Lex and Clark in “Unfinished Business”

Lex

One more thing, Clark. Lana called me. I don't want to hear you rifling through her stuff like a crazy roommate again. If you want something from me, don't go running to Lana to find it. You really crossed the line.

Clark

All those years we were friends, were you just waiting for me to step aside, so you could swoop in and make your move?

Lex

I don't know, Clark. All those years you told Lana you loved her, were you just waiting to walk away and break her heart? Look, there's a natural tendency to blame the person who's replaced you. I get that. But I didn't take Lana from you. You lost her all by yourself.
