Rorschach is definitely one of a kind, living or dead. He's been dead almost as long as he was alive, so he had some perspective on why he was still around. He's been anti-social for so long and it hadn't helped him move on or find closure at all. Maybe this half-baked kid has a point.

That actually gets Rorschach thinking. Who does he like to be around? He's only ever had one real friend in his life. Well, he'd always had the Watchmen around, even when they didn't want him around. It makes the first part of the answer obvious. "Hunters. People who can see me. And children." Sorry, Ghoul, it's a very short list. Be glad he managed to come up with three on his own.
