I personally think that Mijzelffan is more town than anything, as a mafia wouldn't really be crazy enough to draw that much attention to themselves Day 1 just to confirm their own role -- most mafia would stray away from getting flak, especially so early. It would probably only be inexperienced players who would try doing it on purpose, and Mijzelffan isn't at all inexperienced. A check on Mijz would be wasted at this point as far as I'm concerned. He's proved himself as a doublevoter (or a secret voter), and he's put himself under a lot of scrutiny for a mafia player, which would only benefit him if he was the godfather. Since he would come up town one way or the other, what's the point in checking him? Surely any mafioso that is NOT the godfather wouldn't try doing what he did, because they'd be revealed as mafia almost immediately afterwards.
