Lady Vrin/Mad

The Consequent Throes' Consequent
Vrin clearly died... or did she? Dun dun DUN! Just like the other Geister, Loremistress Milvistle, ( also known as and the other mysterious platinum blonde, Jenka) the mysterious Lady Vrin is a favorite topic of fan speculation, inviting wild theories and the occasional epileptic tree. She made all those hacking and choking noises, but we haven't seen the body! Given that this is Girl Genius, there's always a possibility that any character may be seen again. Theories aside, we will almost certainly learn more of her story. Stay tuned.

The Revenancy Controversy
What exactly does being a Geisterdame entail? What exactly do wasp weasels detect? Many readers have a strong intuition that the Geisterdamen naturally follow their goddess, and a wasp weasel would naturally detect any substance from their world as wasp infection, and thus that when Vrin, who has a great deal of free will, is classified by a bug squad as a revenant, this should not be understood to mean that she has been wasp infected but simply that she is "wasp stuff". But there are no actual facts to support this intuition. It could also be that Geisterdamen neurophysiology is about as similar to an ordinary human being's as their external anatomy seems to be. The Geisterdamen could be as small a sect in their world as they are in this one; it could simply be the case that accepting a shk-ma is part of the induction as a priestess.
