In May, executive producer Bill Lawrence revealed that he was looking to stunt cast the role of Dr. Kelso's successor. This news comes as yet another continuity dilemma, after Kelso made an appearance as the Chief of Medicine in the season finale, when he had previously retired and replaced by John C. McGinley's character Dr. Cox.
Cox's boss lady character will "ruffle feathers," said a Scrubs insider.
This role comes as a relief after her appearance in Dirt. Now Cox has a job doing something she does better - making people laugh.
