I have the first part of the trouble scene all fixed now, with all the drawn-out introductions very much condensed. And I've smoothed out the ending of the scene, which didn't need much work. I'm still a little fuzzy on what goes in the middle, so I've barreled on ahead and edited the next section, and now am beginning the last scene of the chapter. Once I hit the end of the chapter, I'll go back and tackle that tricky ~500 words.
That's the plan, anyway.
