The 18 new castaways began their adventure.

• Marooning Challenge: Each tribe formed 3 pairs. Each pair sprinted down the beach and crawled through a mud pit under a heavy cargo net and then ran to retrieve a heavy chest and carry it back to their mat before the next pair could go. After retrieving all three chests, three tribe members climbed a steep slide to the top of a platform. Using a pole they knocked off a key ring used to open the chest. They retrieved sandbags from the chest and tossed sand bags onto three small high platforms. The first tribe to land all three sandbags on the platforms won a pot, machete, and flint.

Lagi won the challenge. Kyle from Civa and Kevin from Vula were selected to compete for their tribes' supplies.

• Supply Challenge: Following a buried rope that had a machete locked to the end, they used the machete to chop open a coconut to retrieve a key to unlock the machete. They then had to retrieve a pot from the top of a tall pole by any means possible. They filled the pot with seawater and used that to fill a large glass jug to float a key to the top that would unlock a flint. The one who unlocked the flint won the supplies. Kevin won when Kyle accidentally broke his jug. Kyle, in a demonstration of sportsmanship, then helped Kevin finish filling his bottle.

At Civa, Kyle & Kamilla bonded and brought David & Chrissy into a majority, while the whole tribe tried to decipher the meaning of numbers and animal symbols at camp. At Lagi, the men aligned and debated whether to bring Eva (who Joe bonded with) or Bianca (who Thomas bonded with) into a majority. Star searched for an advantage, but her extended absence made her a target. At Vula, Saiounia’s frustration with Mary and Stephanie’s reluctance to strategize led her to align with the men. She discovered a Beware Advantage and, with the help of her alliance, cracked the cypher to earn an idol.

• Immunity Challenge: Survivors raced over a massive net ramp and through a net tunnel. Then one player used a Fijian war club to smash a mask releasing a box with a key in it. The key unlocked a heavy sled that the team moved down a track, then over some sandbags and finally up an incline to the top of a tall platform. Two players then used the pieces inside the sled to assemble a Survivor logo puzzle. The first two teams to finish won immunity plus a large shelter-building kit for first place and a smaller toolkit for second place while the losing tribe had to forfeit their flint.

Lagi and Civa won the challenge. Stephanie was targeted by Saiounia for her puzzle performance, while Mary and Stephanie targeted Saiounia for playing hard early. Kevin and Justin debated turning on Saiounia due to the power she held. At Tribal Council, Saiounia and Stephanie disagreed over their differing approaches to the game. Ultimately, everyone except Mary voted out Stephanie following her failed Shot in the Dark.

Despite Mary being on the outs, Kevin told Cedrek and Justin he hoped to blindside Saiounia. At Lagi, Star found the Beware Advantage and asked everyone except Eva to help her decipher it; Thomas tried to convince Shauhin to ditch the advantage while he was working on it, making Shauhin wary of Thomas.

• Journey: Mary, Mitch, and Thomas went on a journey where they had to solve a timed number puzzle. If they failed to complete the puzzle in the time allotted, they lost their vote. If completed in time, they received an advantage. Mitch won a Block A Vote advantage and Thomas won a Steal A Vote advantage. Mary lost her vote.

Back at Vula, Mary confessed to losing her vote. Thomas told Lagi he protected his vote by not playing, while Mitch told Civa he won a Block a Vote, to Charity’s elation. The other four on Civa searched for an advantage, which Kyle found and Kamilla helped decode, earning Kyle an idol.

• Reward/Immunity Challenge: Starting on a floating platform, one survivor climbed a ladder to the top of the platform and dove into the water to swim under a platform and released two buoys. They then placed the buoys in trays on the platform and then swam under a second platform and then over to a third platform. Once at the platform. The remaining survivors swam in pairs to the first platform and working together, transported the buoys over a balance beam. Once all players had reached the final platform with the buoys, they took turns shooting the buoys into a basket. The first two tribes to finish won immunity and a fishing kit.

Civa and Lagi easily won. Saiounia rallied against Mary, who appeared out of options without a vote, but Kevin continued to target Saiounia. Cedrek alerted Saiounia of Kevin’s plotting, making Saiounia target Kevin instead, though Cedrek and Justin were reluctant to vote out their strongest member. At Tribal Council, Saiounia played her idol to negate Kevin’s vote, while everyone except a voteless Mary blindsided Kevin.

• Immunity Challenge: A caller for each tribe directed the three remaining blindfolded tribe members around and through obstacles searching for three key bags that were used to unlock a slide puzzle. Civa retrieved their three key bags first followed closely by Lagi. The caller then led the blindfolded members to the puzzle table and then directed the puzzle solver, who was still blindfolded, in solving the puzzle.

Lagi and Civa won Immunity with Vula once again having to go to Tribal Council. Immediately following the challenge, Bianca, Justin and Kamilla were then chosen for a Journey.

• Journey: Bianca, Justin, and Kamilla were taken to Monu Island where they had the opportunity to win an advantage. Each of them had to roll seven dice with flames, skeletons and neutral sides. They had to roll until they had either four skulls or four flames. Four flames wins the advantage, four skulls loses their vote at the next tribal. Bianca and Justin lost their vote at tribal. Kamilla won an extra vote.
