This creates several possible explanations for what the audience just witnessed.Banks-Waddles confirmed that the scene is meant to be ambiguous. Some viewers might see it as Will imagining an older version of himself during a moment of worry and doubt. Others might interpret it as a guardian angel or spiritual guide offering encouragement. The thematic purpose was to reassure Will that everything he learned in Bel-Air would help him move forward in life.What would the ending have been without Smith?
