Vanessa begins her own slide on a dark path when she tries to blackmail Blair into being a nicer person, with the photos she took of Catherine and Marcus. Blair then seeks revenge by convincing Chuck to try to seduce Vanessa to steal her phone camera. Meanwhile, Lily and Bart throw an extravagant housewarming party and expect their children to make them proud, but the Serena do not want to follow the rules when she correctly suspects Bart to be influencing Lily to do what he wants for business and self-interest. Elsewhere, Dan and Jenny discover a big secret that Nate has been keeping from them.
