My most plausible mafia team is pops, Grujah, Green Opal/Axxle2.
In this scenario, pops tells the two newbies "Stay out of the way, I'mma take charge of the town and then we'll control their votes." (Not saying he's succeeded at this, but there's evidence of him trying to assert himself as an authority and steering the votes.)
Then Axxle replaces in and, as a non-newb, feels more comfortable talking and pops say "fine, I trust you not to give us away."
Grujah has disappeared lately, but before he disappeared he always seemed to pop in to push a wagon along with a vote.
I like this idea because it's the only thing that adequately explains the long periods of silence, the feeling that no wagon has enough push on it to be mafia-driven, the lack of much scummy play on anyone's part. Not so much this exact pairing as the notion that our mafia is 2/3rds lurkers, which would explain why it feels so damn invisible.
I need to look through the long backlog though and see if I can find any hard evidence of this. I thought I'd just throw it out and see if it strikes anyone else as plausible.
PPE: Actually, given that our Doldrums coincide somewhat with Dsell's absence, could that be evidence that he's on the scum team? I keep forgetting about him, which is never a good sign IMO.
