"In short, we don't know what his name is. We also don't know what he looks like, so there's no way to find him by name and appearance. Of course, we don't have a single clue as to who his family was and where they lived… We don't have anything... We can only use what we know to find him. However, he has to know what we know. Otherwise, even if he finds out that we are looking for him, he still won't know that we are looking for him. Does that make sense?"
