It does, however, inform us of the return of both Nyssa – who hasn’t appeared since the third episode of this season – and Colton Haynes’ Roy, who left Star(ling) City back in season three after faking his own death to acquit Oliver. Also making his debut this episode is villain The Calculator, played by Tom Amandes.
