Gossip Girl - S3E11: The Treasure of Serena Madre

What's the Story?

It wouldn't be Thanksgiving on the Upper East Side if there wasn't a serving or two of some major drama for the holiday. Blair suspects her mom has been keeping a big secret from her, but it turns out to be something else entirely. Vanessa is supposed to spend Thanksgiving with her parents, but has a fight with her mom and shows up on Dan's doorstep. Rufus learns that Lily has been lying to him about her mother, Cece. Chuck tells Nate that he has some potentially damaging information about one of their friends. Jenny learns that Eric was behind her very public embarrassment at Cotillion and can't pass up a chance to get even. Serena is put in a very awkward position when her mother invites Trip and Maureen to join them for Thanksgiving dinner.
