In the Studio One version, the story ends at the Fords' apartment, with the audience invited to assume that Horace has been permanently transported back to his miserable past. In the Twilight Zone version, the story continues on: Laura leaves the apartment to find Horace, who magically transforms back into an adult and vows not to live in the past any longer.
