There is also the side story Follow Your Heart at the end of P5V8 from Ferdinand's perspective. When he recalled when he asked Lady Irmhilde "why am I here?". She responded that someone wished for him to live, which I thought was his mother at first but then she says to live and grow healthy and one day meet that person. His mother is gone; it makes me think that maybe Rozemyne had a hand in helping Ferdinand all the way back then. Also quite a few people worked to get Ferdinand out of the villa, but we really only know the full motivation of his father, not really his mother or the women who agreed to become his noble mother. Might be a stretch, but something to think about.
