 In Season 1 on Leg 5, Paul and Amie were lost in the Sahara desert  after trying numerous routes, getting half of their car stuck in a  ditch, and Amie vomiting excessively. Paul quit, but his partner  didnt and found the desert oasis pit stop by luck, unknowingly  skipping the roadblock and route marker. They were not told to go  back and complete the Roadblock, because they arrived in last place.
