The dude's literally in tears. I didn't even flesh out the character. Get this, he's a teacher, but had to quit his job because the students reminded him too much of his own children, who were tragically killed in a car accident only 2 years earlier. Destiny was the only thing that kept him going. Collecting those flakes became a metaphor for putting together the pieces of his shattered life. He thought that by completing the raid, he could finally move on.
