Laz didn't know what to say. He didn't know this girl, didn't owe her anything and considering what she was, should have hated her. But something inside made him want to help her.
Was it because she was pretty? Well, that didn't hurt her case. Not that he wouldn't have helped a not so attractive person, it just was easier when the person was beautiful. As for why that was? A beautiful person usually has far more pride and ego and when they beg, it triggers a dominate nature in the one they are begging. That's not to say that an unattractive person can't be prideful or egotistical, just that the sense of domination doesn't exist so the feeling of wanting to do so doesn't affect the decision as much.
Did she have something he wanted?
