Nate is a 10-year-old boy who is a newcomer to Colson, California. He dislikes being relocated and separated from his school friends. Even though he begins the story as an outsider, Nate quickly makes himself a part of the Blue Falcons—a club consisting of Summer, Trevor, and Pigeon. Unlike his new friends, he stands up to the three bullies who make their lives miserable. Although his role is never stated, Nate seems to be the group's natural leader. He takes on more risk and responsibility during their various exploits, including control of inanimate figures using Proxy Dust.

Nate also takes the initiative to consume the Grains of Time, which ultimately results in Belinda White’s defeat. He has more direct interaction with both John Dart and Sebastian Stott throughout the story and also agrees to continue working for Mrs. White in an effort to learn her true plans. Nate proves his loyalty to his friends by willingly sacrificing himself to bring Trevor out of the mirror world, even though this might cost him his liberty. In the final analysis, Nate’s quick thinking frees everyone from Mrs. White’s influence and restores balance to the world.
