"I just want to help." It's as simple as that, for him. And it feels wrong, somehow, for her to think she needs to be more like him. In the next moment, not knowing what else to say, he moves a little closer, using the brim of his hat to shield her from the patter of the rain.

"I wasn't always like me." That's it. That's why. She shouldn't think that he just came into being like this, that he didn't have to learn. "Before I knew what I was... I did bad things. I was wrong, and I didn't know it. Ghost in the shadows, dagger in the dark... but I didn't know I was wrong until someone showed me I could be right. I don't want it to happen again, but it isn't bad that I didn't know before. I just didn't."
