The Scorch Trials[]
In the The Scorch Trials, Mary was part of the Right Arm and served as their doctor and right hand to Vince. She emerged from a tent in the base to stop Vince when he tried to shoot Brenda, who has been infected by a Crank bite. She greeted Thomas and observed his reaction to her, noting that "They would put you in the Maze after what you'd done." When Thomas asked her to clarify, she explained that she used to work for WCKD and that the first time they met, he told her that he couldn't take it anymore, watching his friends get sent up and killed in the Maze after so many years. This made him turn over the information for all of the WCKD labs, bases, and warehouses to her and encouraged her to leave WCKD to try to stop them, thus forming the Right Arm.
Mary instructed volunteers from the group to help carry Brenda into the medical tent as she draws blood from Thomas to construct a temporary treatment for Brenda. She explained why WCKD was taking kids – the children were born with some kind of enzyme that made them immune to the Flare, which is why WCKD wanted to study the kids in situations like the Maze to see what would happen. Thomas asked if she's found a cure, but she reveals that the problem is, the cure could not be manmade, hence why WCKD was forced to harvest Immunes for their fluids and organs to try to concoct a cure. She injected Brenda with the mixture and explains that this was a temporary fix – Brenda will always need more. She and Jorge exit the tent to give Thomas time with Brenda, but she warned Thomas that Brenda cannot come with them.
When WCKD invaded the Right Arm's base, Mary was forced into a kneeling line with Vince and some of the volunteers. She revealed herself to Ava Paige, declaring that at least she'll die with a clear conscious. The two spoke briefly before Janson shot Mary in the stomach. Vince tried to control the flow of blood, but Mary died in his arms.
The Death Cure[]
In the The Death Cure, Mary's name was engraved on the Memorial Rock by Vince at the Safe Haven along with the names of victims from the war against WCKD. She was avenged when Janson was killed by Cranks that were freed by Thomas during the Attack at the Last City.

Scorched[]
In Scorched, Mary was working for the Right Arm, a group that is working against WCKD with the goal of stopping their plans to kidnap innocent Immune children for their tests. When Brenda asked for help, Jorge took Brenda to Mary. Eventually, both of them discovered that she is also privately testing immune children for effects to the Flare and they turn against her, refusing to help her when WCKD show up, shoot her and try to destroy the Right Arm's camp.
World Gone Wicked[]
In World Gone Wicked, Mary worked as a doctor for WCKD before Ava Paige joined the organization. She approved Mary's chemical to be distributed among people to wipe out some of the population, thus triggering the Flare. However, Mary never foresaw it mutating and evolving to the point where people had become Cranks. A year passes, and Mary shares her speculations of the disease with Paige, suggesting that there are children Immune to the effects of the disease. Ava considered that as the key for the cure to the disease and eventually started sending in a number of Immune children for testing. Seeing the number of children brought in for testing, Mary expressed her concern about them to Ava, but she assured her by telling her she is doing the right thing for the good of the world, adding that Mary is her "Right arm." Years passed and a cure seemed nowhere in sight. Ava decided to remove Mary from the project when the latter began to question her earlier intentions and work. Mary escaped, leaving Ava a note telling her that she is now working against her.
Abilities[]
- Expert Scientist: Mary used to work for WCKD as one of the leading scientists in creating a serum from harvesting immunes' blood and claimed that it works differently for everyone infected. As shown in the Scorch Trials film, Mary ordered her men to spare Brenda for she knew that harvesting some of Thomas' blood would reduce her infection from spreading further. In the Death Cure film, in the six months that had passed since Mary died, Brenda was no longer sick, as the group, including Teresa, realized that Thomas' blood was capable of destroying the effects of the Flare virus permanently.
Quotes[]
- "You know, at first, we had the best intentions. Find a cure, save the world. It was clear you kids were the key, because you were immune. But why? Eventually, we found an answer. An enzyme produced by the brains of the immune. Once separated from the bloodstream, it can serve as a powerful agent to slow the spread of the virus." Maze Runner: The Scorch Trials
