The Backup Dan

The episode received mixed reviews, with critics praising the scenes between Penn Badgley's Dan Humphrey and Leighton Meester's Blair Waldorf as entertaining but noting the uncomfortable pattern of Blair continuing to be bought and sold by her love interests.

The wedding reception of Blair (Leighton Meester) and Prince Louis (Hugo Becker) continues from the previous episode.

Serena (Blake Lively), Chuck (Ed Westwick), Nate (Chace Crawford) and Lola (Ella Rae Peck) search for Blair who has disappeared from the reception.

Still in her wedding dress, Blair starts to attract attention from passersby in the airport so she claims she and Dan are royal decoys.

Louis gives a press conference asking for the public's help finding Blair so she and Dan decide to wait for Dorota at a hotel.

At the same time at the Waldorf apartment, Princess Sophie (Joanne Whalley) tries to get Eleanor (Margaret Colin) to tell her where Blair is by reminding her of the dowry in the prenuptial agreement.

Surprised, Serena drops her bag, revealing the camera with the video of Blair professing her love to Chuck.

Music featured in the episode included Future This by The Big Pink, Like a Virgin by Madonna, New York City by In Waves, Try by JoAnna James, Wait by M83, and War by The Temporary Thing.

Huffington Post's Laura Prudom thought the episode was not as successful as the previous one, calling the story "choppy and strangely paced" as the action jumped around between characters in different locations.
