"Survivor: One World": Balancing act as tribes merge

(CBS News) The two tribes have merged into one on "Survivor: One World," but that doesn't mean everyone is banding together.

The castaways chose the name Tikiano for their new united tribe, but pre-merge alliances influenced who was sent home (SPOILERS).

This week's Reward Challenge came with two prizes - pizza and beer, and a secret note. The tribe, split into two teams (Alicia, Chelsea, Christina, Jay, Sabrina, and Troyzan on the orange team, versus Jonas, Kat, Kim, Leif, Michael, and Tarzan on the blue team), had to slide and crawl under obstacles to retrieve puzzle pieces, which had to then be put together.

The blue team sent Leif - their smallest player - through the obstacles first, which proved to be a terrible strategy choice. The hole he dug to slip under the log was too small for anyone else to fit through - he barely fit through it himself - and ultimately his team lost the challenge.

So the orange team got the secret note, which revealed there was a new hidden immunity idol back at camp. They decided to withhold this information from the other six players, but Troyzan was the one who found it.

The Immunity Challenge involved a balancing act - contestants had to stand on a perch while balancing balls on a wooden disc. In the end, Troyzan scored the win and individual immunity.

When it came time for tribal council, the post-switch Salani alliance stuck to their plan to oust Jonas, whom they thought was the biggest threat among the post-switch Manono tribe. A vote of 10-2 sent the sushi chef home, and made him the first member of the jury.
