- "I guess you can say that."
- — Jeff
Jeff was one of the two Med-jacks in the Glade, the other being Clint. The two are almost always together. He is a minor character in the book, but his role was expanded in the movie. Jeff is most likely named after Thomas Jefferson.
Jeff is most prominently present when Ben is going through the Changing at the beginning of the book, when Teresa arrives, and when Minho, Alby, and Thomas are brought back from the Maze alive, as well as any other medical emergency mentioned.
Jeff was present when Teresa woke up, but she kicked him in the groin, climbed out of the window and met Thomas.
It's unknown whether or not Jeff survived the escape from the Maze or if he made it through the Scorch Trials. But due to the only listed surviving Gladers being Thomas, Minho, Gally, Frypan, Jackson, Clint, Dan, Henry, Hank, Alec, Billy, Carl, and Tim, Jeff must have been killed at some point in the Trials.
In the Maze Runner film, Jeff is shown to be one of the Gladers that goes into the Maze with Thomas to escape. Shortly after, Jeff is overpowered and killed by Grievers while attempting to save Minho. He is the third to perish in the Griever ambush.
Physical Appearance and Personality
Jeff is described as being tall with a buzz cut and a nose that is the size of a fat lemon. He was also shown to be somewhat well built and skinny.
