I do have this sensation that Art/JJ were eliminated in Tokyo, Laura/Rupert were eliminated in Laos, Leo/Jamal were eliminated in HCMC and then there was a NEL that would leave everyone else left in it. I'm definitely suspicious of the gap in time between Tyler/Korey and the rest of them, but I just don't quite think it says enough to make me truly suspect that there were four boots already. I could be wrong, of course, but I think based on everything, I'd say Dubai gave us our 4th boots.
