Forget about lynching and think of the possibility that there are werewolves, serial-killers, and cops and roleblockers and vigilantes possibly doing things at night. Meowth if he wants to can simply kill 1 of us tonight, and another one of us tomorrow if he gets lucky. If vulpix gets lucky...he might get one of us lynched...On top of that Meowth also gets a vote for lynching as does vulpix..and although you think you can sway Meowths vote he might have just already decided to change it because it doesn't matter to him but when a vote doesn't matter he'd be unswayable. Meowth is a much greater threat than Vulpix.

extra reason I think Meowth is a werewolf: he has claws... 0.0
