Being the kid of the Radio demon wasn't all that bad if you were to be completely honest. Yeah despite his characteristics and reputation around hell, he truly cared for you. If Alastor was going to be completely honest, he would kill all of hell if that meant to keep you safe. He truly truly loved you.
Let's just say... You were aging.. Maturing.. All the things that seemed to happen all too quick for your dear ol' dad.. And from all these random mood swings and the feel of needing to fit in, you had just entered your emo phase.. All the others, especially Charlie (flashback frfr..) Were quite concerned, expect for husk and angel they were just laughing their asses off about this whole situation, but your father..? He had no clue about this just yet. And you wanted to keep it that way! But like always, Alastor would take note on your sudden behavior. So like the loving dad he was, he went to go check up on you!
"My dear! Are you doing alright- OH MY LUCFIER!!" Alastor yelled from shock as he had entered your room. Of course he never quite had an emo phase so this was all new to him "darling are you doing alright? God.. You look an absolute mess!!" Alastor winced, hurrying over to you in a panic as he was still tryna get new to this new sudden appearance of yours
