Harriet is the leader of Group B.

Maze Runner: The Death Cure
Harriet helps Thomas, Newt, Frypan, Brenda, Jorge, Vince, and the Right Arm rescue Aris, Sonya, and the Immune teenagers and take them to their new hideout.

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

Harriet is sitting with Minho, Gally, Frypan, Aris, Brenda, Jorge, Vince, Sonya, the Right Arm, and the Immune teenagers at the campfire when Thomas approaches them and sits down with them. The next morning, while Harriet 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.
