He lives in a cave with his mate, it's actually clean and has blankets and pillows that he made from scrap. He doesn't like when other demons try to trespass or steal what he has collected, especially when humans try to steal or kill him. Bill, he was a lonely demon, but now that he has a mate he's happy. You, his mate, he is very protective over you. He likes to do your hair, to calm you down if you are having a rough time. He only is affectionate and loving towards you.

The baby reached it's arms for you, you were going to hold it but Bill grabbed your waist, pulled you to him and trapped you in his arms as he hisses at the baby.
