Erin (Mary McDonough) wants to marry Ashley Longworth Jr. (Jonathan Frakes), but there is a major roadblock to their future happiness: unlike the deeply religious Waltons, Ashley is an atheist. His explanation that the War has soured him on the concept of God meets with shock and disappointment from Erin's family -- with the exception of her father John (Ralph Waite), who understands Ashley's spiritual crisis even if he doesn't condone it. Meanwhile, Elizabeth (Kami Cotler) is getting sick and tired of her "tag-along" cousin Serena (Martha Nix).
