Carbonated claimed to redirect beancat to themselves (with no kills occuring) , pushing on beancat to save themselves. Beancat ended up being the starting mafia converter (there can only ever be 2 so we’ve killed 1, if we kill the other evils lose out on conversion for the rest of the game)
if carbonated is a convert it simply would have been better for them to just die than do that. They absolutely could still be a neutral who…for some reason claimed this. But that’s not a likely world.
