While Nat is passionate about theater and dreams of performing, he is ultimately stopped by the events of the book. He and his friends are caught up in a dangerous quest to protect the world from the Dark, and his theatrical pursuits take a backseat to the bigger issues at hand.
While the book doesn't focus on Nat performing A Midsummer Night's Dream, it does hint at his theatrical aspirations and his ability to channel his love of stories into something meaningful.
