Press photos are interesting....first of all, a challenge shot...This looks like the first immunity challenge in Redemption Island 1, where Natalie won it by balancing 3 balls on the tray while standing on a perch....chances are this is the same challenge, or a modified version.
But, are they going to have 2 challenges in the merge episode? Maybe? Perhaps the episode could start out with a merge champagne breakfast/brunch feast. Then an RC, slip and slide, followed by an IC, balance the balls. At least that's what it looks like to me.
Now, regarding the other press images....NO sign of Alicia or Jonas. Christina seen staying close to the power couple Kim/Chelsea. Interesting Tarzan hanging with Michael and Jay....switching allegiences perhaps? Two of Tarzan, one of Michael. Hmmmm, would they ignore the boots in the press images?
