Vivenna and Siri Reunite; Vasher Shows Off His Returned Breath
I believe that this is the first time in the book that Vivenna and Siri talk to each other. (Weird, eh?) I knew I couldn't make their reunion very effusive, since they're both Idrians, and Siri has learned to control herself. Plus, the situation is very tense. (And beyond that, despite Vivenna's coming to rescue her sister, the two were never terribly close. They were sisters, but separated by five years or so.)
This chapter focuses on other things, primarily the changes in the God King's personality and the revelations about Vasher. For the first, I hope they are plausible. Remember, the God King has grown a lot with Siri's help. Beyond that, he's been trained to look regal and act like a king, even if he's not had any practice talking like one. I think he works well here, projecting more confidence and nobility than he really feels, speaking in ways that don't make him sound too stupid, yet still betraying an innocence.
The bigger surprise is Vasher's revelation about his nature. I almost didn't put this in the book, instead intending to hint at it and save it for the second book. The reason for this is that I knew it would be confusing.
The big question is, if Vasher is Returned, why can he give away his Breaths and Awaken things without killing himself?
The answer is simple, in many ways, but I'm not sure if I have the groundwork for it properly laid in the book. (Which is why I hesitated in explaining it.) Remember when Denth said that Awakening was all or nothing? Well, he lied. (I think you've figured this out now.) A very skilled Awakener can give away only part of their Breath. It depends on their Command visualizations. So Vasher needs to always give away everything except for that one Returned Breath that keeps him alive. As long as he has that one Breath (which he's learned to suppress and hide), he can stay alive.
