It’s been three years since Alex Karev (Justin Chambers) left Grey’s Anatomy in the middle of season 16, and while Grey’s Anatomy season 20 could provide the opportunity for his character to return, it would be a bad decision. As one of the original five Grey’s Anatomy interns from season 1, Alex was an integral part of the series from his introduction through his exit when he and Meredith were the only two still left standing. Through his character growth and development from the cocky, misogynistic intern to the caring, kind, protective pediatric surgeon, Alex became a Grey’s Anatomy fan favorite, but his character is better left in the past.
Grey’s Anatomy season 19 was a season of endings and new beginnings, with Meredith and Maggie both leaving the series as main characters and Addison and Jackson making important returns. This leaves the door open for Grey’s Anatomy season 20 to follow suit by bringing back characters who had open-door exits, like Alex Karev. However, unlike Addison, who received her own spinoff show, and Jackson, who got his long-awaited happy ending with April, Alex’s exit was controversial and poorly received. In Grey’s Anatomy season 16, Alex left Seattle and his wife Jo to be with Izzie and the twins she’d had through frozen embryos.
