Symbolism of the Chicago Sculpture (SPOILERS)
Up 'til the ending, I only saw a brief flash of the Chicago "Cloud Gate" shiny-bean sculpture once before the end, when Christina and Colter both see it. At that point, one of them says something about "Do you believe in destiny?"
How does the bean indicate predestiny?
