You voted for me because I asked about the alliance, and you're not in the alliance because you're crazy right?
I always suspected you were crazy so I'm revenge-voting..
!vote Combine
And I just thought of something. The crazies are the ones who kill people? And don't the vigilantes kill people? That means one of two things:
1) Everybody's crazy, and everybody kills somebody.
2) Craziness changes by round. And if the vigilante changes every round, then that means it's their turn to be crazy.
I win the game.
