This Is Us Season 5 Episode 6 focuses on Randall's family history as he and Beth visit Hai, who tells him the story of Laurel's life.

When Randall and Beth first arrive at the farmhouse, Hai tells them that the land is theirs. It belonged to Laurel. He begins by explaining that Laurel was a Dubois, a rich and influential family in New Orleans. We see that as a child/teenager, Laurel was close with her Aunt Mae, who her father forbade her from seeing.

When Laurel is a young woman, her brother Jackson was killed in Vietnam. Aunt Mae comforts her and encourages her to go into the lake to scream out her pain. Hai is on a fishing boat -- he is a refugee from Vietnam who barely speaks English -- and hears her scream, so he tries to save her.

Later, Laurel meets Hai at the farmer's market where Aunt Mae works. They begin a secret relationship while Laurel is betrothed to some boring banker her father picked out. She runs away rather than marry Marshall, but Hai can't come with her.

Randall is impatient to cut to the chase. Why didn't Laurel seek him out? Hai explains that Laurel was arrested for drug possession and spent five years in prison. When she got out, she was clean for the rest of her life but too ashamed to seek Randall out.
