Carter Baizen, whose motive is still a mystery, will be part of the major storyline when the show returns this Fall.
Sebastian Stan is getting a lot of camera time this upcoming season of "Gossip Girl". His character Carter Baizen reportedly will be "a major figure" in the first seven episodes of the CW show and will probably be recurring heavily in the rest of the episodes. E! Online, which has acquired this information from a source close to the show, noted that "nothing's set in stone" yet.
In the season 2 finale of the drama, Carter came to Serena's rescue when she was desperately looking for her biological father. Carter, who appeared in the show as Chuck's nemesis, finally was able to locate his whereabout and informed Serena about it. Their relationship apparently will grow stronger from there because in one of the promo pictures released for the third season, Carter is actually seen kissing Serena.
The Upper East Siders, who are now in college, will return with a new chapter of their lives on September 14. Hilary Duff will also be a major recurring character this season with her role as a movie star in disguise, Olivia. She was recently photographed filming her part at Chelsea, New York which photos are posted below.
