Here is my guess on why we see Natalie saying the "worst thing that can happen"....
There is a good flight out of Chiang Mai to Saigon on 5/22 at 1440PM arr 1945. Teams that miss that flight are going to have to wait until the next morning to leave, and it appears that we will have some sort of 5/22AM task (Paintball?) for the racers which may delay them.
A 24 hour Pitstop fits timewise, but does not fit with all the press about shorter rest times, a tougher and harder race, and I don't believe that happens here.
I am thinking that these pictures
are probably taken in the Chiang Mai airport as the columns and windows seem quite similar:
leading me to think that they miss the 5/22 flight and must wait until the AM of 5/23 to fly out, not arriving Saigon until 1030. But are they the ONLY team to miss that flight? Maybe not....
Does it mean they are eliminated? Not necessarily. We have been told that several teams do not arrive to the clue until the afternoon of 5/23. If
the spoiler info is correct, then a M/M team is eliminated in Saigon, and we will have the pleasure of Natalie and Pailin's company a while longer.
