If you have the Scorch Trials on DVD, you have probably looked at the Extra Features section. There are some really cool things there. 

One section are Jansen's Files: For Future Generations. It has Thoms, Newt, Minho, Fry-Pan, and Aris talk about what they know about WCKD and what's happening in the world around them. It also tells their labels.

Thomas-To be killed by WCKD

Newt-To be killed by WCKD

Minho-The leader

Fry-Pan-The Side-Kick

Aris-The Partner

One of the deleted scenes id Jack's death. In the books, he was struck by lightning, but in the movie, he was going to die when they're all escaping the cranks when Minho turns on the lights. In the scene, he made everyone go before him on the escalator and a crank pushed him off. He held onto a ledge, but another crank jumped and pulled him down off a ledge. Obviously, the film makers had the actors for this scene wear a harness and wires, but they could have at least edited the mat and the wires out.

You can see the green screen.

Okay, you know how when thy're in the truck and Newt is in the front seat? It has nothing to do with the storline. They shot that scene right after the one where they get Marcus to tell them where the RIght Arm is hiding and while everyone eles was happy that they got through the shoot without laughing, Thomas Brodie-Sangster called shotgun.
