  • The title is a nod to the 1987 film Superman IV: The Quest for Peace which had Jon Cryer as Lex Luthor's nephew, Lenny Luthor.
  • In the penultimate scene, it's revealed that Eve has been working for an organization called Leviathan. In the comics, Leviathan is an offshoot of the League of Assassins led by Talia al Ghul; the League and Talia's father, Ra's al Ghul, appear in season three of Arrow, while Talia recurs in season five and appears once in season seven.
  • Debut of J'onn J'onzz' brother, Ma'alefa'ak.
