I think even Casey has got to realize by now her very life might depend on a lone juror buying the reasonable doubt defense.
Now she's got to pull of an Academy Award winning performance & make people believe she's not some monster.... unless she thinks her jury will consist of her own family & anyone they can hire to say they believe her. lol
Casey's life for the most part is over no matter what happens. She is probably the most hated person in America, with her family a close second. Think about it -- she's NEVER going to be able to go out in public without being noticed. Not that she wants a job -- but no business owner is going to hire her and get all of the baggage that comes with it.
If I were Lee, I would sit down and think long and hard if he really wants to go down with the S.S. Casey like his mom and dad are.
