An old friend stops by the airport and lets Brian know that Carol has dumped the guy she dumped Brian for, and she's moving to London. Brian can't resist the urge to check on her itinerary, and notes that she's flying through Boston and has a four-hour layover there. He tries to get ahold of her, but is unable to, so he leaves a message to meet him at the top of the Prudential building. But his efforts to get to Boston are scuttled, first by Sandpiper's plane being out of commission, Roy's flight to Boston being booked up, and finally, a fog that virtually shuts down the airport. But Brian's passion for seeing Carol causes him to ignore the risk and take off in Joe's plane. He then waits at the Prudential building for Carol.
