Also, we don't know how Returning works or if a baby can Return. I would think that Returning babies scattered throughout the empire would be difficult to cover; anyone with that much BioCroma will be difficult to cover up or move unnoticed.
Maybe this was hinted at when Siri was thinking about how the priesthood was timing things. They could have already found a returned baby (if they are that rare, say, 1 every 50 years, would make sense.)
I don't like "Seb"... "Sus" works, makes more sense. Or maybe, "Kingie-poo"? Heh heh.
One thing I would 110% love to see: the red painting! Lightsong needs to have kept that painting (as previously mentioned), and after the dream in the last chapter, he should run back to it, see something... This is the point in the Brandon-style that we would all stay up all night, ans 1 layer after another would be revealed. But with this work, I feel a little more left in the dark about a lot of things (which may or may not be good). But that could also be because of the 1 chapter a week format (but, I admittedly ready the first 30 chapters all at once, 2.0 version).
I agree with MattD about the comparison of the women in Warbreaker to the women in Elantris (or even Vin from Mistborn). The main characters of this book seem to be the women, but only Siri's growth seems real to me, and even then, its not too much. Her forced isolation really stunts what her character could do. Technically, she could have almost unlimited viewpoints of the Court of the Gods - even the priest hood would have had its spies (or even the Pahn).
Speaking of comparing books... the one common theme in Elantris, Mistborn, and Warbreaker seem to be a theocratic repressive government/military force bent on control. Hathran and his forces, the Steel Ministry (the "bone-monks" are easy to compare to the Inquisitors), and now the God-Kings priests (although, we really don't know a lot about them, they could be "good"). Not to hijack this thread, but, EUOL, was this intentional in this book? Or did the whole idea of the Returned-Gods/Priest religion kind of evolve?
I want to say this subject is the most important in Warbreaker, but its underdeveloped (mainly because of the main characters limited viewpoints and access to information), at least, as a reader I feel it should be the most important.
