(Blair and Nate walk into Chuck's room and find Serena there)
Blair: What is she doing here?
Serena: I was waiting for Nate.
Nate: Just to talk, I swear.
Blair: You said you'd never speak to her again.
Serena: (to Nate) You said that? Why would you say that?
Blair: Because you can't be trusted.
Nate: It's not Serena's fault.
Blair: Do not defend her.
Nate: I asked her to come.
Blair: Oh! Oh, so you do want to talk to her?
Nate: Yes, to explain why I'm not talking to her.
Blair: Maybe I'll leave you two to finish that fascinating conversation.
Serena: Oh! No, no, I'll go! Let you guys get back to your quickie.
Blair: It wasn't a quickie. Sex is actually kind of a big deal to some of us.
Serena: Oh yeah, I can see that, Chuck's bed? Very romantic, classy too.
Blair: Oh, like you? I'll bet your new friend Dan would love to hear all about how classy you are.
