As Chicago Med gears up for its tenth season, the series will undergo substantial changes, beginning with a major shift in its cast. Dominic Rains, a central figure since season 5, will no longer be a regular on the show. This development comes in the wake of season 9’s climactic finale, which suggested an imminent exit for his character, Dr. Crockett Marcel.
Rains joined the “One Chicago” universe as a main trauma surgeon, stepping in after Colin Donnell’s Dr. Rhodes exited the show. Over his tenure, Rains’ character became integral, not only to Chicago Med but also made impactful appearances across the franchise’s other series. His departure represents a significant change in the show’s dynamics, especially as it comes amid broader changes behind the scenes. Season 10 will proceed under the guidance of Allen MacDonald, who takes the reins following the exit of co-showrunners Diane Frolov and Andy Schneider.
