Although many of Dani's tactics were immoral, she is the only one who stuck to her game plan. She may not be leaving with $500,000, but she has manged to secure $50,000...which is more than she started with.
I hope Dani's husband restricted their children form watching the show!
Dani ought to be ashamed when she gets home because everyone she knows will know how she acted in that house, and people may find it very difficult to trust her from now on.
