The episode where Nellie Oleson has her twins is one of many favourites for fans of Nellie Oleson because it showed Nellie in quite a different light as she is experiencing motherhood for the first time, which continued with the changes everyone saw when she met and married Percival Dalton.
The episode is titled Come, Let Us Reason Together, with the title coming from the momentous decision between Nellie and her husband Percival about what religion to raise their children. Percival was raised Jewish while Nellie was raised Christian, and they are both wanting their children to be raised in their own religion. Percival’s parents arriving in Walnut Grove, and also insisting that their children be raised Jewish was also an issue for the couple.
At the end of the episode, Nellie and Percival end up having twins, one girl and one boy. So as a compromise, where the title comes from, they decide to raise their son Jewish and their daughter as Christian.
