@maanasarovar maybe bhanumati learning and settling into hastinapur as not only a wife, but also as a valuable and learned member of the family, perhaps her expressing her own opinions on a courtly matter, which could also lead upto duryodhan valuing her insight and seeing more to her. also i think there was a part in the last chapter where he asks her to tell him something about herself, maybe she tells him something about her childhood. these are just some ideas, i'm sure whatever you come up with will be an enjoyable read :)
