Continuity mistake: Casey and Kelly are on the roof smoking cigars when a man runs up carrying his daughter yelling for help. Both Casey and Kelly put down their cigars and are next seen sliding down a ladder with black gloves on. They were not smoking cigars wearing gloves, and wouldn't have time to put them on to get off the roof as fast as they did.
