Gossip Girl's fifth season kicks off with Serena in L.A., where Chuck and Nate stop by en route from their travels.

S is actually doing well at her career there. Nate meets Diana Payne and hooks up with her, but she has an agenda.

Chuck is in full thrill seeking mode and appears to be pushing the envelope more with every passing moment.

Blair, meanwhile, is in full wedding planning mode. Louis' mom is making that a royal pain for her.

Vanessa got Dan's book published and a chapter is going to run in Vanity Fair. He wants to stop that ASAP. It's about Blair.

Louis kills the story, and Dan is about to let her leave Louis, who she believes ditched her. But they're still together.

Blair is PREGNANT. So is Dorota.
