So, for the final 24, Shane Gould loses 2 points. Dirty Harry gets the 2 points for rallying the votes against Shane, and Lydia gets 1 point for getting her target out without getting any blood on her hands. Lee also loses a point for being so out of the loop that he voted against Michelle.
For the final 23, Jericho loses 2 points. David gets 2 points for leading the vote against Jericho. Phoebe gets a point for being a swing vote and uniting the majority alliance with cookies. Moana I suppose will lose a point for being talked about as a vote and voting incorrectly.
For the final 22, Daisy loses 2 points. Brooke loses a point for wasting an idol. Dave gets 2 points for getting his target out and flushing an idol, Mat gets a point for being in on the plan and using an idol correctly.
