As spaceman just stated, No Lynch is a horrible idea.
I do find SouthernKing to be suspicious, especially since despite that he's stated he's on vacation in Switzerland he's clearly checking in and has posted elsewhere, but he does this a lot.
I also find JoanK to be suspicious. He's also acted pretty derpy and didn't do much or even vote much until Jarrema came under fire, then he started posting weak defenses of him until the end of the day, when he suddenly pulled a 180 and voted for him. Seems too much like a bussing. And if JoanK is townie, it makes sense if what JoanK told us about dukedom is true, but that's a big if. Otherwise it just seems weird.
Plus, Jarrema was first to vote for the Duke spots on Day 1, and voted himself on JoanK. Surely a mafia wouldn't be so brazen as to pull that, but mafia have done weirder things.
Plus, I have an out-there theory that JoanK and Jarrema started out as town, then became mafia upon being voted the two dukes. I know it's crazy, but it just seems too plausible for me to discard it, and I actually think it's the most likely game setup if JoanK actually is mafia.
Half of my gut is saying it has to be SouthernKing, and the other half is saying it has to be JoanK. I'm 99% certain it's one of those two. If it's Darth Feather, I'm going to be kicking my self for falling for his fake lurker move, and if it's Nintz, then I simply have to give Nintz a round of applause for an excellently played game; I don't see how he could be anything but town at this point.
