"My, whatever do you mean?"
Before I start spouting any bull, let's see what he intends to do with the information first. Not like he'll believe much that I say anyway.
If he turns out to be one of those self-righteous types, then I'm in a less than favorable position right now.
With the nature of his skill, I can't just mouth off the way I usually do. His skill can tell a person's disposition, therefore, I have limited options. I can't accuse him of unjustly accusing me because it isn't completely unjustified, actually, it's completely one hundred percent justifiable.
With an alignment like Neutral Evil, there's no further room for discussion. I am a villain. It is plain as day. There's nothing much I can say to maneuver from the situation. I can only try to use it.
