Character mistake: This has happened a few times before on this show. At the beginning of the episode, they are having a very loud party in the ER. There is no possible way this could ever happen in a real hospital. Even during an extremely quiet period, which rarely happens at County General, it would be extremely rude and unprofessional for patients. There's no way Kerry would be OK with such activities.
