Part 3/8:
As Adam explores, hopeful that the sound signifies life, he encounters a frightened primitive boy who warns him of the dangers nearby. This boy is soon captured by a group of women, known ominously as the "snakeheads," leaving Adam with a foreboding sense of the challenges ahead. Shortly thereafter, a powerful earthquake rocks the planet, further complicating their mission as they try to reconnect with Jake, who is managing the geoscan in the safety of their downed ship.
