Season 1 - Episode 17

17 - Woman On The Verge

The episode starts off with Nate and Chuck being called to Blair's house since Serena is in trouble. It is still evident that the 3 of them are still feuding. Dan is equally worried about Serena as well but everyone refuses to tell him what happened and what is going on with Serena, who had a terrible night and is staying with Blair. Serena is forced to tell Dan that she cheated on him last night, while she didn't because she claims she couldn't risk Dan knowing about what really happened to her a year ago and the real reason she left. She explains the entire story to her friends that Georgina tried to film a sex tape of Serena and accidentally recorded someone dying. Meanwhile, Lily finds the tape and assumes the worst about her daughter.

Sarah (Georgina) becomes closer to Dan because she is angry at Serena for revealing the truth behind the events a year ago.

Meanwhile, Rufus is excited 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.
