With a man from the phone company coming, Moira MacTaggert rushes back to the mansion to answer the door. The man who answers the door is really Warhawk, who takes Moira down with a tranquilizer dart. He makes a run for the Danger Room computer controls and begins rigging something in the circuits when he is telepathically reminded by his mysterious employer that he will only retain his sanity if he succeeds in his mission.
