In my opinion, Roslin's behavior is simply standard operating procedure for the person who is most likely playing Roslin. Accusing everyone for everything is nothing new. Neither is their willingness to argue with everyone about every point. Even the part about trying to put suspected mafia into teams. Since they always play this way, it does make it difficult to tell when they're mafia and when they're not. I agree with that.

At this point, since I'm pretty sure I know who they are and am familiar with their playstyle, it's not enough to make me think they're scum yet.

All I have right now is the observation I made quite a while back that I find it interesting that Gaius would vote to lynch D'anna for bothering to defend the roleplaying behavior of himself and Caprica. It's odd. I'm not even sure if it would make them mafia. I don't know what to think of it, other than perhaps they're a lyncher?

Not knowing all the possible roles in play certainly makes it a challenge!
