That's true about what Lex said to Lana. But Clark did say he'd protect her - no matter what.
(And , correct me if I'm wrong, but, even though Lex at least "suspects" Clark of having superhuman powers (the dagger), he still isn't aware of his "weakness" for Green Kryptonite. That was shown a few weeks back during the "cave-in" scene. So he definitely didn't know at least at the point when Lionel "threatened" Lana into the marriage, which was long before.
I mean, if Lex wanted to get to Clark, Lana sure isn't the only one around that he'd have to threaten. And Lex knows that, sure as s**t.
The whole, Lionel "protecting" Clark, and Lana believing in her way of thinking up till now, really is kind of a far-fetched part of it all. I seriously think that the writers of this show just decide to go a bunch of shows where nothing of any real consequence occurs (just the usual, soap opera and "freak-of-the-week" stuff), then they just read letters and forums like this, and then when it's time for a "big" show they just storm up a bunch of stuff that doesn't necessarily all fit or make sense, but will at least be sure to be unexpected by the viewers - I really don't think that they are writing any of this with much advance thought. I don't think they've ever had any kind of guidelines or rough draft - even for the coming final season.
A question? How come I'm not hearing anything from all the people that were so gung-ho to see Lana killed off? I thought you'd guys would be raving and thrilled. At least I can say I was - as soon as that car blew up I let out a loud warhoop!! I was actually clapping over it. The other people in the house thought I was nuts! And then I come here, and all you guys are ruining my giddiness by saying "she'll be back", and "she's not really dead". What a bunch of killjoys. Man, I was genuinely thrilled and looking forward to the fact that I wouldn't ever have to see or hear her or her $**t again! I was truly ecstatic. I was really expecting to see a bunch of posts saying "Good Riddance"!
Now we're beginning to see who here is really willing to put their money where their mouth is, aren't we
