What Is “Breaking Badly” About?

Stan helps Dr. Pentos sell illegal candy to students at the middle school. The arrangement puts Stan on the wrong side of the rules as Pentos brings his business to a young customer base.

Meanwhile, Flute mentors Otis during his first undercover operation. The two storylines put a candy-selling scheme and an inexperienced detective’s assignment at the center of tonight’s episode.

The official synopsis does not disclose whether the operation intersects with Pentos’ business or how either storyline ends. It leaves Stan’s involvement and Flute’s approach to mentoring for the episode to explore.
