as an Alia analogue being the case...
But also yes, Alia resurgence would be great.
Except, sadly, on the AMA Bakker was somehow surprised regarding the Qirri/Mimara's baby Spice/Alia connection

Welcome to the Second Apocalypse, Doulou. Apologies, glad you finally made it

Well, the Glossary "head swapping" incident sure seems like a tantalizing clue, but we really don't know what it means, if anything.
Correct. But that combined with the series of deaths, is the stuff of theory legend!!!!!
Honestly - not reflecting any impressions Bakker's given me about TNG, truly in nerdanel territory here - FB makes a great case for Kellhus collecting Decapitants and Malowebi's tale explicitly shows a head being swapped out to no one's notice at least once. Shortly after reading TUC draft (or even TGO ARC) MG even suggested that Kellhus escaped in Ciphrang-Malowebi. It'd be extremely fun to read about Kellhus escaping death - albeit for a time - in the various Ciphrang-Characters he's littered around akin to Seswatha forestalling his own death via the Grasping/Mandate.
EDIT: But to reaffirm, I believe Bakker was more suggesting that, to paraphrase myself, the Ministrate has a scroll that reads "break, in event of my death" from Kellhus. I really want a Ministrate Atrocity Tale at least.
