I have NOT ruined the fandom for you! There is a ton of brilliant fic out there for these two (and sometimes Harmony as well). If you want to read an absolute fandom-wreckingly awesome set of fics, I direct you to The Simple Art of Graverobbing (http://gekizetsu.net/whatnot/kkbb_sn.htm) and it's sequel, Brains are a Nuisance (http://eighth-horizon.livejournal.com/64654.html). But there's more out there! Go! Find it! And then write!

Thanks so much for the praise, though! :)
