Sounds like another single-boot episode. So the boot should come (solely) from the tribe that does the worst in the immunity challenge. And the last-place teams there appear to be Aitutaki and Manihiki.
   CBS also claims that, "Thursday, a romance revealed at Tribal Council leaves Jeff speechless." That leaves two tribes as prime candidates for tribal council attendance: Rarotonga, whose Candice-Adam pairing was showcased in Ep1, and Aitutaki, of whom Darnell1980 says "JP had something goin' in his tribe with one of the ladies, and that happened during filming." (Later hints further in the thread suggest that's Cecilia).

   So which tribe is it? Rarotonga makes some sense: the editors spent a lot of time (and the episode title) highlighting Jonathan's frustration with Jessica/Flica for losing the chickens in Ep1. And they also took the time to show the "romance" on that tribe, a theme that will be brought up at Tribal Council, for whichever tribe attends. The only problem is, Rarotonga seems to be challenging Puka Puka for a late lead in the one challenge shown. That and the Raros seem to get their chickens back. So while Flica is a possibility to have her flame snuffed, we'll entertain other options.
   Then there's Aitutaki, who were made clear since the post-Ep1 preview to be contemplating throwing the immunity challenge, in order to boot Billy. And Aitutaki does appear to be lagging in the obstacle course challenge, which we think is the IC. And they have a rumored intratribe romance. Sounds like all the pieces fit. We heard this week that Billy did not appear to have lost any weight while on the show, so he'd be our first boot choice. The other option would be one of JP or Cecilia, the rumored romancees. But we'll go with Billy.
