May-December.....September. Doctor's Lady S1 Ep 17

Is there a Doc in the house? Because Harriet Oleson’s niece, Katy Thorvald, comes for a visit to Walnut Grove and needs some attention. Which leads to her being immediately smitten with the small town Doctor. The two quickly become a pair, having picnics, sharing carriage rides and visiting patients together. However, as their love blooms it also sprouts skepticisms from some residents and even Doc Baker himself. Will Doc Baker really end up rocking the cradle of love?
