After being held in solitary confinement, Thomas is eventually released by Janson (nicknamed the "Rat Man"), who is the assistant director of WICKED (World In Catastrophe Killzone Experiment Department). Janson tells the Gladers (Group A) and Group B that most of their number are immune to the Flare, but some, whose names he reads, are not immune, including Newt. The Gladers are offered the chance to remove the mind-control chips in their heads and restore their memories but at the cost of Thomas's ability to communicate telepathically with Teresa and Aris. Only Thomas, Minho, and Newt choose not to undergo the surgery, as they do not trust WICKED, and Thomas does not want to know who he was when he helped to create the maze. All three of them escape from WICKED with the help of Brenda and Jorge before their chips are removed
