They had less of a tie to Asia than any of the teams cast, at least.
Why would they pair up Criss and Nhat Anh? Just cast Nhat Anh & Ngoc Anh, they were great.
Were all three previous winning teams at the finish line? I saw 1 and 4's winners there.
Oh, and in response to the person who commented on several legs having the same placements, to be fair to the season the placements shifted in many of those legs and only turned out like that at the end.
