Tom rents a classic convertible car and meets Ally for lunch, where they get to know each other a little better. Bea and Pete arrive to share Tom's last two weeks in America. Tom has done some more genealogical research and discovers that his and Bea's great-great-grandmother, Rebecca, may have been a Native American Indian. He, Pete, Bea, and Monk drive to an Indian reservation to trace his Native-American past, and meet Running Bull, a chief, and White Feather, an elderly shaman. Their inquiries lead them to a local store, where the owner, Marty, reveals the surprising truth about Tom's great-great-grandmother. And a phone call from Mr. Pfister in London, who has Tom's DNA results, tells him even more about his roots.
