In chapter 12 calpurnia’s identity is shown massively because she is told by Scout that she has a ‘double life’, meaning she is unsure of her identity. This happens when Calpurnia sends Jem and Scout to a black church and they seem to find that Calpurnia is acting differeny towards them, instead of her normal. Moreover, Jem and Scout find out a shocking mystery, that Calpurnia has a child who barely knows him. She also barely acknowledeges her birthday, which makes us believe that Scout is right and Calpurnia is living a double life. We start to feel alot of sympathy for Calpurnia because she has put her social life beside and focused more on being a housewife for the finches.
