[Ren cocks his head at the question, his expression blankly confused at the notion he's trying to impress anybody. It's genuine - there's a variety of reasons for it, but that's not one of them.] Impress...? I never really had to work to impress anybody in my world, so it's never been that...

[He taps his chin thoughtfully, as if deciding how to explain. There's part of it that he's definitely keeping to himself for now; as much as he likes Molly, Ren's extremely cagey about giving specifics on what he's done in the past. So he can't exactly say that he restrains himself because he knows exactly the kind of person he can be if he lets the wrong side of him out too far, and it's not the kind of person that's any fun for anybody involved.

As such, he decides on one of his other reasons to explain it, one he thinks might help Molly understand better.] If people think you're harmless, it makes things a lot easier...people treat people they think are a threat or just suspicious a lot differently than they do someone who seems like they're not completely there or too kind to take advantage of them, right? And to make that work, I have to be pretty careful about who knows what I'm really like. Does that make more sense?
