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.

Other: In the episode "Conor McNamara", Mrs. Grubman is lying in the coffin. She noticeably swallows when she is supposed to be dead.

Revealing: (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.

Continuity: 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.

Continuity: 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?

Revealing: 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: 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.

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.

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.

Continuity: 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: 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.

Continuity: 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.

Continuity: 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: 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?
