The cast entered Goa Jomblang. The cave floor was muddy, making it very slippery. Leeteuk had muds entering his boots as he went knee-deep into the mud. The cast arrived at the part of the cave that was dubbed as "light of heaven" because it has a ceiling opening where light can shine through, which created a beautiful scenery. The cast took individual pictures under the light but they were unable to take a group picture as the light faded. During the returning trek, the cast realised that Yunho was being quiet. He denied that he was tired when asked by the worried cast members. In the talking head interview, Yunho admitted that he was experiencing headache, dizziness, and signs of panic attack.
