Smallville, Season 4

Lionel:
How's Lex? I've been trying to contact him since I heard, but he won't speak to me.

Clark:
He thinks you're trying to frame him. Are you?

Lionel:
No, Clark.

Clark:
Why should I believe you?

Lionel:
There's no reason you should. Listen to me. I was ill, Clark. The liver disease I had was a death sentence. And something happened. I can't explain it. I woke up on the floor. There was a riot. I felt as if a different kind of energy had been inside me. Something strong and... good. I was changed. And my liver had healed.

Clark:
What was it?

Lionel:
I don't know. All I can say was... it was miraculous. I could see the darkness, the destructive power that had always been inside me. I can see it in Lex now.
