So there’s variations on this all over the web today. From the Guardian:
JK Rowling: Hermione should have married Harry, not Ron
In an interview with quarterly lifestyle magazine Wonderland… author JK Rowling said Ron may not have been the most suitable beau.
She told the magazine: “I wrote the Hermione-Ron relationship as a form of wish fulfilment. That’s how it was conceived, really.
“For reasons that have very little to do with literature and far more to do with me clinging to the plot as I first imagined it, Hermione ended up with Ron.
“I know, I’m sorry, I can hear the rage and fury it might cause some fans, but if I’m absolutely honest, distance has given me perspective on that. It was a choice I made for very personal reasons, not for reasons of credibility.
Did we absolutely need to see the three major characters married off? I don’t mean they should all have spent their lives miserable and alone. I mean, did whom they marry need to be part of the story at all? Not everybody meets their spouse while still a teenager. Couldn’t it have ended like most high school stories do, when high school ends? Leave a little something for us all to wonder about? (And maybe leave some room for Rowling to return to a grownup Harry later on? Maybe another crisis arises in the wizarding world while he’s working as an Auror?)
