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.

Visible crew/equipment: When Dr. DeRaad asks Kerry if she knows Paul Sobriki she tells him to check the board, and as Kerry walks past the door we can see the reflection of a crouched crew member walking backwards, pulling a rolling microphone stand. (00:02:45)

Visible crew/equipment: When Mark and Doug are talking about Jen, Doug says, "If you can't make a marriage work, how the hell am I gonna," and just as Mark joins Susan at the desk, the reflection of the moving boom pole/mic is visible on the glass behind Mark. (00:22:15)
Visible crew/equipment: At the very start, the camera tracks past the ambulance entrance towards admitting, and when the camera turns as Rolando asks, "What's your ETA?" the reflection of the camera operator is visible on the glass. (00:00:20)
Continuity mistake: When young Robbie stands at the doorway of the trauma room with his father's body, the green door to the back supply cabinet is wide open and the floor is relatively clean, but when Robbie stands beside his father there are changes such as that cabinet door is closed, and the floor is littered with used latex gloves, etc. Then the cabinet door is wide open again when Carol and Luka walk in.

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.
