AN UNEXPECTED TWIST CHALLENGES EACH CASTAWAY'S COMMITMENT TO CURRENT ALLIANCES, ON "SURVIVOR: COOK ISLANDS," THURSDAY, SEPT. 28

"Flirting and Frustration" -- An unexpected twist sends the castaways scrambling for new alliances, on SURVIVOR: COOK ISLANDS, Thursday, Sept. 28 (8:00-9:00 PM ET/PT) on the CBS Television Network.

Having sized up her tribe, a giddy and flirtatious Parvati starts using the only strategy she knows to manipulate the men and draw them into her "web." Jonathan quickly grows frustrated with Jessica when he tries to talk strategy and she seemingly wants nothing to do with "playing the game." Nate shocks himself when he scores big while spear fishing and brings back enough food for the entire tribe. And, the third castaway is voted off the island.
