Rachel Berry and Jesse St. James moved from New York to Lima, Ohio in order to start off fresh with their daughter, Mary Jane, or simply "MJ" Berry-James. As a freshman at her new school, MJ met new people and friends who welcomed her into the halls of William McKinley High. MJ loves to sing and used to be part of a show choir in New York until she moved to Lima and joined the New Directions to follow in her mother's footsteps of becoming a member there. She also met some members and friends who are children of McKinley Alumni and the original New Directions from the past years. Some of the members included Elliana Pierce-Lopez, the adopted daughter of Brittany Pierce and Santana Lopez, Andrew Hummel-Anderson, the adopted son of Kurt Hummel and Blaine Anderson and MJ's half twin-brother, Kent Cohen-Abrams, son of Tina Cohen-Chang and Artie Abrams, Chris Jones or CJ, son of Mercedes Jones, Vicky Evans, daughter of Sam Evans, Weston Chang, son of Mike Chang Jr, and Nicole and Mackenzie Puckerman, twins daughter and son of Quinn Fabray and Noah Puckerman. MJ also meets Will Schuester, the principal of McKinley High and former Glee Club Director and history and Spanish teacher. There, he will guide the new members of the glee club and offered them advice when dealing with problems. MJ knew that everything will change and she and her new friends will do what it takes to have fun in McKinley and glee club.
