I'm sort of picturing it now as this hilariously un-self aware place where -everyone- is secretly a vampire or a werewolf or a lizard-person or something, all trying to hide their non-human status from each other.
And that got me thinking of an idea I had for a setting with superpowers, which I may or may not talk about in more depth at another time, but with regard to Twilight I initially just said this:
The basic reasoning being that if it's possible to hide something from the rest of the world so that no one who isn't let in on it knows about it, why not two things? So in Twilight the world at large doesn't know vampires are real, but if that's possible then shouldn't it also be possibly to hide the lizard people from the vampires?
And for a while that was all of it, but for some reason at some point I decided that Jessica should be the lizard person in town. I was also thinking that there should be a weresloth, and I imagined a tragic story for a mermaid who couldn't swim (she was paralyzed from the waist down you see) and thus was thus her family was living as humans. But I didn't put too much more thought into it than that.
Then the concept of werebears came up. (It's worth reading that thread for the mention of werebear carebears alone, and the earlier unrelated more plausible legend for sparklepires is something I also highly recommend.) In response to, "Dammit, now I want the werebear version of Twilight!" I wrote:
And then Ana Mardoll made some suggestions, supporting Angela as a werebear on account of being quiet and cuddly, and suggesting that Lauren be from her favorite Lovecraft story and Jessica be Yuan-Ti.
I responded to the suggestion about Jessica thus:
I note the "usually evil" and I'm not sure if I should place my focus on the "evil" or the fact that "usually" means "not always".
And I think that's about all of it, though I should note that manuscript e from Snarky Twilight, mentioned in the Bible Quote passage, assumes that this is how the Twilight-verse works (where the main text of Snarky Twilight does not.)
