Zero, and end of Chapter 4.
I hope you uh, enjoyed it. 8>
EDIT: So there was some confusion as to what was happening in the last pages, mostly which twin was which. Page 79 was a moment when I hesitated in adding or not dialogue to the cannibal twin, and I had decided to keep it "mysterious". But there's a difference between keeping a story mysterious, and making it too hard for readers to understand what should be understood.
So I've decided to go back on that page, number 79, and add in the missing dialogue for a better understanding. I recommend rereading the last three pages :)
