My take fwiw:
4 teams racing through the desert
Charla & Mirna
David and Mary
Kevin & Drew are the ones that misread the clue so are not apart of the 4 teams racing through the desert
**A roadside confrontation causes one team to give another team an ultimatum. Is this the end of their alliance?
C/M & the BQ's per promo's
**Racing to avoid elimination four teams conduct a mad dash in 4x4's across the desert where frustration and anger boil over and alliances are shattered.
We know that the frustrated alliance is C/M & the BQ's
**Racing to avoid elimination, four teams conduct a mad dash in 4x4's across the desert. Who will make it?
This goes hand in hand with the above clue
**On the way to the pitstop, one team misreads a clue and falls further behind. Is this the end for them?
Kevin & Drew
David & Mary running with the Cha's to the detour:
