what happens at the end of maze runner 2
Maze Runner: The Scorch Trials The group eventually arrive at The Right Arm's outpost relief camps, where other innocent survivors are present, and are greeted by Vince, who leads the Right Arm and is in charge of deciding whether they can stay or not. As Brenda's infection gets worse, Vince threatens to shoot Brenda, only to be stopped by Mary Cooper, a former WCKD scientist who reveals that Thomas was their informant, which also helped the Right Arm in taking down WCKD's illegal major operations ever since. As Mary halts Brenda's infection using an enzyme cure, Mary explains that the enzyme can only be harvested from an Immune's body, not manufactured, and that arguments over the methods of manufacturing the cure with Ava led to Mary's departure from WCKD. That evening, Teresa tells WCKD of her location, believing that WCKD's motivations are good, leading to an ambush by WCKD. Ava and Janson arrive and confront the Right Arm before WCKD troops capture survivors for experimentation, including Minho, Sonya and Aris, while Janson shoots Mary dead. After Thomas and the Right Arm fend the WCKD troops off, Ava, Janson and Teresa retreat with their captured survivors. With only a fraction of survivors left at the site, Thomas plans an infiltration into WCKD and is determined to take them down to save his friends and save civilization, as his friends and the Right Arm agree to help and prepare to fight back.
