Gossip Girl (2007): Season 2, Episode 1

2 - 1: Summer, Kind of Wonderful

As the summer draws to a close in the Hamptons, Serena and Nate have everyone fooled into thinking they are a couple to cover up the fact that Nate has been hooking up with an older, married woman named Catherine (guest star Madchen Amick). Blair returns from abroad with a hot guy on her arm (guest star Patrick Heusinger), making a very jealous Chuck question his decision to leave Blair stranded at the heliport. Dan has spent the summer assisting a famous author (guest star Jay McInerney), and clearly still has one certain girl on his mind, which results in him going after her. While interning for Eleanor Waldorf's company, Jenny sneaks an invite to a much-coveted Hamptons' White Party at which Eric introduces her to socialite Tinsley Mortimer.
