My thoughts:
1) I cannot figure Alen out yet. He always plays the same way, whether he's a G or a C, so reading his posts, especially in the first day rarely if ever gives you an indication of his role. The only thing you need to watch out for is his voting, especially come the end of the day. But because he was in jail yesterday, its hard to figure him out. No idea yet.
2) Klin is hugely suspicious to me. Anyone whose seen Klin play in previous games knows that as a C he's influential, he makes a lot of accusations, is very active and changes his votes quite often depending on peoples behavior. Yesterday he was content with making an early random vote to Soren, and keeping it that way as if he is trying to steer clear of suspicions. He reeks of a G to me, the only other option is that he has a special role and is trying to be low key, I cannot be wrong about this.
3) Salvo is another who is very suspicious to me, he has played the game so many times yet whenever he's a G he keeps playing dumb and asking silly questions. Also his voting yesterday was very random, and his posts made no sense, he voted Zach at the end. He's suspicious to me.
4) Osman is quiet, I don't like it, he made a random vote for X yesterday. that being said, i'm sure he'd be a lot more interested in the game if he was a G. Not making a judgment on him yet.
5) Zach is a huge mystery to me. The way Janna was left to get lynched yesterday, kinda makes me think theres a huge possibility zach is a G too.
6) Fresh is also suspicious, but only if Zach is a C, he tried to save Janna in the last minute, but was a little too late. It seems to me his G buddies might have kept pming him urging him to change his vote before it was too late, but to no avail. Been there done that with lousy G teammates in the past
I'd go for one of Klin, Fresh or Zach to be honest.
