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)
Continuity mistake: In the Batcave, Kate holds the childhood picture with her sister by the sides in the first shot, by the bottom in the close-up. (00:08:40)
Continuity mistake: In her diary entry at the end of the episode, Kate puts the pen down to fetch the file. She puts the pen by the diary at first, but in the next shot the pen is on it, in the middle of the page. (00:40:20)
