When Detective Christina Vega meets Bosch, she tells him that one of the reasons she wants to work with him is that she heard he threw Lt. Pounds through a window. This scene was inspired by a detective that writer Elle Johnson met at the CHIA (California Homicide Investigators Association) convention in Vegas, who told her she loved that Bosch can do and say the things she wishes she could but can't.
Writer-producer Elle Johnson's father was a Manhattan parole officer, and her uncle was a homicide detective in the Bronx. Elle landed her first TV writing job on the strength of a script she wrote about her uncle's investigation into the murder of his daughter, Elle's cousin Karen.
Writer Elle Johnson wanted to honor what families go through in cases like the Danielle Skyler murder and also how it affects law enforcement, who see the toll on the family and work to bring them justice. A case coming back in this way is a cop's worse nightmare.
When Jerry is doing a follow-up investigation at the airport, the aircraft closest to the fence is a Fouga CM.170 Magister, a since-retired jet trainer aircraft used primarily by the French Air Force. The aircraft is easily identified by its distinctive V-shaped tail.
This season Maddie is maturing, and Bosch begins to treat her more as an adult, discussing the Preston Borders case with her and inviting her into his process. This gave actors Madison Lintz and Titus Welliver new layers to play, as their characters begin to relate almost as peers, not just father-daughter.
