Smallville, Season 5

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.
