent looking at something in her hands. Cut to the screen Sophie is looking at, and a few seconds later the same extras are doing their exact same walking routine starting from the exact spot. (00:01:25)
Who Are You? - S1-E4
Continuity mistake: In Bruce's office, the museum curator turns around to ask her assistant "Margot, is that the last lens change?" She initiates that line holding the handbag with her right hand, but in the reverse shot she is using that hand to point at her, since the purse instantly went under an armpit. (00:04:10)
Who Are You? - S1-E4
Continuity mistake: In the three-way meeting during the museum party, Sophie says "Sorry, I didn't realise you were here with anyone." A woman in a flower dress passes right behind her. Cut to Kate for awkward moments of silence, and back to Sophie, with the woman who did not make a millimeter of progress in her walk during that second. Even worse, seconds later when she says "You two have fun" the same woman is repeating the action from the beginning. (00:28:25)
Continuity mistake: In the orphanage fight, Kate at one point is pushed against a pillar by a villain who holds her against it. She grabs a fire extinguisher and smashes another guy in the jaw with it. She does not drop this weapon nor hits with it the villain who is holding her, but in the next shot she is just punching and elbowing him. (00:19:05)
Continuity mistake: In the elevator, Kate's dad is looking at the electric wires with a flashlight. His wife says "How can this city trust us to protect it", and he lowers the torch. Next shot, he has it still pointed at the circuitry, and he lowers it only a second later. (00:31:20)
Who Are You? - S1-E4
Continuity mistake: When Reagan and Kate have the break-up talk, Reagan catches her in a lie and says "You just said you were on a call." Behind her, a man with a conspicuous shirt (black with red drawings on it) walks off, and is in a following shot walking down the street, leaving for good. Right before she says "All I ask for is a little honesty", several seconds later, the funny shirted man is back behind her. (00:34:05)
Continuity mistake: At the university, Sophie ends up chasing away anyone interested in Mary. She motions her to go and in a close-up says "Kinda looking for my future husband here." Behind her, a woman with a bike is walking right to left. In the next shot, the woman is walking starting from a point much further back than before, and even more noticeably, two girls calmly make their way halfway through the stairs and sit down...but they were already sitting there in that previous shot. (00:12:50)
Who Are You? - S1-E4
Continuity mistake: When Reagan says "Sound like I have nothing to worry about" referring to Sophie, to the left of the frame a black couple meets a friend in a hug. In the next shot, they keep walking and Reagan says "I used to live there", passing by the same guy, not yet reached by the friend. (00:13:45)
Who Are You? - S1-E4
Continuity mistake: Magpie is trying to steal a Faberge egg. We see her lowering herself from the ceiling, a POV shot that positions her right in front of it and she makes the grabby hand gesture thingy like in her first heist. Batwoman throws a batarang, severing her cable and she falls on the floor, vertically. Nowhere near the jewelry case that was supposedly in her reach. (00:09:50)
Who Are You? - S1-E4
Continuity mistake: Somehow, Alice and a couple goons in conspicuous attire are just waiting by Catherine's car in the cemetery without her noticing. When she says "You know the thing I love about bad guys?" Elizabeth Anweis' hand is not in frame. Yet in the other shots you can see (use the jacket lapel as reference) that the hand, raised above the elbow level, should be visible. (00:06:20)
Who Are You? - S1-E4
Continuity mistake: Kate grabs her phone bedside, reading Luke Fox's message (complete with apropos bat-emoji). She puts it away and says "Sorry" to her fling, immediately placing the phone hand down her back, with the right hand being on her shoulder instead. New angle, and the hands switched position (left on shoulder, right hand at the middle of the back). After a few seconds of terrible lying, Reagan says "That sounds...really serious..." and you can also see a lot of hair moved in front of her shoulder. When they begin snogging before she goes there is more switching hand position business between cuts too, with the left hand being behind and in front. (00:02:30)
Who Are You? - S1-E4
Continuity mistake: Magpie tosses aside the cable severed by Batwoman's batarang. In two different overhead shots, the cable lies on the ground in two completely different ways. Even assuming during their fight they could have accidentally hit one end of it with the foot when it was not in frame, it still does not account for the massive difference. (00:10:00)
Continuity mistake: When Kate and Sophie are in the parking lot and Kate gives her the knife for analysis, she is holding the plastic bag in different ways between shots (you can see the ziplock of the bag change position, and her hands shift in the distance). (00:12:20)
Who Are You? - S1-E4
Continuity mistake: Kate is on her lunch date with Reagan. Panning shot of the Chicago aka Gotham street. There's a family with mom, dad and two kids, with a girl in purple that climbs up leaning on the railing, and her brother follows shortly. A closer angle follows ("Why the hell did you move back here", Reagan asks) and the two kids have yet to step to the railing, and do it in reverse order. Even more remarkable; at the very end of their long conversation, in the shot when Fox's message pops up, they are STILL by the same family despite the fact that they have been walking and passing several other people all along. (00:13:20)
Continuity mistake: At the beginning of the episode, Kate is sitting at Bruce's desk. In front of her as the camera closes in there's a newspaper, and it is slightly raised because it overlaps a packet of letters. A few seconds later Kate puts down the black card, and the newspaper, which she has not touched, is sitting perfectly horizontal on the desk. (00:02:10)
Who Are You? - S1-E4
Continuity mistake: In bed with the barista at the beginning of the episode, Kate puts her hand on her back. She says "I heard she's doing Batman" and Ruby Rose's hand is on her bare skin; reverse angle and you have the hand on the sheet that suddenly covers her. Next shot and the hand is on her neck, with hair rearranged accordingly. (00:01:50)
