EvilRoeSlade's emphatic argument that there HAS to be only 2 wolves left sounded kinda fishy to me. I would think estimating that less than 1/6 were wolves is kinda nonsensical. To me, it sounded like a wolf trying to convince people his role didn't exist.
My suspicion is that he is in fact the ursa major and that is why he tried to tell us that it would "make no sense" for us to suspect that role was kept.
