She's in a sparky state, maybe even gone full mad-girl mode, expecting rational behaviour from her is unrealistic at this point.

I'm kind of expecting Vipsania to go full rage mode on her for threatening her cat myself. I recall the Foglio's being fond of cats, so threatening a cat is the sort of thing that foreshadows a character getting roundly beaten.

50/50 on Wyrmhaut dying or leaving this place in a state of humiliating defeat. Could honestly go either way even if I would prefer her to be dead. She does have students who need her for a passing grade, and GG likes it's academia jokes, so her being rolled out in an impromptu straitjacket made from a tacky tapestry while ranting about her thesis on the Iram Solis or something would be quite fitting.
