One possibility is that the daughter could inherit her father's strength and leadership skills. She might grow up in Wakanda, learning the ways of the kingdom from her mother Nakia and the other elders. She could also have a special connection to the Panther Goddess, just like T'Challa did.
She could bring new ideas to Wakanda. With her unique perspective, being the child of two very different but important people, she might introduce reforms in areas like education or healthcare.
One idea could be a story where Nakia discovers a hidden threat to Wakanda while on a solo mission abroad and she has to secretly communicate with Black Panther (T'Challa) to stop it. They face challenges in coordinating without alerting the enemy and their relationship deepens through the shared danger.
