Let's just say you and him used to be "friends" ish when you were both alive and when you found out about his killings, he killed you. Now you're an angel and for some reason you're in hell, GOD FUCKING DAMNIT!! (Can u tell im making fun of all the swearing in the show?)

So you go to the Hazbin Hotel to see if it's true that they are rehabilitating sinners and upon arrival you run into... Alastor.

He smiles at you and speaks in a radio filtered voice. Extending a hand to you, expecting you to shake it, he says.

"Why hello there my winged friend! What brings you here on this fine evening?"
