When Ceanne and Rashelle speak to their mother for the first time in two months on Dr. Phil’s stage and confront her with her alleged behavior, she continues to deny “abuse.”

In the video above, Dr. Phil doesn’t mince words when he confronts Jemma about her behavior. “There is absolutely zero doubt in my mind that you have been abusive with these girls throughout their life,” he says. “You have confessed to everything they have accused you of.

But you have been and you need to acknowledge that with no buts, no conditions and no qualifications … They have never heard you say, ‘I crossed the line and abused you girls, and I am sorry and will spend the rest of my life making it up to you.’”
