Nancy Turner is Heidi Turner's mother, as Heidi has been seen with three sets of parents. She was first shown in "Marjorine", at Heidi's slumber party. Heidi's other mothers, seen in "Probably" and "Two Days Before the Day After Tomorrow", were likely the result of her character model not being finalized, as she is normally a background character. Her name was revealed in South Park: The Stick of Truth, during the quests to recruit the girls.
