December Daily: headcanon

veronamay asks: what's your all-time favourite piece of fanon/headcanon? Describe in detail, including reasons why you love it. Can be something you came up with, or someone else's that you've adopted--just something you really love.

You know what's making me really happy right now? I've been gone from Harry Potter fandom for a long time, but I still sometimes go off into reveries in which Snape actually survived the series and went on to actually have a real life.

Back in the day, there were hundreds of stories on this topic -- I fondly remember some very late ones of dementordelta's. I'm out of touch; maybe people are still writing them.

Sorry -- I'm not really sufficiently fannishly connected right now to have a lot of headcanons regarding fandoms that are still getting new source material, except that I share with a lot of people the absolute conviction of Captain America's bisexuality.
