The episode was written by Jake Coburn and directed by Lee Shallat-Chemel. It aired on Monday, October 25, 2010 on the CW. 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. Plot The episode begins with a Blair Waldorf dream sequence of Wait Until Dark with her as Audrey Hepburn being attacked. However, unlike in the film, her attacker is, strangely, a blond female. Blair awakes to find Serena with an unmade bed, messy hair, and adorning the same clothes from the previous day. Serena admits to having spent the night with "The Cab Stealer.", Colin Forrester (Sam Page). However, they spent the night talking of pop art in lieu of sleeping together. Serena says she refuses to be one of the women he hands off in a cab every morning. Blair explains her dream to Serena, who believes it to be about recently becoming Chuck's active target. Blair is unsure, however, and wonders aloud why the attacker would be female. After spending the night with Nate (Chace Crawford), Juliet Sharp (Katie Cassidy) departs early so as "not to be late to class." Nate is disappointed, hoping to have spent more time with her. Via phone, Dan (Penn Badgley) assures him it's probably the truth. As Nate ends his call with Dan, getting in line to visit his Dad in prison, he spots a sheepish Juliet. Jenny returns to New York, only to face an angry Blair – willing to do anything to make "Little J" leave town again. On her way to class, Serena spots her fling, Colin from the night before while entering the building. Irked, Serena is further thrown off by the revelation that he is her Psychology of Business professor, a fact that threats their relationship. Blair visits the Van Der Woodsen residence and runs into Jenny. Outraged that Jenny is breaking the rules
