Clark and Martha in “Unfinished Business”

Clark

It also means the prophecy came true. The blade glowed and disintegrated when they touched it, which means either Lionel or Lex is my greatest enemy.

Martha

Did you see which one grabbed it first?

Clark

No. But I don't need a blade to tell me that Lionel Luthor is a bad person.

Martha

If you're going to believe this legend, you have to face the possibility that it could be Lex.

Clark

I'm not ready to do that.
