The CW has released a series of photos from next Monday's Gossip Girl episode, "Despicable B," in which Blair feels like her UES status might be slipping away and devises a plan to assure that doesn’t happen.

Meanwhile, Lily throws a family gathering in an attempt to prove the van der Woodsen family is as united as ever, and Nate digs into Diana’s past through seductive means and is surprised by what he discovers.
