Returning from reconnaissance near an unknown planet, Aeryn appears on board having aged one-hundred and sixty cycles. After warning the crew that Moya is stuck in time, she then returns to the planet, leaving a desperate Crichton to follow her. Years pass on the planet's surface. Aeryn has raised a family and is content with her life, but Crichton is a bitter and disillusioned old man. On Moya, Zhaan and Stark combine their powers to discover that Moya is trapped in a 'Center Halo', a region where time does not exist.
