Casey is head of the student exchange program, and a kid from Central Tech will spend time with the Edisons. After he arrives and meets the family, Idella notices a piece of her jewellery is missing. She assumes John stole it, but doesn't have any proof. Casey thinks Idella is jumping to conclusions, but then Idella tells her she saw him put Ike's walkman into his bookbag. Casey confronts John, and he runs away angry. Later, Ike tells her that John bought his tape player, and was just putting it away. Ike eventually finds John, and everyone apologizes for their misconceptions.
