Belles de Jour

Plot:

After having spent her Parisian summer alone (and in Serena's shadow), Blair hopes to change things when she meets a handsome young man who may be a real prince. But Serena has news that may only increase Blair's insecurity. Meanwhile, back in New York, Georgina and Dan's secret comes to light, and Nate meets a girl who seems refreshingly down to earth after a summer of Chuck Bass-rejects. And speaking of Chuck, he's still missing in action, which causes Lily to worry.
