Stiorra

Stiorra is the daughter of Uhtred, raised between two worlds and belonging fully to neither — pagan blood in a land pressing toward Christianity, a Dane's instincts inside a life her father tries to steer toward safety. She is watchful and unyielding, chafing at the marriage and quiet obedience expected of her, drawn instead toward the freedom and danger her father has always lived by.

The show has spent years building Uhtred's divided loyalties, and Stiorra becomes the place where that inheritance lands on someone with no power yet to act on it. Hartley plays her with a coiled patience, letting the character's stubbornness read as inevitability rather than teenage defiance — you believe she's her father's daughter before the plot even insists on it.
