The other day, I saw an article where J.K. Rowling says she thinks that Hermione and Harry should have ended up together, not Hermione and Ron, and that she may have thought of killing off poor Ron Weasley.
Okkkkayyyy.... I guess I'm glad she said that. Not. I mean, it's her story and all, but first of all, done is done. Secondly, I think the Hermione/Harry matchup wouldn't have worked as well. It was MUCH too obvious. To compare it to Star Wars, Harry was Luke Skywalker and Hermione was Princess Leia. We all know how that worked out. The relationships are similarly based in mutual respect. Likewise, Ron was definitely Han Solo. Not as dashing, but he drove Hermione BONKERS for five books until she realized she loved him, much the same way Han got under Leia's skin. She wrote Ron and Hermione so that they NEEDED each other. Hermione needed someone to take care of and be smarter than, and Ron needed someone to...well, he needed someone like Hermione.
Ginny was quiet, not an attention-seeker, and unexpected in a way. She was perfect, because by marrying her Harry got to really become a part of the family he was already part of in his heart.
And I don't know how to feel about the revelation. I mean, as authors there are always things we'd go back and do differently, but we don't tell readers, do we? Especially if we have readers who really LIKED what we wrote? Does it take some of the shine off of the diamond, knowing that the author sees it as imperfect?
I don't think I'd tell, even if I had regrets later on. If readers love it the way it is, let them keep their happiness.
