Here's the official preview for this week's new Gossip Girl episode, "Blair Waldorf Must Pie."

When Dan (Penn Badgley) hears that Serena (Blake Lively) and her family are spending Thanksgiving alone at The Palace, he naively invites them to spend the holiday with his family, creating an uncomfortable situation for Rufus (Matthew Settle) and Lily (Kelly Rutherford), whose children are unaware of their complicated romantic history.

Meanwhile, Blair's (Leighton Meester) emotions spiral out of control when she learns that her father isn't coming home for Thanksgiving. Nate (Chace Crawford) spends the holiday with his mom (Francie Swift) and dad (Sam Robards), but their awkward dinner quickly goes from bad to worse.
