EPISODE CONTEXT

As episode 1 of 26, 'Replacement' is purely foundational — it introduces the STN-J team, establishes Robin's role as the new operative, and defines the tonal DNA that will carry through the entire series. The early episodes that follow build on these character introductions with case-of-the-week structures while slowly deepening the mythology and interpersonal tensions seeded here. Robin and Amon's dynamic, barely sketched in this premiere, becomes one of the show's central threads as the narrative progresses toward its darker second half.
