Because Dana quit, Tandang now has to sit someone to even the numbers, and the one sitting out will be Abi-Maria, who has now sat over every single challenge in which someone could sit out. Probst take several pot shots at her for never competing, but really it is his fault when you think about it.
The Survivor rules stipulate that players are not allowed to sit out back-to back challenges when they take place in the same episode cycle. But with reward challenges becoming scarce the past few seasons due to Redemption Island and the three-tribe format, we’ve often had just one challenge per episode. Which means teams can keep sitting out the same players over and over. Bottom line: Survivor needs to amend the rules. People should not be able to sit out back-to-back challenges no matter when they take place. Period. It’s not Abi’s fault. She’s following the rules. You want her to play? Change the rules and make her.
