However, Katie's body began rejecting the heart not long after; her prognosis looked rather grim. She began taking anti-rejection medicine; but despite that, she realized that death for her would be inevitable. Her family helped to set up a lovely prom night for her, (her dress was a Forrester Original which had been brought over by Eric's friend, and Nick's mother, Jackie) wherein Nick and Katie had a nice time. Stephanie also sat up with Katie, helping her through her situation, because she had always gotten on well with her. Despite all the best medical help, Katie's condition continued to deteriorate. Until Katie's niece, Bridget, discovered a cool gene therapy, which had been done in Stockholm that could perhaps help. With the aide of her doctor, Bridget put the therapy to work, and was pleased that it was successful. The therapy broke her fever, and although it still meant Katie had to take her anti-rejection medication, the crisis had seemed to pass.
