The doctors of Grey Sloan Memorial Hospital navigated a season of explosive confrontations, heartbreaking goodbyes, and fresh starts in Season 21. With the season concluding in May 2025, here is a complete recap of the major storylines, from Meredith Grey’s power struggles to a finale that left lives hanging in the balance.

Meredith Grey’s Research and a Secret Deal

The season began with Meredith Grey and Catherine Fox in a fierce battle over the direction and funding of Meredith’s Alzheimer’s research. Their conflict reached a tipping point just as Catherine’s health took a serious turn, with her cancer worsening and causing her to collapse. Meredith found herself in a difficult position: she could expose Catherine’s declining health or use it as leverage.

Meredith made a deal to keep Catherine’s condition a secret from her husband, Richard, and son, Jackson. In return, Catherine agreed to give Meredith full control of her research and reinstated the jobs of Owen, Teddy, and Amelia. Meanwhile, Miranda Bailey was also fired but was later rehired as the director of the residency program.

A Rollercoaster of Relationships

The personal lives of the doctors were as dramatic as their professional ones. The relationship between interns Lucas Adams and Simone Griffith was tested by career rivalry and a terrifying armed robbery at a convenience store where they were with Jo. Though they survived the traumatic event and confessed their love for each other, their different outlooks eventually drove them apart. Lucas, who successfully appealed to have his repeated intern year overturned, dreamed of a future together, while Simone was focused on her career. After a painful breakup, Lucas ended things for good.

Jo Wilson and Atticus “Link” Lincoln had a happier journey, deciding to turn their long-term friendship into something more. While pregnant with twins, Jo accepted Link’s proposal. Their wedding in Episode 17 was a chaotic but heartfelt event, featuring an overbearing mother-in-law, a toddler cake thief, and Levi Schmitt walking Jo down the aisle.

Teddy Altman and Owen Hunt attempted an unconventional solution to save their strained marriage: an open relationship. The experiment backfired quickly. Teddy found she couldn’t go through with it, while Owen did, sleeping with an old flame named Nora. After Teddy completed a groundbreaking surgery on Nora, Owen insisted he only wanted Teddy. In a powerful moment of self-discovery, Teddy told him, “I’m choosing me,” signaling the end of their marriage.

Intern Drama and Heartbreaking Exits

The intern class faced immense personal challenges. Mika Yasuda‘s world was shattered when her younger sister, Chloe, was diagnosed with cancer. The stress culminated in a devastating car accident that left Chloe dead and Mika alive but broken. After returning to work, Mika suffered a nervous breakdown and ultimately decided to leave the Grey Sloan surgical program, sharing a tearful goodbye with Jules Millin, with whom she had a complicated romantic relationship.

Levi Schmitt also departed the show. After struggling to find his footing, he accepted a research position in pediatric surgery in Texas. His relationship with the hospital chaplain, James, survived a brief scare when Levi found a mysterious wedding album, and James ultimately decided to move to Texas with him.

Returns and New Dynamics

Ben Warren returned to Grey Sloan as a surgical resident after the conclusion of Station 19. His return was rocky, as he struggled to readjust to hospital protocols and clashed with other residents. His friendship with Jo Wilson was rekindled, providing a nostalgic callback for fans.

Jackson Avery made a brief return to mediate the conflict between his mother and Meredith. In a quick but significant moment for longtime fans, it was revealed that he and April Kepner are back together, sharing a kiss in an elevator.

New professional dynamics also emerged. Jules Millin began working closely with Winston Ndugu, and their mentorship showed signs of developing into a personal connection, creating a potentially complicated situation for the future.

A Cliffhanger Finale

The season ended with a explosive cliffhanger in the episode “How Do I Live.” The interns were celebrating the end of their first year when a desperate mother, Jenna, took Amelia Shepherd, Simone, and Lucas hostage in an operating room. Her daughter, Dylan, was in a coma, and Jenna threatened to blow up the OR with a gas tank if they didn’t perform another surgery.

The situation was defused when Meredith Grey, who had returned to Seattle, helped save Dylan, and Jenna revealed the tank was empty before being arrested. However, in the final moments, Jenna’s husband arrived and revealed that all his gas tanks were, in fact, full. The episode ended with a massive explosion on the OR floor, where Link was still working, leaving his fate and the safety of others completely unknown.
