You've Always Counted

Sherlock: You're wrong, you know. You do count. You've always counted and I've always trusted you. But you were right. I'm not okay.
Molly: Tell me what's wrong.
Sherlock: If I wasn't everything that you think I am, everything that I think I am, would you still want to help me?
Molly: What do you need?
Sherlock: You.
