Continuity mistake: Around the middle of the episode, Charlie Eppes and Mildred French are discussing in front of a board. She completes an equation and he adds a minus. In the next close shots, the minus disappears and reappears with angle changes. After three or four changes, a circle appears around the minus.
Continuity mistake: "The Art of Reckoning": At the end when Lucy and Pony are at the table, she extends her left hand and he lays his head on her hand. In the next shot, he is holding her right hand with his head up and then in the next shot he is back to lying on her left hand.
Continuity mistake: While Charlie is talking to Dr. York on the phone, the camera is at a wide shot, notice that Larry's name tag is not behind Amita on the wall. When the camera cuts to single shot of Amita, Larry's name tag appears on the wall. Then, the camera cuts to a wide shot again, and the name tag disappears.
Continuity mistake: When Charlie is in his office talking to Larry, while going over the potential killers and victims, he writes the word "Killers" on the board and circles it. Then, when Charlie notices that Larry has left and says "gone", the writing is different. The 'k' is wider, and most noticeably, the left side of the circle is gone, and the loop in his 's' disappears. Once Charlie goes back to working, the word changes back to how it was originally written.
Continuity mistake: When the FBI goes to arrest Tabakien, his men try to stop them and Don slams one of the guys' heads into a plate. The plate breaks into several pieces spreading the food all over. After you see the other men being stopped, you see a shot of the first guy again. And you can see that the plate is mostly intact and the food is not spread around as much.
Revealing mistake: When Crystal sets fire to the meth lab, she flings her lighter in a straight direction towards the front door. But you can see that the fire does not start there: it starts in the middle of the front porch, more than three feet from where her lighter landed.
Continuity mistake: When Amita talks to Charlie that she isn't quitting the running of curriculum and he's writing something on the board- he is holding a laptop entering something in it, than camera shows Amita and when it comes back to Charlie- there is nothing on the laptop screen (only black screen).
