This episode was likely based on The Hangover because it shares many similarities: The group was 'drugged' which resulted in them getting out of control and having no memories of the night before. They also piece together what happened the night before via clues and video footages. The group steals a lemur, which results in them getting in trouble with the Amos Fortune, similar to how the cast of The Hangover got in trouble with Mike Tyson. The group has an unplanned wedding the night before.
This is the last episode of the series to feature all of the main cast members in the same room together.
Batman and Wonder Woman are alluded to for the first time by Chloe, as two of the heroes she may have possibly met when she was away with the Suicide Squad.
Justin Hartley makes his 50th appearance as Oliver Queen in this episode. He joins Tom Welling, Kristin Kreuk, Michael Rosenbaum, Annette O'Toole, John Schneider, Allison Mack, Sam Jones III, John Glover and Erica Durance as the 10 actors to appear in 50 or more episodes of the series.
Chloe returning to journalism was hinted at previously in the closing scene of "Masquerade" in which she mentioned not feeling like herself since she was in her senior year of high school and working at the Torch.
