The community of Sweet Home seems to continue to live on in Sethe, especially because of the rememory. The concept of a rememory is stronger than a regular memory because a rememory seems almost to have the power of a hallucination; it's like a place or person can suddenly spring up before one's very eyes and the rememberer is powerless against it. For example, when Sethe goes to wash the chamomile sap off her legs, she hears the water splash and sees her shoes and stockings laying on the ground, and
suddenly there was Sweet Home rolling, rolling, rolling out before her eyes, and although there was not a leaf on that farm that did not make her want to scream, it rolled itself out before her in shameless beauty. It never looked as terrible as it was and it made her wonder if hell was a pretty place too. Fire and brimstone all right, but hidden in lacy groves. Boys hanging from the most beautiful sycamores in the world. It shamed her—remembering the wonderful soughing trees rather than the boys. Try as she might to make it otherwise, the sycamores beat out the children every time and she could not forgive her memory for that
The place where she met and "married" Halle, the place where Mrs. Garner was kind to her, where she had her first three children, where she was assaulted by schoolteacher's nephews, where she had to abandon Halle, where schoolteacher compared her to an animal, the whole of the place comes rushing back to her because it seems to live on within her. She can never forget.
Further, the first time the reader sees Paul D, he is referred to as "the last of the Sweet Home men." When he speaks to Sethe, he "treat[s] her to a mild brotherly flirtation" just like "All of the Sweet Home men" did both before and after Sethe married Halle. Denver's response to Paul D when she comes into the kitchen makes clear just how much Sweet Home and the Sweet Home men live on in Sethe and Paul D:
They were a twosome, saying "Your daddy" and "Sweet Home" in a way that made it clear both belonged to them and not to her. That her own father's absence was not hers [....]. Only those who knew him ("knew him well") could claim his absence for themselves. Just as only those who lived in Sweet Home could remember it, whisper it and glance sideways at one another while they did.
Moreover, Paul D also carries the chain gang with whom he served his prison term in Alfred, Georgia, with him too. Although he is no longer a prisoner or a slave,
It was some time before he could put Alfred, Georgia, Sixo, schoolteacher, Halle, his brothers, Sethe, Mister, the taste of iron, the sight of butter, the smell of hickory, notebook paper, one by one, into the tobacco tin lodged in his chest.
His memories of their awful, degrading lives, as well as their miraculous escape from the boxes below ground in which they were made to sleep, continue to shake him. He was a "Buffalo man" just like each of them, and that horrible place remains alive in him too.
