After re-reading this, I did have one question. What happened to those who were "tubed"? Mind you, it doesn't really matter since their pretty much out of the picture, but it could get interesting, especially for Sybil Trelaney when the compulsions kiced in and she didn't have anyone to return to (though I suspect Ernie would not appreciate waking up with the slap makr still on his face and the witches even more powerful than when he was put in there). Still, those are minor and unimportant threads to deal with.

Heya again, Cat.
They’ll be released in the epilogue.
Sybill: Since Harry had Winky deliver the blood to Madam Bones, they will have put it to good use. She will wake up compulsion free. Ernie will have the slap mark. It will heal on it’s own. Mebby he’ll learn to treat woman with more respect.
