Blair is serious about trying to run her mother's fashion line, but she falters in a big way when she's interviewed for Women's Wear Daily. Nelly Yuki turns out to be the WWD reporter, and she doesn't exactly have fond memories of Blair from high school. Through this, Blair discovers that Poppy Lifton (yes, Poppy Lifton is back) is now a fellow designer, and she thinks that Poppy stole her designs. It's all a fashion coincidence, though, and by the end of the episode, B decides to do the impossible and create a new line in 10 days. Someone get this girl Tim Gunn's cell number.
