Last night after I gave up, having done a terrible thing, in order to get any words at all (I abandoned Chapter 4, skipped Chapter 5, and started Chapter 6), I was standing in the shower singing "St. Brendan's Way" by Lowest of the Low, and I realized a really important thing about my main character. She's an immigrant. Her parents used to be doctors, back in the old country. I also realized, standing in the shower (EBear said something about plot points being soluble in hot water or something...) that the 500+ words I wrote to start Chapter 6 actually belong at the end of Chapter 1.
I wrote a fight scene.
Unfortunately, when I move those words, I might wind up with a net loss tonight. That sucks.
