Nah, he wouldn't boast. It's not his style; he's confident and a bit cocky, but he ain't no braggart.<br/><br/>Though technically, I suppose it's only arrogance if he can't back it up. xD I mean, he's not<em>lying.</em>:P Lucifers job upon Creation was literally inventing and creating stars. Why do you think there's so much variety? He got bored! xD<br/><br/>That being said, Lucifer doesn't care what Alfred thinks of him. He's an old human who's going to be dead before Lucifers next sneeze anyway, so why bother sparing him even a moments consideration? :P
