The intersection, if it happens at all, probably happens right at
or after Taipei 101. That sighting places a time constraint that is in opposition to expected flight arrival times (esp for TK & Rachel).
So, I'm just thinking that there would not be time to have the Intersection board arranged at some other cluebox prior to the 101.
The mystery to resolve is how TK & Rachel manage to get to Taiwan customs at the same time as the other teams. Maybe there is the Asian equivalent of Polish Air and the flights will be discovered which make it possible after all. That and a truncated Pit Stop would do it.
The fact that Jenn & Nate seemed to have to wait for the next team to arrive may have been a production-imposed edict in order to get side-by-side competing team shots. Maybe a time credit or penalty was effected by this mechanism?
I think the title quote goes to Christina. Red Devils has the Christina way of speaking down pat. So, if the Intersection is after Taipei 101 then they loose the footrace with TK & Rachel. And if the Intersection is at Taipei 101, Ron & Christina could be eliminated another way after being Intersected with Don & Nick.
Remember how Dustin & Kandice tried to hide for a while from Charla & Myrna?
