Gossip Girl - Serena & Dan Save Jenny From Chuck’s Assault - "Pilot" (1x01)

At the kiss on the lips party, Chuck entices Jenny to a private stairway under the guise of wanting to get to know her better in a quieter space, but as they ascend the stairs, Chuck tries to kiss her. Jenny is reluctant, so Chuck apologizes and asks if they can start over. He offers her a glass of champagne, and she agrees, but secretly texts Dan asking for his help because she doesn't feel safe when Chuck refuses to go back to the party with her. Dan and Serena leave the concert, at which point he receives the text from Jenny. Serena, aware of Chuck's predatory nature, offers to help him find her, and together they enter the 'Kiss On The Lips' party in order to find Jenny. Blair is furious that Serena would gatecrash her party, but before she can kick her out, Nate tries to convince her not to. Blair and Serena exchange eye contact across the dance floor, in a way that seems to suggest to Serena that Blair finally knows about what she did with Nate. Eventually, Dan and Serena search upstairs, where they find Chuck forcing himself onto Jenny, as she is pinned down by him and begging him to stop. Dan, in his rage, punches Chuck in the face, and Serena warns Chuck to never touch Jenny again. As they leave, Chuck threatens Serena, calling her a slut, and reminding her that he knows everything. As they leave the party, Dan holds his sister's hand, and Serena in turn grabs Dan's, as guests look on in amazement. He inquires about a second date with Serena, and the episode then ends with Dan, Serena, and Jenny heading home in a cab together, whilst Blair and Chuck watch with expressions of anger and disgust. When the privileged prep school teens on Manhattan's Upper East Side first learn that Serena van der Woodsen is back in town the way they learn all the important news in their lives: from the blog of the all-knowing albeit ultra-secretive Gossip Girl. No one knows Gossip Girl's identity, but everyone in this exclusive and complicated vicious circle relies on her website and text messages for the latest scoop. Even Serena's closest friend, Blair Waldorf, is surprised to find that Serena has suddenly ended her self-imposed exile to boarding school and returned to Manhattan. #GossipGirl
