I believe the trash she spoke today was not plan and done on the fly. Yes, I believe it was written, but written quickly today. If you watch the video she is do a lot of pausing while looking down. One instant of that is right after she said TA was alive when she slit his throat.....long pause...then she goes on to say because he was still attacking her.
IMO, she was pissed at what the TA's family had to say about her and also Juan. She could not help herself. The narcissist had to get up and get in her final jabs at the family.
