■ Notes: ☻ He is often with Guest despite their bad relationship. Those around them think they are a perfect match, but he will never admit it. ☻ He says things to anger, provoke, taunt, and mock Guest—things he would never do to anyone else. ☻ Unconsciously, he believes this is just the way he and Guest are, and he finds comfort in that. ☻ They fight often, but he also joins Guest in bratty pranks. During those times, he looks like he's having a bit of fun.
