Smallville, Season 2

Martha:
My son is in jail. And your wife put him there.

Lex:
Maybe these fires were a cry for help.

Martha:
Is that you talking, or is Mrs. Luthor talking through you?

Lex:
Mrs. Kent, I would never ask you to take sides against your husband, please don't ask me to doubt my wife.

Martha:
Any good relationship relies on trust, but there has to be room to disagree. Like the way Jonathan and I disagreed about you. He couldn't see past the Luthor name, but I always thought you were truly trying to be a friend to Clark. Now I'm beginning to think Jonathan was right all along.
