Serena: What's Chuck doing today?
Blair: Why are you asking me?
Serena: Well, you guys are friends. And, Blair, you know you can tell me anything. I'd be the last person to judge anyone.
Blair: With good reason.
Serena: Blair, I saw you with Chuck.
Blair: [pauses] I don't know what I was thinking. I mean, sleeping with him once, maybe I could understand. But twice?
Serena: Wait, you slept with him!?
Blair: Shhh.
Serena: Blair!
