There is one scene in the video where Sarah, Duchess of York, realizes what she has done, but she is unable to extricate herself, and change her mind. It is the scene where she has the $40,000 in front of her, and she buries her face in her hands, and it appears she is emotional. This is not a happy emotion. This is the recognition that she has done something wrong, but she cannot turn back now because the stakes are too high. If Sarah had a true spine, she would have handed that money back, and said, no, this is wrong. I cannot do this to my former husband.
But she cannot see through her tears. She cannot see that accepting the money will only hurt Prince Andrew, and endanger her relationship with him, and with their two adult daughters.
It was at this moment when Sarah crossed the Rubicon. She has no one to blame but herself.
