Based on the fact that those six teams have been spotted flying from Thailand to Seoul, we can assume that Sequesterville was in Thailand.
Also, knowing that Twinnies, M/M, and Youtube were eliminated before Leg 5, an assuming that Margie & Luke were eliminated in Sri Lanka, and that the Globetrotters were at the Pit Stop with the Afghanimals, we can assume that the John & Jessica were eliminated in 7th in Rome, meaning that the Globetrotters were eliminated in 6th somewhere between Rome and Seville.
