1 - 17: Woman on the Verge

As a result of Georgina revealing the true reason that Serena fled Manhattan for boarding school, Serena falls back into her old habits and Blair, Nate and Chuck must put their complicated feelings for each other aside to help their friend. Unfortunately, Serena is too ashamed to share the truth with Dan, leaving him only to assume the worse about his girlfriend. Rufus is thrilled when his band is invited to perform at a Rolling Stone-sponsored concert, but Lily is the last person on earth he expects to see at the performance, especially since her wedding rehearsal dinner is the same night.
