This episode opens with the quote, "It is better to die on your feet than to live on your knees" which is attributed to Emiliano Zapata.
Continuing the Easter egg references hidden in the episodes, the registration address for the truck that was parked in front of Monroe's house is "521 Skyline Drive" for season 5, episode 21.
Had this episode remained its own individual weekly episode, it would have ended with a title card that read, "You guessed it... to be continued," after Nick sees the Black Claw mark on the wall across from his holding cell.
In the press release by NBC, the title was "Beginning of the End, Part One," despite this episode and "The Beginning of the End" not being written as a two part finale.
May 20, 2016 marked the second time where two new episodes aired on the same day ("The Beginning of the End" & this one). It was the first time since December 13, 2013 when "Cold Blooded" and "Twelve Days of Krampus" aired back to back.
