Jor-El : Listen carefully, my son, for we shall never speak again. If you hear me now then you have made use of the only means left in you: The crystal source through which our communications begun. The circle is now complete. You have made a dreadful mistake, Kal-El. You did this of your own free will in spite of all I could say to dissuade you. Clark Kent : I, uh... Jor-El : Now, you have returned to me for one last chance to redeem yourself. This too finally I have anticipated, my son. Clark Kent : Father, no... Jor-El : Look at me, Kal-El. Once before when you were small, I died while giving you a chance for life. And now, even though it will exhaust the final energy left within me- Look at me, Kal-El. The Kryptonian prophecy will be at once fulfilled. The son becomes the father, the father becomes the son. Farewell forever, Kal-El. Remember me, my son.
