Sophie's alias for this job is "Stella Havisham." This is likely a combination of Stella Kowalski, from Tennessee Williams' "A Streetcar Named Desire" (which was set in New Orleans), and Estella Havisham, a character from Charles Dickens' "Great Expectations" who lives in an (arguably) haunted mansion.
Sophie's fictional deceased father "Big Daddy" was named after the character Big Daddy in Tennessee Williams's Cat on a Hot Tin Roof
When Parker confesses to Tina that she used to believe in psychics, but that Sophie and the others showed her the truth, she's referring to the events of The Future Job (2010).
