She'll die. Brienne is one of our favourites and it truly destroys us to even think about her dying, but . . . she's going to, y'all. It's inevitable. After achieving her lifelong goal of being knighted (by Jaime, no less) Brienne's huge smile seemed to say it all. The preview for episode three features the fearsome knight leading the charge into battle against the White Walkers, so we know that her death — while gut-wrenching — will at least be a valiant one. (We'll riot otherwise.)
