The next day, Serena sees another girl get one and realizes Juliet tried to keep her out on purpose. At Fashion's Night Out, she stages a fight with Blair and they expose Juliet for what she did. As a result, Juliet loses her position at the house.

In Goodbye, Columbia, Nate is studying at the house when Juliet comes to surprise him, and they have a party there that night.
