While Rob, JC and Charisse were preparing their breakfast, Charisse read the treemail for the upcoming Immunity Challenge.

"Tatagal ka pa ba?
Mga kalamnan matibay pa?
Mga kasu-kasua'y uubra pa?
Sa hamong ito'y nanaising mong matira."

"Parang dehado tayo dito a," Charisse commented. "Parang nananadya kayo a! Goodluck sa 'kin. 'Pag lambitin pa nga lang doon sa Immunity Challenge last time, lintek."

"Hindi. It's okay, andito naman kami ni JC e," Rob assured her. "Si Cris naman. He will surely do his best kasi..."

"Alam niyang siya e," JC said.

Charisse said, "My God, kaya niya nga 'yung four hours sa perch 'no."

"Cris is hanging for his dear life," Rob said.

Back to normal

Minutes later, Cris and Nanay Zita arrived at the camp from their Bangkok trip.

Charisse was ecstatic to see them back.

Cris still had a big smile on his face as he hugged Rob.

Meanwhile, Nanay Zita got down to work immediately to cook the tribe's meal.

JC felt a bit relieved to see Nanay Zita, "Andito na ulit si Nanay. Hindi na ulit kami ang gagawa nito. Siya na ulit nang siya. Okay lang sa 'kin. At least kami, puwede na ulit kami mag - relax."

"Cris, pa-hug naman," Charisse said. "Enjoy? Enjoy? Kamusta si Mommy? Saya? Enjoy?"

"Dude, first time ko lang talaga nabigyan ng saya Mama ko," Cris said. "Hindi mababayaran dude."

"Anong ginawa ninyo? Kuwento naman," Charisse said.

But Cris downplayed his story because he did not want them to be envious, "Nilihim ko na lang ('yung ginawa namin). Nagkuwento nang kaunti."

Even Nanay Zita was careful with her story.

"Kuwento please," JC requested.

"Kumain lang kami ng ano sa barko. Pinasakay lang kami sa barko tapos pinakain," Nanay Zita said.

"Nasa yacht kayo? Barkong malaki?" Charisse asked.

"Yate ba 'yun? Ang hirap talaga ng wala sa bundok Banahaw," Nanay Zita said. "Nanood kami ng sayaw ng Thailand. Tapos pumunta kami doon sa floating market. Si Cris, iyak nang iyak 'yan noong andoon Mama niya. Salamat daw sa pagpili sa kanya."

She thought that Cris was the most deserving to go on the trip with her, "Pareho kasi kami ni Cris na sumali dito, sa lahat kami lang 'yung medyo talagang, ako aamin talaga ako na mahirap talaga ako. 'Yung iba naman naming kasama nasa taas, kaya siya pinili ko."

Cris told Rob, "Mawala man ako o hindi, pasalamat ako kasi hindi talaga mababayaran ang saya ng mama ko. Kahit tanong mo kay Mommy Zita."

Rob also understood that Nanay Zita and Cris were the most deserving for the prize, "Kung mayroon man sa aming lima ang karapat-dapat at mas nangangailangan ng ganoong reward, silang dalawa 'yun."

Balancing act

For the Immunity Challenge, the Castaways would need to balance themselves on a moving platform while gradually adjusting their positions.

During the first 30 minutes, they could hold on to two ropes while standing on the platform. For the next 30 minutes, they could only hold on to one rope. After 30 more minutes, they could only stand on the platform with both feet. For the next 30 minutes, they could only stand on the platform with one foot. They would be allowed to sit or lean on the bamboo posts as long as their hands and other foot don't touch the platform or the posts.

All the Castaways were able to endure the first hour but the second hour proved to be very difficult.

Nanay Zita was the first to slip from her platform after attempting to adjust her sitting position.

Rob, whose back leaned on the bamboo post, also slipped when he tried to shift his body.

After four hours, only Charisse, JC and Cris looked stable enough to last far into the evening.

Charisse, who was comfortably seated on the platform, seemed poised to win. But when she started feeling some pain in her legs, she attempted to shift her position causing her to slip from the platform.

Sacrificing for an ally

Meanwhile, JC and Cris were still balanced on their platforms and neither of them seemed ready to give up.

Cris looked at JC with a pleading expression on his face as if begging JC to give the Immunity necklace to him.

JC seemed unsure if he should give up or not.

But after a few minutes, JC gestured his commitment to their alliance. He put his fist near his heart and stepped down from the platform.

After 4 hours and 29 minutes, Cris was proclaimed the winner of the Immunity Challenge.

Cris was relieved for his newfound security in the game and hugged JC in gratitude.

JC was unsure if he should have sacrificed his chance to win but he hoped that he made the right decision.

Surprise announcement

The Castaways started to settle at the camp and prepared to turn in for the night when Rob made a surprising announcement: "Get ready for Tribal Council."

Nanay Zita was worried because of the swift turn of events, "Hindi kami nag - usap ni Rob na kung ganito ganyan. Wala akong panahon na (magtanong sa kanila kung sinong iboboto) gawa ng nanibago talaga ako."
