Momsen plays Jenny, Dan's trouble-making younger sister who was shipped off to Hudson to live with her mom earlier this season in light of her recent bad behavior. After teaming up with Jenny and bad girl Juliet to take down Serena last year, Szohr's character Vanessa has had little to do on-screen besides pine for Dan from afar. The character is about to leave town to study abroad.

In light of the departures, recurring guest star Kaylee DeFer, who plays Serena's cousin Charlie Rhodes, will be promoted to a series regular in the fall.
