I was pretty sure it was Kincaid even at the end of Changes but I was completely blindsided by the fact that Harry set it up and then had Molly hide the memory.

And I did quite like He Who Walks Behind; I also really liked that we finally got more details on what happened that day. Poor Harry. (It had really good scenes! But then it had not so really good scenes and some that were just boring. I skipped over most of the Nevernever fight, except when Evil Bob came out to play.)
