How does Hager support her beliefs regarding slavery?

Hager tells the story of her plantation and her life growing up there. She grew up playing with the mistress's daughter and they were good friends. When she grew up, the plantation owner, Mr. Jeanne, left for the Civil War and died. Miss Jeanne was devastated. When the slaves were freed, everyone left but Miss Jeanne and Hager, and Hager took care of her until she walked off her balcony thinking her husband had come home. Towards the end of the chapter, Hager tells Sandy that she stayed because she loved Miss Jeanne and wanted to help her.
