I think that a good case can be made that Devon Brown benefited the most from being sent to Kenya. One of the film's basic premises is that the kids from an urban center like Baltimore, with its limiting capacity, benefit greatly from their own imaginations being expanded. The ability to conceive of themselves in a different light than what is understood and expected is what enables their stories to be so transformative and powerful.
After the experience of Kenya, Devon embodies this in his own life. As of 2010, he attends an institution of higher education. In attending the Maryland Institute of College of Art, Devon has dedicated his life to transforming what is into what can be. He wishes to be a film director, which is a profession steeped in making what can be from what is. At the same time, Devon has political aspirations. He is considering running for City Council, enabling him to be in a position to help others and provide further "blessings" for others. In these changes, one can see that Devon has taken the lessons from his experience and applied them to his own life and in hopefully changing the lives of others for the better.
