Rachel Duncan

Rachel Duncan runs a tight ship at the Dyad Institute, immaculate in tailored suits and clipped precision. Unlike the other women she resembles, she has always known exactly what she is, and she treats that knowledge as an advantage rather than a wound. Controlled, calculating, and utterly unsentimental, she wants order — and she expects to be the one enforcing it.

Tatiana Maslany plays Rachel as glacial where her other selves are chaotic, and the contrast is the point: same face, entirely different animal. Every clipped line suggests decades of practiced composure barely containing something colder underneath. Watching Maslany hold Rachel so still, while still making her riveting, is a masterclass in what restraint can do on screen.
