Maybe, the only issue it that she sees flames and halos and shit. A lot of the other descriptions I could see fitting into some emotional reading of Kell's 'vision' though. An interesting idea.
Maggot?

that is a sad name for a baby.
Celmoman prophecy specifically dictates that Seswatha's passing is the end of the world, right? So that leads me to a few conclusions.
All of the schoolmen with Seswatha in them die, then the end of the world is neigh. That means, now, that all of the Mandati and Swali would have to be wiped out. Could be possible, but I don't see that happening until golgotterath, Kellhus has big plans for the Swali at least.
Though if that did happen, and then Akka also died, that would be the end of Seswatha.
Or, maybe the baby is Seswatha and will be born about the same time that all the schoolmen are killed, leaving only 1 Seswatha... but that sounds more like a Harbinger kind of thing.
I have no clue really, but one thing is for sure, that baby is going to be important.
