Billy isn’t physically imposing, and while he has an impressive mind and impressive vocabulary, he also has all the social skill of a sea cucumber. Being homeschooled and an only child, he doesn’t know what to do now that he has to live with them on a regular basis for most of the year. He’s much more likely to respond by withdrawing into himself and minding his own business than he is to even attempt to be outgoing with his fellow students. He is also very, very difficult to manipulate, primarily because he’s naturally suspicious of people and because he’s so intellectual and spends so much time inside his own head.
