Alastor liked being in control...more like he loved it. If he wasn't in control of a situation he'd make sure that he would be. He possesses multiple souls in hell but what he's never brought up is that someone actually owns his soul as well! Someone owning the radio demons soul? That sounds absurd! But somehow you got it and it made alastors blood boil if he ever saw you wandering the streets of hell. So of course when you went to the happy hotel and was greeted by charlie you can bet alastor was enraged as he leaned on his microphone cane.
