The nonwhite Greek chorus of the candycoated Upper East Side universe of 'Gossip Girl' giggled as they snapped cellphone pix of Serena and Dan's makeout session, but once more, their behind the scenes plot-advancing role was not rewarded with lines of actual dialogue. Will we ever be allowed to know the inner lives of Black Girl and Asian Girl? Or will their exploits continue to be overshadowed by the forbidden love affair between Dan and Serena, who come from such different worlds that they go to the same school and also their parents used to bone? Good thing the new Judith Butler-Gayatri Spivak book comes out the day before next week's episode: Maybe that will help us puzzle things through.
