During the Thursday, April 30, episode of the medical drama, Richard Webber (James Pickens Jr.) revealed that he had fired Dr. Benson Kwan (Harry Shum Jr.) offscreen. The decision came after Richard discovered that Kwan illegally administered an experimental treatment to a patient against FDA orders.

The bridge collapse also has major consequences for Dr. Owen Hunt (Kevin McKidd) and Dr. Nick Marsh (Scott Speedman).
Owen takes that bridge to work,” Dr. Teddy Altman (Kim Raver) says in the teaser. Owen is then seen unconscious in a car that is slowly going underwater.
ABC previously announced that McKidd and Raver are both leaving “Grey’s Anatomy” after the season 22 finale. Although things look dire for Owen, series creator Shonda Rhimes previously hinted at a “happy ending” for the character.
“Over the years, we have had the privilege of watching Owen and Teddy’s love story evolve and deepen — two characters who always seem to find their way back to each other. It is both bittersweet and joyful to give this couple the happy ending their story deserves,” Rhimes said in a statement shared with Variety in March.
As for Speedman, he left the main cast of “Grey’s Anatomy” after season 19 but stayed on in a recurring capacity. The promo shows his character, Dr. Nick Marsh, being wheeled into the hospital on a gurney wearing a neck brace.
Speedman currently stars in another ABC series, “R.J. Decker,” which is still awaiting renewal, possibly impacting his availability for future “Grey’s Anatomy” episodes.
The “Grey’s Anatomy” season 22 finale airs on ABC Thursday, May 7, at 10 p.m. ET. Episodes are available to stream on Hulu the day after they air.
