Mary is disappointed by a charismatic false preacher with splendid eyebrows, and Evelyn is disappointed by a globetrotting infidel cousin of the Priest connection who turns out to be just as condescending as any upstanding Presbyter of them, in

The incident of the false Baptist is plucked wholesale from memory of a similar incident in The Journals, volume I. LMM's judicious phrase was, "The fifteen-year-olds went down before those eyes like ninepins."
The incident of Dean Priest being a condescending douchebucket is plucked wholesale from everything Dean Priest ever said in canon. The sentence "After all, all other beauty is only a background for a beautiful woman" appears in Chapter 4 of Emily's Quest, in the context of Dean stealth-insulting Emily's writing for the 900th time.
