There were many good things about this fic (besides the fact it was well written and witty of course).

1. A rarely seen voice/attitude from Remus. It's always the quiet ones, isn't it? ;)

2. Tonks' revenge in the form of a hex which has a very canon-like feel to it; horrifying to a muggle and very inconvenient to a wizard.

3. Snape. I love how you've written here, not to mention the lovely angst and H/C involving him. My favorite stuff to read. I'm mean, I know.

All in all, bravo!
