For the eponymous location, see Lian Yu (island).
"I knew it would come to this. Your son is dead, Oliver."
"I don't believe you because you're a liar. You're lying to me to manipulate me into doing what you want, but, Adrian, here's the thing. If you are telling the truth... if you killed my son, I am never going to be the person you want me to be. Not ever.
Adrian Chase and Oliver Queen

  • This is the final episode of Arrow to feature flashbacks regarding the 5 years Oliver was away from Starling City (later known as Star City). However, this is not the final episode of the series.
  • The flashback when Oliver runs to alert passing fishermen, as well as being rescued by them, was first shown in "Pilot". This marks the only time a clip has appeared in both the flashback storyline and the present storyline.
  • The first line of the episode was "The name of the island they found me on is Lian Yu. It's Mandarin, for Purgatory", spoken by Oliver. This is the very first line that was ever said on the show, in "Pilot".
  • This is the second episode to take place entirely on Lian Yu (though Starling City briefly appears in the final flashback). The first is "The Return".
  • This episode marks the first and last appearance of Digger Harkness since "The Brave and the Bold".
  • Stephen Amell revealed on May 21 that another yet unannounced surprise cameo appearance would happen during this episode,[3] which was revealed to be Susanna Thompson as Moira Queen.
  • The first fight between Oliver and Adrian Chase, along with the flashback of Oliver and Konstantin Kovar, slightly mirrors the season 2 finale, "Unthinkable", in which Oliver and Slade Wilson were fighting in the present and in the flashback. It also happened after that when Oliver ran through the forest past and present.
  • Adrian's death is very similar to Robert Queen's. Both put a gun to their heads and shoot themselves through the right temple, in front of Oliver, on a boat, within sight of Lian Yu.
    • Adrian's death also mirrors his comic counterpart's suicide.
  • Three out of the five major Arrow season antagonists appear: Malcolm Merlyn, Slade Wilson and Adrian Chase. However, only the latter appears in an antagonistic role; Malcolm and Slade are both seen acting as supporting protagonists.
  • After Curtis finds Adrian's plane, he yells, "De plane boss, de plane!", impersonating the character Tattoo from the show Fantasy Island.
  • The title card for this episode matches the title card for season 1. Even the music is the same.
