On tonight's "Survivor: Redemption Island" Grant Mattos became the fifteenth castaway voted out and was sent to Redemption Island. The episode began with the five remaining castaways traveling to Redemption Island to watch the duel between Matt, Mike, Ralph and Andrea. The challenge consisted of navigating a table maze and then solving a word puzzle. Ralph was the first person to complete the table maze, but blew his lead when he struggled with the puzzle. Mike, Matt and Andrea all finished the puzzle before Ralph, eliminating him from the game for good. Back at camp, Rob and Grant made a plan to get rid of Ashley, but wanted Natalie on board too. Even though Ashley was her close friend, Natalie agreed with the plan since Rob promised her he would take her to the end. The next day the castaways competed in the Reward/Immunity challenge which consisted of using fish hooks to retrieve three bags of puzzle pieces and then using those pieces to complete a fish skeleton puzzle, all with one hand tied behind their backs. Much to the chagrin of the other castaways, Ashley won the challenge and was awarded immunity and a three course meal delivered to camp. Ashley then chose Natalie to share the reward with. Since Ashley was now safe, Rob debated whether to vote out Grant or Natalie. At tribal council, the whole tribe decided to blindside Grant and voted him out.
Four castaways are now left in the game and four more are at Redemption Island. Tune in this Sunday for the big 3 hour season finale to see who takes home the $1 million prize!
