Blair and Serena in “All About My Brother”

What happened? What's wrong? Talk to me.

[Serena starts crying] I can't.

Of course you can.

[sobbing] No, no, B, this is the one thing I can't tell you. I can't tell anyone.

I'm not anyone. I'm me, you can tell me anything.

[sobbing] No I can't, because then you'll be a part of this and I can't let you be a part of this.

What are you talking about? You're starting to scare me.

Hey, hey, hey, we're sisters. You're my family. What is you is me. There's nothing that you could ever say to make me let go. I love you.

What is it?

I killed someone.
