In The Maze Runner, Winston is introduced as the Keeper of the Slaughterhouse.

He follows Thomas to escape the maze and survives.
In The Scorch Trials Winston is first made notable in the events following the entrance into the Flat Trans, where he and another Glader, Frankie, are attacked by a liquified metal that seeks out and solidifies on contact with a human head.
