Maternal Instincts (S01E21)

A court-appointed psychologist approaches Rush regarding a client, Sean (Ashton Holmes), a troubled 17-year-old boy who's been lost in the foster care system since he witnessed the murder of his mother, Rebecca (Tracy Middendorf), 14 years ago. The teen has recently been suffering intense nightmares about the incident, and the doctor asks Rush to reopen the case to finally give Sean closure. As Rush and Valens investigate, they realize that Sean's dreams match key pieces of evidence from the crime. In addition, by contacting Rebecca's family and friends, Rush and Valens learn that Rebecca and Sean were living on the run, seemingly from one of the men in her past. (Warner Bros. UK)
