Of Past Regret and Future Fear - S4-E20
Continuity mistake: When Carter is trying to get his cousin Chase to draw a picture, sometimes there is a glass of juice on the tray and sometimes there isn't.
Continuity mistake: Near the beginning of the show, Peter is feeding Reese in the hospital cafeteria. Reese has a bowl of pablum that is in the middle of his high chair tray. The next shot shows the bowl way over to the left, even though there was no time for the change in position.
Continuity mistake: Oliver, the brain tumour patient, is talking to Anna, Henry, and Carter. He has his right arm up on the bed railing - but as he says "cook", his arm is suddenly down in his lap.
Continuity mistake: When Doug is sitting at the cafeteria with Mark, Peter and baby Reese, his arm is stretched out on the table as Peter says, "fifteen minutes of quality time". The shot changes and suddenly there is no sign of his arm.
Continuity mistake: Mark is intubating the man who is paralyzed from the neck down. We can see his hands working - we know it is him by the splint on his wrist and he is talking as he works. However, Malik comes in and calls him away, and he rushes off, but the hands working on the patient don't change.
Of Past Regret and Future Fear - S4-E20
Continuity mistake: As Carter's grandmother is asking him if he'll be at his grandfather's dinner, we see him pick up a mug by its handle - but the next shot, from behind his shoulder, shows him holding the mug by the side.
Continuity mistake: Just before Peter bends over beside Reese, an extra is starting to walk behind them. The next shot shows the cereal on Peter's head and we should be able to still see the extra, but there's no sign of him.
Continuity mistake: At the beginning of the show, Doug is working on the computer while Mark is talking to him. At first there is a document sitting on top of a thick black book but that disappears after a couple of shots - and neither of them touched it.
Continuity mistake: During the last 2 minutes, Jerry is patronizing Dr. Waver. As he walks away, you see Dr. Greene (who has not been in this episode until now) walk across the hall in the background. A few moments later, outside, after Dr. Carter finishes chatting with the fire chief, he bumps into Dr. Greene outside. Dr. Greene is on his way in for his shift starting in 5 minutes and explains that he is coming straight from the airport. (00:43:22 - 00:44:50)
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.
