S1, E5: Emma arrives in Minnesota. She retrieves a photograph of a couple and an address from a lockup of Esther's. The address takes her to a house in which a four-year-old girl plays and as Emma secretly comes face to face with the girl we see they have the same unusually colour eyes, one blue and one brown. This girl is her daughter, Freya. This is the secret Esther has kept. Pete and John attend Esther's funeral to wait for Emma who doesn't show. Emma and Pete confront each other over their suspicions of what the other has done and reach a new accord. Pete explains away the photograph and the eerie items in the storm shelter and there is renewed trust between them. Emma is forced to make an agonising decision - to leave her daughter in Minnesota and to try and win her back through completing her rehabilitation. Pete promises he will support her and piece back the memories she can't unlock from before Freya's birth. Mary rocked by guilt at what she's done loses herself in illicit sex with her younger lover but cannot escape what she's become. A murderer. John begins to exert a new control over her, secretly knowing what she did to Esther. When Mary chastises John for the failure of his plan to find Karen he drops chilling hints about his past. It leads Mary to discover a traumatic rape for which John has never been caught. Realising he has lied to her about the extent of his crimes, Mary is driven to find her own protection against John. Rose, hurt at Emma's abandonment, goes to the cabin to take comfort in this space of Emma's. Instead she finds evidence of Emma's relationship with Tom and the truth about her former identity: Karen Miller. John's meticulous research on Karen sees him spot the telltale sign of her presence at Esher's grave and it finally leads him to her. But, instead of alerting Mary, John keeps this secret and we sense he's going rogue and is on his own dark path.
