ANAHEIM, Calif. -- It's been two decades since Seattle Grace Hospital opened its doors. Since that time, a lot has happened.

Doctors died in a plane crash, LVAD wires were cut, and a bomb was removed from a body. D23 LIVE UPDATES : Latest from Disney's ultimate fan event Through it all, the show has remained fresh, introducing new characters and plot lines along the way, while still retaining its heart and a few original members. On Saturday, at D23's "Grey's Anatomy: 20th Celebration" panel, the cast gathered to share memories of their years on the show.

The panel included new showrunner Meg Marinis and actors Chandra Wilson (Dr. Miranda Bailey), James Pickens Jr. (Dr.

Richard Webber), Caterina Scorsone (Dr. Amelia Shepherd), Kim Raver (Dr. Teddy Altman), Kevin McKidd (Dr.

Owen Hunt, Camilla Luddington (Dr. Jo Wilson) and Jason Winston George (Ben Warren). As an ice breaker, the cast was first asked if they could remember which surgery was their first on the show.

Wilson, instead, shared a story from season 1 about how she sat in on a 5-month-old baby girl's heart surgery to repair a hole. While she initially thought she'd be up in the gallery, like doctors do in the show, she was actually on the floor in the room where it took place. "I got to just stand there and watch this beautiful sort of bloodless procedure done in order to repair this baby girl so she could go on and live a good life," she said.

"And so I was good. I was like yeah that's right, surgeon, that's me." As.
