when do serena and blair became friends again
Serena van der Woodsen The first season introduces Serena as the beautiful, wealthy daughter of divorced parents who returns from boarding school. Her return sparks her old rivalry with her best friend, Blair. Serena's return is due to her younger brother, Eric van der Woodsen, who attempted suicide, and is considered unwelcome, most so by her old best friend Blair, who has always seen Serena as a threat to her reign as Queen Bee of Constance. After Serena successfully reconciles with her, Chuck Bass reveals to Serena that he knows the cause of her sudden departure prior to the first season - taking Nate Archibald's (Blair's boyfriend) virginity during a wedding,[9] and he attempts to kiss her. Serena manages to escape and runs into Dan, a St. Jude's student from Brooklyn, who often expresses cynicism about the lifestyle his wealthier classmates lead. Serena also finds a friend in Jenny Humphrey, Dan's younger sister. Nate eventually reveals his tryst with Serena to Blair, and Serena is ostracized in the first few episodes of the show.[10] Blair and Serena consistently fight and reconcile throughout the show's subsequent episodes, often dealing with Serena's tendency to overshadow Blair.[11] Serena and Blair reconcile after a heartfelt confrontation that prompted Serena to admit her mistake with Nate and leaving Blair in her time of need.[12]
