This week the teams are faced with more frustrating challenges, as the ladies learn how to build a rocket and the guys buy new outfits for the girls. Meanwhile, one contestant goes to great lengths to try and form an alliance so his team won't get chosen for elimination.

The stakes are raised as the guys and girls must work together as a team for the first time in a variety of outdoor challenges, with the winning team securing their place in the final episode. Meanwhile, frustration becomes apparent among the contestants when one requires medical help, another loses their cool and two square off.
