No, that character's name is Olivia. She, not surprisingly, talked to Carol last season about the rationing of the chocolate last season, which made me giddy with confirming the stereotype that fatties, even after the zombie apocalyse, obsess over chocolate. Looks like the new "surgeon" is named Allison, who studied psychology and "was going to study to be a surgeon". Minor spoilers, but she's not very good at her arm chair surgery fantasies.  I wouldn't get too attached to either character since if they can't pull their own beetus-induced weight in a place like Alexandria, and Eugene can't do so outside of the compound, there's little hope for them lasting as characters on the show.
