Gossip Girl Recap "Monstrous Ball"

Sage entreats Blair to help drive a wedge between Steven and Serena, and Blair plants the idea in Lily's head that Serena is rushing into it, and the next thing you know, Gossip Girl reports that Steven is seen leaving Harry Winston without the ring. It's just Sage's doing (and it actually helps smooth things over between B and S), but she does something even worse when she overhears Georgina and Dan talking about the sex tape. Once she gets her sneaky little hands on it, it makes quite the creative accompaniment to her debut.
