Heroes, Season 3 (Volume 4: Fugitives)

Mohinder:
For every being cursed with self awareness, there remains the unanswerable question, "Who am I?" We struggle to find meaningful connections to one another. We are the caring friend, the loving father, the doting mother, the protected child. We fight and we love in the hope that somehow, together, we can understand our significance in the universe. But in the end, no one can share our burden. Each of us alone, must ask the question, "Who am I? What does it mean to be alive? And in the vast infinity of time, how do I matter?"
