If Arya was a Lady, it would change her story quite drastically. As a Lady, she would be expected to follow traditional gender roles and marry into a powerful family to secure political alliances. She would also be expected to focus on learning practical skills such as sewing, dancing, and music, rather than swordplay and archery. However, given Arya's rebellious nature and her desire to break free from societal norms, it is possible that she would resist these expectations and continue to pursue her interest in combat and adventure. She might face more pushback and resistance from her family and society, but she could still find a way to achieve her goals and remain true to herself. Overall, while being a Lady would certainly change Arya's story, it might not drastically alter her character or resolve.
