Persistence
Before Thomas arrived at the glade, the gladers had been imprisoned in the maze for two years. Throughout the novel The gladers never give up, they just kept on trying to solve the maze. They also knew that if any of the gladers stayed out in the maze over night, then they could possibly die, but they still tried. Thomas emerging as a leader in the glade demonstrates persistence, because he just kept trying and nothing stopped him.
Relationships
Friendships/relationships are very important in the glade. Without relationships the gladers would not be able to survive, since they rely on each other to work certain jobs for a functional society. As with Thomas, he formed many relationships, one was with chuck .Thomas and chuck had a sort of brotherly bond, Chuck believed in Thomas' abilities, and Thomas promised To get chuck home safely.Another was with Minho; this relationship helped Thomas lead the others out go the glade. However Thomas ' closet relationship was with Teresa . That had an unexplainable connection , that could possibly mean they knew each other before and their memory wasn't completely wiped.
