This is a nightmare scenario. I think All Might has to be an SK because nobody else flipped with a killing role recently that I remember, so there is that (and I'd hope he didn't use the factional nightkill on scumbuds needlessy to maintain his fakeclaim). Also I'm realizing if we are at 2/1/1, even if we lynch the Mafioso today, we lose because All Might will shoot and gain parity. Likewise, if we lynch All Might, the Mafioso will probably just shoot finally and win the game.
This considered, if we are to believe the gamestate currently stands at 2/1/1, I'm failing to see how lynching today is beneficial. I think we should no lynch and force the Mafioso to shoot the SK to prevent an SK win.
An attempted coordinated nightkill that I'm going to pitch: All Might shoots Silver, if Silver isn't the last Mafioso than it's Pen, like I mentioned earlier, he's forced to shoot the SK or lose because he has a 50/50 shot to win, depending on how Rubik will let this play out. If he sats parity is reached, Mafia wins, good for them. But... Minish never moved her vote off Pen back on D1, Parity technically isn't reached, I could go into one last day phase and Maj vote Pen by summoning Minish's spirit.
If Silver ends up flipping red, none of that matters, Pen and I Maj All Might for the win.
These are all pretty complicated scenarios, the easy scenario is just lynching All Might and hoping he isn't an SK. Oddly, the easy scenario seems the most risky to me.
