She continued talking about Meredith 's evolvement as she said `` Meredith is single, and she is living this life that she 's never thought she 'd be living again. She 's living in a house with her sisters. She 's surrounded by women who are dating and having a whole life, and she 's not interested in all that.

'' Later, speaking at the Vulture Festival in New York City on May 22, Rhimes, told that she did n't know that Ramirez was leaving until they had shot the finale. She addressed Callie 's send - off and said, `` This one was different because it was n't a big planned thing, I had a different plan going and when Sara came in and said, ' I really need to take this break, ' I was lucky that we 'd shot the end of the season with her going to New York.
