The Maze Runner Wiki

Sonya is the second-in-command of Group B along with Harriet, another Group B member, in their Maze. She is the younger sister of Newt.[1] Her real name before being taken by WICKED was Elizabeth or Lizzy for short. Her role in Group B seems to parallel that of her brother's.


The Fever Code

In the prologue of The Fever Code, a young Lizzy is living with Newt and their parents in a basement. WICKED has somehow become aware that Lizzy is immune, but her parents have refused to give her up. WICKED agents force their way into the basement and demand that Lizzy be handed over to them. Her dad shoots one of them in the leg, but a woman pulls out her own weapon and shoots both him and Lizzy's mother dead. Someone says that Newt could also be useful as a control subject. Newt hugs Lizzy tightly as they are both taken away.

Lizzy is put in Group B and renamed Sonya. She is not allowed to see her brother, but unbeknownst to her, Newt often sneaks around at night and spies through a window into her dorm, making sure she is all right. When she is twelve years old, Newt, with the help of Thomas, manages to enter her dorm through a secret way and say goodbye to her before he enters the Maze. He cries, wondering why WICKED keeps them apart, and Lizzy tries to comfort him, saying that as the older one, he should be comforting her.

The Scorch Trials

Sonya first appeared in The Scorch Trials when Group B captured Thomas to kill him. Thomas convinced her and Harriet not to kill him, who then in turn helped convince Teresa.

The Death Cure

In The Death Cure, though never directly confirmed, Sonya was given back her memories. This is based off the fact that she was assigned to one of the rooms with Aris and a couple of other Gladers to remove the Swipe. Sonya helped Thomas and the others lead the Immunes out of the Maze and through the Flat Trans to get them to the Safe Haven. She escaped to the Safe Haven along with the rest of Group B and the Gladers.


The Scorch Trials

In the Scorch Trials film, Sonya, Harriet, and the other members from Group B were placed in a separate WCKD facility. While investigating the harvesting room, Thomas and Aris overhear Janson conversing with Ava Paige, who reveals that the Right Arm raided WCKD bases and facilities, one of which is likely the location Sonya and Harriet were housed. She sneaks up on the ragtag group of Gladers, Brenda, and Jorge with Harriet, holding them at gunpoint. Sonya orders the Gladers on their feet from their hiding places behind abandoned cars, but freezes when she sees Aris traveling with the group. Overjoyed, she embraces him, relieved to see him alive.

Sonya, Aris, and Harriet catch up over dinner, talking about their escapes. When WCKD raids the Right Arm base, she fights alongside the other Right Arm volunteers to defend it. Eventually, the WCKD forces overpower the Right Arm and force everyone in lines. Sonya is roughly shoved to her knees in a line with Newt, Minho, Aris, and Harriet before a WCKD soldier scans the tattoo at the back of her neck, calling out "B4." Ultimately, she is taken captive by WCKD along with Minho, Aris, and some of the other Immunes.

The Death Cure

In the Death Cure film, Sonya is among the Immunes rescued by the Right Arm when a team led by Thomas and Vince assault a WCKD train and bring the cart she, Aris, and the other Immunes were on board to their new hideout. Sonya later escapes to the Safe Haven, along with the rest of the survivors.

Physical Appearance and Personality

In the books, Sonya is described as having dark hair and very pale skin.

In the films, she has light blond hair in a side braid and hazel eyes, and is portrayed by Katherine McNamara.

As a child, Sonya loved her older brother Newt very much, and he was very protective of her. Later on, when she was twelve years old, Newt said goodbye to her before going into the Maze, and Sonya ended up being the one comforting him at that time.

Sonya often has to comfort Newt, even though Newt feel as if it's his job to protect his little sister.
