Chapters yet to draft: 12, 14, 16, 17
Number of fiddly bits to retrofit: 9
Some of the fiddly bits are one line, others scenelets or multiple-paragraph exchanges. Also, none of those chapters is entirely blank at this point -- all of them have at least some words in them. (There are 18 chapters total.)
Of course, now that I've said that, I will be running around doing errands and probably won't diminish any of those numbers this morning. Still: I can smell it from here.
