<P> Critics responded positively to the development of Pierce in her centric episode "Puzzle With a Piece Missing". Fempop gave a largely positive review writing, "Puzzle With a Piece Missing is a funny and insightful look both into this latest interloper and the established characters of Grey's ." praising the new addition, "Thankfully she's (Pierce) her own person, confident and happy to bring the thunder and put everyone, from interns to the chief of surgery, into their places ." </P> <P> Entertainment Weekly lauded the episode stating, "Coming into the second week without Cristina Yang, Grey's was smart to focus all of its attention on the newcomer . With most other main characters only making occasional cameos, it made it more difficult to feel Yang's absence . And by showing Maggie's side of the story, it made her more relatable . It was a win - win ." adding on McCreary's character, "this episode is about how Maggie is her own, very likable person ." </P> <P> On her character TV Fanatic wrote, Overall, we got to know Maggie a little better and it's nice to see that she's made some friends . It was a fair episode that showed Maggie's basically a work in progress . Maybe she'll grow on us eventually ." </P> <P> For the thirteenth season, Vulture writer, Maggie Fremont spoke positively about the character: "It's never easy for a long - running series to introduce a new character, especially when that character is meant to immediately fit in with the rest of the ensemble . But when Maggie Pierce arrived in season ten, that's exactly what Grey's Anatomy did . It could've been easy to dislike her--she showed up to take over cardio as Cristina Yang was leaving, for chrissakes! She was yet another one of Meredith's long - lost sisters . The cards were really stacked against Maggie Pierce . Yet, thanks to the writers and Kelly McCreary's terrific performance, Maggie was immediately endearing . She is weird and neurotic and cheerful . She is nothing like Cristina, but she fills a void that Meredith needs filled in order to function . Can you really imagine Grey's without Maggie Pierce?" </P>
