To me, in fiction, the journey is mais important than the destination, so I’m ready to accept a world where the show reaches the same destination of the books por a different path. Having multiple angles on the same story will make both richer.
''I have decided to do that, yes. It’s something that involves a couple characters one whom is dead in the show but not dead in the books. So the show can’t do this, unfortunately.”
Although that was certainly the plan of George R.R. Martin and his publisher (not to mention our hope), we won’t read Book 6 ahead of Season 6 of Game of Thrones.
