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.
This is the first episode directed by co-showrunner, David Greenwalt. Fellow showrunner, Jim Kouf directed "Headache" in season 4.
521 Skyline Drive, the address of the barn where Hank was being held, is a reference to the episode number. While it is learned that Hank's address is 3045 Hudson Street, Mrs. Miller's house across the street has the address number 1950. Additionally, Hank's address was previously known to be the number 3055 in "Cold Blooded".
