You create a strong tension in your micro-fiction by playing with the expectation perhaps prefixed in the reader. From the title ("The Walk"), the elements of the dialogue, the small actions including one's own walk down the aisle (we get the famous phrase, something like "Dead Man Walking"), etc. Everything comes together to fulfill the predetermined expectation in the psyche and imaginary of the reader. But you transgress it intelligently only with the small final paragraph. Bravo! Very good, @jayna!
