Serena: Blair, wait. Why are you so mad?
Blair: Why am I mad? You mean, why aren't I furious?! I can't believe for one second I thought that it would be different this time.
Serena: You thought what would be different?
Blair: You couldn't deal with the spotlight shining on me for once, could you?
Serena: What are you talking about? I was told that we were doing this together. What, did you not get my message?
Blair: What about this morning then? When you glanced at the call sheet, did you see my name on it? When I wasn't in hair and make-up, didn't that seem strange? When the dressing room only had your name on it, what, did you think they just forgot?
Serena: I was told that you were running late, and they asked me to do some test shots first. Blair, they told me you wanted me here.
Blair: And you believed them?
Serena: Look, Blair, I encouraged you to do this. Why would I try to steal something from you that I pushed you to do?
Blair: Because you take everything from me! Nate, my mom!
Serena: Blair!
Blair: You can't even help it. It's who you are. I just thought that maybe this time it would be different. I should have known I'd be wrong
