Eventually they make their way to a plantation where her great grandfather once lived, and where an old woman now resides. The old woman tells them to go away. But Grandpa Walton - of her generation - persuades her to let Verdie look at some records in the house. Eventually Verdie and Jason find sketches of everyone that lived on the plantation including the slaves, one of them being Verdie's great-grandfather who came from Africa.
The way this whole sequence is filmed really makes you feel you're right there along with Verdie, Grandpa, and Jason. When they go into the attic, you get the feeling that no one has been there in years, and that they'll probably be the last people ever up there, until the old woman dies.
At the end of the episode, there's a close up of Verdie praying that one day someone in her family's line will have an opportunity to travel to Africa and discover deeper roots.
I wished the episode ended on that note, but there was the obligatory ending where everyone in the Walton house says "Goodnight" and I thought that sort of killed the mood. Otherwise, it's a great episode.
