[He nods - there's no point denying the obvious truth. He thought he was a better liar than this, but when confronted with the impossible, even perfect skills unravel.]

[It rankles, being called nervous. It's not untrue, but he ought to be more composed than this, to keep himself from showing such vulnerability, especially in front of a stranger. He sets his jaw in an effort to settle himself and reminds himself, over and over in his head, that Jotaro does not want to fight him.]

You sent someone to find me. A young man named Koichi Hirose. I can only assume that you wanted to track me down because of my father.

I wasn't afraid of you. But I didn't want you to know about me, either, because I was certain that you'd stop me from doing what I needed to do. So I asked Koichi not to tell you he found me. I don't believe he did.

. . . I don't quite know why.

[Except that he does. The same charisma that lived in Dio lives in him, the part of his inheritance that he's always been able to make the most use out of. That's what he assumes made Koichi's mind up, anyway.]
