'Grey’s Anatomy' closed out its 22nd season on May 7, with a dramatic finale that delivered a bridge collapse, a surprise proposal, and the departure of two longtime fan favorites. The episode, titled 'Bridge Over Troubled Water,' saw Dr. Owen Hunt and Dr. Teddy Altman leave Grey Sloan Memorial together after many years and a complicated history.
The farewell marked the official exits of Kevin McKidd and Kim Raver, who had played Owen and Teddy for much of the show’s run. McKidd first joined the medical drama in its 5th season in 2008, while Raver debuted in season six before later returning as a full-time cast member.
The finale also gave Meredith Grey and Nick Marsh a major romantic turn, with Meredith proposing after Nick was injured during the bridge disaster. The episode once again proved that even after more than two decades on air, 'Grey’s Anatomy' still knows how to deliver high-stakes drama.
