Behind my shadow.

-You idiot! You don't surprise someone standing off the edge of a building!

-No one cares. 

-I do. Don't you understand? I'll always be here. I don't want you going anywhere. I couldn't bear it. So whatever you want to do to yourself, please don't do it to me. Please. Whatever you're going through, I wanna be there for you.

-We've talked about this. You are not my girlfriend.  

-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.  

-And why would you do that?

-Because I love you.
