It’s currently unknown whether or not Grey’s Anatomy will be renewed for a Season 18 as showrunner Krista Vernoff is preparing the finale as not only a season finale but a series finale, just in case.
The news of Robert I. Mesa’s promotion comes just weeks after major character Dr. Andrew DeLuca, played by Giacomo Gianniotti, was killed off in the spring premiere.
The series is down to just a few remaining characters from the first season, but the ever-changing cast list for Grey’s Anatomy is not uncommon for a show that has been going on for nearly two decades.
