In the first episode the rest of the villagers freeze when instructed as Rover appears and attacks an unidentified man who does not comply. The same scenario reappears at the start of "Checkmate", the ninth episode, except that this time the man who does not comply is not attacked by Rover, prompting Number 6 to follow him and discover the human chess game, a key event in the episode.
