Great job with all the little details, the title, mistaken identities, the way Harry read the scorpion's signals, and Severus' POV. I really loved the whole animagus idea, and how Harry was so determined to keep the scorpion, even with everyone else protesting.
The kiss at the ball is an image I think I'll always remember (even though I knew it wasn't really snape). I so wanted Harry to find out what kissing Snape would be like. *sigh*
I felt a little bad for the way Ginny and Molly were painted, but the Snarry was wonderful, and that's what we're here for, right?
