Remember, this contest began last week, with four tribes, five members each: Puka, Hiki, Aitu and Raro, as they've come to be called. Last week, Sekou (of Hiki) was the first to go, leaving 19 contestants in all.

Here are highlights from this week's show:

--When Nathan (Hiki) struggled with starting a fire, one of the women on his team did it. The tribe rejoiced as if they'd just discovered fire.

--Ozzy and Cristina (Aitu) debated about the best way to catch chickens in a net. Ozzy's plan worked in the end, and Aitu caught one chicken.

--Yul (Puka) used a crate to catch two chickens in one shot.

--Jonathan (Raro) returned from Exile Island, not having found the Immunity Idol.

--Cao Boi (Puka) relieved another teammate of her headache, using his natural healing techniques.

--Billy's (Aitu) lack of teamwork and initiative disturbed his teammates.

--Aitu members (speaking secretly about Billy) decided to throw the day's challenge so that they could vote Billy off.

--Various tribes used their spears to catch fish and crabs.

--Cao Boi irritated his teammates by telling ethnic jokes and then laughing.

--Puka and Raro tied for first in the challenge; Hiki was next, followed (far behind) by Aitu.

--Aitu sent Yul to Exile Island (loser's choice).

--While on Exile Island, Yul used the riddle to locate the Immunity Idol.

At show's end, as expected, Billy (the lazy heavy-metal man) was the second person voted out. Aitu's strategy--to take a dive in the challenge in order to vote off their weak link--was a risky one, but it ended up working out for them.
