Does anyone see this as setup? Stiviano was being sued by the estranged wife. Whether she is an assistant, she is working more like an escort. I am not suggesting sexual activity. As a friend of escorts, some have rich elderly clients that seek and pay for help in different ways, and the Sterling/Stiviano relationship mirrors this type of courtesan-ship. These types of relationships have unspoken rules.
So now, the courtesan is sued by the estranged wife. The client is unable to stop and violates and unspoken rule of causing hardship because of the relationship. The courtesan, with short term wealth, cannot fight a lawsuit that takes time. This outing is the payback for the lawsuit. Stiviano tapes the conversion with the intent to draw out comments to make life miserable for the old man.
