This episode serves as a reason for Dana Plato's departure after this season. Off camera, Kimberly moves to Paris to study abroad (during the show's final two seasons).
Though the character of Kimberly is said to not be pregnant, actress Dana Plato was actually pregnant at the time. This episode aired in December 1983 and Dana's son, Tyler, was born 7 months later in July 1984. Her pregnancy is the reason why she leaves the show.
