In the first episode of a two-part story, Almanzo (
Dean Butler) asks Charles' permission to marry Laura (
Melissa Gilbert), but Charles insists that she cannot wed until she is 18 -- two years from now. Upset that Laura concedes to her father's wishes, Almanzo leaves town. Meanwhile, Mrs. Oleson (Katherine MacGregor) hires a new restaurant worker named Percival Dalton (
Steve Tracy) -- who promptly falls in love with Mrs. Oleson's daughter, Nellie (Alison Arngrim). And outside of Walnut Grove, Adam Kendall (Linwood Boomer), the husband of Laura's sister Mary (
Melissa Sue Anderson), receives some discouraging news. ~ Hal Erickson, All Movie Guide
