Boingo mentioned that if the book is not followed, bad luck ensues.

I'll be honest, there was so much tension with Boingo's and Hol Horse's plan that I was almost rooting for them, and I even was a little frustrated that Jotaro and Polnareff dodged the bullet (heh). I don't know why, maybe because it was focused on them for the two episodes or maybe it was sympathy for them.
