Lucy Wieder (played by Cara Jedell) was the daughter of Dr. Robert Wieder and Nan Wieder. She feared for her life after Orell Peattie killed her grandfather, Irving Thalbro, and her mother with the intent of destroying Dr. Wieder's family and Wieder supposedly did to his. Lucy and her father were sequestered with Agent Scully for safety, but Peattie found them anyway. Throughout the ordeal, Lucy was the only member of the Wieder family to remain physically unharmed.
