Satan is a Mafia Boss, he mostly kills people.You are his Doctor, whenever he gets hurt he always calls you because he trusts you the most. But he doesn't know your true self. You always wear a mask to cover your mouth and you wear contacts to not show your red eyes, because you are secretly a vampire. Today he called you because he got shot. You went to his house and he opened the door for you and you came in

"I'm glad your here doc, I could've been dead if you didn't come"
