"Among the many misconceptions humanity holds dear is the fallacy that all beings are created equal. In truth, there are those who are greater. They are called heroes. But even among heroes, there are different echelons. The highest belong to those known as the paragons. And they are the only hope of all creation."

Trivia

 * This is the first episode of the series not to feature in 6 years, since the season 1 episode "Betrayal".
 * This episode feature many references to past episodes of the show, mainly from Season 1:
 * At the start of the episode, Oliver experiences events in extremely similar ways he experienced the same events on Earth-1 in, but with a few changes, notably Malcolm Merlyn taking Walter's role as well as Tommy Merlyn taking Thea's role.
 * The scene where Oliver is rescued from the island is mostly made of archive footage from with some changes notably such as Oliver's hair and beard and instead of having a Deathstroke mask, the island has a Batman cowl.
 * Oliver tries to escape Diggle's car but Diggle beats him to the chase, revealing he is the Earth-1 version. He tells Oliver that he fooled him once which refers to when Oliver first tried it and got away with it in.
 * After Oliver leaves a party at Verdant, Diggle points out he's going the wrong way. The same thing happened in . Also, Oliver ends up stopping Diggle the same way he stopped him in that episode, even pointing out that he always falls for that move.
 * Oliver and Tommy mention that Thea used to say "The dead don't want anything. It's one of the benefits of being dead." Earth-1 Thea said the same thing in, and Oliver referenced that quote to her in.
 * Oliver thinks he found Felicity and mentions "the pen should be red" in reference to when he met her during where she was using a red pen.
 * Moira mentioned that Thea died from a Vertigo overdose on her 18th birthday. This is a reference to, where Thea drove after taking Vertigo on her 18th birthday which resulted in her going to court.
 * The fight scene in the hallway has some resemblances to the one Oliver had in.
 * The first fight between Oliver (as the Green Arrow) and Tommy (as the Dark Archer) is similar to the fight between Oliver and Malcolm in . When Oliver finds out Tommy is the Dark Archer, he reacts similarly to how Malcolm did in that episode when he found out Oliver was the Hood, except Tommy wakes up and promptly escapes.
 * Malcolm discusses the fight between the Hood and the Dark Archer to Dinah in a similar way Oliver told Quentin about the Hood saving him in.
 * Oliver gets chained up by Tommy the same way he got chained by Malcolm in . He later gets out of the situation the same way he did in that episode,  while Diggle saves him and jokes that he found him from a tracker in his shoe the way he originally did in that episode
 * The final fight between Oliver and Tommy on a roof with the climax of the Undertaking at hand is exteremly similar to the final fight between Oliver and Malcolm in.
 * Oliver says to Adrian that he's 10 steps ahead of him, the same thing Earth-1 Adrian used to tell Oliver in Season 5.
 * The city where Oliver and company reside has not been called Starling City since the fourth season premiere, when it was renamed Star City as a method of rebranding after the repeated tragedies and in honor of Ray Palmer who was believed dead. However, its Earth-2 counterpart never underwent the change, albeit the timeline being pushed backwards to which the present-day events mirror that of season 1, when it was in fact called "Starling City".
 * Bruce Wayne's quote shared by Adrian Chase, "once you eliminate the impossible, whatever remains, no matter how improbable, must be the truth", is taken from Sherlock Holmes.
 * This is the only episode to credit Katie Cassidy Rodgers in the special appearance bill despite being a series regular . In addition, she was also billed as simply Katie Cassidy..
 * Beth Schwartz sought permission from writers to destroy Earth-2.
