Sundown
performed by Gordon Lightfoot

After a recent spate of abductions of babies from their mothers, Red informs Elizabeth that the "Cyprus Agency" is the illegal adoption organization responsible. More or less coincidentally, Elizabeth and Tom contemplate adoption of their own which fuels Elizabeth to track down the organization's CEO, Owen Mallory (Campbell Scott). Ultimately, the task force discovers the Cyprus Agency's secret: it kidnaps young women and keeps them in captivity as breeders for the babies it puts up for adoption, and that Mallory is the father of all the children. Meanwhile, Meera willingly aids Red in his investigation for the mole. Covertly using Cooper's badge, Meera's intelligence leads Red to Diane Fowler as the ringleader of the leak, prompting him to kill Fowler in her own home. She tells him that she knows about "that day", about what happened to his family. But Red still kills her, responding that he wants to know it more than anything in the world, but he'll find someone else who knows. He then calls Mr. Kaplan to clean up. In the end, Elizabeth finds herself unable to adopt a child as long as her marriage to Tom continues to suffer emotional strain. She is shown frustrated at home sitting in between baby stuff, while Tom goes to see Jolene, the woman who was flirting with him.
