As the March household faces the departure of Mrs. March (Marmy) to tend to their wounded father in Washington, the sisters are left with a guiding mantra: "hope and keep busy." This simple directive becomes the emotional anchor for Meg, Jo, Amy, and Beth. The text highlights how the girls find "relief in their routine," treating their daily tasks as a necessary distraction from the anxiety surrounding their father’s health. The "fat letters" exchanged between the Washington hospital and their home serve as a "wonderful lifeline," providing tangible proof of their father’s recovery and sustaining their morale during this period of separation.
Despite the collective effort to maintain normalcy, the underlying theme of sacrifice remains prevalent. Mrs. March had specifically instructed the girls to "look after the unfortunate family"—the Hummels—during her absence. While Meg and Jo become preoccupied with their own exhaustion and professional duties, Beth, despite feeling unwell, takes it upon herself to fulfill this compassionate obligation. Her decision to visit the Hummels, even when her head "aches" and she feels "very tired," underscores her selfless nature. This act of service, however, leads to a devastating consequence: the death of the Hummel's baby in her lap and her subsequent exposure to scarlet fever.
Upon returning home, Beth’s condition reveals the gravity of the situation. Jo, upon finding her sister with "red eyes" and in tears, realizes the danger. When Beth asks, "You've had scarlet fever, haven't you?" the reality of the contagion sets in. Jo’s reaction—exclaiming "Christopher Columbus" and feeling immediate terror—reflects the severity of the illness. The narrative emphasizes the guilt Jo feels, stating, "If you get sick, I'll never forgive myself." This moment marks a shift in the family dynamic, moving from the hopeful anticipation of their father's return to the immediate, visceral fear of losing another family member.
To manage the crisis, the family is forced to reorganize. Dr. Banks confirms that Beth has "symptoms of the fever," necessitating a quarantine of sorts. Amy, who has never had the illness, is sent to live with Aunt March to ensure her safety. The emotional toll on Amy is significant; she initially struggles, feeling she "can't bear it," but finds a sliver of solace through the playful intervention of Lori. Meanwhile, Jo assumes the role of primary caregiver, committing to "nurse Beth" through her illness.
Ultimately, this chapter depicts the fragility of the March family's newfound independence. The transition from the comforting routine of "hope and keep busy" to the stark reality of scarlet fever forces each sister to confront their limitations. The narrative poignantly captures the intersection of duty and danger, illustrating how the very kindness that defines the March sisters—their commitment to the Hummels—becomes the source of their greatest trial.
