1) It's going to be hilarious when he doesn't actually set off the bomb, and nearly all the fic out there is instantly Jossed. I may applaud.
2) Have strong desire to write genderswap fic in which John is still named John but Sherlock has a feminine equivalent of his name. It will be plotty and not just a weirdly structured essay on feminism. Sherlock will actually be a sociopath.
I don't know how to write genderswap. I almost never even read genderswap. Is there a manual somewhere? Have any advice? What would I know if I were familiar with the genre? And what can I possibly call Sherlock?
