Lex and Lionel [in Clark] in “Unfinished Business”

Lex

Clark, you don't seem like your usual self. You barely said a word the entire ride home.

Sorry. Being in that prison... I guess it upset me.

Lex

Yeah, well, it isn't exactly the happiest place on earth.

No, it isn't, Lex. Do you ever feel guilty? Sending your father to prison, I mean.

Lex

Why would I? The man murdered his parents. I did society a favor.

And that blood relationship, it doesn't mean anything to you?

Lex

Clark, since when did you become president of my father's fan club?

You're right. Of course. He's only your father. Why should you feel anything?
