Sometime this spring/early summer, Paul decided that he needed to make a few adjustments to the manuscript for The Dark Plaza in light of things the characters told him during the writing of the prequel series, so he’s been making those adjustments in bit and pieces as he has time/mental energy to do so.
He also decided yesterday (I think) that he needed to expand on the last part of the manuscript (a part that could be referred to as the “boss fight” sequence, if one wanted to be flippant and also oversimplify matters), because previously he’s focused on the central thread and nothing else.
So today he wrote three thousand words of new material in the last handful of chapters of The Dark Plaza.
Also, I’m pretty sure that we’ve decided, once and for all, to keep the epilogue. Paul had been going back and forth on that: ‘Will leaving it out make the reader feel cheated? Will leaving it in make the reader feel cheated?’ That sort of thing.
