Rowling calls the idea that she had the first chapter of Deathly Hallows written and locked away in the safe “rubbish.” But there was a small element of truth to it: “I had, very early on—but not the first day or anything, probably within the first year of writing—I wrote a sketch for what I thought the final chapter would be,” she told Harry Potter's big screen portrayer, Daniel Radcliffe, in an interview for the Deathly Hallows Part 2 DVD extra features. “I always knew—and this was from really early on—that I was working toward the point where Hagrid carried Harry, alive but supposedly dead, out of the forest, always. I knew we were always working towards a final battle at Hogwarts, I knew that Harry would walk to his death, I planned the ghosts—for want of a better word—coming back, that they would walk with him into the forest, we would all believe he was walking to his death, and he would emerge in Hagrid’s arms.”

And that mental image is what kept Hagrid alive, despite the fact that he “would have been a natural to kill in some ways,” Rowling said. “But because I always cleaved to this mental image of Hagrid being the one carrying Harry out … That was so perfect for me, because it was Hagrid who and took him into the world, and Hagrid who would bring him back … That’s where we were always going. Hagrid was never in danger.”
