One more thought before I return to work, fitzy will likely be the mafia's target, right? Even if the doll is alive, the current holder won't have a known inno to pass it to and a new chain of passing would have to be started.
I've been thinking about this for a while. Let's say Vikes is mafia. He knows that if Cubs passes him the doll, it will be discovered that he's dirty at some point. If he was mafia, I would imagine that he would claim to have gotten the doll today and come up with somebody else to pass the doll to. Fitzy? KC? Doesn't matter. He eventually would be found out.
Instead, he's actively proclaiming that he didn't get it. This doesn't seem like something mafia/zombie would do, when he could have simply not requested the doll in the first place.
I'm leaning innocent here at the moment.
