While one of the main protagonists of the first film and the second film, Teresa steps up to the role of anti-villain in the climax of the second film, when she allies with WCKD but in the third film she re-allies with Thomas and his friends and becomes a protagonist once again.
Teresa's betrayal of Thomas leads to several Gladers being taken by WCKD, setting up a third movie. At the end of Maze Runner: The Scorch Trials, WCKD's attack against the Right Arm leads to Gladers like Minho, Aris, and Sonya getting captured.
The subsequent explosion in The Death Cure's ending results in the building caving in, eventually killing Teresa. What makes her death memorable is that she still manages to save Thomas and even hand him the serum that contains his own blood (the titular “Death Cure”).
It was revealed that Teresa and Aris could talk together using telepathy during Phase One in the Maze. Aris also has a part to play in this forced betrayal. In the end, Thomas, Newt, and Minho refuse to trust or forgive Teresa, even though she tells them she did it because she didn't want Thomas to die.
Assistant Director Janson, also known as simply Janson or the Rat Man in the books, is the main antagonist of The Maze Runner franchise. He was the highest-ranking official in the organization WICKED under Chancellor Ava Paige's command.
Described by Thomas as a bully, Gally is hotheaded and arrogant, constantly threatening the other boys with violence. Despite his flaws, Gally cares deeply about the safety of the Gladers, sacrificing his own life to prevent the Grievers from killing any of the other boys.
However, none of the Maze Runner movies ever explain why WCKD sent Teresa into the Maze. It seems improbable that she betrayed WCKD since she defends them fervently. In Maze Runner 4, the story could provide clarity about whether Teresa went into the Maze voluntarily and the purpose of her presence.
I'd never say Teresa was wicked or evil. She was obsessed with the prospect of helping and healing and finding a Cure. That is not bad. She only failed to see that WICKED is wicked, and that torturing people is the wrong way.
Newt gets scratched by one of the Cranks on his right forearm, consequently infecting him with the virus. How does Newt get infected on Maze Runner? So of the guys who were originally in the Glade in the books, most of them were already immune to the Flare.
Teresa is very similar, someone who is so focused on WICKED's cure, that she doesn't care how many she has to take down, be it a group of Cranks or her best friend. They lack the characteristic known as 'being human', and that is what makes her so despicable.
She spends most of the end of the book apologizing to Thomas for what she did, and still, we don't know if we should believe her or not. Thomas, too, has trouble forgiving her.
I think it's understandable that they kissed since it's the last thing they expected to do in life. Kaya has pointed out, however, that Teresa and Thomas don't have some kind of super-romantic lovey-dovey relationship. On the contrary, their relationship is probably best described as "complicated."
Characters. Thomas (books 1–3, 5, minor appearance in book 4) is one of the creators of the Maze along with Teresa Agnes, and later a Group A Glader in books 1–3. He is the main protagonist of the series, named after Thomas Edison. Thomas's name was Stephen before WICKED took him from his mother.
Teresa's willingness to make personal sacrifices for the greater good of the group further cements her status as a character with strong moral qualities, making her a "good" person within the intricate narrative of the Maze Runner series.
It is eventually revealed that Thomas' blood contains a unique enzyme that can destroy the Flare virus [2]. In "The Death Cure" film, Teresa, one of the main characters, uses a small fragment of Thomas' blood and observes under a microscope that it snaps a dark-red vein with the virus in it, effectively killing it [2].
Throughout the novel, even in the face of life-or-death challenges, Thomas exhibits intelligence, strong problem-solving skills, and a desire to fight for his own survival and that of those around him. Through his actions, Thomas proves himself to be trustworthy, reliable, and resourceful.
Thomas agreed to the mission, but later became disillusioned with WCKD after witnessing the suffering of his friends in the glade. He resolved to rescue them from the maze, which led to his proposal of being sent into the glade as part of a plan to gather information and eventually rescue his friends [2].
Gally's hatred of Thomas is ultimately driven by an unwavering commitment to rules and safety, as well as a deep desire to uncover the truth of the Gladers' circumstances.
He runs away from the Glade in a fit of rage after exclaiming that he thought Thomas was not to be trusted in the Gathering. At the end of the book, he kills Chuck when he tries to save Thomas from being hit with a dagger.
Sometime after being left behind in the WCKD lab by the Gladers, Gally is found still lying on the floor with the spear still in his chest by a crew, who, after discovering that he is immune to the Flare, pull the spear out of his chest and take him to the Last City to meet their leader, a Crank named Lawrence, who ...
