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.
Revealing mistake: (Across Season 4) During several close-ups of baby Conor McNamara over various episodes in Season 4, you can see the off-colored slip-on "gloves" that are used to represent Conor's deformed hands.
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.
Other mistake: In episode 5-21: "Allegra Calderello," Allegra discusses with Shawn and Christian the fact that the show-within-a-show, "Hearts and Scalpels," featured a character based on her, called "pussy lips" because Allegra had her lips reconstructed with her labia. However, in episode 5-1: "Carly Summers," Shawn and Christian referred to their one-time patient as "pussy lips," but the network censors refused to air the word "pussy," and the euphemistic phrase "lady cha-cha" was used on the air instead. So Allegra would never have seen a character called "pussy lips."
Sophia Lopez - S1-E4
Continuity mistake: When Matt talks to the "fluffer", her lollipop disappears from her mouth in between shots. She then raises her arm and puts the lollipop back in her mouth. (00:20:35)
Sophia Lopez - S1-E4
Continuity mistake: When Christian talks to Matt outside the school, Matt hears the school bell ring and glances at the school and then back at Christian. In the next shot, he's facing the school and turns around to look at Christian again. (00:39:55)
Sophia Lopez - S1-E4
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.
Sophia Lopez - S1-E4
Continuity mistake: During the scene where Sean first meets Sophia Lopez in his office and he is about to counsel her, one camera view has Sean looking down at his notes and writing something, then looking up at Sophia as he begins speaking. A split second later, now from the opposite camera view, Sean looks up again and hasn't begun speaking yet.
Megan O'Hara - S1-E6
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: 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?
Audio problem: During the scene right after Julia was looking at Jude's photos and then is on the couch talking to him, pay close attention to the shots behind Jude. At least three different times, when Jude is talking to Julia about interning at her husband's office, we see Jude's lips moving but hear no words, or, he is speaking but his lips aren't moving at all.
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)
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: 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.
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)
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: 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.
Audio problem: During the scene where Sean goes to the doctor and they are trying to diagnose his shaking hand ('yip') condition. When the doctor and Sean stand up at the end of the consult, the doctor continues speaking to Sean, but his lips do not move.
Mrs. Grubman - S2-E4
Revealing mistake: Mrs. Grubman is lying in the coffin. She noticeably swallows when she is supposed to be dead.
Answer: It's a computer graphic.
