Thomas and Minho get back mid-morning to find that the Glade is functioning as close to normally as possible.
Newt rushes to greet them with childlike excitement that they might've found something, but he gets his hopes dashed when they report that nothing has changed.
Their suspicions were correct: the Grievers had attacked during the night and had taken one boy.
Minho loses hope and freaks out, and Thomas checks on the Map decoders and finds they've completed their task.
The code consists of six words: FLOAT, CATCH, BLEED, DEATH, STIFF, PUSH. Well, that hardly makes any sense.
Apparently the Maze has been repeating those words for months, and they know FLOAT is the first one because after PUSH the Maze wouldn't show any letters for a week before starting over.
Thomas is frustrated by the indecipherable message, and then a horrible idea strikes him. He has a terrible plan: he's going to get stung by a Griever so that he can go through the Changing and get his memories back. On purpose.
