Not really. He's used to demons that look like people just hanging around. Unless they do something bad (like attack someone) then he will make his move.
Also if you want even more madness I could always add Jester (AKA Arkham) from Devil May Cry 3. A demon clown that is random, rude, always making taunts. Can teleport, can summon bouncing energy balls and a giant ball that looks like his face that explodes.
Oh and he bleeds confetti.
