Viola begins to read the diary in a "Prentisstown accent." (We'd totally like to hear that, by the way.) Todd's mom is writing the book to Baby Todd, and she tells him that they live in a wonderful New World, even though it's a difficult life.
She tells him about the Noise and the Mayor Prentiss, who convinced Mayor Elizabeth that the town should be built far away from the rest (red flag).
She tells him about Aaron, and sounds a bit suspicious about his preaching; she also tells Todd about the Spackle, whom she believes are gentle and intelligent creatures (even though many people in Prentisstown think they're animals).
As Viola reads on, it seems like Todd's mom is putting a rosy tint on some dark feelings, but she stops herself from saying anything outright.
She tells Todd that she sees all of the good and pushes through because she loves him.
She also writes out the lyrics to a song—the song that Ben used to sing. Viola sings it out loud, and it gives Todd goose bumps.
Todd's mom tells her that the song is meant to show him that his mother will always be there for him.
Viola stops there and his mother's promise rings in his ears. He watches Viola, mesmerized.
He knows what she's thinking: She's been reading the diary, pretending it was her own parents, telling her they love her.
Todd feels so confident that he understands Viola, and the she gets him.
He says her name and reaches her hand up toward her, and all she says back is "I know."
