  • The title references the 1984 film of the same name.
  • This episode marks the first appearances of Izabela Vidovic and Olivia Nikkanen as the younger versions of Kara and Alex since season three's flashback episode "Midvale".
  • When Supergirl is in Red Daughter's apartment, she stands in front of a mirror, potentially referencing Red Daughter's similarity to Bizarro.
  • There are two references to Star Wars made throughout the episode.
    • The "Wookiee gambit", that Dreamer mentions is an allusion to the scene in Star Wars: Episode IV - A New Hope (1977) when Luke and Han, disguised as stormtroopers, pretend to have captured Chewbacca in order to access the detention area in the Death Star where Princess Leia is being held prisoner.
    • Brainy mentions having been shamed for his unawareness of Star Wars: Episode IV - A New Hope, once before. He's referring to a scene in "Battles Lost and Won" when Kara quotes Han Solo to him; Brainy inquires whether she's making a film reference, and she expresses her surprise that they've never shown him Star Wars.
  • As they had done it with DC's Legends of Tomorrow, which was done in Japanese, the Supergirl logo was briefly done in Russian.
