I know i might be the only one, to say its not Uchenna and Joyce, but i think its Romber. The "African American Couple" was heard so i dont think they would be 17 hours behind and still be seen, that would mean it would be late at night right and who would be at those caves way way at night, right, what it would have to be like 3am? Also i think a flight to KL would be easier to get than Mozumbique, right. Romber has already hinted to Amazing Race, so think they loose from a bad flight, to Mozumbique, where it would take them a long time to get a new flight, right? Also why would they let the teams head off to Hong Kong with a 5 hour head start, meanwhile if teams stay in a near African County they race would supply charter flights still being able to controll the teams, while waiting for Romber to come in, 5 hours later.
