Constantine's daughter Rachel

Apparently, the filmmakers weren't comfortable with trying to pull off what happened in the book. This weak alternative was the result.

In the book, Rachel is 'high yellow.' She can pass for white. She comes in while the Daughters are mingling and chats with them, infuriating them when they find out she's actually a negro.

Rachel had left the southern way of life for a long time. Black people in the north experienced racism but they still had the right to vote and be full citizens. Black people in the south did not have those rights. Her mother acted submissive because that was the racial code while this type of "submissive behavior" made zero sense to Rachel who was living the city life in the north.

So she "sass mouthed" (as they say in the film) her Mother's employer causing her Mother to lose a job.
