What a fantastically nuanced story! I loved the atmosphere of it, and could picture every moment in Snape's company...the stockings, the alcohol, the corset, the kisses. Perfection.
I love his unrepentant, lying nature. Bless Harry for his naivete! He was a SPY, Harry. He's not going to give himself away easily. I also loved the jealousy.
Plus, there were Irma, Knight's Tale, Pygmy Puffs, and JKR!Ginny! Not a piece misplaced. Well done!
