As the Bartlets prepare to return to "normal" life, Abby asks President Bartlet "When's the last time you drove a car?" to which he replies "It's just like riding a bike, except with more horsepower, right?" The very first episode of "The West Wing" opened with the staff having to react to news of President Bartlet falling off a bicycle.
President Josiah "Jed" Bartlet did a final walk through the West Wing thanking all his staff. At one point he stop and talked with Nancy and asking about her mother, and says, "I hope to see her real soon." Nancy is played by Renée Estevez, Martin Sheen's daughter.
Allison Smith guest-stars in this episode in her recurring role as Mallory McGarry O'Brien. Smith started in show business at age ten by playing the title role in the Broadway Musical "Annie," in which she performed the song "Tomorrow"; this episode is also called "Tomorrow."
Both the season premiere and series finale end with the President asking "What's next?" The only difference is who is being asked. President Bartlet to Mrs. Landingham in the premiere and President Santos to Josh Lyman in the finale.
