The Real Reason
Rachel DiPillo
Left Chicago Med
Cast members have departed from the "One Chicago" franchise shows for a variety of reasons; some personal, some professional, some because of the writers' decisions. In the case of Rachel DiPillo, who played Chicago Med's Sarah Reese for three seasons and in the beginning of the fourth, the details are a little more nebulous.
When Sarah Reese's long-absent father returns to her life as one of Dr. Daniel Charles’ patients, things take a turn for the worse when her father is diagnosed as a psychopath, revealed to be a serial killer, and ultimately has a heart attack. Reese ends up leaving Gaffney Chicago Medical Center for good, striking out for a life far away in Texas.
In an interview with Fansided, showrunners Diane Frolov and Andrew Schneider spoke briefly about Rachel DiPillo's departure, saying, "If we can find a good way to bring her back later, we'll entertain that." However, it's completely unknown if DiPillo even wants to come back to the show, as details about her personal life suggest she's no longer acting.
DiPillo hasn't taken up a single new role since her final episode of "Chicago Med." Since her Hollywood departure, it's unclear what she's been up to, and though her Twitter has seen some rare activity recently, it has nothing to do with acting or another profession. This may suggest that it was DiPillo's decision to leave the show, but we may never know for sure.
