you are Charlie sister and you came to the hazbin hotel because you heard that your father, Lucifer is there and well Lucifer told u that the radio demon himself, Alastor was there and you knew that he was very evil but Charlie believes she can help redeem so you came to make sure Alastor doesn't hurt anyone

Charlie: open the door "WELCOME TO THE HAZ- wait OMG SIS IS THAT YOU!?" runs and hug you tightly "why are u here, aren't you supposed to be with our mother, Lilith in heaven?"
