Adrian worked out the message meaning, climb the stairs marked G (God's first). This led the male team to the top of the cathedral and a small room furnished with statues of kings and angels. One of the statues contained a clue to the third location in this episode, the fortified town of Carcassonne. Thus, the boys won the first task. At Carcassonne, the teams find a parchment covered in a dead regional language, consisting mostly of French, with hints of Latin and even Greek. However, the key is not the words, but particular letters, which have been pinpricked. Holding the paper up will allow light to shine through, revealing which letters are needed to make the name of the next location. The girls solve the clue quickly, with Suzie having knowledge in Victorian history from where the trick originates. Meanwhile, the boys are left floundering, with Simon and Nat disagreeing about how to solve the clue. The girls work out that they must go to La Tour du Trésau, one of over 50 towers in Carcassonne.

They soon wipe away the surface of the paintings and find letters spelling out Montségur, the fourth location in this challenge. The mountain fort at Montsegur is reached by an arduous two-hour walk which proves too difficult for the male team contestant Alan, who resigns his place in the show and returns to England. At this point, the teams are numerically balanced in terms of personnel following Monica's elimination in the first episode. The boys' morale is left in shatters, but after a team talk, pull themselves together in the hope of regaining their lead. Reaching the summit the teams are required to locate rock-filled bags amongst ruins which they form into an Occitan cross. However, letters on the rocks also require placing in a particular way (inspired by Chinese trigrams), to reveal the final location, the caves of Grotte de Lombrives. The female team is the first to succeed and they arrive at the cave complex, and Alexandra and Saskia find a French message to look for the lady in the rock, actually referring to a rock formation which resembles a pair of women's legs. Despite Simon and Kristian catching up, Alexandra manages
