Hmm, my recip only gave one prompt for the pairing we matched on, and it's for a super specific AU. I've never really written an AU like that before - people who regularly write AUs (think, high school or coffee shop or something like that...) how do you go about working out what the plot should be? I'm usually a 'take this hole in canon and fill it' or a 'canon ended, what happened next?' kind of writer...
