Damn, I'm going to have to claim responsibility for the DroZ death.
I'm Two Face, a town cop. However, after rereading my role PM more carefully, I finally understand the mechanic. Every night, I choose a target. As is true of my character, I flip a coin. Half the time, I investigate them. Half the time, I kill them. This must have been one of the times I killed them.
Now, since I replaced, my Night 1 result was an investigation on nagerous and that came back guilty.
Given that half the time, my role is a killing role, I think I would be extremely underpowered if I was also paranoid/insane. And if we want to talk flavor, the Harvey Dent side of Two Face has been shown to be a good person, at least in the comics. I had originally assumed that the warning in my PM about 50% being bad would be that the 50% would give me a bad investigation. But now I see it's a 50% vig kill.
Therefore, I assume my investigation side of things is true.
