eh what dranger said has been covered in the show by now. perhaps some details behind it are expanded in the books, but it's not a spoiler anymore

by the time the next season is over, there will be no spoilers left. only deeper insight from the books. like im pretty sure ive figured out where one of the main characters will end up, but it's not something you could come to just by watching the show even though the show is laying the groundwork for it
