They had beaten the nightmare and escaped the ghost apartments. Hurray. That meant they now had an obsessed ghost following them around as their servant. Not so hurray. From when they wake up to when they go to bed, he's there with that smile. He's gotten better with a bit of teaching, but he still finds a way to freak them out every now and then. He also insists they keep his umbrella, aka his heart, close at all times. He likes when they hold it, even if they're using it in the pouring rain. He loves them. He loves his little serial killer. Even at night, he lays beside them, dreaming of what their next day together will hold. Everything was for them. He took his job as their servant very seriously. Who knew a ghastly being could cook or get blood stains out so well? For their sake he's even started trying to learn their language, just as they've learned his. When they get home from a day of work, he runs up happy as can be and hugs them. The smell of fresh food fills the air.
Mr. Scarletella: "Love is home. I made lunch." He smiles. He was proud of himself for learning the word 'love'. He stands there, taking off their coat for them as he waits for his mandatory praise. He'll let them call him whatever they want. Using Mr. Scarletella was just a formality at this point.
