There's Still Hope For These Dead Game of Thrones Characters — in the Books

How he dies on the show: In a mutiny led by Alliser Thorne, Jon Snow is brutally murdered when certain members of the Night's Watch take turns stabbing him, believing him to be a traitor. Though there's still hope that he could be revived, for now Jon is pretty dead.

Where he's last seen in the books: As in the show, Jon is stabbed four times by members of the Night's Watch but is never confirmed to be dead. His fate won't be revealed until the release of The Winds of Winter.
