Kate from season five: "You Know I Can't Hear You When The Thunder Is Clapping", where Betty Jo reveals to Kate that Steve and she are in love; "A Cottage For Two", where Betty Jo's dream house turns out to be an old shack; and "With This Gown I Thee Wed", where Steve and Betty Jo get married. The episode aired just 13 days after Benaderet's death on October 13, 1968.

Previously, Lockhart had played another mother figure - Ruth Martin on the popular CBS-TV series Lassie. Lockhart's character was essentially brought on as
