to visit in sequence. Alex is blinded by the pressure to succeed (knowing Saskia, Simon and Marianne are planning to vote her off), and forgets about the poem, heading to the final chest first. Meanwhile, Simon also goes in the wrong order while Adrian wastes time orienteering. As the number of keys in each box decreases, so too do the number of remaining participants. In the final straight, only two keys remain. Marianne gets the first, with Saskia getting the second. The two race for the symbol, and Saskia manages to uncover it first. Inside, she shrieks as tarantulas protect the symbol and runs back, giving Mairianne ample opportunity to steal the symbol for herself. However, she refuses to be so callous, and allows Saskia to come back and take the immunity from the chalice. The remaining contestants take part in the poison chalice round the following day. Though Mairianne hesitates with guilt, she conforms to Simon and Saskia's plan, giving the chalice to Simon on the fourth pass, who quickly chooses to eliminate Alexandra. Mairianne worries that her hesitation might make her friends view her as a potential problem. Episode Six: Peru with an Inca Theme First aired 17 February 2007, Channel 4.

Upon finding the shaman, the teams are presented with a basket containing seven snakes and a map. The map shows eleven locations, one of which (location 6) refers to a street known as 'Seven Snakes' (Siete Culebras). Again, Saskia's fluency becomes a significant advantage and she proceeds directly to that location. However, Simon and Mairianne are unaware of the significance and proceed to visit each location on the map following a "path of logic". Saskia and Adrian arrive at an Inca wall on the street and discover the clue behind a stone with a snake carved on it. The clue leads to Coricancha. Eventually, Simon and Mairianne ask a bilingual priest for assistance and are directed to
