Originally intended to air as Episode 9, but when the previous episode was pushed back due to sensitivities involving a terrorist attack in Paris, this episode was also rescheduled for the sake of continuity.
Originally titled "Deeks, M." but changed in order to save that title in case the producers decided to delve further back into the character's origin story.
This is the third time there has been a character named "Monica Lee". In Season 11 (The Debt) and this episode, the "Monica Lee" is a lawyer whose education was paid for by a drug dealer. In Season 14 (The Grey Man) "Monica Lee" is a former prostitute, with a daughter, who is being held hostage by a drug cartel.
Nick Chinlund who played LAPD Detective Bruce Steadman played a different character within the NCIS Universe. He played Detective Steve Rosetti on Recoil (2008).
