Overview and Answer
Dr. Alex Karev, portrayed by Jesse Spencer, exited Grey’s Anatomy in the Season 16 finale titled ‘Leave a Light On,’ which aired on 5 March 2020. The departure was not abrupt; it capped a multi-episode arc that addressed Karev’s struggle with burnout, his relationship with Alex, and an offer to lead a surgical program in Oregon. While the on-screen exit occurs in Season 16, the emotional and narrative consequences extended into Season 17 and beyond, reshaping the dynamics of the Meredith-centric storylines.
Context: Karev’s Arc Before the Exit
