• Several to Doctor Who (fitting as one of the principal actors is Peter Davison) including Uljyabaan's use of "the mind probe!" and a prediction that someone will meet a figure who will "knock four times."

Indeed, Richard, played by Davison, spends a good portion of "Taking Overs" in cricket uniform.
