Now, while we're on the topic of fanfic, let me complain to you about my current canon/fanfic troubles...
My main problem is that I want to write another demented'verse fic. I have had an opening all prepared (in my head) for the past two-three years... the problem is that timeline-wise, in order to use that opening, it pretty much has to be set in S9. I kept hoping that SPN would give me a good window and plot idea... but, alas, I've got nothing.
So, now my question is: Do I go AU? The last demented'verse fic I wrote was set in S7, so I'd have to catch up that time anyway, and, I think anyone who read my rewatch of S8 has probably realized that I had a lot of problems with the first half of that season. So, on the one hand, this could be my chance to change things a little...
...On the other hand, once you start changing things, where do you stop? How much do you change things? HOW do you change things? Do I still just run into the same problems?
The problem I have with AU, and the reason I very seldom write it, is because working within the constructs of canon gives me limits that I can use to form my plots... and I'm just not sure how good my writing would be without those enforced parameters. Also, going AU would remove the short-hand that I rely on with the readers, where I don't have to explain what Sam and Dean are currently working through, because the readers already know. That's what makes crossovers fun, after all - it's that half of your characters know things the other half don't, and you can have tons of double-meaning dialogue, where the reader is in on all the secrets without my having to explain what those secrets are.
Part of me is thinking I should just forget it. Put that 'verse to bed. Because if I can't think of a plot that fits, maybe that's just the end of it then. But, then, another part of me is pissed off because if I was going to end the 'verse, I'd have preferred to end on Seers, Souls and Scandinavians, rather than Brains and Bones, because SSS had a much better ending, IMO, and would have served as a brilliant 'verse ending. I remember struggling with the decision to write Brains and Bones for that reason, but in the end I did... and now I'm wondering if I shouldn't've.
TL;DR: Struggling to write another demented'verse fic. Not sure if I should stick to my canon-nazi ways. AU is a slippery slope.
