Heroes seems to have a thematic dialogue going between fate and free will and between evolution and destiny. Portentous voiceovers begin and often end the show, discussing the mysterious forces at work in the heroes’ lives, asking hard questions such as “where does morality belong in an evolving species?” The title “Heroes” implies the moral quality of nobility, if these individuals will choose to use their powers for good. When Hiro gets a phone call leading him further into the world-saving mission, he tells his friend Ando that destiny has just called. Ando, uneasy at their increasingly dangerous mission, replies, “I wish destiny would lose our number.”
