haha, I'm sure there's plenty of typos like that or missing quotations at the end of a piece of dialogue. I haven't line-edited that far but I imagine they're prolific, especially around the climax. That's when I'm free-writing like a mo-fo and giving no real thought to much else than just getting the words out.
Well, the story's solid as-is; but I can and have (I think) given it more depth in these early stages of the rewrite. The changes are mostly minor, but a couple of them are pretty major. They don't affect the outcome or the fundamental plot as a whole, but they add a good bit of authenticity to the characters' experiences, emotions, and conflicts, and, hopefully, to the reader's experience as well.
