Good question. If my internet was working is have my analysis comes tenants and be able to give you a better answer, but alas it is not, so I'm going to have to give you an off-the-cuff one:
If I was to suspend belief about Pizza, my guess is that the wolvès are waiting to atroke because he is "dominating the conversation" (as Llandy and I have been described to do). If that is the case, Ibjave the feeling there is a wolf amazons one of the people who have been saying a lot, but not applying much pressure or shown interest in hunting wolves. Sadly that is quite a few people, but my gut would point towards Llandy ("scratching pole" on Soot and Pizza?), Adaham ("buddying" towards Pizza and odd cases), and maybe Frisian or Vieira as distant secondary suspects.
If I was to still think of Pizza as a wolf, then I'd go with Kronic and someone who has been playing it safer than usual (so still maybe Llandy and/or Adaham).
Sorry for the vague answer, but I have not been able to pay as close attention to the thread as I would like.
