(Ed note: currently, if that little clause was not in place, he would currently be 13th in line after Pauline Ducruet. Technically, he is on top of the "pool" of Grimaldi descendants eligible for the throne if the current line fails. Yes. I counted right-11th: Jacques, Gabriella, Caroline, Andrea, Pierre, Stefano, Francesco, Charlotte, Alexandra, Stephanie, Louis, Pauline....Sacha, Maximilian & India Santo Domingo ARE NOT GRIMALDIS, therefore cannot be in line for the throne, unlike Raphael, Jazmin, Alexandre, and Camille whom are all illegitimate so they are not eligible unless their parents marry in the future)
