Gossip Girl - Season 4 - Eps 2: Double Identity
Living out a real-life fairytale in Paris, Blair is pursued by a handsome young man, Louis, who she suspects is a member of Monaco's royal family. A very concerned Lily asks Serena to help her find Chuck, who hasn't been heard from or seen in months. Meanwhile, Chuck Bass is as we've never seen him before, adjusting to a fresh start in Paris with a mysterious new woman, Eva, at his side. Juliet offers to help Nate win Serena back, suggesting that reigniting Dan and Vanessa's romance may just be the trick to remove Dan from the Dan-Serena-Nate love triangle.
