4. Sansa Stark
If a Disney princess had night terrors, the story of Sansa Stark might be what woke her up screaming. Often overlooked in favor of her killer kid sister, the elder Stark sibling has had all her illusions about the world, and her safety in it, shattered. But her quiet, innate political shrewdness and emotional strength have enabled her to survive in a royal court that likely would have cost every other member of her family their heads. She's the show's best-kept secret.
