Elizabeth returns to her job at County General soon after the start of season 9, where she becomes harsh with patients, curt with colleagues, and particularly clashes with Med Student Paul Nathan (Don Cheadle) who is trying to become a physician despite advancing Parkinson's disease. Elizabeth later confronts her agony over Mark's death and also makes peace with Nathan during a horrifying case where the wife and son of a decent man have been killed by a drunk driver, and they are able to save his other son by doing a transplant from the dying son. Corday is saddened to see Romano losing his career due to his arm amputation/reattachment. An even bigger blow hits Corday later during Season 10 when Robert Romano is killed in a helicopter accident. Later in the season, Dr. Corday is appointed to Chief of Surgery by Kerry Weaver.
