Next week, Tom and Ian think Caryn was lying about the girls' alliance to convince them to take her into their alliance over Katie- seeing as how everyone voted for Steph last night rather than Tom when they had the chance. Tom gets immunity, so everybody votes out Caryn, as per pretty much everybody's plan for the #6 spot, apparently. She leaves having been purely a pawn.
Next week, Katie becomes the swing vote in the Gregg/Jennifer, Tom/Ian alliances, and she doublecrosses her boys to help the lovers kick out Tom, unless he wins immunity- then they vote out Ian.
Final four are Gregg, Jennifer, Katie, and either Ian or Tom. It's all about immunity at this point. Because if Ian/Tom wins it, the situation will be interesting. He would definitely be best suited by booting one of the lovers to break up that alliance, but it would depend on getting either one of them to vote against the other, even if it meant screwing their whole game. They might just rather force a tie, voting for Katie while Katie and Ian/Tom vote for Gregg- then who knows what happens?
If Ian/Tom loses immunity in the final four, they're out, and the final three are Gregg, Jennifer, and Katie- Gregg and Jennifer go to the final two.
Back to situation A- Ian/Tom is in the final three, probably with Katie and Jennifer. Ian/Tom wins immunity, takes Katie to F2. If Gregg is in the final three and wins IC, he takes Jennifer.
So I'd say depending on immunity challenges, we're looking at a win from one of the guys- most likely Gregg or Ian, likely Tom, and also possibly Jennifer.
BTW- Sandra from Panama may not have contributed most to camp or challenges, but I found her an exceedingly likable contestant, and I was rooting for her even from the very first episode- much like Julie from Vanuatu.
