The voting eliminations have to go. Jet's caught in a logic loop. Oh no, the fish don't do anything because the rules don't matter, they need to have agency! Let's let them pick who to eliminate! Oh, no, they're going to eliminate the audience's favorite, so we need to give them immunity! Oh no, they couldn't vote out the best fish, so they voted out the antagonist! Let's just bring him back since the person we thought was going to be eliminated walked out!
So now Emma won the tree challenge, won the social challenge, won the plant matter challenge, voted out Bashir, and earned nothing. She's actually in a worse position than she would be if she hadn't participated in the challenge at all. James, who won the social challenge and took second place in the plant matter challenge is also in a worse place than he would have been had he not participated. They both now have targets on their back: Emma for shooting Bashir, and James's double crossing of Bashir is probably going to be revealed eventually if it hasn't already.
So now we're back to the beginning of the circle again where the fish have no motivation to participate.
