Sir David notices a problem brewing when he sees the humanistic android, Shay, across the street pacing back and forth. Going against the orders of the schedule that it had precisely followed for thirty years, David feels the need to investigate, because he is one of the few remaining people who may be able to intervene. Having been taught two commands that were encoded as a fail-safe, should anything with Shay go wrong, Sir David was ordered to keep watch on the robot and interfere if anything was amiss. Shooing his daughter away, fearful that any interaction between them could get ugly, David sends her home and then walks to Shay. Using one of the commands, David is able to send Shay inside his home and restart his cycle, overriding whatever malfunction it seems to be having. David calls the Department, his old place of work, and warns them that they need to find the files on Shay where the other commands are stored. Because those files were analog, they seem to have been lost, so instead, they send an agent and two police officers. When they arrive, David pleads that they don't intervene with Shay without the proper commands and training, to no avail. The trio walks to Shay's house as David watches. When the door opens, Shay kills all three within seconds using methods ranging from decapitation to impalement. Calling his daughter in a panic, David tells her to flee the country, hoping that the water barrier will protect her. He hears Shay walk into his home, knowing only one way that he may be able to save all of Britain from an apocalypse: he tells it "Shay Corsham Worsted."
