Juliet writes to Dawsey and mentions that she's received two letters from Miss Adelaide Addison and others from Isola and Clovis. Because of those letters, her article is coming along well. Juliet shifts topics and says she'd like to more about children. She explains that she's a godmother to a three-year-old named Dominic, and is always shocked by how fast he grows. She explains what a mongoose looks like.
When Juliet explains what a mongoose looks like, she indirectly begins to care for Kit as well as Dominic by nurturing her curiosity and teaching her about the world. In this way, she's able to begin the process of integrating herself into Kit and Dawsey's lives.
