No Good Deed Goes Unpunished - S9-E13
Character mistake: Dr. Corday finishes assessing a gun shot victim, then goes to the next trauma room to assess another. The steady cam follows her. She makes sure not to contaminate her gloves on the door, opening it with her elbows, but then goes straight to touching the next victim. Of course, in real life, she'd change gloves first. The shot never changes, so there's no chance of her changing gloves off camera. (00:12:30)
