I'm thoroughly enjoying watching Kim run the show. To be this near the end and still have a couple of workable options -- F3 with Chelsea and Sabrina or F4 with Alicia, Kristina and Tarzan -- is brilliant. And then to turn the vote against Tarzan by exposing his crap to the others was truly a thing of beauty. Tarzan buried himself with his lame attempt at last-minute strategic gameplay. All the talk about looking into Kim's pretty blue eyes and believing anything she says speaks to a phenomenal social game. Add to that she's the best strategist I've seen in a long while. She still has the HII and next TC is her last chance to use it, so unless she wins the immunity challenge, she'll use it and guarantee her spot in the F4.
The only wild card left is the jury. I'm guessing Kim has had her final speech prepared for a good while, like maybe before she left home for the island.
