where did the mother go in the waltons
The Waltons John-Boy's military plane is shot down, while Olivia becomes a volunteer at the VA hospital and is seen less and less; she eventually develops tuberculosis and enters an Arizona sanitarium. Olivia's cousin, Rose Burton, moves into the Walton house to look after the brood. Two years later, John Sr. moves to Arizona to be near Olivia. Grandma appears in only a handful of episodes during the eighth season (she was usually said to be visiting relatives in nearby Buckingham County).
