Ok here are my theories before the season starts.
And yes these are my 100% THEORIES. I don’t know shyt about the last season besides whats in the trailer so here it goes
-Arya waits until after the big episode 3 battle and kills Jamie, takes his face and travels with the Hound to King’s Landing. She kills Cersei and in her moment of triumph removes Jamie’s face to reveal her own so as Cersei slowly bleeds to death she knows that a Stark got their revenge. As she’s staring into Cersei’s face the Mountain comes up behind her and cleaves Arya in half. Arya dies with that look of Triumph etched permanently on her face.
-Arya’s death leads to the long awaited for Gleganbowl as Hound wants revenge for all that his brother has taken from him, including his ward Arya.
-Jon Snow learns of his parentage and is more devastated by it than encouraged by it. He has no desire whatsoever to sit on the iron throne or claim his Targeryn heritage. He tells Dany out of a sense of duty because he loves her. She, at first attempts to NOT let the truth anger or distract her, trying valiantly to trust in her love for Jon. But slowly, tragically, the fact that she is NOT the one and true Dragon drives her slowly mad. I expect the revelation to happen fairly early, by the end of the first episode, and for Dany’s slow decent into anger, jealousy, and madness to run up until the finale.
-As i said earlier, Jamie dies by Arya’s hand. He comes back to Winterfell to keep his promise and tries to offer apologies to Bran, who gives zero fukks as he is now the three eyed raven. Arya being Arya doesn’t forgive and kills him after the episode 3 battle. Her last scene in Winterfell is her going to hug and say goodbye to an emotionless Bran while letting him know she “set the wrongs right” (or some such dialogue)
-The Night King has an old old OLD school beef with the three eyed raven and wants to personally see to it that he dies. The episode 3 battle will be both a large physical battle and a “mind” battle between the forces of good and evil between the NK and Bran.
-No headless resurrected Ned. No Lady Stoneheart.
-Not too sure on Tyrion. I HOPE they don’t make him out to be some simp who “betrays” Dany because she friend zoned him.
-No theories on the Red Witch other than she dies.
-Arya is in fact, running from a Zombified version of her direwolf (not an original theory by myself, i just believe this)
-Jon, Dany, Jamie, Cersei, Tyrion, Varys, Tormund, Qyburn, The Mountain, Grey Worm, Arya, Theon, and The Hound all die in some manner or the other.
-Bronn makes it to the end, but with no Lannister men around, he never gets his castle or fancy wife.
-Brienne, Podrick, Missandei, Bronn, Sir Davos, Theon’s sister, Gendry, and Bran all live
-Gendry sits on the iron throne, bringing the story “full circle” with a Bareanthon on the Throne. He marries Sansa, making her the Queen she always fashioned herself in her youth. Sir Davos becomes hand of the king. Brienne stays on as protector to Sansa. Podrick attains knighthood. Bran leaves Winterfell forever, marking the end of the Stark lineage. Ghost is the only direwolf left alive. The two dragons, without their “mother”’ Dany around, fly away to a fate unknown.
