It turns out that the surest way for me to cure writer's block is to whine at people about how I haven't been able to write. My head unfogged with some inspiration around dinnertime, and I got a good chunk of the next chapter drafted. The problem? I think I was in denial about being able to skip ahead in canon. But no, the story really does demand this bit. And so tonight I wrote it, and it even came out pretty well. I think it should be easier to move forward now. Whew.
