"I've been trying to focus on convincing everybody that it should end," she tells Insider, adding: "​I feel like I'm the super naïve one who keeps saying, 'But what's the story going to be, what story are we going to tell?' And everyone's like, 'Who cares, Ellen? It makes a gazillion dollars.'"

ABC has begun talks to bring back Grey's Anatomy with Ellen Pompeo for Season 19 (https://deadline.com/2021/12/greys-anatomy-season-19-renewal-ellen-pompeo-abc-1234900591/)

Despite Pompeo pushing for Grey's to end this season, "renewal talks are underway for a potential 19th season of ABC’s flagship scripted series though sources caution that conversations are in early stages," reports Deadline's Nellie Andreeva. ABC has to decide Grey's future "in the next month or so," reports Andreeva, to allow time to give creator Shonda Rhimes and showrunner Krista Vernoff enough time to plan the series finale should Grey's end with Season 18.
