Moody tells Ben that she's angry. She knows she should be grateful for the trial and the work he and Jonah did—she even gets what her grandpa means when he points out that change takes a long time to happen—but she's ticked off that it's not happening fast enough. She doesn't want to be old by the time things change in her life.
Moody needs some wintergreen oil for Abraham, but she can't go into town and get any since she's Black, so she asks Ben to go for her.
He agrees but on one condition: she goes with him.
