I felt that Lana telling Lionel that she knows Lex better than he does was justified. Stemming from last week, we could see that Lionel is really blind when it comes to what he has done wrond in his relationship with Lex. So in the sense of seeing Lex as a creature with emotions, I don't think Lionel quite gets it.

I can agree with you that Lana probably knows Lex better as a person, because she actually sees him as a person rather than as an extension of her ego. I was objecting more to the idea that Lana knows better than Lionel what sort of threat Lex poses.

Though I suppose, thinking of it, that because Lionel created Lex he does have a blind spot to the concept that Lex could turn against him to the extent of murdering him.
