Character mistake: In the season 8 episode 'Never Say Never,' In the opening scene before the credits, Dr. Susan Lewis returns to the ER to meet with Mark Greene for lunch. She is standing at the admit. desk and asks Frank, then Luca where she can find Dr. Green. The shot then pans out to a view of her back, exposing the curtain areas. In that shot, Dr. Green walks right past her, no more than 10 feet away. Due to their angles, there is no possible way neither of them would have not seen each other at that moment, yet he walks past, and she continues her hunt for him. (02:15:20)
Character mistake: Carter tells the mother of the smallpox infected children that no one has seen smallpox for 50 years. The episode aired in 2002, WHO didn't start its global eradication of smallpox until late 1950's and the last case was reported in 1978, which is only about 20 years.
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.
