Development directed the episode. The series was announced in March 2021, with
Rian Johnson serving as creator, writer, director and executive producer. Johnson stated that the series would delve into "the type of fun, character driven, case-of-the-week mystery goodness I grew up watching." The episode was written by co-executive producer Laura Deeley, and directed by main lead actress
Natasha Lyonne. This was Deeley's second writing credit, and Lyonne's third directing credit for the show. Before the episode aired, Johnson said that the episode would be part of a two-parter season finale, "It's something that — in a really fun, unexpected way — caps the season. It's not just another
Poker Face episode. It’s a finale-finale for the season. [...] It's almost like the last two are a two-parter. Ti West directed episode 11 and Natasha directed 12 [the finale], and you have two beautiful, beautiful brains concocting this one-two punch that is so surprising. We didn't even show it to the press."
Writing The episode reveals that Alex was a deadly assassin, setting her as Charlie's nemesis. Co-executive producer Laura Deeley came up with the plot twist, introducing her as someone who can challenge Charlie's lie detector. Showrunner
Tony Tost explained, "We've got our kind of spin on a classic old-school detective, and there's a set number of archetypes there. So we thought it would be fun to introduce a character that seems like she's going to be Charlie's
Watson, but ends up being her
Moriarty." The writers decided that Alex would come out to kill Beatrix Hasp, as Tost says "what would justify the world's greatest hit woman to come in?"
Patti Harrison added, "The actual process of building the character and stuff, was really fun. It was really daunting. I appreciated how much space I had with fleshing out the character, but I do think they also wanted something specifically with the tone, and I think a lot of times, that's challenging if you’re in a dramedy or a show that tonally needs to be able to get back to the emotional stakes without being too hammy or weird."
Simon Helberg commented on Luca's decision to give a head start to Charlie before she is pursued by the FBI, "It was really spectacular. It feels like they've really teed up, in terms of the characters, that they're in this impossible situation. They're both sort of attracted and repelled by one another, given who they are and what they need and want. And you feel that in that moment, and you wonder, 'Oh my God, how are they ever going to cross paths again?' But of course, how are they not? We want to see that and yet it feels kind of tragic."
Casting The announcement of the series included that
Natasha Lyonne would serve as the main lead actress. As Johnson explained, the role was "completely cut to measure for her." Due to the series' procedural aspects, the episodes feature several guest stars. Johnson was inspired by the amount of actors who guest starred on
Columbo, wanting to deem each guest star as the star of the episode, which allowed them to attract many actors. ==Critical reception==
