◈Narrative Significance
Mariano is built entirely out of absence. For eight episodes he is a voice on a phone, a surname in the credits, and the reason the most controlled character in the show loses her composure — a structure that makes the audience assemble him from other people's fear before they ever see his face. When he finally appears in the finale, the reveal is not that he is dangerous but that he was the actual power the whole time: the Jacksons were the visible operation, not the owners of it.
