Thoughts:
hS is a man on a mission. Not sure I agree with his conclusion on
Form, because I don't agree with
Form on discussing wolf plans preemptively. I suspect if the wolves decide they should sacrifice the NW to activate their powers, they won't particularly care whether or not we considered the possibility. It'll come down to how believable they can make the bussing.
Form's response looks to me more like filling in the gaps after the fact to defend what was initially just talking to talk.
At any rate, dead NW on day one wouldn't be a whole lot of use to the pack unless they have a very good lead on who the gifteds are. Their chances of success increase as the village shrinks and they have something to go on. I can't really see them just sacrificing themselves now, unless they're someone who's generally into that sort of thing.
