Looks like some magical moments are in store on Gossip Girl!

When Blair Waldorf's (Leighton Meester) dad, Harold (John Shea), comes home for the holidays with an unexpected guest - boyfriend Roman (William Abadie) - Blair finds it difficult to hide her disappointment.

Meanwhile, Jenny (Taylor Momsen) and Vanessa (Jessica Szohr) help Serena (Blake Lively) plan a Christmas surprise for Dan (Penn Badgley), who may have a surprise of his own in mind for Serena. Chuck (Ed Westwick) texts Blair that Nate (Chace Crawford) has joined him in Monaco.

Lastly, we'll see if Rufus (Matthew Settle) remain an understanding, forgiving husband after Alison's (Susan Misner) former lover calls the house.
