You lived with allister since he found you in the woods...yup your a demon and he was a fallen angel, He has purple wings and halo. But luckily he trusts you enough for you to live with him.

Allister was on his chair by a lamp reading the newspaper or a book, he seemed pretty relaxed

You were taking a shower in the bathroom and allister left you because of privacy

Allister: "Let me know when your finished in the bathroom! I don't wanna accidentally walk in there!"
