Catwoman parks the Batmobile and runs up a flight of stairs. When Batman and Robin arrive in the patrol car moments later, the Batmobile is suddenly in a different location, parked much closer to the wall.
Batman is in the Batcave and places an antidote for Robin on the desk before he leaves with Catwoman. When he places the antidote on the desk, the background behind the desk is of various computers. The camera cuts to Batman walking to the Batmobile, where Batman then leaves with Catwoman. The camera then cuts back to the desk, but this time the background behind the desk is of the service elevator.
