Nancy (The Green Death)

Nancy was a member of Professor Jones's Wholeweal community in Llanfairfach, Wales.

She was the caregiver and the cook for the group. She was also a qualified medical nurse capable of preparing and administering an intravenous injection. When Professor Jones was infected by the green slime, she helped Jo look after him until they found a cure.

The group called her "Nancy with the laughing face." (TV: The Green Death)
