In the Realm of the Basses - S2.E14

Because Chuck is MIA since his father's funeral, his Uncle Jack arrives on the Upper East Side to find and help him. Trying to forget her last conversation with Chuck, Blair focuses on being accepted into the most prestigious ladies club in the city, Colony Club. Jenny returns to Constance Billard and immediately takes on Penelope and her posse of mean girls, but no one is going down without a valiant Gossip Girl-worthy fight.
