I agree, and I honestly think that's the reason why she hates tia and shannet (other than them being in the way of. her plans). Because unlike her they got the privilege to be recognized as the head of the house. Unlike her who had to be sold to that son of a bitch of an emperor, and watched her incompetent brother get the seat of the head just because he was born a son, even though she was definitely more qualified.
I think Lavini has had a grudge with having a brother or the system at the time where sons are prized and daughters are seen as property, what with her saying he became head simply by being born a son. Looking back her brother had shown being human more, with previous chapters I've read of him showing hesitation and questioning the decisions of his sister. It's just a shame that Lavini is a rotten bitch to the core..also I love saying her name, so pretty~
