Six-Thirty disliked walking past the location where Calvin died whenever he visited the cemetery.
While at the cemetery, Six-Thirty carefully avoided the groundskeeper and placed daffodils on Calvin's tombstone, which had a partially-engraved quote from Marcus Aurelius.
The chapter reflects on a past conversation where Elizabeth questioned the limits of language comprehension in dogs.
Elizabeth and Six-Thirty embarked on a "word quest" with Elizabeth teaching him using children's books.
Six-Thirty was wary of the groundskeeper who carried a rifle and communicated with both the deceased Calvin and the unborn child in Elizabeth’s belly.
About three months after Calvin's death, Elizabeth, in a nightgown and galoshes, started demolishing the kitchen with a sledgehammer to build a lab.
Despite being pregnant and grieving, Elizabeth demonstrated immense capabilities and faced condescension at the lumberyard when gathering materials for her lab.
Elizabeth charged colleagues from her former workplace for professional advice, creating a no-nonsense pricing strategy for personal or insensitive comments.
The kitchen was transformed into a laboratory over four months with equipment and safety installations, requiring assistance and learning from Six-Thirty.
Six-Thirty communicated concerns to Calvin about Elizabeth's unrelenting work, her staring spells, and the impact on the unborn child, as well as the continued but futile word lessons.
The groundskeeper aimed his rifle at Six-Thirty, but the dog disarmed him, preventing another tragedy and ultimately saving the man's life.
A reporter who covered the scene recognized Six-Thirty and drove the blood-covered but unharmed dog back home, presenting him as a hero in the news.
An article was published about Six-Thirty's heroic act, lifting the cemetery dog ban and prompting plans to replace both the groundskeeper and Calvin's damaged grave marker.
Elizabeth reads the newspaper article and connects a newly broken portion of Calvin's tombstone inscription, "Your days are nu," with a meaningful memory shared with Calvin.
