Blair’s hosting a ball. Serena calls to invite Dan and overhears Dan talking to a female. When she asks who he’s talking to he says his sister, who it isn’t because his sister has just walked into the room Serena is sitting in. She knows he’s lied and ends the conversation before asking him to go out. Dan, why did you lie, you jerk! We later find out the girl is names Vanessa and she’s Dan’s ex. The two make plans to see a movie.
Blair’s running Jenny around like a slave making arrangements for the ball for Blair. One of the stores loans her a bracelet because they assume she will be going to the ball and they want her to display the bracelet. It’s full of real diamonds and she really likes it. Blair tells Jenny she is not invited to the ball. When will Jenny learn she’s being used?
Nate discovers drugs in his fathers things. He had previously asked his father where his trust fund money went and his father covered and told him he was moving money around and lo and behold the money was back the next day.
In the meantime, Blair tells her minions to find Serena a date.
Rufus goes on a non-date with Serena’s mom. Rufus realizes that he’s being used to make Chuck Bass’ father jealous. I have a sneaking suspicion that these two are going to be getting together some time in the future.
Jenny sneaks into the ball, as does Dan after canceling the movie by lying saying he had a paper to write. Dan interrupts Serena’s date, tells the truth and they kiss. Vanessa sees the two and looks crushed. As it turns out, she thought Dan still loved her. He tells her that was the past. She leaves, and like a jerk he follows. Meanwhile, Jenny’s gotten a little payback on Chuck by baiting him into taking off his clothes. She locks him on the rooftop in his boxers.
Serena and Jenny exchange masks and now look similar. Nate tells Serena he still cares for her, but it’s Jenny he’s talking to. Jenny runs out, with Blair thinking she’s Serena until her bracelet comes off. She is not pleased.
Dan and Serena meet back up and make peace. Dan and Vanessa agree to figure out how to be friends. Nate goes home and discovers his mother also found the drugs, except his father didn’t admit they were his so his mother thinks he’s using.
