it's been a hot minute but I believe he brought back yvonne because he hoped that by restoring the position of the "lost daughter", the duccal family would cast penelope aside and she'd have nowhere to go or anyone to rely on. In his mind, that's the only way she'd become his
I don't remember that well either but I think he wanted to escape with Penelope and his people by bringing yvone to the house, Penelope got mad, he wanted to prove he was good enough to be his knight so I think he ratted out all of his people when trying to escape, and he went completely insane as well
i think part of it was also bc Yvonne brainwashed/manipulated him into thinking that was the only way he could make Penelope his
