I don't think something can co-exist simultaneously in both canon and fanon. Once it's canon, it's no longer fanon.

If we were talking about reasonable people, I would posit that there might be a middle-category of "canon states A explicitly, and implies B, and C is fanon", where B is mixed canon-fanon and C, being logically derived from A and B, an even murkier mixed state.

E.g., the Angel episode Dear Boy implies strongly in a visual manner that Angel raped Drusilla, but never states it as such in outright words (or conclusive images). So speaking about that rape should be a mixed canon-fanon discussion.

But, where fanon is concerned, I don't think very many people are reasonable. (*cough* strawberry-scented hair *cough*)

SPN: there's a writer putting up "Drunken Sam" pieces. She posits that instead of drunk dialing, Sam Winchester gets sloshed and writes hate mail to Stephen King. [link]

My mind went to a number of hilariously scary due South places with that.

Mine too!

Another supernatural: someday (never comes) is a fantastic gen story about the life of John Winchester. Oh, it's just beautiful and heartbreaking.

I think the key to fanon for me is that they're the non-canon bits that are mentioned in passing -- as character notes, mood-setting, backstory, or the like. To beat Nutty's example of "Dear Boy" into the ground, Angel raping Dru is so strongly implied that in my mind it's canon that they just couldn't show onscreen. A story in which Dru rather unaccountably turned to Darla for comfort and Darla gave her a tender and sisterly footrub would be (bad)fic, and ten such stories would be drearily derivative badfic that the first fic author would be quite right to be cranky about. However, it's not until there are a whole assload of stories about completely unrelated plots that reference Darla's footrub skills as a way of demonstrating her hidden tender side, that I call fanon.

No such thing as "both fanon and canon".

I've been enjoying the The Msscribe Story way more than I should. It's the (allegedly) true story of the rise and fall of a Harry Potter BNF. Weird stuff.

It's astonishing, isn't it? Did you read the most recent developments, with Heidi8's 'apology' and Angua9's astonishment at the discovery that the email she sent to Heidi 2 years ago, full of evidence indicating that Msscribe was the Becky Sharpe of fandom, had been shown around to others and then ignored? Angua9 has posted the email text in her LJ.

It's like watching a car crash.

And what I'm getting out of it is that fandom is like High School. Inasmuchas there's all this frenzied politics and people having pashes over the Queen B figures, and wanting to be part of their coterie, and getting pissed off about X being friends with Y, and all that shit. And meanwhile I'm sitting oblivious somewhere, reading, while all the crazy dramas are going on nextdoor.

Yep. Just like High School.

It's like watching a car crash.

At first, it was like watching a car crash for me. But then I kept reading, and it became like... remembering the massive pile-ups on the fannish highway, and I was on the edge of it not knowing that people I liked were in some of those crumpled cars.

Everything makes so much more sense now.

I popped over to read msscribe's LJ, and it's a weird sensation when you've convinced yourself someone's a liar--all the funny things she posted about her life (and some were hysterical) looked suspicious.

I did that the other day, ita. It made me hate the internets for a while. And tracking down the story of one of the secondary players (I think sapphsmum or something like that) made it worse.

Oh dear. I think I'm a terrrrible person. I started reading that account this morning and I just got hooked. And didn't go to college. But it's just fascinating. From the outside, anyway. Being anywhere in the actual orbit of the thing must be horrific. The only part of it I'd ever vaguely heard of was the fadom scruples bit.
