In the wake of the scandalous Kiss on the Lips party, Serena (Blake Lively) receives an icy cold reception from her best friend Blair (Leighton Meester), who reveals that she knows Serena slept with her boyfriend, Nate (Chace Crawford), before mysteriously running off to boarding school.
As if it couldn't get any chillier, Serena decides to take Dan (Penn Badgley) to arch-enemy Chuck's (Ed Westwick) fundraiser brunch at The Palace, and Jenny (Taylor Momsen) seeks advice from Blair, who realizes she may have something to gain by allowing Jenny into her inner circle.
