... Chapter 6. Things are getting a bit meta, as Thursday enters the text of Jayne Eyre.
When I first read this book, I hadn't read Jayne Eyre. I still haven't, but I do know a little bit more about it now.
This chapter introduces a very important idea. That books can be interacted with. Not normally during the main plot, but at the fringes. Incidental characters spend a lot of time doing nothing, and are more than happy to chat with visitors.
