The Better Call Saul episode centered on Mike Ehrmantraut’s police past is titled “Five-O.”
“Five-O” is the sixth episode of the first season. It largely shifts attention away from Jimmy McGill and follows Mike as he confronts the aftermath of events involving his son, Matt Ehrmantraut, a Philadelphia police officer. The episode explains why Mike left Philadelphia and how grief and guilt shaped his later choices.
The title uses “five-o,” a slang expression associated with the police. That title fits the episode’s focus on police work, corruption, and the consequences of Matt’s death. Jonathan Banks received major critical praise for the performance, which helped establish Mike as a fully developed central character rather than merely a supporting figure from Breaking Bad.
It is sometimes confused with “Pimento,” another first-season episode featuring Mike, but “Five-O” is the dedicated flashback story about his Philadelphia history.
