OMG THIS IS SO FABULOUS!!!! I've had this delicious awesome happy feeling of discovering one of my new favoritest Snarries - scratch that, *everybody's* favorite Snarries - since I read the title and the summary. Giftiger Lautsprecher indeed. AHHAHAahahaha, that is SO Snape.
And with that summary and bit of German, so obviously one of the gifted (English-etymology, not German LOL) great Snarry writers I always long to hear from. I'd email in a guess, for once in my clueless guess-less readerly career, but I don't know which of 3 or 4 names to suggest. One of those writers who is crackishly creative, impeccably stylish, smoothly deft as a writer, deeply fond of canon and characters. Who unfailingly treats them each - and us - to much loving good fun.
Ahh... fic as it should be written. Snarry as it should end: sweetly triumphant. And a PLANT animagus-of-sorts! This is so going in my Environment-in-HP theme list. If only because it's so good, and when I talk about Env-in-fandom, I want something really good to quote!
