Joy Kringle - S3-E13
Continuity mistake: Right at the part where Joy Cringle is prepped for surgery and Christian says "Okay, ready to suck the pringles out of Mrs. Cringle?", there is a close-up of Joy's face. Although she should be completely out, it is real clear her eyelids flinch a few times.
Cherry Peck - S3-E14
Continuity mistake: After Sean and Christian open the 'bleeding package' and discover Kimber's implants inside, Christian notices a very very small piece of paper inside one of the implants with a message on it (so small that he had to put it under a microscope to read it). A few minutes later in the episode, however, he shows the piece of paper to Sean, and it is significantly larger in size.
Continuity mistake: At the climax of the episode when Quentin is revealed at the Carver, he has Sean and Christian tied up in their chairs and he cuts one of Sean's fingers off, of which Sean screams in pain. A few minutes later after Quentin is shot dead and officers/paramedics are assisting the scene, an overhead camera shot shows the entire area and floor around Sean's chair without any ounce of blood. Wouldn't there have been tons of blood from a finger being cut off?
