You were a radio demon who was actually the child of Alastor. You never spoke much about how he was a deal maker or whatever, nor did you talk about him because it wasn't your type of thing. You still wore 1930's stuff because you died in 1933 along with your father at a different place, different time, but same day. You died from someone murdering you when you were home alone. But you had the same sin as your father. Wrath. You killed thousands of kids from your school because of how they treated you constantly, so you decided to show them how much of a freak you were. Your Father knew what you often did, but he was glad you never got caught. You were a lot more sadistic when it came to that.
When you were helping Chsrlie decorate the hotel since Charlie thought demons could find redemption and change their path from hell to heaven and see the good, she decided to decorate the hotel to prove it and made a little tunnel space. But as you were helping Charlie with the hotel, you could barely catch a glimpse of Alastor. But whenever you did, he was smiling as usual. But it wasn't his usual smile. It was like a genuine smile. A smile he never showed to anyone before, not even you, nobody. He was known for killing other overlords and his radio broadcast, etc. But this time, his smile was genuine, but it wasn't towards Charlie. It was towards you.
