Delphine Cormier

Delphine arrives as Cosima's new lab partner at grad school, all quiet confidence and unreadable warmth. She's smart, French, and disarmingly direct about wanting Cosima, even as questions swirl around who she really works for. She watches more than she reveals, straddling affection and allegiance from the very first conversation.

Brochu plays Delphine as someone perpetually caught between sincerity and strategy, and the show never lets us settle on which is winning. Her romance with Cosima gives the show's clone conspiracy an emotional stake outside the sisterhood itself, and Brochu's stillness makes every small tell of conflicted loyalty land hard.
