What does Frannie say about the new boy's appearance as he looks around the room?

She says that he's calm and quiet in a way that she's never seen on a kid before. She notes that he looks directly at Trevor even after Trevor said a rude word about the new boy. Trevor glares but the new boy continues his calm perusal of the class. When he meets Frannie's eyes, Frannie smiles and the boy's returns a "tiny, calm smile."
