About yesterDay: what I'm thinking is that
Zil and his comrades,
McCaber and
The Unknown Wolf might have thought they were likely to lose him soon, and might even have come up with a plan to bus him. But– as I said
here,
McCaber's death would have been a nasty shock to them, and obviously changes the dynamic quite considerably. So it's a question of whether they would have stuck to such a plan after that.
Zil, at least, gives me quite the impression of someone who would have preferred to stay alive– I think the motivation behind his self-vote was that "it worked for
Rikae", rather than that he was truly resigned to being lynched.
