Can't get any traction in my writing. I've been working on the former GN, but it's like I'm turning a gear where the cogs are worn or broken and won't quite slip into place and make the thing move properly. I've got the middle set up more than I ever have before, but it's apparently not ready to click yet as far as creating its own momentum. Dammit.

What is the thing that's preventing it from slipping into place? Something's in the way, here. I need to try to figure out what it is.
