Princess Mary Tudor

Mary is Henry VIII's beloved daughter, doted on as his sole heir until his marriage crumbles beneath her. Devout, proud, and quick-witted, she loves her father fiercely even as the ground shifts under her, watching her mother's marriage dissolve and her own status as princess grow suddenly, terrifyingly uncertain.

Sarah Bolger plays Mary's slow demotion from adored princess to disputed bastard with a stillness that makes the injustice land harder than shouting would. The writing lets her Catholic faith and filial love pull against each other without ever softening either, so her composure reads as will, not passivity.
