All 20 trainees have made it through to the second stage - where they must make a split-second decision about whether or not to fire in a combat situation. They also face a brutal training session in the desert that pushes some of them to the edge, and must freefall off the top of a 50-foot cliff, trusting a teammate to catch them. This episode also deals with overcoming family tragedy and childhood adversity.

The remaining recruits are tested on their ability to trust each other through a series of tasks ranging from hand to hand combat to a terrifying 200 metre abseil. Shylla is voted the last trustworthy by her fellow recruits, and is pushed to confront why her quiet demeanour makes other people unwilling to trust her, revealing to the DS that a lifetime of racism has made her withdraw.
