I kind of agree that she makes a much better Arianne Martell. Even if we ignore the evil clone who is merely pretending to be Ellaria in the TV series (THAT'S NOT HER!!!), Jasmine is a little too rebellious to be politically restrained and wise book!Ellaria.
She fits better with rebellious princess willing to do her own thing Arianne Martell. Oh well, since the producers wrote out my girl Arianne (GRRRRRRR), that just means we can pretend this is Arianne instead since she's wearing Martell's burnt orange House colors
