Serena: Blair.
Blair: What? You want a lift to JFK?
Serena: Your mum said you were going to France tonight.
Blair: She has a big mouth.
Serena: But I'm your best friend. She was shocked I didn't know.
Blair: Well now you do.
Serena: All I know is how you felt when I left without telling you.
Blair: Is there a reason you're here?
Serena: Stay. Don't let some stupid scandal make you run away like it made me. Like it does everyone in our world.
Blair: Everything's horrible. My whole life is falling apart.
Serena: So rebuild it! You're a Waldorf remember? People don't tell you who you are. You tell them. Stay and fight. I'll fight with you.
Blair: I'm so embarrassed. I'm so..
Serena: So what? Start over. It can be done. I should know. We can get through this together.
Blair: You promise?
Serena: Promise.
