Arya can’t die. She is meant to kill Cersei. She is also possibly carrying the last Baratheon heir if Gendry dies.
Remember these books are about the Starks and to a lesser extent the Targaryens.
So who goes.
We have to many advisors. Tyrion, Sam, Davos, Varys , Missandei. Missandei plus at least 2 more bite the dust. Davos and Varys. Sam might also because Gilly is pregnant and Sam told Jon his real identity. What’s left of his sorry?
We have to much Muscle. Brienne, the Hound, Turmond, Grey Worm, Jaime, Jorah, Podrick, Gendry. Imho only The Hound survives. Jaime’s work is done. He gave Cersei one more baby, made Brienne a Knight and made peace with Bran. Gendry made Arya’s weapon and gave her love. He’s doomed.
Theon. He is a survivor. Can he save Sansa again and what will it cost him?
Bran: some Stark needs to “die”. What about the artist formerly known as Bran? He is the bait after all and is no longer Bran anyway.
Arya? She has one name left on her list now that she has made peace with the Hound. She kills Cersei. Lives.
Sansa: the leadership of the North is not resolved. Sansa lives.
Jon and Dany. Their romance is un resolved. They live.
Cersei lives for now.
