WWE Superstar John Cena informs the teams of their next challenge, during which they must barricade their shelters and then retrieve their flags from an opposing team's bunker. In this round of evolution, the winner is not only safe from "The Circus," but also gets a visit from a family member, in what proves to be a very special and surprise reunion. With up to a million dollars of prize money at stake, these competitors will work together with only two options: to persevere and win or give up, "ring out" and go home.
