Styles Miller

Styles Miller is one of the identical Castor soldiers first glimpsed under military control, a genetic twin to men we already know but raised inside discipline rather than freedom. He follows orders, watches everything, and carries himself with the coiled stillness of someone trained to be a weapon rather than a person.

Ari Millen plays several nearly identical clones across the show, and the small differences he finds — a tilt of the head, a flicker of doubt behind the obedience — are what make Miller register as distinct rather than interchangeable. The performance turns genetic sameness into a puzzle worth watching closely.
