In some ways, Paulina is luckier than all the other women in Acrea, being acknowledged by the King himself, being bestowed land even though she's a woman, having a high position even though she's a woman, no expectations of having children even though she's a woman. Paulina is quite dense in some areas, especially in areas she has never experienced before. It's good character development for her to talk to the concubines and understand and sympathise with them
