Visible crew/equipment: When the son of the accident victims is being led through the trauma rooms to see his parents' bodies, you can see Laura Innes crouching under a table in the background directing the scene. Innes was the director of this episode and it was established that this episode took place on her character's day off. Therefore, she should not have appeared in front of the camera at all. (00:32:30)
Continuity mistake: Luka is in talking to the first possible kidney transplant patient - he puts his pen into his pocket and is holding the chart in his other hand, also up by his chest. As he says "Minneapolis", the shot changes and we see him put his pen in his pocket again and his chart is down by his waist - there was no time for the shift.
Continuity mistake: When Louise is talking about her mother's Parkinson's, the camera shot from behind her shows her left arm folded up in front of her with something red over it - but the shot from the other side shows the red item draped over her right arm.
Continuity mistake: Near the end, when Elizabeth and her mother are having wine, in one shot her mother has put the glass down on the table, but in the next shot, from behind her, she has the glass in her hand again. There was no time for the change.
Be Patient - S6-E15
Continuity mistake: When Luka is accusing the man who hit the little girl, he places his hand on the guy's chest and says "and you just drove off - Hit and Run?"; the shot changes and his hand is off to the side, no where near the man's chest.
Continuity mistake: Mark and Dave are talking about the parachutist who had just died. As Dave says, "He died before I had a chance", an extra walks by them on the right. The shot shifts to Mark, who replies, but it is 4 seconds before the extra appears again beside Mark - this should have happened in a Split Second, not 4.
Continuity mistake: Dr. Romano hands Lucy a pen so that Valerie's mother can sign a consent form. Lucy puts her hand on the pen and then the shot changes and we see her put it on the pen again.
Continuity mistake: As Luka talks to the kidney patient, he is holding his chart to his chest. But several times during the scene, when the shot is on the patient, his hands are at his waist, but at other times they are folded in front of him.
Greene with Envy (a.k.a. Lawrence of Northwestern) - S6-E3

Be Patient - S6-E15
Continuity mistake: Near the end of the show, Mark is talking to his father, who is putting his bathrobe on; he has one arm in the sleeve but as Mark says, "I need to talk to you", his father turns towards him and the bathrobe is nowhere to be seen - a couple of seconds later he starts to put it on again.
Continuity mistake: When Carter picks up his crutches from the floor of the lounge, his hand is near the crossbars. When he hoists himself up, the shot shows his hand near the top of the crutches.
Continuity mistake: Near the beginning of the show, when Elizabeth and her mother are having tea before they both go off to work, for a couple of shots from in front of her, Elizabeth is holding the mug with both hands, but the shots from behind her show her holding it with one hand only.
Greene with Envy (a.k.a. Lawrence of Northwestern) - S6-E3
Continuity mistake: When Dr. Lawrence is working on the ER with Mark, he gets frustrated because the tag Kerry's issued to everyone gets in his way. He asks someone to get it out of his way, and as he moves around to the other side of the table, we can see it has been pulled up around the back of his neck. As he reaches the other side, it is suddenly hanging straight down again. A short time later it is tucked up around his neck again. At no time did he adjust it.
Continuity mistake: When Carter enters Mrs. Connelly's room, we should still be able to see Lucy who was just talking to him outside the door. But when the shot shows him entering the room, there is no sign of Lucy.
Revealing mistake: Near the beginning of the show, Mark's father puts a bulb into an old slide projector. Then there is a small explosion with smoke and flames - watched carefully, we can see are actually coming from the other side of the projector - the flames can be seen shooting parallel and close to the floor, which wouldn't have happened if the explosion actually came from the projector.
Continuity mistake: When Carol and Carter are discussing the overdose patient with nurse Dory, Carter's crutches change position and then return to their original position, even though no one adjusted them.

In the next shot, it's gone again.
Continuity mistake: When Carter leans his crutches against the lockers in the lounge, we can see two pictures taped to his locker. However, after he picks his stuff up off the floor, the pictures have mysteriously disappeared.
Continuity mistake: Near the start of the show, Dr. Dave asks the patient Jesse how he's feeling and Jesse answers, "Not so well", and then begins throwing up. By the next shot, though, there is more vomit on his shirt than could have possibly got there in such a short time.
Continuity mistake: When Dr. Finch is talking to Jeanie about the AIDS patient, Jeanie's stethoscope goes from being fully visible over both lapels to being only visible on the right side - without her touching it.
Answer: A man named Paul Sobriki comes into the ER in the season 6 episode 13 " All in the Family." He is complaining of headaches, Carter and Lucy decide to rule out meningitis and do a lumber puncture. Paul struggles during the procedure and believes that both doctors are stabbing him. Lucy, who is interested in Psych thinks something is wrong with their patient mentally, but Carter is dismissive of her. She gets cross with his attitude and she calls the psych department anyway to have a look at him. Later on and near the closing 20 minutes or so of the episode, all the staff start playing loud music and get a cake which appears to be blue lol, together to party as it's Valentines Day, Carter returns from somewhere and asks where Lucy is. He goes to check one of the rooms for her and Paul Sobriki comes up behind him in the dark and stabs him twice in the lower back, he collapses and as he falls unconscious he sees Lucy on the ground also. In the next episode, Be Still My Heart (ep 14), Dr Weaver discovers them and all of the staff work to try and save them, whilst Carter survives. Lucy's wounds are fatal and suffers a pulmonary embolism as Corday and Romano try to save her. Carter is grief stricken and feels guilty about the way he treated her, he becomes addicted to painkillers and Benton, Greene all help him and book him into rehab.
