I think we all really know why the narcissist doesn't want to testify with anyone there but the jury.
She knows her lies will be torn to shreds and dissected like a bug by the court trial watchers and the media.
She is beyond vain. She thinks if its only the jury she can make up another story and add to her already monumental lies.
I don't think anyone is fooled by JAs game.
IMO
She will never eat humble pie in front of the Alexanders. She'd rather go to death row.
