Jack

In The Maze Runner, he is seen present during the Banishing of Ben. When Grievers attack the Glade, Jack fights them off alongside the other Gladers. As Gally plans to sacrifice Teresa and Thomas to the Grievers, other Gladers rebel against Gally stating they are going to escape the Maze, and Jack leaves with the others to try to escape. He is also seen signaling Jason to come join him. He survives the Maze Trials and moves on to The Scorch.

Jack begins to build a friendship with Thomas and was tasked with looking after the injured Winston. Later, during the massive thunderstorm in The Scorch, he is struck by lightning, resulting in his leg being blown off and his hair burned. It was said that he had been clutching his knee and writhing in pain. It can be presumed that he died soon after due to shock and blood loss. This is the last place Jack is seen; during the thunderstorm in The Scorch.
