Instead of 22 standalone cases, she rewrote the entire season arc in 72 hours. Episode 1–3: Leo’s first shootings and the revelation that his late wife’s death—ruled a carjacking—was actually a cover-up.

Episode 12–13: Leo arrests a fellow cop (his former hero) for evidence tampering. The season ends not with a promotion, but with Leo suspended, badge on the table, voiceover: “They said make it to 13. I didn’t say which 13.” Mira chose the latter
