Despite Thomas’ protestation, Alby has Teresa placed in jail for triggering the changes. Thomas tries to defend her, but Alby says that he is lucky to not be thrown into the Slammer along with her. As Alby calls for two guards to take her to jail, she tells Thomas telepathically that he should come and see her. He tries to respond with telepathy as well, reassuring her that the Slammer is a safer place to be, but receives no response from Teresa.

Mass confusion spreads over the Glade. The Gladers are preoccupied with trying to seal the Doors in order to prevent the Grievers from getting inside, while everyone is moved inside the Homestead for safety. Thomas feels that everyone is working hard so that they can keep from panicking. He helps the Builders first and then helps Minho carry weapons into the main building. When Minho leaves, saying he has a special assignment, Thomas goes to see Newt and tries to convince him that Teresa is innocent. Newt says that if they can survive the night, he will try and free Teresa from the Slammer.
