Yeah you could be right -- I haven't read the books (yet), so I certainly can't fully explain Bran's powers, but this video makes some compelling arguments, if even not 100% correct in all facets; and the YouTuber did make some accurate predictions about Jon killing Dany and Bran sitting on the Iron throne after being 'democratically' elected (though actually it's an oligarchy not a democracy).Im not sure thats entirely true as bran can see both past and future??? just that the future depends on the paths people take which could lead to different outcomes so he cant be entirely sure how its shaped till that moment happens...
Also, being the three eyed raven im not sure hes supposed to influence any outcomes as much as be a keeper of stories and be able to predict certain outcomes...
Then again, i’ve not read the books so not sure if there was any side stories hinting bran had more influence than was shown on TV???
