Dark power...

Lionel: You have survived mortal injuries
so many times. How else can you explain it?

Lex: Because I was trained
never to accept defeat. When I get my hands on that box
in Zurich I have a feeling all my questions
will be answered.

Lionel: Lex? I know how strong it is, the attraction
of the dark power. His evil side?
But it will destroy you. I can't let you go down that terrible path.
