Ha! I didn't have any other PLing and I did have a block of time, so I decided to tackle the long chapter! No rush on the notes.
Notes for chapter 11 are below. The epilogue is PL OK. As to what's going on, I think (just my immediate take on it having finished PLing five minutes ago) at the very beginning of the epilogue the nutty professor is coming round and is still pretty woozy, thinking of himself as a specimen. Gradually he realises he is in fact a living and nerdy guy. He asks for a pen and paper so he can write down what he's just dreamt - I think maybe it's hinted that the narrative of the master girl was written down by him. In the prologue he got knocked out when a bit of the cave brained him, and when he started waking up in hospital he was coming back to his old ideas about knowledge (everything is dusty, items go in museums, etc.). But in between, when he wasn't 'himself', he had access to a version of what he'd hoped for, a vision of what life was like back then. Does that make sense? Admittedly the dots might have been joined a bit better for the reader - it's easier to remember the master girl's exploits than the goofy professor from the very beginning of the book!

Just to confuse matters even more than the general pronunciation note, the second link pronounces it ‘Obi’, which is how it’s spelled a few pages later. I don’t know why he used two different forms with at least two possible pronunciations either!
