It makes me wonder if the problem or solution is that slash only plays things out that are already in the text, albeit through sex. Okay, I totally totally love this. Because I personally don't give a flying whoop about canon in fic, het or slash. A pairing is interesting, not becase they are so totally doing it and here's the proof, lookit all these hints! but because two characters do interesting things when you put them together and they have to depend on each other or deal with loving each other.

A prime example for me is Ginny. I prefer to femslash her, and not because she's any other girl's canon soulmate. She isn't. I don't really believe in either of the two most common Ginny ships. Ginny/Hermione is cool, but in my heart of hearts I think that R/Hr is canon and that Hermione is attatched. I shipped Ginny/Cho over the three year summer, but then OotP!Cho wasn't someone that I connected with anymore. I don't really ship Gin with anyone. But I like who she is so much better when she's in a femslash environment. She just does incredibly interesting things, character-wise.

I do love using canon details, just for fun, as a shoutout of sorts. But fic, for me, is a way of exploring characters by observing and examining their reactions to character dynamics apart from the ones that we see in canon.
