It is later revealed that the day she left Chicago, Carol sent for her twin daughters to join her and Doug in Seattle. Eight years later in the Season 14 episode, "Status Quo", Jeanie Boulet mentions Doug and Carol when she returns to the ER after her ex-husband's death and learns of brain lesions due to AIDS progression in her son. Nurse Haleh Adams states that they are living happily in Seattle and that their twin daughters are now in third grade. In the season 15 episode "The Book of Abby", long-serving nurse Haleh Adams shows the departing Abby Lockhart a closet wall where all the past doctors and employees have put their locker name tags. Amongst them, the tag "Hathaway" can be seen. Carol Hathaway appears again in Season 15. She and Doug are now married and practice at the University of Washington Medical Center, where Carol is a transplant coordinator. During the episode, Carol and Doug help a grieving grandmother (Susan Sarandon) donate her grandson's organs. One of the organs, a kidney, is given to "some doctor"; unbeknownst to both Doug and Carol it is their former co-worker and friend John Carter. While on the job she met two current employees at Chicago County General Hospital Dr. Neela Rasgotra and Nurse Manager Sam Taggart. Hathaway was originally supposed to die in the pilot episode of ER, but the character tested so well she was kept on. "Entertainment Weekly" placed Hathaway in its list of the "30 Great TV Doctors and Nurses". Her relationship with Doug Ross was included in AOL TV's list of the "Best TV Couples of All Time" and in the same list by "TV Guide".
