Have you heard? In a recent interview with Wonderland magazine, JK Rowling said she regrets putting Hermione and Ron together in the end:

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.

Does this change your ship? Who do you ship with Hermione Granger?

Who do you ship?

Either The Doctor traveled to the wrong universe, or it's a coincidence.
