Episode 505 is titled "Tunnel Vision." According to the show's technical advisors, the negative side of tunnel vision is when a cop gets fixated on the idea of a suspect's guilt and views all evidence through that lens, excluding anything that runs contrary to that theory. This is what Christina Henry (Bianca Kajlich) does in terms of Bosch, making assumptions that he's guilty. The personal ax she has to grind in effect makes her guilty of doing what she accuses the cops of doing years ago. Her tunnel vision is more emotional.
The balcony scene at home is a reversal of the usual, with Bosch coming out to the railing to Maddie, rather than the other way around. She's looking for guidance, because she's wrapped up in a case and hoping for justice.
For his first time directing an episode of the show, frequent "Bosch" cinematographer Patrick Cady was tasked with capturing the electric tension of the scene in which Bosch (Titus Welliver) visits Preston Borders (Chris Browning) in prison for the first time since he put him away.
Maddie is still carrying the grief of losing her mother in season 4, and she feels the case wasn't handled well. Now she's involved in the sexual assault case and wants to make sure it's done right. This mirrors her dad's efforts to handle both the Borders and pharmacy cases.
The "Bosch" writers always look for way to create scenes in which emotions can be conveyed without dialogue. An example from season 5 grew out of the scene of Dwight Wise, Gary's father, telling J. Edgar to keep his kids close, because you never know what can happen. Later, we can imagine J. Edgar thinking back on this as he silently watches his kids play.
