In this week's episode, we hear of Rachel and Emily's long-awaited first day of trekking the world-famous Inca Trail, led by what might be the world's surliest tourguide. We also hear about the terrible realisation that results in extreme rationing of photo taking, the truly incredible camp site in which the pair spent their first night, and the astounding and unsettling lengths to which they will go to befriend any figure of authority.
