Here's how it will play out (note: I made everything up but tasks based on spoilers....
Teams leave pit stop in Penang, Malaysia, and are told to take the train to Singapore. During the train ride, the lesbians do something that pisses of the cops, which makes them upset. They form a loose alliance with Brent & Caite, and makes them promise to do the dirty on the lesbians (as in u-turn them).
In Singapore, teams travel to their first route marker (Singapore Flyer?) and pick up their first clue. There is a fast-forward and a detour clue. Dan & Jordan and the cops go for the fast-forward. The cops loses, and have to return and do the detour.
Jet and Cord and Brent & Caite do the drums thing... while Carol & Brandy sell ice cream. Even though it's lunch time, Carol & Brandy have trouble selling ice-cream. To make things worse for them, the cops show up. Brent & Caite finish, and true to their word, U-turn the lesbians.
Jet & Cord have problems finding a taxi. The lesbians accost a small girl, and makes her buy an ice-cream. Job done, they travel via taxi to the U-turn sign. They are U-turned and have to go back and do the drums thing.
Dan & Jordan finish first, and check as team number one.
Brent out muscles everyone at the shipyard roadblock, and they are team number two, but Brent can't find his team's fanny pack (we ought to have one by now)
and says the title. Jet & Cord overtakes them and they check in as team number two! Brent & Caite barely outraces the cops for third place, and Louie & Mike praise them to high heaven for the U-turn.
We cut to Carol and Brandy and they are thus the last team to arrive.
