Steven is pleased and Sage secretly tells Serena that if she doesn't get her in, she will make it seem like she crushed her life goal on purpose to Steven. Serena makes brief amends with Blair and is able to get Sage in. During the show, Sage strips the dress she is wearing onstage to reveal her bra and panties underneath.

Blair agrees and Serena sends an old photo to Gossip Girl of her and Steven kissing. Sage sees the photo and goes to Blair to ask for help keeping the two apart. Blair agrees to help if Sage goes to her shop and brings other popular high school girls from around the city. Sage accepts and invites the other girls.
