odd bum leer

I suppose it's upto J.K herself how she thinks of her characters. Clearly she would've had an idea of who this person was when she started writing about him, and if she imagined him gay, then that was a facet of his character that helped her create a rounded personality. Whether it came out explicitly in the book would be purely down to the narrative, and in the end there was no reason why it should.
I'm pretty sure she's achieved enough that she wouldn't need to belch this out purely for the tabloid inches.. After all, she just has to finish a book and it's prime time headline super news for a month.
I've read them all out of an interest in popular culture, and I think they're fantastic children's books. Just what the xbox generations need.
