Rowling has turned down a lot of proposed Harry Potter ideas—including, she told Winfrey, a musical that Michael Jackson wanted to do. Earlier this year, Rowling announced that she’s working with a team to bring a new Harry Potter story to the stage; Harry Potter and the Cursed Child will hit the West End in 2016.
In a battle between good and evil this epic, not everyone would make it through alive—that would have led to “very fluffy, cozy books,”. “You know, suddenly I [would be] halfway through Goblet of Fire and suddenly everyone would just have a really great life and … the plot would go AWOL.”
Which is not to say that Rowling knew exactly who was on the chopping block. She thought about killing Arthur Weasley after he’s attacked by Nagini in Order of the Phoenix, but instead opted to save him, partly because “there were very few good fathers in the book. In fact, you could make a very good case for Arthur Weasley being the only good father in the whole series.” (She also “seriously considered” killing Ron, then thought better of it.)
Instead, Lupin—a character she had no intention of killing when she began the books—and Tonks died during the final Battle of Hogwarts. “I wanted there to be an echo of what happened to Harry just to show the absolute evil of what Voldemort’s doing,” she said. “I think one of the most devastating things about war is the children left behind. As happened in the first war when Harry’s left behind, I wanted us to see another child left behind. And it made it very poignant that it was [Lupin and Tonks’s] newborn son.”
They both blow out candles on July 31. And that’s not the only influence Rowling had on her characters: She’s said that Hermione is a bit like her when she was younger, and her favorite animal is an otter—which is, of course, Hermione’s patronus. Plus, both Dumbledore and Rowling like sherbet lemons (Rowling said that the wizard’s “got good taste”).
