Game of Thrones is never shy about killing off beloved characters, hated characters, and a lot of horses. Our only solace has been the fact that the show couldn't kill everyone, because there would be no one left to continue the story. That doesn't apply anymore since the final season is upon us, so anyone and everyone is up for grabs.
It's a good bet that a few favourites might perish during the Battle of Winterfell, to up the stakes even further and fuel the survivors' determination to face whatever comes in the finale. But then all bets are off. Who will die heroically in battle? Who will die in the arms of a friend or loved one? Who will sacrifice themselves to save someone else? Will someone come back as a wight?
