In the second hour, some rocky and intriguing developments confront the crew as they learn to adjust to life on board the Antares, as they find that some past choices, combined with an unknown element in the ship's mysterious Storage Pod 4, lead to a complex web of dreams, desires and illusions that result in a life-threatening crisis.
