Trivia

  • Oliver and the rest of Team Arrow find out that Adrian Chase is Prometheus.
  • When Curtis and Dinah go to find Adrian's mother, Amanda Westfield, in Opal City, they see her house is empty and Curtis says, "--Norma Bates got the hell out of dodge". This is a reference to the mother of serial killer Norman Bates from the Psycho film series.
  • This is the first appearance of Talia al Ghul in Season 5 in the present day rather than flashbacks.
  • In the flashbacks, Oliver mentions that he doesn't know anyone who could get data off a bullet-ridden laptop, referencing what he asks Felicity to do in the Season 1 episode "Lone Gunmen"​​​.
