Helen Singer

Helen Singer was the mother of Kyle Singer and the wife of Sam Singer. She was sick, which was why Kyle snuck the coke into the country. Helen was concerned when Kyle paid the rent and discussed it with Sam later. When Sam found out Kyle was smuggling drugs, he tried to stop him, but he tore the bag open instead. CTU thought this released the virus, but luckily it was part of a sting operation by Jack Bauer, Gael Ortega, and Tony Almeida.
