I know. It turned out that annotations gave me a perfect excuse for it.
I'm almost done reading them (I started reading the MB1 annotations right after Part Two ended, because I'm having one of my friends read Mistborn for the first time and he said the army dies in Part Three. That's how I could search for it so quickly. Also, my friend loves Mistborn
), I'm on chapter 38 part-two which is the final battle, so to speak.
Even though we know this already, here's a nice little annotation to show that we aren't insane:
You were probably expecting Marsh's return--at least, you probably were when you read the chapter where he 'died.' Making Inquisitors via Hemalurgy requires killing other people (see book three for an explanation of the process) so there's a lot of mess involved.
Just to show that sacrifices are indeed integral for it.
EDIT: Furthermore, in the same annotation:
By the way, the mists getting pushed away from Vin and Kar here is a clue of some sorts. Inquisitors push away the mists, rather than attracting them, when they use their powers. I'll explain this in book three too.
He says "powers", not "Allomancy". Interesting...
