I am legitimately a town neighbor. That means one of you lovely folks is a filthy liar. Based on TheDominator37's and RadiantCowbells's behaviors, I'm inclined to think that both RadiantCowbells and Titus are what they say they are, leaving Fire Assassin. I'm not sure why Fire Assassin would claim 1-shot bulletproof as scum, but then again (1) there's no reason for a mafia 1-shot bulletproof and (2) there's all the reason in the world for a mafia neighbor.
I was going to go "I'd like to read the rest of this game before kaboom," but now that I've written all that, I think I'm going to go big (or go home). Bombs away!
Fire Assassin hates setup speculation, so let's make the fate of this game rest solely upon the shoulders of setup speculation. That'll be fun.
