I think if it hadn't been the book, it would have been something else," he said with a little nod of his head, fingers of one hand brushing over Walter's collarbone. "We'd have ended up lab partners in a class, or partners for a project, or something. I'm sure of it." Not that it mattered, because Walter had lost his book and Nicholas had found it and that was that.
