From the promo screencaps...
PURE SPECULATION: I THINK Tammy and Victor are first... Tammy looks quite blossoming with her smile and the daylight seems to be so early still...
I THINK Jaime and Cara are lost at the same time while Tammy and Victor are in the eating roadblock.
I THINK Kisha and Jen and Margie and Luke are fighting for last place...
I THINK There's only one Travelocity Gnome... or they needed to exchange it for their next clue like Auckland leg last season.
This is for the fun of it all...
Luke looks so much happy having make up on and the chinese opera costume on his face! Just look at him in the screencaps!
SPOILER/SPECULATIONS
THUS, patterning it to the spoiler that we had last time...
Jaime and Cara were talking about a fighting third team to Margie and Luke = Tammy/Victor whom is probable to have an edge over the others because of that footage...
Margie and Luke arrives last at the airport for the final leg, does not see Tammy and Victor fight or brush off each other, while Jaime and Cara sees them though, and they tell the story to Margie and Luke. It also makes sense that they get ahead of the others at JAL and eventually landing with Phil and BVM. what happens next... you gotta watch the finale!
