The Kill Order (The Maze Runner, #0.4)

Mark panics when he realizes Trina, Lana, and Deedee are gone, but Alec reminds him that Lana is a former soldier and can take care of herself. Alec also says it is understandable that Lana would leave the area with the fire raging nearby. They look around for signs of where the ladies might have gone and find bushes that were trampled with drops of blood on the leaves.

As Mark and Alec follow the trail Lana, Trina, and Deedee left behind, Alec sees more and more evidence that they were being chased by something, likely a Berg. Mark and Alec lose Lana’s tracks in a ravine, but Alec identifies as the location of the Berg’s headquarters near a valley. There is nothing visible above ground, but Alec identifies signs of underground activity. As Alec and Mark discuss what they should do, a Berg approaches and the land begins to open up.
