I want to ask a question about The Maze Runner.Why doctor Ava Paige wanted so badly Thomas and his friends?and i want to do me a favor.I want to make me a summary about these movies i mean The Maze Runner and both of them.Thank you so much bye!!

Thomas and his friends are a part of an important experiment. The Glade is an experiment. WICKED is using the group entrapped in the Maze to study their minds. The group will not be allowed to escape, merely transitioned without their knowledge into the next phase. Ave needs Thomas and the others, as they are the subjects of her experiment.

bascially there is this horrible disease called the flare that is taking over the human race and WICKED wants to preserve human race so they study a bunch of kids who are "immune" to the virus and they go through a bunch of trials so WICKED can study their brains to find a cure for the flare.

This question is explained in The Fever Code, which explains wha Ava Paige is, what Thomas' real name was, what the Purge was, and much more.
