The house where Jean Louise
grew up (in her flashbacks and the events of To Kill a Mockingbird
) has been torn down by the time of the events of Go Set a Watchman
, and replaced by an ice cream shop. This shop is run by Mr. Cunningham (from one of the poorest families in Maycomb). The ice cream shop in the place of her old house represents the disillusionment Jean Louise experiences when she comes home—the sense that everything has changed and she doesn’t belong in Maycomb anymore. The ice cream shop is the first place she goes after seeing Atticus
at the citizens’ council meeting, and so it is immediately connected to the disillusionment she experiences at the courthouse. After feeling like her father and oldest friend have been irreparably changed, Jean Louise then sees her childhood home replaced by an ice cream shop and a field of gravel.
