ONE CASTAWAY CONTEMPLATES DITCHING THEIR CURRENT ALLIANCE FOR ANOTHER, ON "SURVIVOR: VANUATU -- ISLANDS OF FIRE," THURSDAY, NOV. 18

"Culture Shock And Violent Storms!" -- One castaway struggles to decide whether to stay with their existing alliance or join another, on SURVIVOR: VANUATU -- ISLANDS OF FIRE, Thursday, Nov. 18 (8:00-9:00 PM, ET/PT), on the CBS Television Network.

As the castaway contemplates which alliance to be a part of, a fellow tribe member capitalizes on their indecisiveness to work a plan. A very surreal reward drives one castaway to over-indulge and pay for it later. After a tumultuous night where one castaway struggles to keep the camp together, it is decided the most useless tribe member should be the next to go. Leading into Tribal Council, one tribe member makes a last-ditch effort to secure a power position by attempting to sway a fellow tribe mate. But, will the effort work?

And, the tenth member is voted out of the tribe.
