When the bell sounded, Tyber put a bookmark in his book and then closed it, stuffing it back in his bag. He then waited for class to start, his eyes always searching for something that wasn't clear; he kept looking toward the door, never turning his head fully, and subtly looking around his desk. It almost seemed as though he was trying to figure out how fast he could get up from his desk and out the door if he suddenly had to run. But with all of this, he was just as calm and collected as ever.
