Dominique DiPierro

Dominique "Dom" DiPierro is an FBI agent chasing the fsociety hack with a bloodhound's patience and a lonely, insomniac focus that leaves little room for a life outside the case. Sharp, disciplined, and quietly isolated, she senses the conspiracy runs deeper than her bosses want to admit, and keeps pulling threads anyway.

Gummer plays Dom's competence and her loneliness as the same texture rather than opposites, so scenes of surveillance work double as portraits of a woman who's forgotten how to be anywhere else. As the sole investigator taking the hack seriously, she becomes the show's clearest mirror for paranoia earned through actual diligence.
