The castaways get more than they anticipated when tree mail arrives.
The added surprise at treemail leaves the castaways to ponder the mystery behind it. One group of castaways hatch a devilish plan to dupe their fellow tribemates. A severe hatred between two survivors leads to serious politicking to get the other voted off. One castaway’s guilt of aligning with a faction is exacerbated by comments from another castaway.
And, the ninth member is voted out of the tribe.
