Rocha was last seen on the show in 2007, making her 2024 return to the show a comeback 17 years in the making. Her character was a slightly, overbearingly positive fourth-year resident who stepped in for Dr. Bailey (Chandra Wilson) and handled her interns – Meredith (Ellen Pompeo), Cristina (Sandra Oh), Alex (Justin Chambers), Izzie (Katherine Heigl) and George (T. R. Knight) – while Bailey was on maternity leave.

No details are known about what Heron's storyline in season 21 will be. However, it'll see her reunite onscreen alongside Wilson's Dr. Bailey – and potentially make way for a reunion for her and Meredith, as Pompeo is confirmed to appear in seven upcoming episodes as her beloved character Dr. Meredith Grey.

Pompeo has had more of a scaled-back role in the show for the last two seasons following her exit in season 19. She decided to say goodbye to Seattle and relocate to Boston in her farewell episode, only to return in the season 19 finale episode.

Fans last saw Meredith onscreen in the season 20 finale, when she resigned from her job at Grey Sloan Memorial after Catherine Fox (Debbie Allen) discovered her secret Alzheimer's research. Teddy Altman (Kim Raver), Amelia Shepherd (Caterina Scorsone) and Owen Hunt (Kevin McKidd) were also caught in the crosshairs of the controversy, leaving their fates up in the air, too.

McKidd told PEOPLE that there's a "rocky road" ahead for Teddy and Owen as they try to "come back to the hospital."

"It's a lot of fun when it happens," he teased, adding, "It causes some tension between Teddy and Owen as well. Because there's been some decisions made, but I think they're going to fight through it."

Grey's was renewed for a historic 21st season in April, extending its own record as the longest-running medical drama and ABC's longest-running primetime scripted series.

Shonda Rhimes celebrated the news on Instagram with a photo from 2015 when the cast celebrated the show's 250th episode. “To still be on your screens, in your living rooms, and in your hearts almost ten years later - words cannot express my gratitude,” she previously wrote.

“Grey’s was something I made up 20+ years ago, and I am so incredibly proud that it’s been picked up for its 21st season,” Rhimes continued. “This honestly could not be possible without you guys..caring about the stories I tell, the talented cast, writers, and crew. Wow.”
