Living out a real-life fairytale in Paris, Blair is pursued by a handsome young man, Louis (guest star HUGO BECKER), whom Blair 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 (recurring guest star CLÉMENCE POÉSY), at his side. And Juliet (recurring guest star KATIE CASSIDY) offers to help Nate win Serena back, suggesting that by reigniting the romance between Dan and Vanessa, it may remove Dan from the Dan-Serena-Nate love triangle.
