Chapter 3 (confusion)

The thing about Chapter 3 is that I keep rewriting what information H learns in this chapter and how/when she learns them. And that affects how she acts and interacts with K, their ensuing conversations, and so on. And the worst thing is, I've rewritten it so many times that I have trouble keeping straight what she knows at what point. I keep having to go back and reread to get into her head again, and that just stalls me terribly. Keeping notes might be a good idea.
