Shifting Alliances on 'Survivor' (VIDEO)

With only six contestants left, 'Survivor' (Thu., 8PM ET on CBS) is heading for the finish line. Everything is up for grabs and anything can change at any given moment.

[Spoiler alert.]

Alliances are shifting on the show, and Rupert is feeling the pressure. Unfortunately, he decides to take out his stress on other people. He loses the immunity challenge to Parvati and suddenly finds himself without a solid plan. So he starts sawing and stomping on branches in the middle of the night, much to the annoyance of the other cast members. "I have never in my life seen anybody that inconsiderate," says Jerri.

In the end, Rupert finds himself voted out at the tribal council. And then there were five. Who will outwit, outlast ... and survive?
