Celia Winslow appears in The Signs in the Silence.
Celia and her husband Hugh lost their daughter Samantha when she was three years old, but never gave up trying to find her. Eventually Samantha was discovered by the Jeffersonian team living under the name 'Amy Shenfield', when she attempted to get away from her 'adopted' parents and ended up killing Duval Price in self-defence.
After the Jeffersonian team determined that 'Amy' had been the victim of brutal abuse since she was three years old, they were able to prove that the Shenfields weren't her real parents and track Amy to her true family. The team subsequently arranged a reunion with the Winslows and 'Amy', with Celia signing to tell Samantha that they had never given up looking for her, and offering her the pink stuffed bunny that had been the first thing about her parents Samantha could remember. Once she saw the bunny, Samantha ran to her true parents to enjoy a tearful reunion.
