Okay. Let's proceed logically.
The way I see it, it can't be the most obvious person. Because that's too obvious, and then the game would be ruined because we'd all have guessed it already, and we'd all complain about how much it sucked. Since that's what fans do.
So it probably won't be Sal or Skunk'ape, even though that's what we're all expecting. Some plot twist in the end will reveal it to be someone completely different.
It can't be the least
obvious person, either, because we all now know to immediately suspect
the least obvious person. I mean, I was totally shocked to learn that the *Censored* Poppers were actually the rulers of Hell.
So now, I don't know about the rest of you, but I'm going to immediately be guessing that the villain is the least obvious person I can think of; a totally random character, like the Bug or Puddin'head Lincoln.
But that would suck, too, since I'd be expecting it in a way, even though Telltale would have chosen a villain like that with the purpose of shocking us.
Therefore, it's the person we most MIDDLY suspect. Like Bosco. It was totally Bosco. Why do you think he hasn't been around this season? Case closed!
