Ah, but another thought:
Not sure why
Nog is bemoaning the bleakness of the scenario like that. After all, the wolves and werebear could very well kill each other, the WQ may be able to kill them, and the ranger's chances of stopping a kill go up every night.
I would say it's extremely unlikely that no baddies will die by night in the next 3 days
and they will manage to kill two innocents per night... at any rate, there are simply too many variables to predict the state of things on day 5.
Maybe you're trying to rally people not to waste the lynch, which is reasonable enough, but painting the situation as nearly hopeless will just demoralize the village.
EDIT: X'd with Noggie.
A pretty far-fetched theory, and one that might help the evil side. I doubt Shasta would fail to make it clear, in that case, which role was responsible for which kill.
