These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Anvilicious: Averted to unpleasant effect, showing how Tropes Are Not Bad. One is led to believe that a lot of the Internet Backdraft regarding Henrietta could have been avoided had the author been much more blunt about Henrietta finding her plans for Louise to be Dirty Business.
Internet Backdraft: Henrietta's thoughts and actions in Chapter Nine have spurred... spirited debate.
The Woobie: Louise is showing competence with her magic and has an incredibly powerful and bizarrely loyal familiar but she's plagued with low self-esteem, thinks she might be losing her humanity, is showing signs of losing her sanity and her fiance is EVIL. Siesta was just a poor school worker when she happened across Louise and Alex. While she's ultimately better for it, there's no question life has been unkind to her.
