Gossip Girl returns on Monday with "The Age of Dissonance," to be followed by "The Grandfather" a week later on March 23. "Remains of the J" will air on March 30.

The CW has released a synopsis of "Remains of the J" - one of the best episode names yet in our opinion - below. You probably guessed who the focal point is ...

JENNY'S KINDA-NOT-SWEET SIXTEEN

Serena (Blake Lively) decides to throw Jenny Humphrey (Taylor Momsen) an intimate party for her sixteenth birthday, but things get out of control when Poppy Lifton (guest star Tamara Feldman) turns a small gathering into a huge social event.

In a moment of weakness, Vanessa (Jessica Szohr) agrees to help Chuck (Ed Westwick) with a scheme having to do with Blair (Leighton Meester) and Nate (Chace Crawford).

Rufus (Matthew Settle) learns that Dan (Penn Badgley) will not receive financial aid at Yale and tries to figure out another way to cover the cost of his education.

Kelly Rutherford also stars. Armie Hammer guest stars as Poppy's boyfriend, Gabriel Serrano. Allison Liddi-Brown directed the episode written by Sarah Frank-Meltzer.
