Here's the deal. Chances are the three baddies will vote for the same person to force a tie (if not get an innocent lynched). If a tie occurs, there will be no death, by which time the third spiderling will appear. 4 baddies, 2 innocents. Game over.
So - not jumping to assumptions here - but say the three of us all vote against
Nogrod. If he's bad, and the three of us are all innocent, the other 3 will all vote against one of us. Of course there's no chance we could convince one of them to vote against
Nog.
But if he's innocent, then they'll most likely vote for him, too.
Gah. What should we do?
