Adam was mentioned by Newt in The Maze Runner. He was taken by Grievers the day after Gally was taken. Thomas felt guilty for feeling no sorrow at the news of Adam's apparent death, as he did not know the boy. He appeared in the background of most situations.

In The Maze Runner (film) Adam's name is crossed out after the Griever attack.
