I think Ibelin is prob going to lose her marbles because Arwin is not falling for her. In the chapter where Latte is framed and Arwin transports Latte, Ibelin doesn’t defend her and looks worried at Latte and Arwin’s interactions. Ibelin just makes one of those backhanded comments, like when Latte was accused of stalking the Duke, that implies Latte is capable of doing what she’s accused of and highlights Ibelin’s “understanding” character. Even Duke genuinely stands up for her. Ibelin also never asks Latte about herself or stands up for her when the other socialites pick on her because she’s so self-involved. Ibelin not gonna turn out to be a good guy, prob less psycho than Lady P but for sure she’s gonna short circuit and do something shady to Latte.
