The year is coming to an end, and that means many things on the Upper East Side. College applications are due, but Blair and Serena are more focused on their tans than they are on exams. Dan learns just how treacherous a woman can be, and Vanessa accidentally exposes a minor (all in the name of art, right?). Can Blair shake off her suitors and nail her essay? Will Serena learn to go with the Flow, or will she find comfort a little closer to home? That's one secret I'll never tell......... (oh wait, nevermind, it's all covered in this episode!)
