My observations:
The first spotting of teams in Malaysia is at the airport. Team members are seen running by in this order: Brent, Cord, Caite, Jet, Jordan, et al. When the frame is frozen the first three team members are seen in one frame: Brent, Cord, Caite. Therefore, the first team shown in Malaysia is Brent and Caite.
Teams start and end the Roadblock in the same order they started the roadblock: (1) Cowboys, (2) Carol and Brandy, (3) Louie and Michael, (4) Brent and Caite, (5) Dan and Jordan, (6) Steve and Allie. The teams also check in with Phil at the mat in this same order. Incidentally, and I think that this is the first for TAR the teams check in this time in the exact reverse order in which the did in the previous ep.
The third team to start and finish the roadblock is Louie and Michael.
The team which gains the most spots PERFORMING the detour is Jet and Cord. They were the third team to start the detour (flags) and the first team to finish. So they gained three spots which was the most gained by any team.
The team which loses the most positions PERFORMING the detour is Carol and Brady. They were the first team to start the detour (steps) and were the third team to complete the detour. Therefore, they lost three spots. The other four teams doing the steps completed the detour in the same position they started.
Brent and Caite were the second team to start the detour and the second team to END the detour.
