Firstly, that was a possibility. I didn't know whether or not it was correct. Secondly, this goes beyond thematic analysis into mind-reading the mod. No, he would not have to be third party. Thirdly, why would you even bring this up after Speed already clarified that there is no thematic split?
There is a TP it's right in the OP. Because prior to speed revealing there is no thematic split it would have been by far the most reasonable assumption for Zemo to be mafia/TP.
And idk if you've been explain this before but in a game of mafia everybody is GUILTY until proven innocent, and someone who's even 40% likely to be scum is more likely than average and thus is a good lynch target. So there would have been no reason for you to defend him unless you had inside knowledge.
Or I could just think that no one possibility was more likely than another, so there was no thematic basis to use to reach conclusions about Grey's character (which is what I thought).
Which is totally unreasonable hence why I FOS you.
There's still an interesting contrast between this game and that one. In DP1 of the MCU Heroes mafia, several players assumed that the villains would be scum, until Speed clarified that there were no villains and no thematic split. Sounds familiar, no?
I just opened up DP1 of that game, speed says right in the OP that there are no villains, there is no theme split, and all the players are heroes. He doesn't say that in the OP of this game. So in fact the absence of immediate clarification would have been evidence to the theory that there IS a thematic split this game.
