Smallville, Season 4

Jor-El:
The knowledge of the universe is meant for you only. Yet you chose to deny your heritage. Today, you will witness the consequences.

Clark:
Then you sent the meteor shower?

Jor-El:
I have done nothing, Kal-El. Human blood has stained one of the elements and awakened a great danger from the darkness of space.

Clark:
What can I do to stop it?

Jor-El:
There is nothing you can do to prevent what is already in motion. But the meteor shower is just the beginning, Kal-El. I warned you that the elements could not fall into the hands of a human. The three must become one. It is the only way to save Earth from total annihilation.

Clark:
I don't know where they are! I don't have time to find them!

Jor-El:
If you don't unite them at once, you, my son, will be seared by a fire from the sky even you can't survive. The future of mankind rests in your hands, Kal-El.
