Great insightful comment. Well as i understand it. We get 7 episodes this season. I believe 6 next season. So there will be 8 seasons total. Or 7 episodes remaining in the total series. Wow don't know about Jamie, lol.. Something about him having a happy ending i dont see, lol.
I do like your thoughts on tyrion. Something about tyrion just says to me he will survive. Wow Sansa and Arya that can go many different directions. Nope the books won't spoil the show, lol. The show is well ahead of the books.
