... you probably won't understand [my reasons] now, but I'll try to explain. It has to do with a duty to myself as much as anything else. I have these abilities. Most other people don't. I have a duty to use them, because I have a duty to myself to be the kind of person I would want to have as a friend. If I don't use my abilites, I'm not only failing people who depend on me, I'm failing myself.
Just say that it's a need to help... I can't not help. Not anymore, anyway. And it doesn't matter if anyone knows what I'm doing or not; I know, and I know I'm doing my best. And because of what I'm doing, things are better for other people. Sometimes a great many other people.
