In a scene midway through the episode, where Allison is in her car, stopped in traffic while she's talking on the phone, you can see through the rear-view window that the driver of the convertible behind her is carrying on a conversation with someone just outside his car. He turns his head several times to look ahead, then back to speak to someone, and he also shrugs his shoulders after one of these times. If they were really in traffic the other person would have to be standing in the street.
