I am writing a scene where Princess Anyu, having just discovered who murdered Prince Consort Kian, is in one last, desperate conversation with her older sister. Anyu would be about 13 years old if she were an Earthling, not a Beinarian, and her older sister Leonora is about Earth age 17.
Their mother has just ordered Anyu to leave the palace (as she is the narrator of the first three books of the series, readers have known since book one she would have to leave home). Anyu doesn't want to leave her sister Leonora, especially given there is a very good chance the man who murdered their father will also kill her.
Is it cowardly for Anyu to beg and plead for her sister's life? Or is it what you would expect her to do?
No, it's not cowardly at all. Considering she's already in trouble, it's brave that she's putting her sister's welfare above her own.
