Caution: Spoilers to the final of the season 5!
Stannis Barateon According to Natter, absolutely, it is 100%, guaranteed dead - and in the season 6 will not return. "Everyone understands that Stannis is not left for what to live. This is the situation in which Stannis was ready to die. "
SANSA STARK AND THEON GRAYDY - In the same way, absolutely 100% and guaranteed - alive. Director David Natter promises a kind of happy hepping end for what happened to the heroes in the final of the 5th season - "You can confidently assume that that jump they survived." However, those who read Martin's books already know about this - although Sansa in the book was not, the theon on the plot survived a similar fall.
Mircella Barateon In the 6th season "Games of the Thrones" will not. David Benioff and Dan Wayss, the scenarios of the series, confirmed her death - and at the same time hinted at the coming confrontation of Serne and Tyrion: "She believes that it was Tyrion who took Mircell from her. She still blame him for the death of Joffrey, and it is he who is that Mircell was in Dorn. So, in her reality, the death of both her children is his fault. So she has enough causes for deadly hatred. "
By the way, Lena Hidi, who plays the role of Sernei in the "Game of Thrones", after the premiere of the 5 season final, also promised the serial fans a pretty portion of hatred and madness. According to her, the events of the 5th season changed her heroine - and made it even more insane. "Yes, they changed it. From here it begins her way to true madness, "she said. "She did not refuse the dream of power and revenge. Sersa will not forgive and will not forget, so, I think, a lot of interesting things awaits us ahead. "
In the 6th season, Lord Jon Royce (Rupert Vansittard) will play a more prominent role, only a little bit "dropped" in the 5th season of the Games of the Thrones. The actor himself officially confirmed that he would return to the 6th season - and, moreover, the scenes with his participation would be filmed in July and December 2015. However, of course, Vansittart does not even represent that the scriptwriters have prepared for his character - and whether he will no longer reach his head in the first episode.
Separately, we note that David Natter did not mention the word about the fate of John Snow, although it willingly confirmed the death of other characters. Holds to reflections, isn't it? :)
