I like how "his" rewriting is basically a collection of popular fan theories that have been around on reddit and whatnot for years
Jon should have been the one to kill the NK, while dying in the process. It was his mission for like, 2 seasons. Arya had fuck all to do with any of it, she basically pops up out of nowhere and killsteals.
That would also make Dany's snapping a lot more logical, since it'd be the second time she loses the man she loves - and this time arguably Cersei is responsible, since she told them she'd send help to fight the dead (which was Jon's preoccupation for a while). They never presented it as her giving that much of a fuck about Jorah.
Obviously, that would have required first a little bit more development to Jon and Dany's relationship than what was basically a couple of tinder dates. The whole tension about who gets the throne was just distinguished mentally-challenged as well.
