When they arrive at the "event," the group discovers that it's actually a brothel — and Blair is quick to step in when a woman approaches Chuck. Jealous, perhaps? Serena dials Gossip Girl's number, but Diana sees them in the building and an alarm system goes off, clearing everyone out. Upstairs, Chuck finds Jack and demands to know the truth: "Are you my father?" As usual, Jack avoids the question.
Meanwhile, the gang realizes that Diana is the madam of the brothel and that she goes by "India." Serena tries to post the story on Gossip Girl, but she left her laptop in the downstairs dressing room and — surprise, surprise — her password is locked. Nate and Lola confess that they've set her up so that the real Gossip Girl can return to her job. She's angry, but Nate argues that they did it for her own good. The real question: why on earth would Serena have brought her computer?
