Spent lunch trying to work through the opening of Chapter 18. Came to the conclusion that I'm going to keep the end of 17 the way it is now. Changing it felt like I was forcing it where it didn't want to go. And once I let it go, I figured out the chain of events to get everything done. Ah, a plan coming together.
And when I let it go back to where the story wanted to be, the text started flowing again.
