The scene at Lee's childhood home
The scene at Lee's childhood home when Jack takes her back home to her mother's house is such a chilling scene I always shudder when I watch it. Listening to her mother's "good riddance" speech and Lee's comments in the yard afterward, when she tells Jack that she wishes she had fallen from the tree and broken her neck, while her mother watches through the window in the door behind them, and then turns off the lights - it's just such a creepy, lonesome moment, filled with utter rejection.
In contrast, the scenes at Jack' house are warm and welcoming and filled with love, forgiveness and acceptance. It's easy to see how Lee is awed by the family and fell in love with them. I think that was one of the reasons why she's willing to face a prison sentence because she knows what's waiting for her when she's released.
I also like to think that Jack is able to work out a deal where she's given a reduced sentence and perhaps even a pardon.
