<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>
