*applauds* Great start to the ficathon! Loved the little glimpses into various other characters' lives (like Teddy probably not being Remus's son, and Bill liking both men and women and being a bit of a voyeur, and Molly having been pregnant before she married Arthur -- heh, it's all the sexual peccadilloes that I remember!).
Your Percy is great -- all those cleaning spells, and dividing the room with blankets, and how he charmed his old room at the Burrow. The blind dates were wonderfully awful (I was just as disappointed as Percy that Castor turned out to be married) and Harry was such a lovable dork for coming up with that instead of just telling Percy or showing him that he liked him. Well done!
