‘Grey’s Anatomy’ Introduces a Shocking Hospital Investigation Before Season Finale

Grey’s Anatomy is shaking things up at Grey Sloan Memorial Hospital with a concerning investigation ahead of the season finale.

During the Thursday, April 2, episode of the hit ABC series, Miranda (Chandra Wilson) tried to hide the fact that Kwan (Harry Shum Jr.) secretly gave a patient an experimental treatment that was denied by the FDA.

Miranda’s husband, Ben (Jason George), was the first to catch on and then Richard (James Pickens Jr.) caught wind of it. He called Miranda into his office — not knowing Kwan was at fault — to warn her of an official investigation into the incident.

Kwan’s future at Grey Sloan Memorial Hospital was called into question after news broke that Kevin McKidd and Kim Raver are leaving the show at the end of the season.

Creator Shonda Rhimes hinted at how the season will wrap up for Teddy (Raver) and Owen (McKidd) in a statement last month.

“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,” she teased. “Kevin and Kim bring extraordinary talent, nuance and heart to their roles as Owen and Teddy. Their contributions leave an indelible mark on Grey’s Anatomy, both in front of and behind the camera. I’m so grateful to have had the opportunity to work with them both and to see them shine.”

She concluded: “While we will all miss seeing them in the halls of Grey Sloan Memorial each day, I am excited to witness where Kim’s and Kevin’s journeys will take them in the future.”

Grey’s Anatomy has faced plenty of cast shake-ups this season alone. Amelia (Caterina Scorsone) chose to take a sabbatical after the shocking death of her colleague Monica (Natalie Morales). It was subsequently reported that Scorsone’s break would last until the end of 2025 as the result of a cost-saving measure.

The show is already reducing the minimum guarantees for its veteran cast members to 14 out of its 18 episodes per season. While some of Grey’s Anatomy‘s consistent stars will be missing for four episodes, Scorsone’s absence was doubled.

Showrunner Meg Marinis previously hinted that not every character would be safe this season.

“But even in the last two seasons with what you saw this year, we had to reduce the cast a little bit [because of industry-wide budget cuts], and everybody has very passionate feelings about their favorite characters,” Marinis told The Hollywood Reporter in May 2025. “But if we can get the writers upset then we know we’re doing it right. It’s not as satisfying a story if people aren’t upset when someone leaves. It’s supposed to make people upset and sad, so I’m sure there’ll be some arguments. But I’ve been persuaded before to change my mind on things.”

Grey’s Anatomy airs on ABC Thursdays at 10 p.m. ET before streaming the next day on Hulu.
