Jeff

Portrayed by Jacob Latimore.

Jeff is a Med-jack.

He is one of two Med-jacks, the other being Clint. He is usually seen in the background with Clint. He and Clint told Thomas that Teresa, who has arrived in the Glade, is throwing rocks at Gally and the other Gladers.

After the Griever attack (Massacre), Jeff was one of the few Gladers to go with Thomas into the Maze. While Minho is giving Teresa and Chuck the code, he is attacked by a Griever. Jeff saves him by stabbing the Griever with his spear, but is then eaten alive by the same Griever seconds later. Jeff is the third and final Glader to die in the escape from the Maze.

In Maze Runner: The Death Cure, Jeff's name is seen engraved on the stone of the deceased.
