Trivia: Blanca Gomez, the wife of DEA Agent Steve Gomez, appears for the first and only time in the courtroom scene during Jimmy McGill's final hearing. Although she had been mentioned many times in both Breaking Bad and Better Call Saul, she had never been seen until this moment. She is seated next to Marie Schrader but does not have any spoken lines.
Trivia: Robert Forster filmed his scene in this episode at the same time that he filmed his scene in El Camino. He is having a phone conversation with Bob Odenkirk, but Odenkirk shot his part later. Unfortunately, Forster passed months earlier (coincidentally on El Camino's release date) and sadly never got to see his work in neither this nor El Camino.
Trivia: Saul's rival attorney, later turned defense lawyer, Bill Oakley, has the same name as a writer for The Simpsons. Bob Odenkirk's brother, Bill, is also a writer for The Simpsons.
Trivia: The scene in which Saul tricks a witness on the stand into identifying a defendant that he had swapped out with a doppelganger may be based on a real-life incident from 1994, in which a lawyer swapped out his client with a lookalike, leading to the arresting officer for the case to misidentify the defendant. The judge presiding over the case then ordered a not guilty verdict and held the defense lawyer in contempt for deception. He ended up only having to pay a $400 fine as punishment.

Trivia: When Kim is sitting down to eat with Clifford Main, she mentions the place gives Java Joe's a run for its money. Java Joe's is actually the name of the real-life coffee shop whose building exterior was used as Tuco's headquarters in Breaking Bad.
Trivia: One of the diners seen is "El Camino Dinning Room" (for example in episode 1 and 4, it's where Kim is talking to her pro bono clients). "El Camino" was the name of the "Breaking Bad" movie.
Trivia: On July 27th, 2021 while filming the sixth and final season, Bob Odenkirk suffered a minor heart attack and collapsed on set.
Trivia: The guy who breaks the two brothers' legs is Tuco Salamanca, a drug dealer that makes a deal to sell the blue meth with Walter White in Breaking Bad.
Suggested correction: I'm not sure this qualifies as trivia. Throughout the entire series, there are several characters that had very prominent roles in Breaking Bad. Tuco is, without question, extremely recognizable the moment we see him on screen.
