"Thomas leaned back against the rough rock, overcome by disbelief at what he had just done" (Dashner 113).
Thomas ran out of the Glade and into a place called the Maze, which surrounded the Glade. Inside the Maze giant creatures called Grievers came out during the night. If the Grievers saw people, they would try to kill them. During the night, the giant walls of the Glade closed. Thomas got locked out and could not get back in until morning. Although Thomas was a little foolish, he was also brave because he left the Glade to help his friends who were already trapped in the Maze.
