Liz and Peter put together a plan.
Allies Liz and Peter kept their eyes glued on the other Brains Tribe duos that seemed to be bonding around them. In one corner, there's Joe and Debbie. In another, you have Neal and Aubry. Together, the castaways went over their overall strategy moving toward the swap and thought over who would be best to shepherd into their core alliance.
Meanwhile, Debbie saw right through Peter and Liz's plan and decided from a distance and called the quantitative strategist a "prima donna princess" who needed to get the boot.
