Following Tico's death, Jessica begins to suffer from blackouts and losses of time. It is soon revealed that, like her mother, Jessica suffers from dissociative identity disorder. Jessica is once again romantically involved with Antonio in 2005, but her wild alter ego, Tess, parties and meets other men. Antonio is engaged in a custody battle with R.J. over Jamie, and the stability of his relationship with Jessica is an important factor; Jessica discovers her condition, and soon realizes that she is a danger to not only the case, but Jamie's safety and well-being. She quietly checks herself into St. Ann's sanitarium to get treatment to integrate her personalities, but soon Tess emerges and plots to escape. Fellow patient Addie Cramer shows Tess some of her treasured belongings, including the report card of her granddaughter Starr Manning — the daughter of Jessica's uncle Todd and Addie's daughter Blair. Tess uses Todd's signature from the card to get herself released, but Todd, already suspicious of Jessica's behavior, figures out that Jessica is under the influence of an alternate personality and drags her to Llanfair to tell Viki. Not wanting to be integrated out of existence, Tess incites a huge argument with Todd that causes Viki to have a heart attack. She survives, but Tess escapes to New York City.
