Not Arabella! It's Isabella, you moron. Look at Arabella's eyes. It's called genetics.

YEAH THATS WHAT I WAS THINKING!! ARABELLAS EYES WERE GREEN THEREFORE HER DAD MUST HAVE BEEN THE POPE-Y GUY (or another green eyed guy but idk) AND SHITABELLA HAS PINK EYES AND THE BLONDE HAIR SO THERES NO PROOF THAT SHES THE POPE-Y GUYS DAUGHTER! ITS SEEMS MORE IN LINE WITH THE PLOT TOO. "THE PRIDE OF THE DE MARE FAMILY IS ACTUALLY NOT A DE MARE" OR "PRIDED DAUGHTER OF THE DE MARES ILLEGITIMATE" IDK BUT LIKE THAT sorry for all the caps i just felt like it needed it lol
