Shots of locks and keys greet us at the challenge. Singers howl. The S10 walk into the challenge in single file, where a visibly agitated Peachy awaits them. He reclaims the idol and says that first, he has to check in with them. He asks Erin if it was difficult to adjust to living together. She doesn't respond at first to Peachy's bait, and says it was much better "having both tribes live together." She then falls for the trap and continues, "I never would have expected our merge to have gone as smoothly as it has." And it's like she just said the "Word of the Day," but no one screams real loud and Chairry, Pterri, and Globey are nowhere in sight. Peachy says, "You said 'merge.' I certainly didn't say anything to give you that impression, did I?" Gong! Shii Devil looks around, puzzled. The others look puzzled too, but clearly Shii Devil's reaction is most important. Peachy points out that he precisely said, "two tribes will live together on the same beach," which is exactly what they've been doing. Ted acknowledges the dangers of assuming, and says he thought they were now one tribe, and that the challenge would be "more of a individual effort." Peachy states again that the challenge is between Sook Jai and Chuay Gahn, because "the two tribes never merged." Gong!
Peachy's moment of revelation having ended, he turns his attention to the challenge. He explains that the island used to be a prison, and that many escapes and escape attempts happened there. Today, the S10 will break out of a "makeshift prison." At this, the camera pans back to reveal two bamboo cages: one purple and one orange. Peachy explains that each competitor will be chained and shackled with locks that "open with a key." As locks often do. They will each have two locks on their wrists, and one lock on their ankles, accounting for fifteen locks in total for each tribe. The keys are located outside the cages on posts, and the goal is to use materials found within the jail cell -- twine and sticks, it appears -- to retrieve them. The S10 must have one foot on the ground at all times while inside the cell, and they can only retrieve one key at a time, which can only be used on one lock. Once they have released all fifteen locks, they will dig themselves out of the cage, crawl through to the front of the cage exterior, and cross the finish line. The first tribe there with fifteen keys in hand wins immunity. Peachy says, "Shall we get it on?" And I've missed his old misuse of sexual phrases.
