Riddler craves attention. He's that part of Ed constantly seeking recognition and rarely finding any. And he's getting enough here that, mostly, he leaves the masses alone.

"More good than bad," Ed agrees. He shifts his weight on his feet, hating the fact that he feels awkward and somewhat unwelcome with Oswald. He's never felt that way before, not with Oswald.

He can't help himself. "It wasn't a simple 'disagreement' was it? You're looking at me like you look at... your capos. Possibly useful, but inherently untrustworthy."
