This week's episode opens with a dream sequence, but this time, Serena is the dreamer. In it, she plays Marilyn Monroe and Blair is (who else?) Audrey Hepburn, and the men in their lives are dressed in tuxedos as an homage to Gentlemen Prefer Blondes. To Serena's disappointment, that's apparently not the case for Dan. He chooses to follow Blair upstairs and Serena wakes up, disheartened. A bit of foreshadowing for things to come?
