These videos are all the same. take some minor tidbit that doesn't mean anything and could be interpreted one way or another, then reach for anything else that you can twist to make it support your theory.
Margaery, fine, but probably red herring. Dany? obvious, but yeah, probably won't get to westeros before Cersei's children and even herself becomes wormfood. So so far, decent explanation of the prophecy without making any stupid claims.
Then we come to Arianne, who is the most likely candidate, literally fulfilling all of the prophecy. And yet the video says she probably isn't, because she doesn't? WTF are you smoking?
Yeah Arianne will probably wed Aegon (we know this because she is a POV character, we know her, she is totally going to try and make an allegiance via marriage to Faegon, even if she is show evidence that he isn't Aegon. Arianne isn't in a position to kill Cersei's children? did she even read the fucking books? Literally that is HER GOAL. She already tried to crown myrcella, and she almost got her killed. All to cause a war between cersei's two children! She is literally the only character in a position to make that part of the prophecy come true.
Instead she then lists sansa stark? dafuq is she smoking? Then Jeyne Westerling? claiming that this is the biggest contention from the books? are you insane. grrm spelled it out in the most blunt method possible that she isn't pregnant. She is a character so minor, she was never even introduced! She was so forgettable he even forgot what she looked like! there is no contention here. Annnd then the rest of the video is nothing but tin foil hat stretching.
