  • This episode shares the same name of Arrow's "Left Behind". This name can be explained by the presence of Arrow Season 3's main antagonist, Ra's al Ghul, or by the fact that Sara Lance, Kendra Saunders, and Ray Palmer were left behind by the Waverider.
  • One of Ray's students is William Gates Sr., the father of Microsoft co-founder Bill Gates.

  • The med bay of the Waverider can recreate missing limbs; Snart froze and smashed his hand to get free of some handcuffs, and Gideon later recreates his hand for him.
  • This episode marks the first appearance of Ra's al Ghul's daughter, Talia, who would go on to have a major role in Season 5 of Arrow. Talia al Ghul is famously known in the comics as the youngest daughter of Ra's al Ghul, as well as the lover of Batman and mother of their son, Damian Wayne
  • The Shadow Record mentions a member of the League called Fadir Nasser, who in the comics is known as the White Ghost.
    • In the comics, the White Ghost's real name is Dusan al Ghul, the only son of Ra's al Ghul.
  • The Shadow Record also mentions four other villains from the comics:
    • Malaq, a member of the League who had a single appearance in Detective Comics Vol. 1, issue #750 from November 2000.
    • Tigris, a female member of the League who is a minor villainess and ally to Batgirl (Cassandra Cain).

  • When Ray questioned why Rip didn't attempt to go back to when the Waverider was hijacked, so to spare him, Sara, and Kendra two years in the past, Rip only offers a cop-out excuse.
  • Sara and Kendra are seen playing the modern Game of Life in 1958. While the original Game of Life was released in 1860, the board they are using was not introduced until 1960 and is noted as the 100th anniversary edition.
  • One of Ray's physics students in 1960 is revealed to be the father of Bill Gates, William Gates Sr. In real life however, Bill Gates Sr. graduated from the University of Washington in 1950 and was a law student, not a physicist.

However, in this episode, it was shown that Ra's was challenged in 1960.
    • It is possible that Ra's doesn't count 1960 because he wasn't the one who fought Rip's champion.
  • Sara tells Ra's to send his future daughter, Nyssa, on Lian Yu in October 2008. However, since the Arrow Season 2 flashbacks take place in 2008-2009, Nyssa would have found Sara in 2009, not 2008.
    • Whether a happy accident or a conscious decision by the writers, Sara's statement is actually correct. The Season 2 flashbacks begin in September 2008, but if you keep track of the timeline from the beginning to the end of the season 2 flashbacks, you will see that they take place in only 10 days, meaning Sara would have been stranded on Lian Yu in October 2008.
