Trivia

• The title refers to Supergirl and the rest of the team finding out that Samantha and Reign are the same person.
• When Brainy attempts to figure out who scratched Winn, Winn begins describing Freddy Krueger, the main antagonist of the Nightmare on Elm Street franchise, which Kara and Alex quickly catch on to.
• When J'onn tells Kara that she simply has to try, she tells him that that isn't what Yoda, a character from the Star Wars franchise, would say. J'onn subsequently quotes Yoda, "do or do not", from the 1980 film The Empire Strikes Back.
• In this episode, it is shown that Reign's outfit supposedly materializes out of nowhere, contrary to previous episodes where Samantha was shown to have worn it underneath her clothes.
• When she's united with Purity and Pestilence, Reign says, "El mayarah". The phrase has previously been mentioned to be Kryptonese for "stronger together", and is what the House of El coat of arms - the "S" Kara wears on her suit - means.
• Grace Parker's "God Complex" comment was a possible nod to the 1993 thriller film, Malice in which a doctor gave a similar speech. It also starred Brenda Strong who portrays Lillian Luthor.
