Do you know why the Sherlock fandom ships John/Sherlock? They're not paid or anything. They like it. They get off on it. The more intricate the fanfic the more they get off and do you know what? One day just writing fics and drawing fanart won't be enough. One day we'll be standing round Cumberbatch and Freeman superglued together in compromising positions and the Sherlock fandom will be the one who put them there.
