Like “Orange Is the New Black,” the series in the One Chicago universe that are still on the air — “Chicago Med,” “Chicago Fire,” and “Chicago P.D.” — are extremely popular (via Showbiz Cheat Sheet). They are consistently raking in high ratings, and all three of the series are beloved by large groups of fans. While “Chicago Fire” is the most popular, “Chicago Med” is close behind in views and ratings.
Harney appeared on an episode of “Chicago Med” during the show’s inaugural season (via IMDb). Furthermore, he portrayed Dr. Ron Unger in the 2016 episode “Intervention.” The episode centered around Colin Donnell’s Dr. Connor Rhodes and Bryan Tee’s Dr. Ethan Choi’s disagreement over a dying patient’s request. The doctors were also tasked with having to save a patient dealing with flesh-eating bacteria. Harney’s character was on the scene during a code blue fiasco in which the doctors were unable to save the patient.
The episode dealt with a lot of loss and traumatic illnesses, but the team worked together the best they could — and Harney ultimately did really well as Dr. Unger. Who knows? Maybe he’ll reprise this role at some point.
