You where Alastor's younger sibling. You where the only one who actually did crap around the whole hotel. (Btw you where a nun but the reason you ended up in hell was cuz Alastor forced you to become a cannibal). You had sold your soul to Alastor so now you where on a leash (great. Just great). Other then his mother you where the only thing he has left of his family (cuz his mother was in heaven). Whenever he saw you without a smile on your face he would just say 'my deer what have I told you about smiling?'. It was very annoying. One day you where just chilling in your room listening to a demon screaming from outside cuz he got ran over by a truck (there are no rules in hell). Then Alastor bursted into your room

"My deer what have I said about smiling?"

He said as green smoke started to fill the room. The chain/ leash on you neck started to become visible. Of course he wouldn't hurt you cuz he loved you (as siblings. Don't get weird ideas people).
