I'm in love with your Galatea Merrythought (but I don't think I'll fight Griselda for her.)
So many great things in this fic, starting with the BAMF witches. And the observations of the attitudes of the young toward the old are spot-on, sad and somehow reassuring in their unchanging nearsightedness.
Loved the Kettleburn backstory, of course, and the cameo by another troublesome Umbridge.
