New York, I Love You XOXO

A five-year flash forward takes place and shows the wedding of Dan Humphrey (Penn Badgley) to Serena van der Woodsen (Blake Lively).

Upon its initial airing, the finale was viewed in the United States by 1.55 million people and garnered a 0.8/2 Nielsen rating/share in the 18–49 demographic, registering as the season's most-watched episode.

Continuing where the previous episode left off, Chuck Bass (Ed Westwick) and his father Bart's argument on the roof ends with the latter falling off the building.

Jack Bass (Desmond Harrington), Chuck's uncle, comes to help him and suggests the two get married since spousal privilege prevents a wife from unwillingly testifying against her husband.

Serena van der Woodsen (Blake Lively) discovers the alternate chapter about her that Dan Humphrey (Penn Badgley) wrote and put in her bag before she left for Los Angeles.

Various characters react over the Gossip Girl reveal, including Vanessa (Jessica Szohr), Juliet (Katie Cassidy), Agnes (Willa Holland) and Lola (Ella Rae Peck), as well as Mayor Michael Bloomberg.
