  • When Oliver explains about H.I.V.E., the organization that captured him, Ray compares it with S.P.E.C.T.R.E., a criminal and terrorist organization in the James Bond franchise.
  • This episode marks the last appearance of Sara on Arrow until "Invasion!". It is also her last appearance as The Canary, as she later adopts the identity White Canary.
  • So far, this is the only episode of Arrow that both Sara and Ray appear in before they joined the Legends. They wouldn't do so again until "Invasion!", which was after joining the Legends.
  • John Diggle comments, "Vodka is for wimps anyway. Tennessee whiskey - put some hair on your chest". However, he and Oliver start drinking a bottle with a black Johnny Walker label, which is a Scottish blended whisky, not Tennessee.
  • The pass code "4587" is used when Team Arrow break into Kord Industries to steal the quantum manifold. This is the same docket number of the case The People vs Moira Queen and Oliver's prison inmate serial number in Season 7.
  • Felicity refers to Diggle as "Spartan" to protect his identity. In the comics, Spartan is the leader of superhero team Wild C.A.T.S.. The character is known for his strength and durability, much like the character of John Diggle.
