- Ep.12 duel: "Rock Block" - It's the challenge Coach had "done before" in S18: Tocantins, now in duel form. Mike wins easily, breaking 4 tiles with 4 shots. Matt and Ralph both take six throws, so they tie for second, eliminating Steve, who only breaks one tile.
- Ep.12 reward: Mike wins a visit from his mom! Except ... he can give the visit to Matt and Ralph, or ... to the entire remaining Murlonio (Ometepe). He does that, for Bible-adjacent reasons.
- Ep.12 IC: "Step On It" - It's the one where Rob is "literally carrying his family on his back" in 110-degree heat. He collapses at the end, but still gets his necklace.
- Ep.12 Tribal: As threatened since the last episode, everyone wants Andrea out, and so she is, 5-1 over Phillip.
Episode 12 scoring notes
- Duel scoring - This was the first four-person duel, and we will soon need to give people partial credit for third place, but luckily Matt and Ralph tied for second. So both get 0.25 SurvAv/SurvSc points, while they get 0.63 MPF-duel points each (averagd of 2nd and 3rd place).
- IC scoring - Grant was racing up the stairs to place his final plank as Rob won, whereas Andrea was slightly behind both, so they are 2nd and 3rd. Ashley was a distant fourth, but Natalie and Phillip were not really shown beyond the first stage, so they tied for fifth.
Vote count:
- Andrea received 5 votes, from Ashley, Grant, Natalie, Phillip, and Rob (voted out, 5-1).
