Easy J focuses on the return of Jenny Humphrey (Taylor Momsen) and the consequences she faces from her short visit to Manhattan while Blair Waldorf (Leighton Meester) hunts her down in the hope of maintaining her social order and eschewing any possible attempts by Chuck Bass (Ed Westwick) to ruin her at the same time.

Serena van der Woodsen (Blake Lively) runs into unfortunate circumstances when she discovers that her new flame is also her college professor.

After spending the night with Nate (Chace Crawford), Juliet Sharp (Katie Cassidy) departs early so as "not to be late to class."
