Going back to Mabel/Cora: When she's having the fantasy in NC about going North:
In another scene, years hence, Cora walked down a busy street in her city and came across her mother. Begging in the gutter, a broken old woman bent into the sum of her mistakes. Mabel looked up but did not recognize her daughter. Cora kicked her beggar’s cup, the few coins flew into the hubbub, and she continued on her afternoon errand to fetch flour for her son’s birthday cake.
Not even a slave anymore and still carrying that water.
