I too loved the exchanges between Luthor and Clark. On the surface it's all pleasant conversation, underneath there are secrets, lies and the butting of horns between two men attracted to the same woman.
I so dearly wanted to see that last scene through Clark's eyes, but we haven't seen his POV at all in this story so of course there will be things left out.
