Blair: Whatever you’re going through, I wanna be there for you.
Chuck: We’ve talked about this. You are not my girlfriend.
Blair: But I am me. And you are you. We’re Chuck and Blair. Blair and Chuck. The worst thing you’ve ever done, the darkest thought you’ve ever had, I will stand by you through anything.
Chuck: And why would you do that.
Blair: Because I love you.
Chuck: Well, that’s too bad.
