The prosecutor has got his work cut out for him with SK. Lying and drawing people into her fantasy world is her life's career. I hope he is being aided by a psychologist because I think SK could very easily turn the tables on him and make him appear to be victimizing her, so she gets the jury's sympathy. It'll be a piece of cake for her. He will need to employ a lot of skill.
That's why it has been so important to get the testimony of all her former partners, and fortunately they have the 8 hours of tapes too. It's very unusual to have bad character testimony but in this case it was absolutely essential. It will be a case of getting the jury to see how she manipulates, without the prosecutor looking like the bad guy.
