I'm pretty sure the end actually was written by the author. Sanderson filled in some of the stuff leading up to the end, but he did a pretty inconsistent job of it.

You unfortunately quit right before things turned around. Some of the best and craziest scenes were either at the end of that book or the next (can't remember which). (edit: It's possible I'm remembering the wrong laundry conversation - I think there may have been several).
