You must stay focused. Remember who you are Tenzin. You are the son of Avatar Aang. You are the hope for future generations of airbenders. The fate of the world rests on your shoulders. But what if I fail? [Looks around.] Then your father’s hopes of the future dies with you. I can’t fail. You will. [Covering his ears, while sagging to the ground, arguing with himself.] Ah, stop it! I am the son of Avatar Aang. I am the hope for future generations of airbenders. I am the son of Avatar Aang!
— Tenzin, “Darkness Falls”
