He is also blind. When his 11-year-old son, Tommy, is found to have cancer after breaking his arm during a baseball game, Brian is devastated. Having no faith in God, he feels angry and lost. Rev.

During his running sessions with Clayton, Brian vents his frustrations about his son being sick, and questions a God who would allow this to happen.
