There's no message for Hex unless they attack, but they can't attack without book. Given Gus seemed to be rushing a bit, I can write that off as a clerical error, but there's still a chance Berocka is Coven trying a big brain play (both Mafia visits were obvious to everyone, but only Mafia would know of there were more atm). I also assumed Hayter was just a misspelling of Hatter. Spy is hard enough to fake in AA that I believe him at this time.
