When Jessica came to see Tiana, she was angry but when she left, she was furious, she desperately wanted to rub the smug smile that Tiana had the entire time, she wasn’t even fazed by her threats at all…she was going to kill that brat no matter what, she is not going to tell her daughter about the change in plans, she is going to plan such a perfect murder that no one would suspect her or her daughter.. Tiana watched as Jessica left and she knew she had succeeded, and everything was going according to plan, she is the one that made sure that the information about Rose and Andrew’s divorce reached Jessica and Julian... she knew that Rose would tell her mother the truth and that Jessica would likely threaten her, so all she had to do was to give Jessica another reason to be angry at her...
