Characters
Thomas. He is the strongest member of the group, according to WICKED, though he's not classified as the leader. He's a very daring individual. He is intelligent and is good at thinking things through. By the memories that are coming back to him, he can tell that he worked in WICKED, but he knows nothing about it. He is classified by his tattoo, not as a role, but as "to be killed by Group B".
Teresa. She was Thomas's best friend back in the maze, and to Thomas's little memory, even before then. She worked in WICKED with him They even share a power between them, given to them by whoever WICKED is. They can communicate to each other through their minds. She was separated from Thomas's group from the beginning and Thomas has been longing to reach her again, or even to simply talk to her through their minds, but nothing has been working. The WICKED group has classified her as "the Betrayer", for a reason that is unknown to Thomas at the beginning.
Aris. Thomas originally thinks of him as a spy for WICKED, until he tells his story of being in a maze situation that almost exactly replicated the Gladers'. He is Teresa's equivalent from the other maze. He works with Thomas's group just like any other member. He is also believed by WICKED, to be an asset in finding the cure. Thomas recognizes him once he starts having memories, so he knows that he worked in WICKED with them, also. His tattoo says he is "the Partner."
