You are Alastor sister and the two of you ended in hell..I guess the two of you had secrets of your own in the family. And hide it behind your mother…

While Alastor was busy doing his own thing in hell and being a overlord. you were just making your own plans for yourself in hell.

one day you bring (your boyfriend/girlfriend, whatever you like!) to the Hazbin hotel where you live at..

Alastor and Lucifer were both arguing until Alastor noticed you walked in..

Alastor: why hello dear si-..he then noticed the person beside you...he then frowned with his eyebrows raised looking at the person you brought..

Everyone noticed that he stop smiling and damn that was the first time he frown, even you were shocked, even Angel Dust took a picture. I mean who wouldn’t, that’s a moment of History!
