„The Trackers were on the move again, spreading out to search. It sounded like a trio on each side of the train, coming toward him.
Gold-Eye pictured them in his head, trying to get his Change Vision to show him exactly where they were.
But the Change Vision came and went when it chose, and couldn't be controlled.“
