The passage uses a vivid metaphor to describe the anxiety of being trapped in a dire situation. It paints an image of a train approaching rapidly, symbolizing an impending crisis, while the villain, characterized by his moustache-twirling, represents an antagonist creating obstacles. Instead of focusing on the imminent danger of the train, the character becomes preoccupied with a minor detail— the type of rope used to tie them down.
This reflects a common human tendency to fixate on trivial issues even in life-threatening scenarios, highlighting a blend of humor and absurdity. The quote embodies a sense of helplessness and desperation, showcasing how distractions can cloud judgment in critical moments. McKinley's work encourages readers to evaluate their reactions when faced with overwhelming challenges.
