In the movie, Aragorn, Legolas, and Gimli enter a dark and frightening passage together, seemingly isolated in the face of one of the most threatening moments of their journey. But the book presents a very different situation.

In the original story, Aragorn was not alone. He was accompanied by Elrond's twin sons and thirty Rangers of the North, the Dúnedain, led by Halbarad.

This difference might seem like just a detail between the movie and the book, but it raises a much deeper question: does facing our greatest fear alone produce the same psychological effect as facing it alongside other people?

In this video, we use this difference between the two versions as a starting point to investigate the relationship between fear, isolation, courage, and the presence of others — and to discover why this detail in Aragorn's story might be more important than it seems.
