Morwena Chynoweth

Morwena Chynoweth is a vicar's niece taken on as governess to the Poldark children, a shy, clever young woman kept small by an overbearing aunt who controls her every move. She reads, she watches, she says little. A tentative, unlikely warmth grows between her and Drake Carne, a connection that seems to promise her the first real choice of her own life.

Ellise Chappell plays her almost entirely through stillness — the darting eyes, the swallowed opinion, the flinch before she can stop it. The writing gives Morwena real intelligence and no outlet for it, and Chappell makes that suppression legible without ever tipping into melodrama, so her quiet becomes the most eloquent thing on screen.
