Well, as some of my fellow dead (WW-wise that is) can attest, I was convinced that
the phantom was the final werewolf based on this basic truism: if he gets killed or lynched by the end of Day 3, he's innocent because no werewolf would want to let him live, so dangerous is he. If he lasts and lasts, he's a werewolf, for obvious reasons. Since both of the werewolves were killed by the end of Day 2, the choices were clearly random, and so the phantom survived as long as he did. So the "truism" still holds. I'll be watching you, phantom....
