Questor (who becomes more "human" as the story progresses) only knows that it has something to do with an "aquatic vehicle" — a boat — and that if he does not find Vaslovik before the end of a countdown, the nuclear generator in his abdomen will overload and explode. Vaslovik had programmed this into him to prevent his creation from being misused, and time is running out. The pair, traveling to England, escape from custody and travel to the home of Lady Helena Trimble (Dana Wynter), who had known and worked with Vaslovik. (Her name was an homage to Bjo Trimble, who had led the fan campaign to keep "Star Trek" on the air.) After Robinson refuses Questor's naïve suggestion that the scientist seduce Lady Helena as a way to get information, Questor announces that he will make the attempt, adding, "I am fully functional."
