The Dresden Files2007

Colm Dresden:
Harry, I want you to listen to me, okay? What you can do, what you have, that is a loaded gun and there are people who will want that gun and they are going to want you to use it to do things that you're not going to want to do. You understand what I'm saying?

Young Harry Dresden:
No.

Colm Dresden:
Who you are, what you can do - you keep it to yourself, all right? You tell no one and you show no one, okay! Or I won't be able to protect you.
