This episode was.. different.We finally know who was behind the accident. Serena and Nate put up a show to expose Trip. Nothing interesting there though. Louis's sister turns out to be good afterall.. where is the villain in this show anyway?? The worst thing though is that it looks like they're going down the Derena path again.It screams "boring!". Make up your mind, Serena! Although this episode was a little on the boring side, Leighton Meester proved how great she can be.
