I personally don't think FFNut is mafia. I really don't want to roll the dice between him and Aerith's Knight just yet.

On the other hand I have reservations about voting Shauna. She claimed vanilla town and no one has counter-claimed her role. This could also be a strategy by one of the people voting for her who is in fact the real vanilla town (Fynn or FFNut). I'm not sure what to make of it.
