"I think there are fans out there who know that too and who wonder whether Ron would have really been able to make her happy," Watson responds in excerpts from the interview printed in the Sunday Times.
Rowling said she could "hear the rage and fury it might cause some fans" of her work and that she hoped she would not be "breaking people's hearts" with her revelations.
Ron and Hermione, she reportedly goes on, would have needed counselling to sustain a relationship the best-selling author describes "as a form of wish fulfilment" on her part.
This news came after an interesting conversation I'd been having with pony book expert Jane Badger on the fourth Flambards book. For those who've not read the series Flambards is a trilogy of books with a fourth volume added over a decade later. In the fourth book the author K. M. Peyton does an about-face and re-arranges the couples who were all nicely sorted at the end of book three. It seems Peyton was, like J. K. Rowling, unsatisfied with the prospects in the marriages she'd made for her characters and went about saving them from 'counselling'.
This leads us into an interesting question: which of fiction's famous lovers do you think were making a terrible mistake, or were victims of the author's personal preferences and prejudices in picking their partners? Are there any books where you'd like to see one half of the lovers marrying someone else?
Much though I love Georgette Heyer I have never been entirely convinced that Judith would have been happy with the over-bearing Worth in Regency Buck - very different to the plausibility of the marriage in Heyer's A Civil Contract.
I could also bang Romeo and Juliet's heads together. Staying with Shakespeare, Beatrice and Benedick remind me of the saying that some people marry so they can carry on the conversation for the rest of their lives and I can see them getting on in a bickering kind of way. I am also driven to distraction by Maggie Tulliver not sticking with Philip Wakem in The Mill on the Floss; simply doing so would have spared us the second part of the novel!
Which fictional lovers do you think have made mistakes or are unconvincing?
Browse my stock for works on the novel, or Shakespeare. For novels by Georgette Heyer, try Mike Sims. For works by K. M. Peyton such as the Flambards trilogy try Aucot and Thomas, Peakirk, or Stella and Roses.
