With George R. R. Martin's propensity to kill off major protagonists, one has to wonder who exactly has a chance to remain among the living once we turn the very last page and reach the end of the forthcoming A Dream of Spring.
With the author's love for bittersweet endings, I doubt that fan favorite characters such as Jon, Arya, Tyrion, and Jaime will still draw breath at the end. My money is on Sansa to go the distance, much as I hate her.
So who do you think will endure and become A Song of Ice and Fire's ultimate survivor???
