Maze Runner: The Death Cure
Sonya, Aris, and the Immune teenagers are on a train headed to the Last City when Thomas, Newt, Frypan, Brenda, Jorge, Vince, Harriet, and the Right Arm rescue them and take them to their new hideout.

At night, while Sonya, Aris, Brenda, Jorge, Vince, Harriet, the Right Arm, and the Immune teenagers sleep, Thomas, Newt, and Frypan leave the hideout to go to the Last City to rescue Minho.

Sometime later, Sonya, Thomas, Minho, Gally, Frypan, Aris, Brenda, Jorge, Vince, Harriet, the Right Arm, and the Immune teenagers arrive at the Safe Haven. Sonya is picking corn with Vince when she and him see Thomas, who has woken up, approaching them. Sonya watches Thomas and Minho hug. At night, at the campfire, Sonya, Thomas, Minho, Gally, Frypan, Aris, Brenda, Jorge, Harriet, the Right Arm, and the Immune teenagers listen to Vince give a speech.

Sonya converses with Gally while Brenda sips from her cup. Sonya is sitting with Minho, Gally, Frypan, Aris, Brenda, Jorge, Vince, Harriet, the Right Arm, and the Immune teenagers at the campfire when Thomas approaches them and sits down with them. The next day, while Sonya is sleeping, Thomas goes to the memorial rock and carves Teresa's name on it. Thomas walks along the beach, stops walking, looks at the ocean and the ship, takes out the serum, looks at it, and looks out into the distance.
