Can we group the teams into arrival/bus groups?
In this shot, we can see Niroo (India) stands next to A.D. & Fuzzie (Singapore). Niroo is wearing a yellow tank.
Sam & Vince (Hong Kong). Kapil & Niroo (India) are in the background at a bus stop in Chiang Mai.
A.D. & Fuzzie (Singapore) catch up to Sam & Vince (Hong Kong)
Now Natalie & Pailin (Thailand) are right behind Kapil & Niroo (India) at the same bus stop.
Therefore, Kapil & Niroo (India), Natalie & Pailin (Thailand), A.D. & Fuzzie (Singapore), Sam & Vince (Hong Kong) are on the same bus.
I guess this is the last bus.
Earlier we saw Kapil & Niroo (India), A.D. & Fuzzie (Singapore), Geoff & Tisha (Philippines), Ida & Tania (Malaysia), Sam & Vince (Hong Kong) at the bug eating task.
So maybe Geoff & Tisha (Philippines), Ida & Tania (Malaysia) are on the last bus too.
A.D. & Fuzzie (Singapore), Geoff & Tisha (Philippines), and Sam & Vince (Hong Kong) are the only team that didn't get a chance to change their clothes. Therefore they should be on the last bus.
Since Ida & Tania (Malaysia), Geoff and Trisha (Philippines), A.D. & Fuzzie (Singapore) were spotted in another country.
It's a battle between
Kapil & Niroo (India), Natalie & Pailin (Thailand), Sam & Vince (Hong Kong).
