The Pitt Season 3: Who’s leaving and who’s returning for the next shift

Noah Wyle's Dr. Michael "Robby" Robinavitch is the central character in The Pitt. He serves as the Chief of Emergency Medicine at Pittsburgh Trauma Medical Center. Known for his wry sense of humor, sharp sardonic attitude, and spunk, Dr. Robby has earned the respect and admiration of the staff at the Center. Much of Season 3's focus will be on his healing as he battles trauma after hitting a breaking point in Season 1.

Ganesh's Dr. Samira Mohan is one of the major characters not returning for the third season. Per reports, the move to write out the character comes as a story-driven decision, and focuses on the reality of how residents move on from training hospitals. The senior resident at the center will be sorely missed after becoming a fan-favorite in the two seasons. Ganesh departs the show after two seasons.

No nonsense, and a personality who commands attention and respect, Katherine LaNasa's Nurse Dana Evans is the backbone of the ER. In the two seasons so far, LaNasa has established herself as a fan-favorite, as she balances life in the ER and outside of it. Despite her relationship that toggles between heartwarming and extreme, she also serves as an anchor for Dr. Robby as they run the ER together.

Patrick Ball's Dr. Frank Langdon is the senior emergency medicine resident and is also Dr. Robby's protege and a hospital favorite. Known for being competent, Ball's character has experienced a solid development arc in the first two seasons.

Ifeachor's character, Dr. Heather Collins, was introduced as a fourth-year resident in The Pitt's first season. The exit after Season 1 comes as a narrative-driven move despite rumors of a personal choice to leave the drama. With the setting of a teaching hospital, Ifeachor's exit adds to the realism of how the system works.

Dourif's Dr. Cassie McKay is a resident physician at the ER, and comes in with a persona shaped by addiction, recovery, and motherhood. Regarded as stable and reliable, there are scenarios that see her act on impulse. As of the second season, she's been clean of her addiction for nine years, setting up an interesting character development in Season 3.

Also returning is Dearden as Dr. Melissa King, a second-year and later third-year resident with an autistic twin sister. She works under Dr. Robby's supervision and is known for bringing her unique perspective to emergency cases at the center. The second season focused on her personal life and how taking care of her sister has come at a cost for the talented resident.
