Ep 17. Inglorious Bassterds

As the Upper East Siders gear up for prom, Chuck spends the week with his father Jack Bass, trying to figure out why Bart left him his empire. Meanwhile, Serena's date, Aaron Rose, invites her to attend a performance by his favorite artist, but Serena is hesitant to attend. Blair devises a plan to win prom queen, but quickly realizes she's not the only one with this idea. Finally, Nate and Vanessa's relationship hits a rough patch when Vanessa accepts an internship at CNN and Nate ends up kissing Jenny Humphrey. The episode's title plays homage to the Quentin Tarantino film "Inglourious Basterds," and sets the stage for the dramatic events that ensue in the Upper East Side's most iconic night of the year.
