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 does a final walk through the West Wing thanking all his staff. At one point he stops and talks with Nancy and, asking about her mother, says, "I hope to see her real soon." Nancy is played by Renée Estevez, Martin Sheen's daughter; Renée Estevez's mother is Martin Sheen's wife, Janet, to whom Sheen has been married since 1961.
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.
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."
When President Barlett wrote the note to incoming President Santos, he folded the flap of the envelope inside and later, when President Santos opens the envelope, the flap was on the outside, as if someone else had opened the letter.
