Continuity mistake: Within the space of what would appear to be more than 5 minutes in the ER, considering the continuous flow of action (starting with Kerry offering to get Pablo a taxi and ending with Dr. West examining the patient Lenny) the clock goes from 10:30 to 6:20. Shortly after that Dr. West pronounces Lenny dead, saying 13:38 (or 1:38).
