"Two people who otherwise look almost exactly the same could have very different affiliations."<br/><br/>She considers his question, then shrugs. "Not most of them, no. And, really, mortal eyes are so easy to deceive, it doesn't take any real effort. I don't think they're doing it on purpose like that."
