After returning from Earth (via the communication stones), Col. Young is somewhat depressed as his wife asked him for a divorce. He's drinking heavily and begins to have a recurring dream where Destiny is attacked by the aliens they had earlier encountered. They are demanding Chloe's return and in the first few dreams, his refusal to do so leads to Destiny's destruction. In a later dream, he eventually relents and hands Chloe over to them, leading to a major confrontation with Lt. Scott. He is convinced that his dreams are a premonition but Dr. Rush has a different interpretation. As well, Rush still hasn't told anyone that he now has complete control of the ship. Meanwhile, Eli may have found his soul mate when one of the Lucian Alliance members shows an interest in his work.
