This is SO well done, and it's a treat to get two fascinating femslash pairing explored in a single story. The similarities between Marge and Umbridge are startling once they're pointed out and I liked seeing Dolores' inhibitions about it gradually recede. By comparison Millicent and Myrtle seemed like a conventional romance, which is quite an achievement given that one of them's a ghost, and I adored the descriptions of how Myrtle pranks the people bullying Millicent. Best of all was the way you drew the two stories together at the end. I really enjoyed it!
