Visible crew/equipment: When Christian and Merrill are getting ready to watch the fights at Christian's home; just after Christian hands over the remote and stands to go change you can see part of a crew member standing behind his chair on the right of the screen. (00:09:40)
Factual error: (Season 4) During the episode where Ms. Grubman and Christian are talking in his office and he turns around a few seconds later to see she had died while in her wheelchair, her head and posture is still straight up and forward - near impossible. Common physics tells us that upon death, her head would have either drooped backward, downward, or to one of her sides.
Continuity mistake: As Christian and Sean are consulting with Megan O'Hara and her husband, you can see a clear shot of the clipboard of her file, and her age states 31 years old. About a month later, Megan dies (Adelle Coffin episode) and after the funeral while Julia and Sean are in an argument concerning his affair with Megan, Julia expresses remorse that Megan died at 36 years old.
Plot hole: Towards the end of the episode, Mr. Alderman ties up Cherry Peck and forces Matt to cut off Cherry's male genetalia. Matt does so, and Cherry screams in pain. Later on that night (probably at least an hour later in what would be "real time"), Mr. Alderman and Matt drive to a secluded area and Mr. Alderman forces Matt to bury Cherry alive. Matt refuses, and Cherry eventually steps out of the grave and strikes Mr. Alderman with a shovel before shooting him. Cherry has the same clothes on, but is in no sign of pain, or is even bloodied from the earlier trauma. It is safe to assume that neither Matt nor especially Mr. Alderman would have driven Cherry to any hospital, nor would any hospital even have let her out in an hour or two's time after an injury like that.
Continuity mistake: During the scene where "Fluffer girl" is talking to Matt explaining she has the clap, in one camera angle Matt is seen next to her slowly stroking her back with his hand in a caring and concerned matter. Not even a split second later or two words further in her sentence, a different camera angle now shows Matt with his hands out in front of him on his lap.
Revealing mistake: As Dr. McNamara is marking Megan O'Hara for her breast reconstruction surgery you can see the lower line of her prosthetic "removed breast" from her mastectomy on her left side. It is not the surgical scar from removing the breast, that is visible about an two inches higher closer to where the nipple should be. My aunt had a mastectomy, I know there should be no scar here.
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: Just as the episode starts, Dr. Troy is reattaching a thumb and some fingers to a patient. Liz then tells Dr. Troy that he incorrectly placed the middle (longer) finger where the index finger should be. As she says this, the camera shot of the hand from a few feet away shows that the fingers ARE correct, then the following close-up show shows the fingers attached wrong, not to mention if you look real close during this shot, the fingers flinch a little.
Continuity mistake: When Matt and Henry are driving after getting high, they accidentally hit Cara Fitzgerald with Henry's car. Matt then slams on the brakes, and you can see black skid marks. After the car stops and they get out to look around, several different camera angles show no skid marks at all behind the car now.
Continuity mistake: During the scene where Sean and Megan are talking on the bench after abruptly leaving the restaurant, pay attention to Sean's arm as it is around Megan. It changes positions several times around Megan's back and shoulders during different camera angles, and he never noticebly moved it.
Plot hole: At the end of the episode when Dr. Troy is trying to get Father Shannon to confess to raping the boys, he eventually sticks a scalpel in Father Shannon's thigh, causing bleeding and ultimately making him confess via immense pain. A few minutes later, we see Father Shannon kneeling at the altar repenting/praying his final goodbyes before being escorted away by the police. We see no evidence of pain or blood, etc. Finally, Father Shannon's crimes aside, wouldn't Dr. Troy have been in some form of trouble himself for stabbing somebody?
Deliberate mistake: While Megan O'Hara is undergoing breast reconstruction surgery, as the camera pans a close-up side angle view of her face you can see she is wearing make-up, specifically eye make-up, which is strictly prohibited in a surgical sterile environment in the United States, especially in pre-scheduled surgeries. (00:23:50)
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?
Other mistake: (Season 4, Episode 1) During the scene where the phone sex operator lady is having her voicebox operated on, you can see on at least three different occasions her eyes flinch and squint. Obviously, she was "awake" when this was filmed, but during a normal procedure such as this, she should be completely sedated and she would not be flinching her eyes.
Continuity mistake: In the 5th season, episode 15, Christian is supposed to have several bruises and a broken clavicle, so he is wearing an arm sling when he is talking to Sean. After Colleen attacks Sean and locks them (Sean and her)in the office, Christian pushes the door. and when he finally opens it, sees Sean on the floor almost dead, In this scene he is not wearing the sling, and is moving the arm perfectly (when he's supposed to have a broken bone) and there are no bruises.
