"Game of Thrones" has ended, alas. But Business Insider reports there are still plenty of details fans might not know. For instance, Arya Stark had a long kill list that gets shorter and shorter as she becomes a more skilled assassin. But Ser Ilyn Payne mysteriously disappeared, because the actor, Wilko Johnson, got cancer. Fortunately, he recovered! Also, a King's Landing scene looks a lot more orange and red, whereas a Castle Black scene is more blue-toned.
