Thomas wakes up in a box with no memories, and finds himself in a place called the glade with a maze surrounding it. The next day Thomas spots Minho and Alby trying to make it out of the maze, but notices that Albys injured. As the doors to the maze start to close he makes a huge mistake... he enters the maze.
Then a couple days after he came back, a girl showed up in the box which has never happened before. Her name was Teresa, and she had immediately fallen into a coma. Thomas had a strong feeling that he knew her from somewhere and strangely enough they did have a connection, a telepathic one.
WICKED is good
Thomas figures out that the maze is all a code, and that they need to go through the Griever Hole. Newt, Minho, and Thomas then leads a large amount of gladers into the maze to escape.
