Chicago Med: Every Second Counts in the Heart of the ER

Though her return was a surprise, Rachel Dipillo’s Sarah Reese had a good reason for leaving Chicago Med at the beginning of season 4 and returning in season 10. Reese was originally a medical intern who had a difficult time finding her footing. She almost quit medicine after deciding Pathology was not for her, but Dr. Charles (Oliver Platt) convinced her to work for him instead. Thus, Reese was part of the original cast of the One Chicago universe’s medical drama, though she disappeared for six years after her exit.

Reese parted with Gaffney Medical Center on poor terms with Dr. Charles after she felt betrayed by him and supposedly went to Texas. However, when she returned in season 10, she revealed she had been working in Chicago for the past four years and was now working at a psychiatric clinic nearby. Thus, she could become a recurring part of the Chicago Med season 10 cast who is occasionally a thorn in Charles’ side.

Dr. Sarah Reese Decided To Leave Gaffney In Chicago Med Season 4

Reese Felt Betrayed By Charles After Her Father’s Death

Reese left Chicago Med after the season 4 premiere because she felt that Dr. Charles had betrayed her. This decision came after the climax of a long arc in which Reese struggled with whether to allow her father, who had abandoned her as a child, to come back into her life, something she considered seriously despite brain scans proving he was a psychopath. Reese’s father died of a heart attack after Dr. Charles confronted him with proof that he had killed two girls in Wisconsin, and, unfortunately, Reese believed Charles didn’t try hard enough to save him.Reese’s exit was disappointing on multiple levels. The story had been set up for her to grapple with her father’s guilt in several murders, but that aspect of the story vanished along with his death, especially because Reese left right afterward. Additionally, it was heartbreaking that she blamed her mentor for her father’s death and didn’t resolve the issue before she left, especially considering that Charles stopped her from quitting medicine and helped her discover her passion for psychiatry.
