Lost and Found (S02E23)

Jack and his team try to determine if foul play was involved in the 1991 adoption of 16-year-old Serene Barnes (Tina Majorino) after the teen shows up at the FBI offices claiming she was kidnapped as a young child. When Serene discovers an old newspaper article about a 3-year-old girl with the same first name, who was kidnapped the year she was adopted – 13 years ago – she wonders if her loving adoptive parents may have actually kidnapped her. Serene's story of abduction seems feasible after the team learns that there was a missing Serene Andrews who was never found. Meanwhile, Jack shocks the team with news that he's moving to Chicago with his family. (iTunes)
