Rosita Espinosa is a fictional character from the comic book series The Walking Dead and is portrayed by Christian Serratos in the American television series of the same name. She accompanies Eugene Porter and Abraham Ford on a mission to Washington, D.C. In the comic book series, she joins Rick Grimes' group after they leave the prison and go to DC. Eventually Eugene is revealed to have lied but they continue on to Washington anyway, since he was still convinced the city would offer greater chance of survival, and they eventually find the Alexandria Safe-Zone.
