Luke is discovering that he’s entirely unprepared for life outside his attic bedroom—he has no idea how to talk to Jen, and he doesn’t know much about various cultural assumptions, such as how a girl named Jennifer should act. Particularly because it feels like Jen is speaking a different language, Luke is terrified and wants nothing more than to go back home, where he knows he’s safe and where he knows how to act. He’s beginning to see how big and varied the world is, and due to his sheltered upbringing, this is a lot to take in.
