The CW has released a summary for "The Lost Boy," the third episode of the upcoming third season of Gossip Girl. The air date for it is September 28.

In this episode, it's an Upper East Side face-off when Blair Waldorf (Leighton Meester) and Chuck Bass (Ed Westwick) both set their sights on a particular item up for bid at Sotheby's and the personal stakes are high.

What do you think that could be?

Serena van der Woodsen (Blake Lively) suspects Carter Baizen (guest star Sebastian Stan) may be up to his old habits, while Georgina Sparks (Michelle Trachtenberg) takes an interest in Dan Humphrey (Penn Badgley).

Lastly, Vanessa Abrams (Jessica Szohr) begins to have some suspicions that something isn't quite right with new guy Scott (guest star Chris Riggi).

Chace Crawford, Taylor Momsen and Matthew Settle also star. Jean DeSegonzac directed the Gossip Girl episode which was written by Robert Hull.
