After a summer of fun (and scandal), it's back to school on Gossip Girl this week, and from the videos we've seen previewing tonight's episode, it's not going to be pretty.

Dan has a new female admirer - until Blair Waldorf has something to say about that. Also, Nate tries to figure out what's up with Vanessa, and Chuck is... well, Chuck.

What do you expect - or hope - will go down tonight with our favorite characters?

Discuss "The Ex-Files" and all things Gossip Girl in the Insider's
