WIN OR LOSE, BOTH TRIBES WILL HAVE TO VOTE ONE OF THEIR OWN OFF THE ISLAND ON "SURVIVOR: COOK ISLANDS," THURSDAY, OCT. 19

"Plan Voodoo" � Win or lose, both tribes must vote one of their own off the island, on SURVIVOR: COOK ISLANDS, Thursday, Oct. 19 (8:00-9:00 PM ET/PT), on the CBS Television Network.

After a feast is put on the line for reward, the castaways are left in shock when host Jeff Probst tells both tribes they�ll be going to Tribal Council that night. Cristina feels alienated from her tribe after Adam says she is annoying. Meanwhile, one survivor proposes a plan that may expose the hidden Immunity Idol.

And, the sixth and seventh castaways are voted off the island.
