Arya Stark

The youngest daughter of Winterfell isn't interested in needlepoint or ladylike manners — she'd rather practice archery, roam the castle, and needle her siblings. Fierce, curious, and stubbornly herself, Arya bristles against every expectation placed on a highborn girl, preferring dirt under her nails to a proper dress.

Maisie Williams plays her with a scrappy, unforced honesty that never tips into precociousness — you believe this is exactly how a defiant ten-year-old would act if the world around her were falling apart. The writing trusts her interiority long before it explains where she's headed, and Williams makes every small act of rebellion feel like a whole personality.
