Straying away from the novel that doesn't offer a cure in the end, Teresa comes up with an antidote in the movie. Observing a sample of Thomas' blood under the microscope, Teresa is able to confirm that it can destroy the Flare Virus.
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].
So as clichéd as it may sound, 'The Death Cure' ends the 'Maze Runner' series on a bang - not just in terms of being a wall-to-wall explosive finale from start to finish but also by giving the characters a proper sendoff.
Paige came to realize that they would never be able to find a cure for the Flare and that WICKED's efforts were futile. She realized that the only hope of preventing humanity's extinction was for Immunes to start their society, away from the rest of the world.
The disease eats away the minds of the afflicted until they turn into Cranks, zombie-like creatures that roam cities killing people until they're killed themselves. Fortunately for Thomas, he and most of his friends are Munies — immune to the Flare. That's why they've been put through the Maze and the Scorch trials.
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.
They discovered that Gally was immune to the Flare virus and decided to bring him to the Last City to help nurse him back to full health from the Griever sting and being stabbed by Minho. The ultimate reveal that Gally did not die in The Maze Runner was briefly set up in the original movie.
Thomas tells the Keepers that he and Teresa were manipulated into designing the Maze because they share the gift of telepathy. He convinces the others that he and Teresa are now in as much danger as them, but he knows the way out. Thomas tells them in order to escape, they have to jump through the Griever Hole.
Due to its current development status, Maze Runner 4's release date is unknown. Disney has never given the film a date on its schedule, even though the studio has releases mapped out through 2027. This might mean that the earliest Maze Runner 4 could be released is 2028.
Straying away from the novel that doesn't offer a cure in the end, Teresa comes up with an antidote in the movie. Observing a sample of Thomas' blood under the microscope, Teresa is able to confirm that it can destroy the Flare Virus.
The ending reveals that Thomas escapes with a vial of the cure for the Flare virus, but it becomes symbolic rather than crucial, as many survivors are already immune and no one is capable of harvesting the cure.
It was originally set to hit cinemas on 17 February 2017. However, when Dylan O'Brien suffered injuries during filming, 20th Century Fox pushed back the release to 26 January. The accident, which happened in March 2016, saw a stunt involving two cars go horribly wrong, leaving O'Brien seriously injured.
After the completion of the original trilogy, author James Dashner began work on a prequel series of books to The Maze Runner. The first of these prequels was titled The Kill Order and was released quickly after The Death Cure in August 2012.
Newt reveals that the reason WCKD put him in the Maze was because they wanted to tell the difference between immunes like Thomas and people like himself. Thomas tells Newt that he can cure him.
Disease Immunity: Teresa Agnes was shown to be immune to the deadly Flare virus and its effects. In Death Cure, when Ava Paige announced that the virus was airborne in the city dozens of the people wore mouth masks to be unable to breathe it, except for Teresa due to her immune gene keeping her unaffected.
Gally got through the same way the other Gladers got through. Gally used the small mechanical device that was found in the dead Griever body. We know this because when Gally appears at the end he is holding it.
In the Scorch Trials Newt was poked with a syringe that supposedly gave him the vitamins he was deprived of. Then, in TDC Newt's source of infection came from the exact spot that the needle was placed and injected. The way to spread the disease is to bite or transfer fluid to another.
Newt really did die in the Maze Runner Series. He died in the third book, The Death cure. There are five books in the series. The Maze Runner, The Scorch Trial, and The Death Cure being the main three.
The emotional intensity is definitely doubled up in the movie, establishing Teresa as a Thomas' one true love interest. Unlike Dashner's original story, the possibility of him dating Brenda is eliminated, and the audiences also get enough time to process the death of a character introduced right from the first movie.
The books center on Thomas, a 16-year-old boy with no memory of life before the Maze, the friends he makes in the Glade, and their struggles to survive a series of deadly tests and overthrow the corporation running them.
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.
The only named people that I can find that reached the haven or whatever, the paradise at the end of the death cure, is Brenda, Jorge, Gally, Minho, Frypan, and presumingly Sonya unless she died fighting the WICKED people at the end.
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.
