EPISODE CONTEXT

Coming off the momentum shift in Episode 3 ('Pursuit'), where the investigation veered into unexpected territory, 'Regret' functions as the first major deepening of the season's core narrative at the near-third mark of this 13-episode run. It bridges the early case-building episodes with what appears to be a more character-focused back half, surfacing critical information about key players. The groundwork laid here feeds directly into Episode 5 ('Persona'), suggesting the season is transitioning from establishing its world into confronting the consequences hidden within it.
