My theory a/b this tool: Something ugly in his past is gonna surface and bring him down. He displays the kind of arrogance that results from having gotten away with something rotten and feeling invincible because of it. And note that his modus operandi is to always single out and focus attention on he other person  as if to say "Don't look at me, look at him/her." What's he hiding? I think we're gonna find out one of these days. I've just got a feeling...
