Felicity is frantic when she learns that Ray is alive and being held by Damien Darhk. Felicity's guilt over not finding Ray sooner causes tension between her and Oliver. Meanwhile, Sara joins Laurel, Thea and the team on a rescue mission for Ray. However, the effects of the Lazarus Pit take over and threaten to jeopardize the entire operation. Donna Smoak returns to Star City.[1]

  • When Oliver explains about 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.
