The following three chapters focus predominantly on Eva. During this period, two years pass. Uncle Tom remains eager for the day when he might reunite with his family, but his hope seems more and more elusive as time passes. As summer arrives, the entire St. Clare household retires to their Louisiana villa. 

Over the years, Tom and Eva have developed an even stronger friendship, and while they sit by the lake, Eva experiences a vision of heaven. She foretells her own premature death, pointing upwards and saying: "I'm going there... to the bright spirits." At some point prior, both Tom and Miss Ophelia observed Eva's decline in health. However, when Miss Ophelia tried to inform St. Clare that his daughter is gravely ill, he disregarded her concerns due to his fear of losing Eva.

While observing Topsy and the other slaves play, Eva questions her mother about the lack of education for the servants. Her mother finds Eva's inquiries strange and states that servants are meant only for manual labor. In response, Eva tells her of her aspirations to establish a school in the North and educate Black people in reading, writing, and religion. Marie dismisses Eva's aspirations with a chuckle.

Alfred, Augustine's twin brother, and his son, Henrique, join the St. Clare group at the summer villa. Henrique, described as a lively and spirited young man with dark, noble eyes, decides to join Eva on a horseback ride. When Dodo, Henrique's servant, brings out the horse, the St. Clare boy scolds him for not brushing it properly. Dodo tries to explain that the horse got dirty again soon after being cleaned, but Henrique becomes angry and hits him. 

Tom intercedes, confirming Dodo's story, and Eva advises Henrique that he frightens Dodo into lying when he treats him harshly. In an attempt to ease his own guilt, Henrique gives Dodo a coin, but Eva speaks kindly to Dodo, treating him as a person. She then makes Henrique promise to treat Dodo more humanely and to love him as a servant.

The St. Clare brothers witness the event, which leads to a conversation about Henrique's personality. Augustine remarks that Henrique is an aristocrat by nature who looks down on other people. Alfred is aware of his son's behavior but still defends him, claiming that only the well-educated and sophisticated should have equal rights, not the "uncivilized masses." Augustine counters by citing the American and French Revolutions, where the idea of freedom and equality originated.

Following Alfred and Henrique's departure, Eva's health deteriorates. It's only when Miss Ophelia brings Eva's situation to Marie's attention that she starts to display some motherly concern for her daughter. Eva then confides in Tom, expressing her willingness to sacrifice her life for the well-being of the servants, who she knows are suffering. She also gets St. Clare to pledge to set Tom free after her death.
