He is a smart talker and well-liked by most people.
Minho is Thomas's best friend besides Teresa and Newt. Minho is the leader of the Gladers in the Scorch, as written in the tattoo on his neck. Minho is a loyal person, evidenced by the fact that he insisted on saving Thomas when he was lost with Brenda. Minho is bold and confident, but often brash. He often gets in unnecessary fights because he acts without thinking. Often, Thomas's brain-based actions mitigate Minho's rash ones.
He is the leader of the first group of Cranks the Gladers meet in the Scorch. When the Gladers first meet him, he acts arrogant and even threatening. However, he soon agrees to help the Gladers get to the cure by making a deal with them. He, too, wants the cure for his Flare.He and Brenda are very close friends. Jorge takes a liking to Thomas, who was the one to negotiate for Jorge's help in the first place. Jorge and Minho are often at odds because of how rash and bold both can be.
Brenda is Jorge's best friend in his group of Cranks. She is an older teenage girl with brown hair; she is described as very pretty, as well as very tough. She and Thomas grow very close very quickly. She flirts with him from the outset, and soon the two develop feelings for each other. She is hurt by Thomas's relationship with Teresa, however. At the very end of the story, she is also able to briefly communicate with Thomas through telepathy.
The Rat Man
Some sort of official of WICKED; he calls himself a representation of that organization. The Gladers call him 'the Rat Man' because of his physical appearance resembling that of a rodent. He is often emotionless. He is sent by WICKED to give instructions to the Gladers about the Scorch Trials. He seems to have no empathy or sympathy for the poor, tortured teenagers. He constantly emphasizes that WICKED is saving the world.
Teresa is Thomas's best friend from the Maze, as well as from before all the craziness of the Trials. She is an older teenage girl with long, black hair and beautiful blue eyes. She and Thomas also have feelings for each other, but these are put to the test in the Scorch. She acts in a confusing way in the second phase of the Trials. She ultimately makes Thomas feel betrayed, as this was part of WICKED's plan. She did it, however, in order to save him, because she cares so much about him. She and Thomas have a strained relationship after this happens.
Aris was the only boy in Group B, much like Teresa was the only girl in Group A. Aris, like Thomas, also witnessed his best friend from the Maze get killed. He and Thomas bond over this. It is revealed through Thomas's flashbacks that Aris also worked for WICKED alongside Thomas and Teresa. As a result, Aris could also communicate with Thomas and Teresa telepathically.
